Waterford County Council Water Services Investment Programme Assessment of Needs 2007-2009
______________________________________________________________________________________
1.0 INTRODUCTION
Local Authorities were required to prepare an updated Assessment of Needs for water
services capital works in their administrative areas in 2006 in view of the scale of
development in recent years. The last such assessment by Waterford County Council
was undertaken in 2004. It covered the period 2003-2006, and has provided the basis
for scheme approval and scheduling under successive Water Services Investment
Programmes.
In order to measure progress since the last assessments were completed, and to
facilitate phased advancement of the Investment Programme up to and during the next
National Development Plan 2007 – 2013, this report identifies a new Assessment of
Needs. The assessment is in accordance with the general guidelines set out in the
Department of the Environment, Heritage and Local Government (DEHLG) Circular
L2/06 and takes fully into account the following:
Relevant National and EU environmental, public health and water quality statutory
requirements.
The provisions of the Waterford County Development Plan 2005 – 2011 and
various Local Area Development Plans for Waterford.
The National Spatial Strategy.
The South Eastern and South Western River Basin District Management System.
The Sludge Management Plan for Waterford.
The County Waterford Rural Water Strategy.
The National Water and Urban Waste Water Studies.
The need to support Economic and Commercial Activities, and
Annex 12 of the EU Commission‟s application to the European Court of Justice in
respect of Ireland‟s implementation of the Drinking Water Directive.
The primary objective of this assessment is to develop an overall strategic investment
plan for the medium to long term for the Waterford County Council administrative
area, and to set out a programme of works required to meet the identified water
services needs. Water services needs include drinking water, wastewater disposal and
storm water management.
The 2006 Census recently published by the CSO shows a population increase of 9.2%
over the 2002 to 2006 period in County Waterford. This increase was greater than the
national average (8.1%), the provincial average (6.5%) and the regional average (8.7%).
It was also significantly higher than the population increase in Waterford City (i.e.
2.6%). This increase was concentrated in the areas near Waterford City, Tramore and
Dungarvan, along the coast and in mid-County Areas. However, all rural areas in the
county showed an increase in population. The total population of Waterford County
Council„s administrative area was 62,167 in 2006, an increase of 5,215 on 2002 figures.
The steady growth in population, commercial/industrial development and tourism in
the County Waterford area over the most recent assessment period has placed
pressures on the capacity of the Council‟s water supply and wastewater treatment
systems to meet growing demand.

______________________________________________________________________________________
It should be noted that Waterford Local Authorities devote significant resources to
ensure that water quality is maintained at the highest standards. To this end Waterford
County Council operates a management and control system to ensure that water
intended for human consumption is wholesome and meets the requirements of the
Drinking Water Regulations. The aim of this system is to optimise the treatment and
provision of drinking water, and to prescribe procedures for dealing with breaches of
water quality standards, particularly with regard to ensuring public health is protected.
This is achieved by the provision of a detailed monitoring programme as follows:
Process control monitoring at treatment plants carried out by plant operator.
Verification/surveillance monitoring of treated water, by Waterford County
Council Laboratory located at the Adamstown Treatment Plant.
Regulatory monitoring of raw and treated drinking water by the Health Board on
behalf of Waterford County Council
Surveillance monitoring of drinking water quality by the Regional Water
Laboratory on behalf of Waterford County Council.
Ancillary monitoring programmes such as Nitrate surveys and groundwater
surveys.
The most recent published report on the quality of drinking water in Ireland for the
Year 2004, notes that, “the overall rate of compliance in Waterford County Council, 95.1% was
below the national average during 2004. The reason for the lower overall quality is the lower than
average microbiological quality of drinking water. There were 11 incidents of E-Coli contamination in
11 public water supplies in Waterford County during 2004 in the Ardmore-Grange-Ballybrusa,
Ballinacourty/Deelish, Dunhill, Dunmore East Regional, Graiguerush, Joanstown, Kilcooney,
Kilgainey, Shanacoole and Stradbally supplies. All of the incidents reported were moderate with the
exception of the Ballinacourty/Deelish and East Waterford Regional incidents in which high levels of
E-coli were detected.
Though compliance with chemical parametric values in public water supplies was generally satisfactory
there were exceedences of the arsenic and nitrate standards that were of concern. Elevated levels of
arsenic were detected in two public water supplies (Ballyogarty and Kill/Bunmahon) while there were
elevated levels of nitrate in two supplies also (Ballyogarty and Adramone)
Compliance with indicator parametric values was below average particularly in the public water
supplies. The main feature of the monitoring results for indicator parameters was the low level of
compliance with the pH parametric value. A total of 40% of the samples analysed in public water
supplies were outside the permitted range.”
The EU Water Framework Directive, which is now being transposed into Irish Law is
an exceptionally important piece of environmental legislation and seeks to ensure that
waters in Ireland will be protected. Waterford County Council is involved in both the
South Eastern River Basin District and the South Western River Basin District and this
work has also been taken into account in the Assessment of Needs. The Serviced
Land Initiative introduced by the Department of the Environment Heritage and Local
Government has also been taken into account as it applies to Waterford County
Council.

______________________________________________________________________________________
This report includes a summary of the achievements of the Water Services Investment
Programme from 2003 to 2006, and an examination of the main requirements for
water services investment over the period 2007-2014.
This report includes a prioritised list of projects with outline descriptions, cost
estimates, marginal cost assessments and details of the objectives of investment in
terms of the outcomes sought and specific outputs required, to be implemented over
the 2007-2014 period.
2.0 BACKGROUND
2.1 Water Supply
There are currently 103 public water supply schemes in County Waterford many of
which are impracticably small for management purposes. 85% of public water supplies
have less than 100 connections, which highlights the difficulty of supplying water to a
predominantly rural area. In terms of production Waterford County produces
approximately 43,500 m3/day with a little over half being exported to Waterford City
from our East Waterford Water Supply Scheme. The majority of the smaller schemes
depend on relatively small independent water sources with varying levels of
vulnerability to pollution that require significant time and resources to manage on an
ongoing basis. In addition the smaller schemes cannot sustain leakage and are a large
drain on resources, as a single leak of 10 l/min can equal the normal output of a small
scheme. The available resources to manage the large number of schemes is often
stretched and consequently numerous water supply schemes have had isolated water
quality compliance failures mainly relating to chlorination equipment failure or isolated
local pollution instances. This is reflected in the 63 Public Water Supply Schemes that
recorded non-compliance with the Drinking Water Directive over the last 5 years as
listed in Annex 12 of the EU Commission‟s application to the European Court of
Justice in respect of Ireland‟s implementation of Directive 80/778/EEC (the Drinking
Water Directive) which was appended to Circular L11/03.
Current Water Supply Deficiencies:
Many of the water supplies within the county are deficient in one or more respects as
follows:
Difficulty in the operation and management of supplies due to their age, diverse
nature and extent (103 No.). Amalgamation and rationalisation of sources,
regionalisation of supply networks and treatment is essential to increase the level of
service, improve efficiencies and facilitate increased levels of monitoring and
maintenance.
Distribution systems that are old and subject to constant breaks and leaks. This is
highlighted by the fact that our 14 largest water supply schemes are currently
running at 40% leakage with ongoing leak detection and repair in place while many
of the smaller schemes are running at 80-90% leakage. This results in unnecessary
overtaxing of sources and a substantial reduction of supply pressures. A further
3

______________________________________________________________________________________
knock on effect of this excessive leakage is the ability to extend current public
schemes to amalgamate existing group schemes seeking take over. This is an
unsustainable approach that will lead to more acute supply difficulties as demand
increases and existing distribution systems age.
Inadequate or no storage leading to major supply problems with resulting
difficulties for consumers, industry and tourism. This is a major problem at peak
summer demand for some of our schemes. For example, many areas of the
Ballinacourty/Deelish scheme experienced severe reductions in level of service for
several weeks last summer in Clonae strand, a major tourist area.
Inadequate and sometimes no capacity for fire fighting due to small diameter
mains. Virtually all of our small schemes have no realistic fire fighting capabilities.
This is obviously an unsustainable situation.
Increasing nitrification of groundwater supplies, which has resulted in some being
shut down, for example, the Crooked Bridge and Lefanta boreholes, which
provided necessary augmentation for the Ballinacourty/Deelish and
Lismore/Cappoquin/Ballyduff (L.C.B.) schemes respectively. In addition, elevated
nitrates at the Monument borehole currently serving the Cappoquin portion of the
L.C.B. scheme and the Ballyhane borehole currently serving the adjacent
Balyduff/Ballylemon scheme are putting this service area at risk. Similarly, the
three sources serving Kilmacthomas town are increasing in Nitrate levels and are
likely to cause supply difficulties in the near future. There is no readily available
back up in all of these cases without rationalisation of supply network and sources.
Slow sand filtration plants incapable of removing colour in excess of the 20 Hazen
limit in the EU Drinking Water Directive. Examples of this are the L.C.B.,
Ring/Helvick, Kill/Bonmahon and Tallow water supplies. Customer complaints
are quite numerous regarding excessive colour especially after storms and high
rainfall levels.
General lack of capacity whether source, mains or storage, which is impinging
adversely on economic and housing development. Most urban areas within the
county have come under severe pressure to service development land for housing.
Considerable development pressure exists in many settlement areas throughout the
county with numerous planning applications for multiple unit housing
developments currently under consideration. A quantified review of the current
development pressure is included in section 4 of this report. . At present
Dungarvan does not have adequate storage capacity to service its current demand.
Towns such as Lismore, Cappoquin and Tallow all have marginal water supplies
which must be urgently improved and extended to provide the necessary
infrastructure for additional housing at these locations. A similar case can be made
for villages such as Ring/Helvick, Ballinroad, Ballyduff, Kilmacthomas and
Portlaw where population growth is dependant on services being available for
zoned land.
Apart from the East Waterford Scheme, there are no other Regional Water
Supplies in the county. Major rationalisation and regionalisation of the entire
4

______________________________________________________________________________________
system is therefore a critical and urgent necessity. Increasingly stringent standards
regarding quality and service can only be achieved by modern treatment methods
in schemes that are properly resourced and maintained and of a size, which can
produce high quality water in a cost effective manner.
The main problems associated with individual schemes are:
Dungarvan - Inadequate storage. Vulnerability of Source. Increasing Nitrates.
Lismore/Capoquin/Ballyduff – Slow sand filtration, high colour, overtaxed
capacity, taste and odour problems. This interconnected scheme has two
boreholes serving Cappoquin and its hinterland which are deemed high risk to
pollution and have had results exceeding the MAC for nitrates.
Tallow & Portlaw - Supply shortages during summer period. Inadequate and
vulnerable source capacity and pipe network. No margin for new development – a
major constraint to meeting the significant demand for serviced housing land
especially in Portlaw.
Kilmacthomas – inadequate sources and storage capacity. No margin for new
development.
Bonmahon/Annestown - Lack of mains and storage capacity. Source vulnerable
to pollution.
Ring/Helvick – Suffers from inadequate and vulnerable sources inadequate
treatment and lack of capacity during the summer where there is a large increase in
population due to summer gaeltacht schools and tourism.
Dunmore East– Insufficient service storage capacity and inability to cater for peak
tourism demand.
Faithlegg/Passage/Cheekpoint – Lack of source, storage and mains capacity
Deelish/Ballinacourty (including Ballinroad – Water quality deficiencies, lack of
capacity and severe development pressure.
Many of the smaller settlement zones are experience severe development pressure
with limited current capacity.
It is clear that immediate substantial investment is required if water supplies in County
Waterford are to be rationalised and modernised to a standard which embodies current
practice and requirements and which will allow the increasing pressure for
infrastructure capable of serving housing, tourism and industrial demand to be
adequately met.
In 2003 Waterford County Council approved the Rural Water Strategic Plan. The
focus of the plan was the existing critical water supply-demand balance, the need to
meet the projected demand and the provision of satisfactory levels of service over the
20-year period from 2001-2021. This required that adequate water resources and
associated treatment capacities would be available to cater for projected demands, that
the water supply system infrastructure would be adapted to the supply requirements
and that the appropriate operating practices would be put in place to maintain
capability.

______________________________________________________________________________________
A huge increase in new development since 2003 has accentuated the supply problems
throughout the County, with demand far exceeding supply almost everywhere.
To meet these strategic objectives and deal with the supply shortages it is proposed in
the short term to rationalise water supply within the county by amalgamating and
upgrading adjacent smaller schemes into more viable and manageable larger schemes
with a short-term goal of regionalising supplies particularly in the west and mid county
areas.
Waterford County Council is progressing a number of strategic actions in order to
deliver on the strategic plan:
Water Conservation and Mains Leakage Control
Mains Rehabilitation
Capital Investment and Scheme Rationalisation
Demand Management
Leakage Control & Demand Management
Demand management measures are necessary to ensure the sustainable use of drinking
water resources and to provide an adequate level of service to all customers.
Water conservation and leakage control will continue to be an important aspect of the
management of our water distribution system. Bursts resulting from pipe
deterioration, excavation works, ground movements, abnormal loading will continue.
However, as a result of the investment in district metering and telemetry, these
potential bursts can be identified and speedily repaired ensuring security of supply to
our customers. A € 2.6 M countywide water conservation programme is currently
progressing with 3 leak detection teams currently in operation.
Proposals for substantial mains replacement under Phase 3 of the Water Conservation
Project are currently in preparation and will be required to achieve target leakage levels.
Waterford is working towards progressively reducing levels of unaccounted for water
to economic levels as determined in detailed studies undertaken as part of the Water
Conservation Project. Target economic levels of leakage throughout the county have
been established with a 10 year glide path to reach and maintain target levels. The
necessary water conservation measures to achieve an economical level of leakage
includes the installation of monitoring equipment and dedicated personnel to improve
leakage assessment capability and to establish a strategy of repair, rehabilitation or
replacement.
Bulk Metering
Bulk metering exists on the majority of Waterford‟s water supply schemes including
the largest 14 schemes representing 95% of the water consumed in the county which
now have established district metering areas following implementation of the Water
Conservation Project.
6
Waterford County Council Water Services Investment Programme Assessment of Needs 2007-2009
______________________________________________________________________________________
In the principal towns of Dungarvan and Tramore systems of metering, zoning and
logging are in place to quantify and help locate system losses. The telemetry systems in
Dungarvan and Tramore are in operation for a number of years and were rationalized
under the Waterford County Water Conservation Scheme in late 2005. Both systems
have zoned out the supply system into manageable area sizes. While these are initially
costly installations it is felt they are the most appropriate and cost effective long-term
measures to manage the distribution systems. The provision of permanent logging and
telemetry on the remaining larger schemes is currently under review and it is proposed
that some level of telemetry will be installed as part of the Water Conservation Project.
On the detection and repair side the council have three teams of leakage detection
inspectors, and have added to the number of plumbers employed to maintain the pipe
networks to achieve and maintain an economic levels of leakage throughout the
county.
Customer Metering
In total there are approximately 2,700 non domestic water service connections located
within the distribution system of which 2,000 are metered and an additional 700 water
service customers currently paying fixed charges. Waterford County Council is
currently engaged in a non domestic metering project to meter all non-domestic
consumers in accordance with government water pricing policy. A database of all non-
domestic customers and existing meter stock is currently being prepared.
Connections
A preliminary study indicates that there are approximately 17,000 connections to the
public water supplies in County Waterford.
In addition to these connections, public water is also supplied to 13 number private
group water supply schemes.
Water is exported from the East Waterford Regional Water Supply Scheme to
Waterford City. The exports from the East Waterford Regional WSS are metered and
are treated as bulk exports.
Rehabilitation
The majority of the smaller schemes in Waterford County cannot sustain leakage and
are a huge drain on resources as a single leak of 10 l/min can equal the normal output
of a small scheme. The recurrence of leaks on pipe sections in some cases leads to
pipe replacement as the only feasible remedy to sustain the schemes. Larger schemes
i.e. Towns and Villages can sustain more leakage without loss of service. Leakage on
larger schemes is comprised of breakages (large losses) and accumulated minor
leakages due to age of the networks. Again specific sections of distribution pipework
need replacement to make the system sustainable.

______________________________________________________________________________________
Well in excess of 50% of the council‟s supply networks are over 30 years old. Plastic
piping of 25 to 30 years is included in this figure and is a most significant problem with
respect to leakage.
A large proportion of our plastic (polythene/polyethylene) pipe has deteriorated to a
state where leaks are occurring by structural failure of the pipe walls. A detailed
countywide assessment and justification for pipe rehabilitation or replacement has
been undertaken as part of the Waterford County Water Conservation Project and a
„Rehabilitation Needs Assessment Report‟ has been prepared. The Report includes a
priority mains replacement programme recommending approximately 70 km of mains
replacement per year over the next 6 years at a total cost estimate of €14M per annum.
Capital Investment
The DEHLG Capital Investment Programme 2005-2007 identifies a range of schemes
at the planning, design/construction stage. In the case of Waterford County Council
€167,587 million of capital investment has been identified, of which €52.5 million
relates to improvements to water supply schemes and the remainder relates to
wastewater schemes. In addition, Waterford County Council will have received €2.6
million in funding towards the water conservation scheme for the initial study phase.

2.2 Wastewater
At present four strategic action lines are being pursued in parallel, to ensure the
drainage and treatment systems provided by Waterford County Council meet the needs
of its customers. The strategic action lines can be summarised as follows:
Provision of New Sewers, Pumping Stations and Wastewater Treatment Plants.
Rehabilitation and enhancement of Small Rural Treatment Plants
Preparation of New Integrated Policies
River Basin Catchment approach for Integrated Management of Water
New Sewers, Pumping Stations and Treatment Plants
There is currently a large infrastructure deficit with regard to foul sewerage collection
and treatment within County Waterford. In order to rectify this situation and to
comply with the relevant EU Regulations a number of substantial sewerage schemes
are now at various stages of stages of planning, design or construction. Dungarvan
Sewerage Scheme consisting of separate contracts for collection system, pumping
stations and wastewater treatment plant with sea outfall at a current estimated out-turn
cost of € 38,650,000 is nearing completion. Construction on the collection system was
substantially complete in October 2005 and commissioning of the treatment plant
contract has commenced.
Tramore Sewerage Scheme which consists of a new pumping station and a state of the
art wastewater treatment plant including a new 2km long marine outfall at a cost
estimate of € 20,900,000 is also well advanced with civil works nearing completion.
Preliminary proposals have been developed and costed for upgrading and extending
the combined sewer networks to partially combined sewer networks and the provision
of wastewater treatment plants for the towns of Ardmore, Cappoquin, Kilmacthomas,
Tallow, Stradbally, Ballyduff/Kilmeaden and Dunmore East. (7 Grouped Villages
Scheme) at a total estimated cost of €46,214,000. The proposals include for the
provision of new storm sewer networks to facilitate diversion of road drainage from
the existing combined sewers to the proposed storm sewer networks so as to reduce
hydraulic loading on the proposed wastewater treatment plants. Proposals for new
pumping stations are included in the scheme proposals for Ardmore, Stradbally,
Cappoquin, Kilmacthomas, Ballyduff/Kilmeaden and Dunmore East. A value
engineering process has been conducted with the DOEHLG and Contract
Document‟s are currently at draft stage.
Rehabilitation and Enhancement of Small Rural Treatment Plants
Waterford County Council is currently responsible for seventy-eight Sewerage
Schemes. These vary in size from major networks serving Dungarvan and Tramore to
small schemes serving groups of Local Authority houses consisting of simple septic
tank systems and percolation areas or direct discharge to inland and coastal waters.
Many of the towns and villages within the County are located either on the coast or on
major rivers. In the past these formed a convenient means of effluent disposal with
9

reliance placed on dilution and assimilative capacity to deal with pollution problems.
The enactment of various EU Directives now place serious demands on this Council
to address the deficiencies in the existing systems. To this end, Waterford County
Council has advanced preliminary proposals to develop wastewater treatment plants
providing secondary treatment to the towns of Ardmore, Cappoquin, Kilmacthomas,
Tallow, Stradbally, Ballyduff/Kilmeaden and Dunmore East (7 Grouped Villages), and
Cheekpoint. In addition contracts have recently been awarded for new wastewater
treatment plant construction for the towns of Clashmore, Aglish, and Villierstown on
which construction has commenced. The Piltown Wastewater Treatment Plant
construction is nearing completion.
Integrated Policies
Most of the larger towns in County Waterford are served by “combined drainage
systems” (storm water and foul drainage share the same pipe).
Discharge from these combined systems is generally via septic tank to rivers or directly
to sea with reliance being placed on dilution and assimilative capacity to deal with
pollution problems. With the advent of EU Directives this approach is no longer
appropriate. With the introduction of wastewater treatment plants the high flows
associated with combined drainage systems during storm conditions become
unsustainable. Addressing these problems will involve some civil works, such as the
preparation of Drainage Area Plans involving new storm drainage systems. The old
model, whereby storm water was conveyed as quickly as possible to a pipeline, which
was sized to convey peak storm flows to the nearest watercourse may not be
sufficiently robust in all situations to deal with the type and climate change conditions
which have prevailed in recent years and increasing levels of development.
Waterford County Council has adopted the principles of Sustainable Urban Drainage
Systems (SUDS) for all new development where appropriate and economically viable.
These principles include the attenuation of storm water at source or the provision of
compensation storage to minimise large storm water flows.
Catchment Based Approach
The implementation of the Water Framework Directive is being carried out on a
catchment basis and Waterford County Council is participating in both the South
Eastern River Basin District Project (lead authority Carlow County Council) and the
South Western River Basin District Project (lead authority Cork County Council).
These are four-year projects to develop a management infrastructure and measures,
which will endeavour to provide good quality water in the river systems of the South
Eastern and South Western River Basin Districts by 2013. The preparation of new
catchment based management systems will involve extensive public consultation and
will address issues giving rise to deterioration in river quality.
The pollution control measures used in County Waterford are summarised in this
section. Measures include the following;
10

3.0 ACHIEVEMENTS TO DATE (2004-2006)
The following summarises the achievements in the provision of improved water
services and water management practices in Waterford County Council over the last
three years.
3.1 Water Supply
East Waterford Water Supply - Stage 2, Phase 1
The East Waterford Water Supply Scheme, Phase 1 at a cost of €12.9m is now
substantially complete. Final accounts for Contracts 4, 8, 19A and 19B are agreed by
the DOEHLG. Final Accounts for Contracts 9 and 10 are currently with the
DOEHLG for approval. The scheme involved upgrading the trunk distribution
capacity to both Waterford City and the east of the county including Tramore and
Dunmore East, as well as providing much increased Reservoir capacity at each
location. An 8,500m³ Reservoir was completed at Kilcaragh serving the south east city
area and the Dunmore Region and a 10,000m³ reservoir was completed at Ballydrislane
to serve the Tramore area.
Phase 1 of the East Waterford Water Supply Scheme also included interim upgrading
at Adamstown Treatment Works. The works consisted of four number additional
upward flow sedimentation tanks at a cost of €0.64m.
The last remaining contract in Phase 1 involved the construction of an 8,500m³
Reservoir at Kilcaragh, as well as construction of an improved distribution system in
the South East City area and the contiguous county area including a connection to
Foiloun Reservoir. This contract is now complete.
East Waterford Water Supply - Stage 2, Phase 2
The East Waterford Water Supply Scheme – Phase 2 involves harnessing the River
Mahon at Seaview, upriver from Bonmahon, to augment the existing source supply
capacity. From the proposed intake on the River Mahon, supply will be pumped to
Ballyshonock Dam via a 600 mm dia rising main. A new 700mm dia trunk main will
supply Adamstown from Ballyshonock Dam. Phase 2 also includes for almost
doubling the treatment capacity at Adamstown.
Phase 2 is divided into 5 separate contracts:
Contract 2 - Extension to Adamstown, Civil Works.
Contract 3 - Extension to Adamstown, Mechanical & Electrical Works.
Contract 11 - Mahon Intake, Pumping Station & 600mm rising main to
Ballyshonnock, Civil Works.
Contract 12 - Mechanical & Electrical Works for Contract 11
Contract 13 - 700 mm Trunk Main, Ballyshonock to Adamstown
Contract 13 commenced in September 2004 and a certificate of substantial completion
was issued in October 2005. Work on Contract 11 commenced in September 2005 and
is currently ongoing. Contract 12 was signed with the Contractor in September 2005.
12
Waterford County Council Water Services Investment Programme Assessment of Needs 2007-2009
______________________________________________________________________________________
Work commenced on Contract 2 in August 2006 following contract signing in May of
that year. A Report on Tenders for Contract 13 was issued to the DOEHLG in May
2006 with further clarification in June 2006. Approval has been received from the
DoEHLG. On completion of Phase 2 the capacity of the East Waterford Water
Supply Scheme will increase from a current production of 29,000 m³/d to a future
capacity of 52,000 m³/d.
Ring/Helvick Water Supply Scheme
The Ring/Helvick Water Supply Scheme Preliminary Report was submitted to the
Department of Environment, Heritage & Local Government in August 2003 for
approval. Proposals consist of developing a new groundwater source, with
chlorination and fluoridation to supply a future demand of 825m³/d, providing a 24
hours high level storage Reservoir at peak future demand and upgrade of the
distribution system. A suitable adequate water supply source has not been located to
date. Additional groundwater resources for the area are being progressed in parallel
with consideration of options to supply the area from the neighbouring schemes of
Dungarvan and Ardmore. The Ring/Helvick Water Supply Scheme is included in the
Government‟s Water Services Investment Programme to proceed to construction in
2007.
Deelish/Ballinacourty Water Supply Scheme
The Deelish/Ballinacourty Water Supply Scheme Preliminary Report was submitted to
the Department of the Environment in September 2003 for approval. The proposals
consist of developing a new groundwater source with chlorination and fluoridation, to
supply a future demand of 2,000m³/d, adjacent high level storage and extensive mains
replacement and upgrade. A geophysical survey for production borehole location was
completed in October 2003 and exploratory well drilling was conducted in the summer
of 2004. A suitable adequate water supply source has not been located to date.
Additional groundwater resources for the area are being progressed. The
Deelish/Ballinacourty Water Supply Scheme is included in the Government‟s Water
Services Investment Programme to proceed to construction in 2007.
Ardmore Water Supply Scheme
Following DoEHLG approval of the design brief for the Ardmore Water Supply
Scheme, Consulting Engineers were selected in January 2004 to prepare a Preliminary
Report setting out proposals for the augmentation and improvement of the Scheme. A
Draft Preliminary Report was submitted March 2005. Additional exploratory drilling
was carried out in June and September of 2005. A revised Preliminary Report was
submitted to WCC in May 2006. Following review and comments by WCC, the revised
PR will be submitted to the DoEHLG for approval. The Scheme is included in the
Department‟s Water Services Investment Programme 2005-2007 to commence in
2007.
Faithlegg Water Supply Scheme
The Faithlegg Water Supply Scheme Preliminary Report was submitted to Waterford
County Council in December 2006 and is currently under review. Following review
and comments by WCC, the revised PR will be submitted to the DoEHLG for
approval. The Faithlegg Water Supply Scheme is identified as the area supplied from
the Foilaun Reservoir which stretches from the northern edge of Dunmore East in the
13

______________________________________________________________________________________
south and Cheekpoint in the north and includes the zoned lands at Faithlegg, Passage
East, Crooke and Dunmore East. The Scheme is included in the Department‟s Water
Services Investment Programme 2005-2007 to advance through planning.
Dunmore East Water Supply Scheme
Consulting Engineers were selected in January 2004 to prepare a Preliminary Report
setting out proposals for upgrading Dunmore East Water Supply Scheme. Revised
Preliminary Report was forwarded to the DOEHLG in August 2006 for approval.
The scheme is included in the Department‟s Water Services Investment Programme
2005-2007 to start in 2006.
West Waterford Water Supply Scheme & Strategic Review
Consulting Engineers have been appointed to prepare:-
A Strategic Review of water supplies in West Waterford
A Preliminary Report setting out proposals for new water supply infrastructure in the
Stage 1 area.
The Strategic Review will identify possible water supply sources in the West Waterford
Area to resolve current source capacity and quality problems.
The Preliminary Report will concentrate on resolving current supply difficulties in the
Stage 1 Area, comprising Lismore, Cappoquin, Ballyduff and Tallow areas. Trial
drilling for water sources commenced in September 2005. Well drilling is complete.
The Project is included in the DoEHLG Water Services Investment Programme, 2005-
2007 with a start date in 2007.
Waterford County Council regards the development of a major Regional Water
Supply Scheme for the west of the county as its most important water supply
strategic objective. The current West Waterford Water Supply Scheme &
Strategic Study in the stage 1 area are considered to be interim steps towards
realising the counties overall strategic objectives.
Dungarvan Water Supply Scheme
Proposals are in place to provide additional high-level storage, rising mains and supply
mains to connect to the existing distribution system for the Dungarvan Water Supply
Scheme. A yield test was carried out on the Ballynamuck source as part of the trial
drilling for the West Waterford Strategic Review. The yield estimate of the well field
(approx 8,200 m3/d) is not as high as previously reported. Tenders have been sought
for additional drilling. Drilling contractor due to commence in early 2007. A Brief has
been prepared for the appointment of a Consulting Engineer to prepare a preliminary
report for the Dungarvan Water Supply Scheme. The scheme is included in the Water
Services Investment Programme 2005 – 2007 with a start date in 2007.
The previously unrealised limitations on the output from the Ballinamuck source, allied
to the unprecedented level of development in Dungarvan town and hinterland
underline the urgency of developing a Regional Supply capacity to augment
Ballinamuck and enable the county town to develop in a planned and sustainable
manner.

3.2 Wastewater Treatment
Dungarvan & Environs Sewerage Scheme
The Dungarvan & Environs Sewerage Scheme consists of two elements, the Collection
System and the Wastewater Treatment Plant at a combined current out-turn estimate
cost of € 38.65M. The collection system contract commenced in April 2003 and a
certificate of substantial completion was issued in September 2005. The
mechanical/electrical contract for pumping stations on the collection network is
ongoing. The wastewater treatment contract commenced in April 2004. Civil and
Mechanical/Electrical works are substantially advanced and commissioning of the
plant has commenced.
Sludge Management Plan
A Sludge Management Plan outlining County Waterford‟s strategy for managing
sludges produced from water and wastewater treatment has been prepared. The
strategy envisages sludges from the various wastewater treatment plants being collected
and dewatered at two satellite centres, one in the east of the county and one in the
west. Dewatered sludges will be transported to a central hub treatment facility, where
the end product bio-solids produced will be suitable for sustainable reuse in
agriculture. The Plan has been submitted to the DOEHLG.
Tramore Sewerage Scheme
The Tramore Sewerage Scheme at a cost of €20.9 M involves the transfer of collected
sewage via a new pumping station at the Promenade to a proposed wastewater
treatment plant located at Corbally Upper. The scheme also provides for
improvement to the existing Cove Pumphouse and a 2km long sea outfall to convey
treated effluent well out into Tramore Bay. The scheme consists of three separate
contracts, namely the Collection System Civil Works Contract, the Collection System
Mechanical & Electrical Contract and the Wastewater Treatment Plant. A certificate of
substantial completion for collection system civil works was issued in October 2005.
The Mechanical/Electrical works on the collection system are substantially advanced.
The wastewater treatment plant contract was awarded in November 2005. To date the
civil works element is 90% complete and the Mechanical/Electrical element has
commenced.
Tramore Sewerage Scheme – Collection System, Stage 2
A brief for the Tramore Sewerage Scheme – Collection System, Stage 2 was approved
by the DoEHLG in October 2005. The brief identifies the recent increase in
population in Tramore reducing the pipe capacity reserves, high levels of infiltration of
surface water into the existing system and existing overflows discharging into the
marine environment. Following fee proposal approval from the DoEHLG in October
2006, consultants have been appointed to prepare a Preliminary Report. The scheme is
included to advance through planning in the Water Services Investment Programme
2005 - 2007.
Seven Villages Sewerage Scheme
A revised Preliminary Report for the Seven Villages Sewerage Scheme at a total capital
cost estimate of €46.2M was submitted for DoEHLG approval in December 2003.
The proposals include for the provision of wastewater treatment and collection system
17
Waterford County Council Water Services Investment Programme Assessment of Needs 2007-2009
______________________________________________________________________________________
upgrade for the villages of Ardmore, Cappoquin, Kilmacthomas, Tallow, Stradbally,
Ballyduff/Kilmeaden and Dunmore East. It is proposed that the seven wastewater
treatment plants be let as a single Design Build and Operate (DBO) Contract with an
operation phase of 20 years. The collection system upgrade at each location involves
the provision of new storm water networks to facilitate the transfer of surface water
connections from the existing combined system to the new storm system. All future
foul and surface water connections to the networks will be to the partially combined
system and the storm system respectively to minimise storm flow to the proposed
treatment works.
The Part 8 Planning procedure has now been approved for all villages. A Judicial
Review of the Part 8 process in respect of Ardmore Wastewater Treatment Plant is
being sought by the landowners. A Value Engineering process was conducted with the
DOEHLG for all villages. Compulsory Purchase for relevant sites commenced in
February 2006. CPO‟s have been confirmed for Cappoquin, Dunmore East and
Stradbally. Applications for Foreshore Licences to the Dept. of Marine dated April
2005, are currently awaiting grant of licences. Additional Part 8 applications for
wastewater treatment plants at Ardmore and Ballyduff/Kilmeaden commenced in July
2006 and were approved by Council members in September 2006. Seven tenders were
received for Tallow collection system in December 2006.
The Waterford Grouped Towns & Villages Sewerage Scheme is included in the Water
Services Investment Programme 2005 – 2007 with a start date in 2007.
Cheekpoint Sewerage Scheme
The scheme includes a new wastewater treatment plant, collection system and sea
outfall for the village. A revised Draft Foreshore Licence was received from DCMNR
and is currently under review. The scheme has been included in the Rural Towns &
Villages Initiative in the Government‟s Water Services Investment Programme 2005 -
2007.
Bonmahon Sewerage Scheme
Proposals to provide appropriate secondary treatment to replace the existing septic
tank prior to discharge to Mahon River Estuary. Following approval of Fee Proposal/
Planning stage budget by the DoEHLG in August 2005 a Consultant was appointed in
September 2006. The scheme is approved to advance through planning in the Water
Services Investment Programme 2005-2007.
Ballyduff (Upper) Sewerage Scheme
Proposals to provide appropriate secondary treatment to replace existing septic tank
prior to discharge to the Blackwater River and a collection system upgrade. A revised
Preliminary Report was received from the Consultant‟s in July 2006 and is currently
under review. The scheme is included in the Water Services Investment Programme
2005-2007 with a start date in 2007.
Aglish, Piltown, Clashmore and Villierstown Sewerage
The report on Tenders for the Aglish, Clashmore and Villierstown Wastewater
Treatment Plant Contracts was approved by the DoEHLG in March 2006 with

4.0 WATER SERVICES NEEDS IDENTIFICATION
4.1 Introduction
In recent years there has been a very noticeable increase in development, particularly
housing development throughout County Waterford. Recent planning applications
suggest that this trend is set to continue as can been seen in the summary population
estimates table 4.2 in the following section. At the present time numerous water
supplies are approaching a critical supply demand balance as a result of increasing
demand. A similar water services deficit is experienced for wastewater collection and
treatment. It is deemed prudent therefore to review each area of zoned land identified
in the „Waterford County Development Plan 2005-2011‟ and the various local area
plans to quantify the water services needs at the present time and into the future. The
adequacy of the existing water services can then be assessed against the identified
existing and future water services needs.
The „Waterford County Development Plan 2005-2011‟ identifies a settlement strategy
for the county based on a settlement hierarchy reflecting the role of each settlement
type. It is noted in the Development plan that the settlement strategy was hindered by
infrastructural deficiencies in water and sewerage. The settlement hierarchy is based on
establishing a Primary and a Secondary Service Centre, District Service Centres (11
no.), Local Service Centres (18 no.) and Settlement Nodes (20 no.) The established
settlement hierarchy and the existing water, wastewater and storm water services are
summarised in Table 4.1 below.

______________________________________________________________________________________
Objectives
1. To provide or augment treatment capacity
2. To provide or augment collection pumping capacity
3. To reduce or eliminate storm water overflows
The examination of public water supply, wastewater treatment and drainage schemes
against the above criteria is carried out in Table 1 and Table 2 of Appendix 1 of this
report.
General Approach to Meeting the Needs
It is the intention of Waterford County Council to advance to construction the
schemes listed in the needs assessment through a number of mechanisms:
a) Direct Exchequer funding through the Department of Environment, Heritage
and Local Government.
b) Part financing through the Rural Water Programme (DoEHLG) in
combination with locally generated revenue from the Council‟s development
levy scheme, and
c) The Serviced Land Initiative (Circular L1/00 & L1/07) in combination with
Development contributions to Waterford Local Authorities.
In procuring the necessary schemes and/or infrastructure projects, Waterford County
Council will consider traditional procurement methods as well as:
Design and build procurement
Design, build and operate procurement as appropriate
Forms of public private partnerships
The decision on which form of procurement to pursue will be fully contingent on what
Waterford County Council considers the best Value for Money option in any
circumstance.
23
Waterford County Council Water Services Investment Programme Assessment of Needs 2007-2009
______________________________________________________________________________________
4.3 Basis of Needs Identification Quantification
4.3.1 Water Supply
A current water supply demand per person of 139 l/day is assumed based on the
„Waterford County Water Conservation Project‟ figures and „The National Water
Study‟ (NWS) prepared in 2000. Future demand figures are based on the estimated
water per capita consumption (Table 11 NWS) which identifies steady increase in per
capita demand to 157.5 l/s by 2032. The occupancy rate per dwelling is expected to
decrease over the coming years. Based on NWS figures the occupancy rate is assumed
to reduce from a current rate of 3 persons / house to 2.52 persons per house in 2032
in our future population estimates.
In the absence of detailed CSO Census 2006 figures for local areas the population
served for each development zone and within each supply scheme is calculated from
the An Post Geodirectory July 06 Building Count assuming an existing population
density of 3 per house. For the purpose of future water services needs assessment we
have assumed that all current planning applications will be developed in the period
2007-2009 with an average population density of 3 persons per house. In addition
commercial development is assumed to increase in line with residential demand in all
but the primary and secondary service centres where increased commercial and
industrial activity is expected.
From the summary Table 4.2 below it will be noted that the full development of all
residential land suggests an increase in population of 96 % or 43,723 persons within
zoned land over the design period to 2034. This compares with the CSO Population &
Labour Force Projections 2006 -2036 which estimates a national population increase
of 39% to the year 2036 based on the most optimistic population variant. The CSO
Census 2006 population statistic identified the population increase in County
Waterford over the inter census period was 9.2% marginally above the national average
of 8.1%. It is unlikely therefore that population increase in County Waterford will
exceed the CSO projections by any significant amount over the design period. In order
to reconcile the significant difference between population trends and full development
of available zoned land we have assumed design demand figures for each settlement
zone based on a percentage of peak development over a typical design period of 25
years from the end of 2009. It is intended that the level of water service provision
proposed will be sufficient as to not hinder future development within this timeframe.
In order to assess the potential peak future water services demand for specific
development areas for a 25 year design period from 2009 to 2034 we have assumed a
percentage of full development of all commercial, industrial and tourism zoned land
within the design timeframe in line with assumptions in relation to population above.
Residential development assumes a housing density of 8 houses per acre and an
occupancy rate of 2.52 persons per house based on figures from the „National Water
Study‟ to the year 2032. The full development of commercial/industrial zoned land
assumes a water services demand of 28m3/ha/day based on estimate figures from
existing water services preliminary reports for Waterford County Council. A summary
of the future demand estimates is summarised in Table 4.3 below.
24
Waterford County Council Water Services Investment Programme Assessment of Needs 2007-2009
______________________________________________________________________________________
Prioritization of a programme of works assumes that all current planning applications
whether approved or pending will be developed during the period 2007-2009 and that
the design demand figures for each development area will be realised over the design
period of 25 years from 2009. On this basis we have assumed a pro-rata demand
increase over the period 2010-2014 to identify all possible shortfalls in water services
provision. A summary calculation of the required water services needs at each
development area for the period up to 2009, from 2010-2014 and the design demand
for the 25 year period up to 2034 is included in Table 4.3 and in the following sections.
The available water services are compared to the estimated future water service needs
to identify and prioritize a programme of works over the next planning period.
Assessment of water supply requirements assumes proven source capacity and 24
hours storage for the design demand is required. If a source or storage capacity
shortfall is identified for the assessment period 2007-2009 or 2010-2014 then the
provision of additional water services is included in the prioritized programme of
works. The supply network capacity is generally insufficient to provide the required fire
flows outside of the larger urban areas. The requirement for increased mains capacity
for fire flows includes most water supply schemes in the county and it is therefore
considered impracticable to include on a prioritized works list. Where a supply
network capacity shortfall is identified for supply purposes this is identified in the
prioritized programme of works. It is intended that the necessary replacement of
numerous lengths of watermains deemed to be past their useful life will be catered for
under the next phase of the Water Conservation Project and therefore not included in
the programme of works.
4.3.2 Sewerage Schemes
While many of the public sewerage schemes in Waterford County fall under the
secondary treatment threshold of less than 2000 p.e. as defined in the Urban
Wastewater Treatment Regulations, it is recommended that a high standard of effluent
treatment should be provided for the protection of health and the environment,
particularly in relation to fish life in the receiving waters, and in anticipation of higher
treatment standards being required under the River Basin District Management
measures and by the EU in the future. It is proposed to adopt the following broad
design values for all small schemes considered in this report except where there is
adequate dilution to allow primary treatment only.
Treated Effluent
BOD – maximum 25 mg/litre 0s
Suspended Solids – maximum 35 mg/litre
COD – maximum 125 mg/litre
Effect on Receiving Waters
Maximum downstream increase in BOD of 1 mg/litre
Sludge Treatment
Provision of Sludge Holding tanks at each site with suitable facilities to permit
collection and transportation to sludge satellite and hub centres.
25
Waterford County Council Water Services Investment Programme Assessment of Needs 2007-2009
______________________________________________________________________________________
Many sewerage schemes in County Waterford have predominantly combined
collection systems and high surface water infiltration and because of this many plants
have become hydraulically overloaded. Investment in secondary treatment should be
carried out in conjunction with the removal of surface water from sewer networks.
In this report the existing public sewerage schemes serving settlement zones in County
Waterford were assessed as to their ability to cope with existing and future loadings
and a list of proposals have been developed. The design populations to be served are
as outlined in Table 4.2 above. The sewerage schemes which are currently included
with start dates or at construction stage in the Water Services Investment Programme
2005-2007 are:
Dungarvan Sewerage Scheme
Tramore Sewerage Scheme
Waterford Grouped Towns & Villages SS - Ardmore, Tallow, Stradbally, Cappoquin,
Dunmore East, Kilmacthomas,
Ballyduff/Kilmeaden
Ballyduff Upper Sewerage Scheme
Aglish Sewerage Scheme
Clashmore Sewerage Scheme
Villierstown Sewerage Scheme
Piltown Sewerage Scheme
Cheekpoint Sewerage Scheme
Due to the long lead in period for scheme implementation and the recent huge
increase in residential and commercial development, the capacity of schemes at
construction stage have been reviewed with regard to current and future loading
estimates.
The capital cost estimates for treatment plant provision inclusive of VAT is taken from
tender costs on recent projects. For smaller schemes up to approximately 1000/pe
there is a wide selection of package plants available at very competitive rates ranging
from approx. €150,000 for a 150 p.e. plant or €1,000/pe to €450,000 for a 1000/pe
plant or €450/pe. For smaller schemes it should be noted that land acquisition costs
can represent a significant element of the overall costs over and above the unit
treatment cost. For larger sewage treatment installations where the plant is generally
more robust with less package elements and large civil works the costs tend to
increase. The cost estimate for treatment plants varying from 2,000/pe to 25,000/pe
are assumed to range from €1,000/pe to €450/pe based on recent tender prices and
estimates prepared for Waterford County Council.

4.4 Water Services Needs Assessment
4.4.1 Water Supply
4.4.1/1 Dungarvan Water Supply:
The primary source for the Dungarvan Water Supply Scheme is the Ballinamuck
Boreholes. These feed into the Dungarvan Water Tower TWL 47.58 mOD which
governs pressures throughout the town. There is an additional spring source at
Springmount connected directly to the supply network. Springmount is used primarily
in winter months to avail of night time electricity tariffs. Water from Dungarvan also
currently augments the neighbouring schemes at Ballyduff/Ballylemon and
Ballinacourty/Deelish including Ballinroad.
The existing capacity of the Ballinamuck borehole is estimated at 7,000 m³/d following
recent pump testing which is less than previous estimates. The limiting factor being
ingress of fines to the borehole. Springmount source capacity estimates at 1,200 m³/d
giving a current combined source capacity of 8,200 m³/d. Treatment for both sources
consists of chlorination and fluoridation. The Dungarvan water tower was built in
1965 and has a capacity of 1100m³.
In view of unprecedented levels of residential and commercial development in
Dungarvan and its surroundings in recent years a review of the current and future
demands was deemed appropriate to assess the adequacy of the existing scheme and
potential spare capacity to augment adjacent schemes. It is noted that proposals are
included in the Water Services Investment Programme 2005-2007 to provide for the
shortfall in storage capacity on the scheme (Est. Cost €3.47M) The existing and future
demand estimates on the scheme are as follows:
Table 4.4.1/1 Dungarvan Water Supply – Existing & Future Design Demand
Estimates
Domestic Non Domestic UFW Total
(m³/d) (m³/d) (m³/d) (m³/d)
2006 Existing 1475 1566 2517 5558
2009 2028 2150 2247 6425
2014 2221 2354 2255 6830
2034 3050 3233 2692 8975
It is clear that the existing source capacity is adequate over the strategic planning
period to 2014, beyond which additional service capacity will be required to meet
increasing demand both in the town and the region. A major increase arising from
industrial demand could shorten this time scale dramatically. Storage provision should
be at least 9000m³ to provide for 24 hours storage based on design demands.
27
Waterford County Council Water Services Investment Programme Assessment of Needs 2007-2009
______________________________________________________________________________________
The strategic review currently undertaken for West Waterford should identify potential
sources for the region, including Dungarvan. The development of a regional supply
capacity in West Waterford, which will, inter alia, augment Dungarvan Water Supply is
Waterford County Councils primary strategic water supply objective.
4.4.1/2 Faithlegg Water Supply Scheme (incl. Passage East, Crooke,
Cheekpoint, Woodstown and Killea)
The water supply from the Belle Lake reservoir extends from Cheekpoint to the north
and the outskirts of Dunmore East to the south and represents a separate supply area
within the Dunmore East Regional Water Supply. The supply area includes Faithlegg
and proposals for the Faithlegg Water Supply are included in the Water Services
Investment Programme 2005-2007 to advance through planning. The original source
for this supply area is Belle Lake. Water from the lake is treated locally in a dissolved
air floatation plant and filtered, augmented by activated carbon, disinfected and pH
corrected before being pumped to the adjacent 381m³ reservoir TWL 119.2 MOD at
Foilaun Hill. The reservoir at Foilaun Hill can also be supplied from the East
Waterford Water Supply Scheme (EWWSS) via Kilcaragh Hill reservoir. Water source
provision is considered secure from the latter. The Belle Lake abstraction order limits
abstraction to 506.4m3/d, whereas estimated future demand is 2,222m3/d. A new
source is therefore required to meet both existing and future demand.
The water storage for public schemes provided in the area is as follows:
318m³ (70,000 gals) Foilaun Regional Reservoir of TWL 119.2 mOD
182m³ (40,000 gals) Passage East service reservoir of TWL 57.64 mOD
45m³ (10,000 gals) Cheekpoint service reservoir of TWL 66.31 mOD
8,500m³ (1,870,000 gals) Kilcaragh Hill reservoir of TWL 83.00 mOD
A preliminary water audit of the supply area using standard methodology has identified
a demand of 808.4 m³/d going into supply with unaccounted water estimated to be
187.86 m³/d or 23.3%.
Population statistics for the three district electoral divisions (DEDs), namely Faithlegg,
Killae and Woodstown, which are primarily in the supply area, indicate a current
population of 2,492. In view of the proximity to Waterford City and the available
zoned land a population growth in the supply area of 151% is predicted (from 2,492 to
6,265 people). Taking into consideration the likely growth in all sectors and allowing
for a peak day factor, the design demand estimate for the scheme to the year 2031 is
2,322 m³/d.
A new source is required for existing and future demands. The storage capacity at
Foilaun and Cheekpoint is insufficient to cater for existing demand and there are
supply disruptions at peak demand periods due to lack of capacity in the distribution
system. It is proposed to replace the existing source at Belle Lake with water from the
East Waterford Water Supply Scheme via the Adamstown treatment plant and the
Kilcaragh Hill reservoir. Once the upgrading of the Adamstown treatment plant is
complete by end 2007, it will have sufficient capacity to supply the Faithlegg Water
Supply area to allow Belle Lake and its treatment plant to be withdrawn from service.
28

______________________________________________________________________________________
It is also proposed to no longer supply the northern part of the area from Foilaun
reservoir but to feed the area directly from Kilcaragh Hill reservoir. Watermains of
sufficient capacity are already installed between the Kilcaragh reservoir and Blenheim
Cross, therefore an additional length of pipework is required between Blenhiem Cross
and the Faithlegg area. A new storage reservoir at Cheekpoint is proposed with a
capacity of 470 m3 located on Faithlegg Hill with adequate elevation to provide
minimum 15m head at all locations. A booster pumping station will be required to
transfer water from the Kilcaragh reservoir to the proposed new reservoir on Faithlegg
Hill due the to relative elevations involved.
To improve water supply to the southern area of the Faithlegg Water Supply Area it is
proposed to construct an additional 1,200 m3 reservoir adjacent to the existing 318m3
Foilaun reservoir to be supplied directly from Kilcaragh reservoir via the existing
Hickey Crossroads pumping station. The existing pumps in the Hickey Crossroads
pumping station have sufficient capacity to cater for future demands. Cost estimates
for the above proposals are as follows:

4.4.1/3 Dunmore East Water Supply Scheme
The original Dunmore East Water Supply Scheme was constructed in the 1950‟s based
on abstraction from Belle Lake, 5 km northwest of the town. Due to growth in
demand in the supply area arising from population increase, the capacity of this source
was exceeded in the late 1970‟s. Consequently, a 250mm trunk main was laid along the
coast road between Tramore and Dunmore East to supply the latter with water from
Tramore. Following the commissioning of the East Waterford Supply treatment plant
in Adamstown in 1984, water from that plant was fed into Tramore and thence to
Dunmore East with all supply to the latter currently originating at the Adamstown
waterworks via the Sporthouse Reservoir (2,500 m3)
The current population of the village is 1,650 persons approximately. This almost
doubles in the peak holiday season due to the extensive holiday developments in the
village and the local hotels and B&B‟s. There is also a seasonal demand for water in the
29
Waterford County Council Water Services Investment Programme Assessment of Needs 2007-2009
______________________________________________________________________________________
port area of the village arising from ice making, fish processing and servicing of fishing
trawlers.
The scheme has difficulty in meeting the demand imposed on it, particularly in
summer season due to insufficient storage capacity, high unaccounted for water and
limited distribution system capacity to cater for peak tourism demand.
A preliminary water audit on the scheme assessed the existing demand as 749.81 m3/d
with unaccounted for water at 32.45%. In view of the proximity to Waterford City, the
desirable coastal location and tourism demand, the future demand to the year 2031 is
estimated as 3,000 m3/d plus a possible 515 m3/d for Waterford Airport and
immediate environs.
It is proposed to alter the source reservoir from Sporthouse to Ballydrislane (10,000
m3) with provision of booster pumping at Corbally Cross thereby permitting balanced
regional distribution of water supply and availing of the storage provision in
Ballydrislane reservoir. Local storage provision at Coxtown East consisting of a 1,870
m3 ground level reservoir and adjacent 430 m3 water tower is also proposed to provide
24 hrs storage provision to all of the Dunmore East distribution system including
localised areas of higher elevation. Upgrade of the distribution system it also proposed
to cater for future demand estimated and fire flows. Cost estimates for the above
proposals are as follows:
Quantity Rate Capital Cost

4.4.1/4 West Waterford Regional Water Supply Scheme
The West Waterford Water Supply Strategic Review and Stage 1 Improvements which
is included in the Water Services Investment Programme 2005-2007 is currently
assessing source availability in the region. It is envisaged that Stage 2 of the scheme
would involve advance planning and preparation of a Preliminary Report for the
development of a Regional Water supply in the west of the county, utilising the
information obtained in the Strategic Review. Stage 3 proposals include for
rationalising supply and rehabilitation of the existing schemes in the south west of the
county, including the existing schemes of Ballyduff/Ballylemon*, Colligan,
Kilgobinet/Inchindrisla*, Ballyguiry, Dungarvan*, LCB*, Clashmore*, Shanacoole*,
Villierstown, Aglish, Ticknock/Tinnabina*, Piltown, Grallagh*, Kereen*, Geoish,
Cooneen*, Ballycurrane and Tallow.

West Waterford Regional Water Supply Scheme
Stage 2 – Advance Planning & Preliminary Report
Lismore, Ballyduff and Cappoquin (LCB)
The LCB water supply scheme services the towns of Lismore, Ballyduff and
Cappoquin and the substantial hinterland in between. The scheme is made up of a
number of interconnected local sources and service storage. The primary source for
Lismore town and the hinterland to the west as far as Ballyduff is the Glenakeefe and
Owenashad streams. The Glenakeefe & Owenashad sources are treated at Monamon
and supply Lismore via a reservoir located at Ballygalane (TWL 100.88 mOD.) There is
also a local boosted supply from Monamon. A secondary borehole source at Deerpark
supplies directly to the network south of Lismore. Ballyduff Reservoir TWL 63.20
mOD services Ballyduff town and is supplied from Aglish Glencairn borehole with
augmentation from Lismore Reservoir as required. Cappoquin is serviced from
Cappoquin Reservoir TWL 70.02 mOD which is fed from the Monument borehole.
Closed valves separate Lismore from Cappoquin.
There is no test yield available for the combined Glenakeefe and Owenashad streams.
Current supply varies from 600-650 m³/d on average. Treatment consists of slow
sand filtration. The raw water quality was identified as category A2 in the Rural Water
Strategic Study therefore the treatment standard is inadequate for removal of periodic
colour. Upgrade or temporary closure of the treatment plant during periods of high
colour in the water is required.
The monument borehole in Cappoquin has a test yield of 687 m³/d and is identified as
medium risk of pollution in the Rural Water Strategic Study. High nitrates have been
recorded on the source.
The Aglish/Glencairn borehole supplying the Ballyduff Upper reservoir has not been
yield tested, however current average supply of 108 m³/d would appear to be its
capacity.
The Ballyhane borehole on the Ballyduff/Ballylemon/Ballyhane Water Supply adjacent
to Cappoquin has a test yield of 1,363 m³/d, however this source has been identified as
high risk and high nitrates have been recorded.
The Deerpark borehole to the south of Lismore supplies an average of 151 m³/d
directly to supply. This source has not been yield tested. It is expected that the
Deerpark source could supply well in excess of 150 m³/d, however the existing layout
of the network and the absence of storage at Deerpark limits the hours of pumping.
The existing sources on the scheme assuming import of water from Ballyhane would
appear in the region of 2000 m³/d but could be reduced to 1400 m³/d with poor water
quality at Glenakeefe and Owenashad rivers. The high risk status of larger source
boreholes also puts the supply at risk. Additional sources are required.
There are three local storage Reservoirs on the scheme namely Lismore Reservoir
TWL 97.93 mOD, Cap 590 m³ (1955), Ballyduff reservoirs TWL 63.2 mOD, Cap 136
m³ (1975) and Cappoquin Reservoir TWL 70.02 mOD, Cap 727 m³ (1975).
31
Waterford County Council Water Services Investment Programme Assessment of Needs 2007-2009
______________________________________________________________________________________
There is significant residential development pressure within the settlement zones of
Lismore, Cappoquin and Ballyduff. Commercial water supply demand is also expected
to increase in line with domestic demand within the settlement zones.

Sources are close to capacity and augmentation from adjacent source at Ballyhane is
limited by network layouts and lack of storage on the source. Upgrade proposals are
required as a priority in view of the potential shortfall to accommodate demand
estimates for 2009 and 2014.
The following upgrade works are required to meet the design demand requirements.
The slow sand filters treating the Glenakeefe and Owenashad rivers requires
refurbishment and automatic shut down during flood conditions with consequent
reduced raw water quality. Alternative sources are required to provide capacity for
future development and in the event of the temporary loss of the Glenakeefe and
Owenashad river sources. A preliminary cost estimate of € 2.0 M is included for
interim new source provision, additional storage capacity and upsizing of 7.0 km of
main connecting Cappoquin, Lismore and Ballyduff. Development of a major surface
water source such as the Blackwater is considered to be the most likely option for
ensuring supply security into the future for the region.
Tallow Water Supply Scheme
Tallow has a single water source, which is extracted from a stream at Knockaun and
treated by means of slow sand filters before gravitating to the Tallow Reservoir TWL
66.45 mO.D. The scheme is close to capacity and low pressures are currently
experienced on the extremities of the scheme resulting from lengths of poor quality
main, where severe encrustation of the cast iron pipework has been identified.
32
Waterford County Council Water Services Investment Programme Assessment of Needs 2007-2009
______________________________________________________________________________________
There is no test yield available for the source. The minimum yield of the stream source
is estimated at approximately 400 m³/d based on observation during the summer
months. Treatment consists of settlement tank followed by 3 no. slow sand filters each
10.4m x 3.7m with a design capacity of 370 m³/d assuming a peak filter rate of 0.2
m/h and one filter bed out of operation for maintenance. The stream source is
classified as high risk and prone to pollution from cattle grazing in the vicinity. The
slow sand filter treatment process is not suitable for the removal of colour which can
be problematic following heavy rainfall events.
The reservoir capacity is 273m³. The scheme construction dates back to the 1940s.
The area currently has 395 domestic connections and 70 non-domestic connections on
the Tallow WSS with an average metered flow from the reservoir over the last 12
months of 379 m³/d. A water audit undertaken as part of the Water Conservation
Project in late 2005 identified a distribution input of 430 m³/d which included 162
m³/d UFW. It is clear from these figures that the scheme is at capacity. There is
substantial zoned land within Tallow for future residential and industrial development.
It is expected that water demand will increase steadily with developments within these
zoned lands. Future demand estimates are as follows:
Table 4.4.1/4.2 Tallow Water Supply Scheme – Existing & Future Water
Demand
Domestic Non UFW Total
m³/d Domestic m³/d m³/d

2014 270 200 200 670
2034 429 448 376 1253
As can be seen there is an expected large increase in demand on the scheme which is
evident by current planning applications for 168 houses in Tallow. The existing
scheme capacity is inadequate to meet projected demand to 2009; therefore upgrade
works are a priority.
Additional source capacity to augment or replace the existing stream is required. A
source and treatment capacity of 1,250 m³/d is required. The West Waterford Water
Supply Scheme Strategic Review which is currently included in the Water Services
Investment Programme 2005-2007 will inform on possible alternative source options.
Existing storage capacity of 273 m³ is inadequate to provide security of supply for an
increasing demand. Provision of 1250 m³ storage representing 24 hrs at design
demand at an elevation of 65 mO.D. is required. The existing distribution network
contains a substantial length of 4” cast iron mains dating back to the 1940s including
the trunk main from the reservoir to the town which will require upgrading to
accommodate increased demand. Preliminary cost estimates of €2.0 includes for new
interim source development along with storage and upgrade of the distribution
network.

West Waterford Regional Water Supply Scheme
Stage 3 - Rationalisation of Existing Supplies
Clashmore & Environs
The Clashmore Water Supply Scheme is interconnected with adjacent schemes of
Shanacoole and Grallagh. Clashmore village is currently supplied from a borehole at
Ballinamultina to the north of town. A spring at Laurentum which also supplied
Clashmore to the south is now supplying the Shanacoole scheme with the Shanacoole
groundwater supply being discontinued due to water quality issues. Grallagh has a
separate ground water source at high elevation feeding direct to supply. The Grallagh
and Shanacoole schemes are separated by closed valve. The borehole serving
Clashmore supplied an average of 75m3/d over the last 12 months. The test yield of
this source is reported as 92 m3/d. The springs at Laurentum have not been yield
tested however previous assessments suggest a significant yield. A yield estimate of 600
m3/d is assumed for assessment purposes.
The only storage available on the three schemes is located north of Clashmore at
Ballinamultina with Capacity 90.9 m3 (20,000 gals).
Future demand assessment is based on residential development within the settlement
zones of Clashmore and Piltown. For the purpose of demand assessment it is assumed
that demand outside the settlement zones will remain static over the design period.

Ballyduff, Ballylemon Ballyhane
This water supply scheme services a large rural area between Dungarvan and
Cappoquin. The scheme can be divided into two discrete water supply areas. In the
eastern half, the source is at the Glenavaddan springs that feed the Glendog reservoir,
TWL 91.44 mO.D. This area is augmented by a supply from Dungarvan Tower, TWL
47.58 mO.D. The western half of the scheme is supplied from the Ballyhane borehole.
The western section of the scheme is separated by closed valve. A closed valve also
separates the scheme from the LCB scheme.
The average flows from the Glendog reservoir outlet meter for the last 12 months are
190 m³/d with a peak flow of 264 m³/d in November 2005. Water augmentation
from Dungarvan Tower average 82 m³/d with a peak of 136 m³/d in September 2005.
The Ballyhane borehole supplied an average of 379 m³/d with a peak of 494 m³/d in
March 2005. The source capacity of the Glenavadden springs is not capable of
meeting summer demand which necessitates augmentation from Dungarvan Tower
and a reduction in the area served from Glendog in the summer months. A test yield
for the Glenavadden springs source is not available however a yield estimate of 125
m³/d is assumed from observation. The Ballyhane borehole test yield is reported at
1363 m³/d. Nitrate levels in the Ballyhane borehole are high and the long term
viability of this source is in question. Treatment at all sources consists of chlorination
and fluoridation. The storage capacity is limited to the Glendog reservoir constructed
in the 1950‟s with a capacity of 113 m³.
There are currently 343 domestic and 99 non-domestic connections on the
Ballyduff/Ballylemon/Ballyhane water supply scheme with a peak demand of
approximately 650 m³/d including approximately 350 m³/d UFW. The only zoned
land currently served by the scheme is at Ballynameelagh. It is not expected that
demand on the scheme will increase significantly outside the zoned lands. Future
demand estimates are as follows:

As can be seen there is an expected marginal drop in water demand on the
Ballyduff/Ballylemon/Ballyhane scheme over the coming years due to the rural nature
of the scheme, the limited amount of zoned land and the expected results of ongoing
water conservation works. It should be noted that water conservation targets are
subject to substantial mains replacement under the water conservation project.
The Glenavadden springs have limited capacity; therefore augmentation from
Dungarvan Tower will be required long term in the absence of an alternative source.
Ballyhane borehole has excess capacity but elevated nitrate levels put this source at
risk. There is currently no storage on the Ballyhane source. A source protection plan
is required for the Ballyhane source. Upgrade of pipework connecting to the LCB at
Cappoquin is proposed to facilitate transfer of water in the event of a pollution
incident and to avail of storage capacity on the LCB scheme. Local storage provision
is also required. Preliminary cost estimate of €1.50M includes for local upsizing of
approx. 7.0 km of 200 dia. mains connecting west to Cappoquin and east towards
Dungarvan with additional storage capacity at an appropriate location and elevation.
West Waterford Regional Water Supply Scheme
Stage 4 – Development of Headworks, Treatment & Principle Trunk Mains
The West Waterford Regional Water Supply Scheme will replace or augment up to 53
existing water supply schemes currently producing in excess of 10,000 m3/d from
numerous sources most of which are at high risk of pollution, with inadequate or no
storage and at or near capacity. A list of the water supply schemes within the West
Waterford Regional area is included in Appendix 5. Preliminary future water demand
estimates to the year 2034 for the region indicate a regional demand of 16,000 m3/d
inclusive of 8,500 m3/d for Dungarvan Town and its environs. Current source and
storage capacities in the region are over taxed with no spare capacity for existing
36
Waterford County Council Water Services Investment Programme Assessment of Needs 2007-2009
______________________________________________________________________________________
development pressures in most areas. The regional scheme will provide security of
supply to the numerous towns and villages in the region.
The most likely source for the scheme is the Blackwater River, which has a recorded
low flow of 7.67 m3/s at Ballyduff. The river is a designated salmonid river under the
EC (Quality of Salmonid WatersRegulations) 1988, SI No.293 of 1988. The proposed
abstraction would have a minimal impact on the river flow. It is envisaged that an
intake and treatment plant would be located a short distance upstream of Lismore on
the Blackwater River from where treated water would be pumped to a reservoir on a
nearby hillside, located at an elevation as is necessary to supply a wide area by gravity.
Preliminary cost estimates for the above proposals of € 65M are based on a run of the
river abstraction, treatment plant, regional storage reservoir and key strategic trunk
mains.
4.4.1/5 Kilmacthomas Water Supply
The Kilmacthomas Water Supply Scheme serves the town of Kilmacthomas and the
hinterland to the south. The scheme has two discrete service areas separated by a
closed valve in the centre of Kilmacthomas. The primary source for the north side of
town is springs collected in a tank at St. Declan‟s Community College. This source
feeds the school directly and pumps to Kilmacthomas Reservoir TWL 65.63 mO.D.
and capacity 118 m3. The Kilmacthomas reservoir dates back to 1924. Two nearby
spring sources can augment the reservoir during summer periods. To the south the
area is supplied from the Ballyogarty well directly into the supply network. The
Ballyogarty well has a test yield of 234 m3/d. The source has recorded elevated levels
of nitrates and is classified as high risk of pollution. There is a second small reservoir at
Currabaha East TWL 45.46 mO.D., capacity 68m3 which is fed from Ballyogarty.
Augmentation of supply from the neighbouring scheme of
Kill/Bonmahon/Annestown is required during peak summer demand by opening a
boundary valve.
The Kilmacthomas Water Supply is currently included in the Water Services
Investment Programme 2005-2007 to advance through Planning. The Scheme will
require additional or alternative sources and treatment. There is a substantial area of
land zoned for residential and industrial development in Kilmacthomas. Development
pressure is evident by 239 houses currently at planning stage. A review of existing and
future demands is as follows:

The existing scheme has difficulty in meeting current peak demands in the summer
time and augmentation is required from the adjacent Kill/Bunmahon scheme. With
substantial existing development pressure in Kilmacthomas the upgrade of the water
supply scheme is now a priority. Additional source capacity is required to
accommodate future demand assessment. All feasible source options will be examined
in the Preliminary Report including groundwater and linking to the adjacent East
Waterford Water Supply. Provision of 795m3 storage capacity to provide 24 hrs
storage for security of supply and collection network upgrade to accommodate future
peak flows is also proposed. A preliminary cost of €1.9M based on the above
proposals is included.
4.4.1/6 Portlaw Water Supply
The Portlaw Water Supply Scheme consists of a spring source at Laherden which feeds
the reservoir TWL 74.7 mO.D. by gravity. A supplementary borehole at the reservoir
augments the spring source. From the reservoir the town of Portlaw and the
immediate surrounding areas are fed by gravity. There is a PRV controlling pressures
in the centre of town. There are substantial lengths of old mains and service
connections in poor condition in the town. Portlaw Water Supply Scheme is included
in the Water Services Investment Programme 2005-2007 to advance through Planning.
A Preliminary Report is currently being prepared and is expected to be finalised in
January 2007. Additional or alternative sources are being considered and trial well
drilling was completed in October 2006.
The spring source is collected in a buried concrete tank located in boggy ground to the
south of Portlaw. The source capacity is untested but inlet reservoir flows dipped to
288 m³/d in August 2005, from an average of 459m³/d. A safe yield somewhat less
than 458 m³/d is expected. The reservoir is a partially buried reinforced concrete
structure, capacity 427m³. The water treatment consists of chlorination, fluoridation
and pH correction. Water quality following treatment is adequate. An outbreak of
cryptosporidium in November 2006 demonstrates the risk status of the groundwater
source.
38
Waterford County Council Water Services Investment Programme Assessment of Needs 2007-2009
______________________________________________________________________________________
There are currently 467 domestic and 52 non domestic connections on the scheme
with an average demand of 458 m³/d of which 216 m³/d is UFW. There is substantial
residential and industrial zoned land in Portlaw. There are currently 216 houses at
various stages of planning and proposals for a large business park on 26 acres within
zoned lands in Portlaw, representing significant development pressure. The existing
and future demand estimates are as follows:

The predicted increase in non domestic demand reflects the large area of industrial
zoned land (98 acres) in Portlaw and the current proposals at planning stage for a
business park over 26 acres of zoned land.
The safe yield of the existing spring source is not sufficient to accommodate future
development in Portlaw. Additional or alternative water sources are required. The
option of local groundwater sources will be evaluated through trial drilling as part of
the Preliminary Report process. Alternative source options such as connection to the
EWWSS will also be considered. The existing reservoir will require augmenting to
provide 24 hours storage for security of supply for the design demand estimate of 1575
m³/d. The distribution network in Portlaw is in poor condition with difficult access to
pipes located at the rear of properties in the town. In many instances there are house
extensions located directly above the watermain. Substantial mains replacement in the
centre of town will be required. Preliminary cost estimate of €3.0M is included for the
above proposals.
4.4.1/7 Ballyduff, Kilmeaden Water Supply Scheme
The water supply scheme serves the zoned lands at Ballyduff (Lower) and Kilmeaden
and the intervening hinterland. There are two separate sources supplying two discrete
areas on the scheme separated by closed valve. To the East the area including the
eastern portion of Ballyduff is supplied from the Adamstown Treatment Plant on the
East Waterford Water Supply Scheme. The area to west including Kilmeaden is
39
Waterford County Council Water Services Investment Programme Assessment of Needs 2007-2009
______________________________________________________________________________________
supplied from the Kilmoyemoge Holy Well via the Hickey Reservoir TWL 171.39
mOD. The average flow from the Kilmoyemoge source meter over the last 12 months
was 314 m³/d.
The safe yield of the Kilmoyemoge well is estimated at 295 m³/d from observations
during dry summer months. Water quality is generally satisfactory. Treatment consists
of chlorination and fluoridation. The storage reservoir is a precast circular concrete
tank, volume 164 m³ dating from the mid 1970‟s. The reservoir is leaking at present
and remediation proposals are being considered. The distribution system requires
substantial maintenance due to failure of pipe collars on various sections
There are approximately 225 domestic and 35 non domestic connections on the
scheme. A water audit undertaken as part of the Water Conservation Scheme recorded
an average demand of 257 m³/d including 139 m³/d UFW. The scheme services the
zoned lands of Ballyduff Lower and Kilmeaden with substantial residential and
industrial zoned lands available for development.
Significant development is expected on the scheme in view of the proximity to
Waterford City and the Waterford City Bypass (currently under construction). There
are currently 60 houses at planning stage within available zoned lands. Future demand
estimates are as follows:

The capacity of the existing scheme is insufficient to cater for future demands in the
short to medium term and this will impact on larger development proposals in the
short term. The existing storage capacity at 164m³ does not offer 24 hour storage at
existing demand and is leaking. A new reservoir of 530 m³ to provide 24 hour storage
at design flow is recommended. The elevation of the reservoir should be in the region
of 140 mO.D., significantly less than the existing reservoir at 171.3 mO.D. An
additional or alternative source is required with connection of the scheme to the
40

EWWSS the most probable solution. Substantial main s replacement is required to
achieve target UFW levels and to ensure security of supply. A preliminary cost estimate
of € 1.20M is included for storage provision and connection to the EWWSS including
5.0 km rising/distribution main and booster pumping.
4.4.1/8 Kill/Bunmahon/Annestown Water Supply Scheme
The scheme is supplied by two separate sources each feed into separate areas. The
Ballyvadden stream source supplies Ballyvadden Reservoir TWL 57 mO.D. via slow
sand filters. Bunmahon Village is supplied by gravity from this reservoir with outlying
areas supplied via booster pump. The second source is taken from the Mahon River
and treated at Ballylaneen Water Treatment Plant. From Ballylaneen water is pumped
2km to two adjacent reservoirs at Ballyvadden Hill TWL 104.28 mO.D. The
Ballyvadden Hill reservoirs feed Ballylaneen, Kill and Annestown Reservoir TWL
63.44 mO.D. by gravity. Annestown village is supplied via Annestown Reservoir. The
Scheme is connected to the Kilmacthomas Water Supply Scheme at a closed valve
south of Ballylaneen which can facilitate emergency supply from Ballyvadden Hill
reservoir to the Kilmacthomas Water Supply Scheme.
The average supply from the River Mahon source via the Ballylaneen Water Treatment
Plant was 266 m³/d over the last 12 months. The treatment plant at Ballylaneen
includes coagulation, sedimentation, pH correction and filtration. It is currently at
capacity. The Ballyvadden stream source supplied an average of 97 m³/d over the last
12 months. Treatment consists of slow sand filtration. There are 3 filter beds with
combined area of 78m² suggesting a capacity based peak filter rate of 0.15m/hr with
one filter bed out of commission for maintenance of 187m³/day. Slow sand filtration
is insufficient to remove periodic colour from the water source. Storage on the scheme
consists of 4 reservoirs. The two reservoirs on Ballyvadden Hill have a combined
storage volume of 510 m³ (360 + 150) and TWL 104.28 mO.D. The low level
reservoir at Ballyvadden has a storage volume of 176 m³/d and TWL 57 mO.D.
Annestown reservoir has a storage volume of 182 m³ and a TWL of 66.05 mO.D.
There are currently 388 domestic and 67 non domestic connections on the
Kill/Bunmahon/Annestown Water Supply Scheme with an average demand of 363
m³/d of which 132 m³/d is UFW. The water supply scheme served the settlement
zones of Annestown, Ballylaneen, Bunmahon, and the intervening hinterland. There is
a substantial area of land zoned for residential development. It is not expected that
service demand will increase outside of zoned lands. Significant development pressure
on the scheme is evidenced by 122 houses currently at planning stage. There is also
expected to be a peak tourism demand associated with the coastal villages of
Bonmahon (Blue Flag) and Annestown. The current and future demand estimates are
as follows:

The capacity of the existing treatment plant at Ballylaneen is approximately 265m³/d.
The Ballyvadden Stream source has a minimum flow estimate of 340 m³/d which
would suggest that abstraction in excess of the available treatment capacity of 187m³/d
is not feasible. Current estimated available treated water capacity of 450 m³/d is not
sufficient to accommodate future demands in the short term.
Extending the supply from EWWSS to supply Kill/Bunmahon/ Annestown and the
additional schemes on route was included in Stage 3 proposals for the East Waterford
Regional Water Supply Scheme Preliminary Report. A preliminary cost estimate of €
1,850,000 is included for the above proposals.
4.4.1/9 Stradbally Sheskin Water Supply Scheme
The Scheme supplies the village of Stradbally and the hinterland to the south west as
far as Ballyvoyle. There is a single source taken from an impoundment on the Tay
River. Water is treated with alum dosing and pressure filtration and pumped to the
Stradbally Reservoir TWL 94.8 mO.D., capacity 113m3. Water gravitates to Stradbally
and is boosted to Sheskin.
The Tay River source has an estimated DWF of 0.26m³/s which suggests significant
spare capacity based on current average demand of 191 m³/d. The treatment plant
capacity is approximately 36 m³/hr or 720 m³/d based on 20 hrs operation. The
42
Waterford County Council Water Services Investment Programme Assessment of Needs 2007-2009
______________________________________________________________________________________
limiting factor is the 4” rising main from the treatment works to the reservoir at a
distance of 2km. Maximum flow via the 4” rising mains would be approximately 20
m³/hr or 480 m³/d based on 24 hr pumping.
There are currently 235 domestic and 40 non-domestic connections on the scheme
with an average demand over the last 12 months of 191 m³/d including 68 m³/d
UFW. The scheme serves the settlement zone of Stradbally with significant residential
development pressure evidenced by 155 houses currently at planning stage. Existing
and future demand estimates are as follows:

There is substantial source and treatment capacity available on the scheme. The rising
main from the treatment plant to the storage reservoir is in poor condition with
numerous leaks due to deterioration of the Class B Asbestos pipe and proves very
problematic to maintain as it is located beside the river. The storage capacity of 113m³
does not provide 24 hrs storage and increased capacity will be required. Access to the
reservoir is inadequate requiring crossing of fields. Preliminary cost estimate of €0.8M
includes for rising main replacement, additional storage provision and access roadway.
4.4.1/10 Rathgormuck/Carrick on Suir Environs Water Supply
There are eight small public water supply schemes located immediately to the south of
Carrick on Suir within County Waterford. Seven schemes are located at relatively high
elevation ranging from 120mO.D. to 170mO.D. with the exception of Clonae Power
ranging in elevation from 60 90m O.D. The schemes listed from west to east are
summarised as follows:

adjacent to a septic tank and slurry spreading and the Rathgormuck supply is located in
the local Co-Op Yard. The Clonae Power spring source is categorised as high risk. It is
proposed to amalgamate the schemes for security of supply with connection to the
adjacent Carrick on Suir Water Supply if feasible or as an individual scheme with
common storage provision. The scheme is included in the Water Services Investment
Programme 2005 – 2007 with approval to advance through planning. Preliminary cost
estimate of € 2.35M is included to cover the above proposals.
4.4.1/11 Clonmel Environs Water Supply Scheme
The Croan, Derrinlaur, Glennagad, Kilgainey, Kilmacomma, Kilnamack, Knocklucas,
Lyranearla and Poulnagunoge Public Water Supply Schemes supply areas contiguous
to Clonmel. Water from Clonmel UDC supplies upwards of 42 connections in the
Croan, Kilgainey and Knocklucas Schemes. The remaining schemes in the area, serving
105 connections, are sourced from groundwater. The borehole for the Poulnagunoge
scheme is rated as highly vulnerable to pollution, indicating that its long-term viability
is questionable and provision should be made to replace it. Storage is limited to a 63m3
reservoir on the Kilmacomma WSS at TWL 65 mO.D. and a 10m3 storage tank on the
Glennagad WSS at TWL 216 mO.D. It is proposed to amalgamate these schemes to
provide security of supply.

The groundwater based schemes serve a range of ground levels from 210 – 130 mOD
(in Glennagad) to 20 – 30 mOD (in Derrinlaur). Ground levels in the schemes
supplied from Clonmel UDC vary 15 and 65 mOD. From a rationalisation viewpoint,
the best option for supplying these schemes is from Clonmel Town Council or
Tipperary SR Schemes in the area, for both of which upgrade proposals have recently
been prepared.
Additional storage consisting of three 120m3 final water storage volumes of TWL‟s of
217, 160 and 90 mOD with 100 and 150 mm rising/distribution network would be
required to service a range of ground levels in the area. Booster sets and
interconnection pipework between schemes would be required to accommodate water
transfer from Clonmel UDC presuming adequate water is available. Preliminary cost
estimate of € 2.0 M is included for the above proposals.
4.4.1/12 Bundled Schemes Water Quality Improvement Proposals
In view of the large number of small public water supply sources associated with the
103 public water supply schemes in County Waterford and the relatively large scale of
the necessary water quality provisions countywide it is proposed to take a bundled
scheme approach. A list of the schemes requiring water quality provisions and the
proposed works are included in Appendix 4 and summarised below as follows:
UV Treatment:
A total of 30 schemes to be fitted with UV disinfection as a back-up to the existing
chlorination system, in order to ensure microbiological quality.

4.4.2 Sewerage Schemes
4.4.2/1 Dungarvan Sewerage Scheme
Dungarvan Sewerage Scheme, currently at commissioning stage will provide secondary
treatment capacity for 25,000 p.e. with a discharge to sea outfall. The design of the
plant to the year 2022 was based on the following:
Table 4.4.2/1a Dungarvan Wastewater Treatment Plant Existing Design Loads
p.e. Flow (m³/d)

Future Domestic 5817 1161
Existing Non Domestic 6783 1413
Future Non Domestic 2567 378
Total 25,000 4,920
The latest population estimate for Dungarvan Town and the immediate vicinity served
by the collection system is 13,422 people based on the July 06 Geodirectory House
Count and an average occupancy rate of 3 person/house. In addition there are 396
houses currently at various stages of planning. Assuming all of these developments
proceed there is a potential short term population of 14,610 in the catchment area.
There has been significant commercial development in Dungarvan in recent years with
a large shopping mall development and numerous light industrial units. There are also
significant efforts to attract industry to the town following the closure of Waterford
Glass. In economic terms it is accepted that on average 34% of the population can be
anticipated to be available to the labour force. The anticipated increase in population
of Dungarvan & its environs will require the creation of substantial additional jobs
within the town. The industrial component of this will be catered for with the
expansion of the local enterprise parks and the redevelopment of the Waterford
Crystal site. The Town Development Plan will facilitate the generation of employment
opportunities by ensuring that sufficient and appropriate land is zoned and available
for development. On this basis an assumption that the non-domestic loading for
Dungarvan should increase to reflect the increase in scale of the residential sector. The
revised 2009, 2014 and 2034 load projection for Dungarvan is as follows:

Headroom is included at 10% of load to reflect uncertainties in future load estimation
particularly in relation to industrial loading with the possibility of a single development
having a significant impact on load estimates. Additional Treatment Capacity of 10,000
p.e. is proposed to accommodate current development trends and to reflect the
likelihood of significant additional future loading as investment is attracted to the
county town. The existing treatment plant now at commissioning stage cost
€11,276,200 or €451 per p.e. based on tender prices in 2003. It is expected that unit
costs per p.e. to provide additional capacity would be greater than those on the original
contract due to the various site and design constraints over and above working on a
green field site. The cost to provide additional treatment capacity is estimated at €600
p.e.

4.4.2/2 Ballinroad Sewerage Scheme
Ballinroad is a satellite settlement to Dungarvan which has experience concentrated
residential development in recent years. The current population at Ballinroad is
estimated at 1,302 based on housing counts and an assumed occupancy rate of 3
persons/house. There are 228 houses in Ballinroad currently at various stages of
planning. Assuming all these developments proceed in the short term the potential
population in Ballinroad is 1986.
Proposals were considered to divert the waste flow from Ballinroad to the Dungarvan
Plant as the Ballinroad Treatment Plant (cap 750 p.e.) is currently overloaded.
However, the consequences of development pressures in Dungarvan which limit
available capacity in the Dungarvan Wastewater Treatment Plant make this option
strategically impracticable. For the purpose of strategic needs assessment we have
assumed the treatment capacity at Ballinroad will be augmented or replaced. The
Ballinroad Treatment plant is on a relatively compact site discharging to estuarine
waters at the mouth of the Glendine River. The future population at Ballinroad is
expected to rise to 2,500 over the next 25 years in view of the zoned land available and
recent development trends. A preliminary cost estimate of € 1.50M is proposed based
on a 2,500 p.e. treatment plant requirement.
4.4.2/3 Tramore Sewerage Scheme – Wastewater Treatment Plant Design
Loading Review
The Tramore Wastewater Treatment Plant currently at construction stage will provide
secondary treatment for a population equivalence of 20,000 during summer months
with a reduced design loading off season of less then 14,000 pe. Effluent discharge is
via a 2km long sea outfall.

14,421 which reflect significant residential development in recent years. This is
expected to continue with 460 houses currently at various stages of planning. There are
also two major shopping complexes and a new school at planning stage in Tramore. In
addition available zoned land in the settlement zone includes 105 acres residential and
6 acres tourism. The existing and future load estimates for Tramore are as follows:

Additional treatment plant capacity of 10,000 p.e. is required to accommodate current
development trends. The assumed unit cost per p.e. of additional treatment capacity is
predicted to be greater than the unit contract costs for the existing treatment plant at €
421/pe (incl. VAT) due to the site and design constraints involved. The cost to
provide additional treatment capacity is estimated at €600 p.e.

4.4.2/4 Tramore Sewerage Scheme – Collection System, Stage 2
The existing collection system in the old part of town is a combined system draining to
the Promenade pumphouse. There is also pumped flow to the Promenade
pumphouse from a sub catchment via the Cove pumphouse. More recent
developments are serviced by foul and storm systems, the former discharging to the
50

______________________________________________________________________________________
existing old town combined system with the latter discharging to existing watercourses
or the sea, as appropriate. Works are currently underway to redirect the pumped
output from the Promenade pumphouse to the site of the new wastewater treatment
plant at Riverstown, which is currently under construction. Storm water overflows
discharge to the sea to provide relief to the sewers where appropriate.
Tramore Sewerage Scheme – Collection System, Stage 2 is included in the WSIP 2005-
2007 to advance through planning. A Preliminary Report is currently being prepared to
assess the capacity, condition and levels of infiltration on the existing network. The
report will identify areas of unsatisfactory hydraulic performance under future flows
and make recommendations on resolving deficiencies and undercapacities in the
network. Existing overflows discharging to the marine environment require urgent
investigation and remedial measures to ensure compliance with the quality of Bathing
Waters and/or Urban Wastewater treatment Regulations as appropriate. The report
will assess existing and future storm flows with a view to minimizing pumping costs
and overflows with an optimum solution to reduce storm overflows to an acceptable
level. A preliminary capital cost for provision of the required collection network
improvements is € 10.2M
4.4.2/5 Waterford Grouped Towns & Villages Sewerage Scheme
The Waterford Grouped Towns & Villages Sewerage Scheme which consists of seven
towns, namely, Ardmore, Ballyduff/Kilmeaden, Cappoquin, Dunmore East,
Kilmacthomas, Stradbally and Tallow is included in the Water Services Investment
Programme 2005-2007 with a start date in 2007. In view of the increased level of
residential developments in recent years it is considered prudent at this stage to review
the design domestic load included in the Design Review Report dated Nov. 2004 for
the above scheme.

4.4.2/6 Lismore Sewerage Scheme
The existing Lismore Sewerage Scheme consists of a combined collection network
discharging to an extended aeration treatment plant with discharge to the River
Blackwater. The capacity of the treatment plant is nominally 1600 p.e.; however the
secondary settlement tank can only accommodate 1300 p.e. at 6 DWF. The hydraulic
load on the plant is problematic due to a lack of storm water drainage in Lismore. The
current population of Lismore based on July 06 Geodirectory and an occupancy rate
estimate of 3 persons/house is estimated at 1635. There are an additional 240 houses
at various stages of planning and a further 45 acres of residential zoned lands available
for development within the settlement zones of Lismore. The estimate future load for
Lismore is as follows:

The existing extended aeration plant is overloaded and requires additional capacity to
provide 4500 p.e. to cater for future development loads. The existing plant is located
in an old quarry site which affords no room for conventional expansion. An
alternative site to provide treatment in parallel or an alternative treatment plant to
replace existing facilities is required.

It is essential for the efficient operation of the existing and proposed treatment plants
to minimise the surface water contribution to the combined network. A storm water
collection system is required to facilitate transfer of surface water connection from the
existing combine system and for future development. For preliminary costing
purposes a length of 3.5km of storm water sewer is proposed which includes storm
water drainage for all main roads in Lismore Town. In addition significant combined
network upgrade is also required to accommodate future flows and minimise
infiltration. Cost estimate for the above proposals are as follows:

4.4.2/7 Portlaw Sewerage Scheme
The Portlaw Sewerage Scheme consists of a combined gravity collection system with a
1750 p.e. estimated aeration treatment plant discharging to the Clodiagh River. There
is also a small combined collection system on the south side of the River Clodiagh
feeding a septic tank prior to discharge to the river. The current population estimate in
Portlaw based on the July 06 Geodirectory and an occupancy rate estimate of 3
persons/house is 1638. There are currently 216 houses at various stages of planning in
Portlaw with an additional 82 acres of residential zoned land available for development
within the settlement zone. There is no major industry and limited commercial load
on the scheme; however commercial loading is expected to increase in view of the
recent development of serviced industrial site on the industrial zoned lands in Portlaw
and in line with population increase. The future load estimate for Portlaw Sewerage
Scheme is as follows:

4.4.2/8 Sludge Management Plan – East County Satellite Centre
A Sludge Management Strategy for County Waterford has been prepared in accordance
with the guidance document „Sludge Management Plans: A Guide to Their Preparation And
Implementation (DoELG 1998). The strategy proposes a sludge treatment Hub centre at
Dungarvan with two satellite sites in the east and west of the county to supply the Hub
centre. The Hub Centre is being progressed as part of the Dungarvan Sewerage
Scheme based on a thermal drying process which produces a relatively small quantity
of material in comparison with alternative treatment options and a granulated or
pelletised form of final product, which is the preferred form of biosolids for
agricultural application. The Dungarvan Sewerage Scheme is included in the WSIP
2005-2007 and is currently at commissioning phase.
A sludge satellite centre for the west of the county is being progressed as part of the
Waterford Grouped Towns & Villages Sewerage Scheme which is included in the
WSIP 2005-2007. The location of the satellite centre is at Cappoquin. The Cappoquin
Satellite Centre will be required to store sludges emanating from septic tanks (Primary
Sludge), and sludges from Secondary Wastewater Treatment Plants (Secondary Sludge)
separately requiring two storage tanks. The sludge at the Cappoquin Sludge Satellite
Site will need to be dewatered to a level of 15 – 20% dry solids, as this is the range
which will be acceptable at the Sludge Hub Centre.
A parallel sludge satellite centre is required for the east on the county requiring sludge
storage and dewatering facilities. Based on cost estimates prepared for the Cappoquin
Sludge Satellite Centre a preliminary cost estimate of €3.0M is included

______________________________________________________________________________________
There is a substantial area of institutional, industrial and special commercial zoned land
identified in the County Development Plan 2005-2011on the environs of Waterford
City. This area already contains the Waterford Institute of Technology, Waterford
Business and Technology Park and proposals for a large retail warehouse development.
The industrial zoned land including the current development within the Business and
Technology Park is 73.9 acres. The current development pumps wastewater to the city
collection network. A further 60 acres of special commercial related zoned land is
available. There is an existing development proposal at planning stage for a 15,939 sq.
m retail warehouse located within this zoned land. In view of the development
potential of the area adjacent to the city and the college campus the provision of
wastewater treatment capacity to cater for full development of the zoned land is
proposed. The total area of commercial and industrial zoned land is 134 acres.
Assuming full development at light industry loading rate of 100 p.e. /acre. A
preliminary cost estimate of € 9.00M is proposed for the provision of a collection
system, a 13,400 p.e secondary treatment plant and discharge to the Suir River Estuary.
4.4.2/20 Annestown Sewerage Schemes
Annestown is a picturesque village located on the coast with scenic views and a
popular summer beach destination for visitors. Development in the village in recent
years has been of low density and small scale in nature. The current population of the
village is estimated at 72 persons based on house counts. The Waterford County
Development Plan 2005-2007 identifies a development strategy for Annestown to
develop the adjoining lands to give some depth to strengthen the village settlement and
promote some needed commercial (retail) development for the permanent population.
There is a current planning application for 38 houses with an additional 8.6 acres of
land zoned for residential development. A future design population estimate of 300
p.e. is included for cost estimation.
The existing wastewater collection system in Annestown consists of a box culvert
originally discharging spring water to the Annestown stream. In the intervening years
this box culvert was utilised to connect foul sewer connections from a number of
houses and a septic tank was installed to intercept the box culvert prior to discharge to
the Annestown stream. A 300 p.e. package treatment plant and foul collection network
is proposed. The cost estimate for the above proposals is as follows:

4.4.2/21 Rathgormack Sewerage Schemes
The village of Rathgormack is located 11kms southwest of Carrick-on-Suir. There is
no public sewerage system at present. The current population of Rathgormack is 66
based on July ‟06 Geodirectory House County and an occupancy rate of 3
persons/house. There are currently 39 houses at various stages of planning and an
additional 31 acres of zoned land available for development with the settlement zone.
Proposals include for a 350 p.e. treatment plant and foul collection system with
discharge to adjacent stream of the Clodiagh River. The treatment plant should be
designed with future duplication in mind in view of the relatively large area of zoned
land available. A preliminary cost estimate of € 750,000 is proposed for the provision
of a collection system, 350p.e secondary treatment plant and discharge to adjacent
stream
4.4.2/22 Bundled Small Sewerage Schemes
There are 14 locations which have been allocated residential zoned lands in the
Waterford County Development Plan for which there are no public wastewater
services in place or the services are limited to small public septic tanks serving small
council housing estates. A summary of the existing populations and the available zoned
lands is as follows:
Table 4.4.2/18 Bundled Small Sewerage Schemes

It is proposed to progress procurement of package treatment plants for the above 14
settlement zones with future population ranging in size from 319 to 34 persons as a
bundle. Preliminary cost estimates for, site acquisition package treatment plants and
associated collection pipework is € 3.00M

5.0 REQUIREMENTS FOR INVESTMENT 2007 – 2014
Circular Letter L2/06 from the DoEHLG calls on Local Authorities to examine from
a strategic perspective the main requirements for water services investment over the
period 2007 – 2014.
Having regard to the objectives set out in the County and Local Area Development
Plans for Waterford, and in the light of continued growth in the housing and
commercial/industrial sectors, the main requirements in this area relate to the long-
term provision of adequate water and wastewater throughout the County. The existing
infrastructure deficit for both water and wastewater services is seen as a major
constraint on development. It is essential that the recommendations for
improvements to water supplies particularly in the west of the county proceed to
planning at an early stage. In addition, the provision of sewerage infrastructure and
treatment for the towns not addressed pre 2007 is essential if proposed development
areas are to be fully utilised.
The environmental and statutory justification of including schemes for the period 2007
to 2014 is undertaken in Appendix 1, using the same criteria detailed in the preceding
section of this report.
The full list of investment priority requirements covering 2007 to 2009 is shown in
Table A and longer term strategic investment 2010 to 2014 is shown on Table B
overleaf.

6.0 PUBLIC CONSULTATION
This document is available for public consultation and comment for a one month
period. Following public consultation, all comments received will be considered and a
composite report will be prepared. This Assessment of Needs Report will be presented
to the Waterford County Council Transport and Infrastructure Strategic Policy
Committee (SPC) and the outcome from the SPC will be placed on the agenda of
Waterford County Council‟s monthly meeting and will then be forwarded to the
Department of Environment, Heritage and Local Government.
Formal comments and submissions should be addressed, before the closing date
advertised in the public notice, published in the local newspaper, to:
John O‟Flynn, Director of Services & County Engineer
Waterford County Council
Civic Offices
Dungarvan
Co. Waterford.
Water Services Investment Programme
The Department of the Environment, Heritage and Local Government is funding a
Water Services Investment Programme evaluated in the sum of €167,587,000 over the
period 2005 – 2007 in the Waterford County Council area. This programme is detailed
in Appendix 3. For the period 2007 – 2014 a number of additional investment
programmes are considered in this Assessment of Needs. These are set out in detail in
Table A & B below.
The following explanatory note highlights the various phases, which investment
schemes undergo from conception to completion.
Phasing of Schemes
Any Scheme going through a series of life cycle stages, between the concept stage and
the completion stage. The full list of life cycle stages applying to a generic project
consists of the following stages:-
Concept
Feasibility
Outline Design
Detailed Design
Statutory and Legal
Procurement
Construction
Completion/Facility/Management

______________________________________________________________________________________
The Department of the Environment, Heritage and Local Government has identified a
number of life cycle stage milestones at which Local Authorities must make formal
submissions to the Department and receive formal approvals. The generic stages at
which formal submissions and approvals are necessary are the:-
Approval to enter planning phase
Preliminary report stage (which establishes scheme feasibility)
The preparation of contract documentation and detailed design
The contract advertisement to procure construction services, where applicable.
The approval to tenders, which allows construction to commence
The final account stage.
The operation phase.
For projects less than € 635,000 full management responsibility has been devolved to
the local authority on foot of Department Circular L1/06 and L7/06
which substantially revises the above approvals requirements and should offer a
reduction in the life cycle of some projects.
Many of the schemes under consideration are only at the concept/feasibility stage in
their individual life cycle. Accordingly, it should be noted that future cost estimates for
projects which may not reach construction phase until several years from now must be
viewed with some degree of caution, as the estimation of future scheme construction
costs can only be undertaken after detailed evaluation through the life cycle stages
listed above.

7.0 RECOMMENDATION OF ASSESSMENT OF NEEDS
The list of new schemes identified has been assessed in accordance with the
justification criteria, outlined in Appendix 1 under the Heading of High or Medium.
As a result, a single list has been identified and this is as set out in Table A overleaf.
Table B lists a number of schemes, which following an examination from a strategic
perspective, are included for longer-term water services investment. Table A also
includes indications, subject to the caveat in this report, on cost estimation. Many of
the schemes go through a generic life cycle, which can stretch to several years.
Accordingly, the entire list should be progressed with investment for studies, which are
generally low cost, being matched over the investment timeframe with construction
costs, which can be significant.
Note: Water conservation proposals, which have been approved under the National
Water Conservation Programme, 2003, in accordance with Department Circular
L9/03, and have, therefore, been excluded from the list of new schemes identified in
the Assessment of Needs and included in Table A, on the basis that they have been
separately funded under an additional programme.
It is recommended that following SPC approval and public consultation, an assessment of all comments
received will be made. The document will be revised as appropriate, placed on the agenda of Waterford
County Council’s monthly meeting and will then be forwarded to the Department of the Environment,
Heritage and Local Government.
