Redwood City Expanded Recycled Water Program Feasibility Study                                                                        iii
Executive Summary

ES.1       Background
Redwood City (the City) is 100% reliant on one source of potable water supply, the San
Francisco Hetch Hetchy regional water system. Currently, the City is consuming approximately
1,000 acre-feet per year (AF/yr) over the contractual (wholesale) supply assurance of 12,243
AF/yr. The Redwood City Water Use Forecast for 2000 to 2020, dated June 20, 2002 (prepared
by John Whitcomb, PhD), includes water supply projections associated with future housing,
employment, and population, etc. The Water Use Forecast explores future water supply
scenarios including the “worst case” scenario that excludes any water conservation and a
scenario that takes into account passive water conservation. The potential water supply
savings associated with an active water conservation scenario are addressed in the City’s
Urban Water Management Plan. Based on these forecasts and planning, the City will need
additional water supplies to meet both current and future needs.

The City has four options to reduce current demands on the Hetch Hetchy supply, in order to
comply with the supply assurance and provide supply for future growth:

   1. Negotiate water transfers from other agencies that use the Hetch Hetchy regional
      system

   2. Negotiate a new source of potable water supply via the regional system (“wheeling”)

   3. Implement water conservation measures

   4. Implement a water recycling program for landscape irrigation and industrial uses

This study builds upon the joint recycled water pilot project being operated in Redwood Shores
by the South Bayside System Authority (SBSA) and the City, and on the Water Recycling
Feasibility Study for the Redwood Shores Area (Kennedy/Jenks Consultants, January 22,
2002).


ES.2       Market Assessment
Three geographical areas within the City were reviewed relative to providing a new market for
recycled water use. The areas generally include Redwood Shores, the “Greater Bayfront Area”
and Central Redwood City. Potential recycled water uses are primarily for landscape irrigation
in Redwood Shores and Central Redwood City. Some industrial uses, and potential for internal
uses such as toilet flushing, exist primarily in the Greater Bayfront area and, to a lesser extent,
Central Redwood City.

To facilitate subsequent evaluations in this report, the potential customers were grouped into
four classifications:




Water Recycling Feasibility Study for Redwood City                                            ES - i
Priority 1 Customers:

   ●   Existing First Step Project customers (dedicated landscape irrigation meters)

   ●   Customers with agreements in place for service

   ●   Potential customers or groups of customers that have relatively large irrigation or
       industrial demands, and are adjacent to potential transmission pipeline corridors

Priority 2 Customers:

   ●   Potential customers or groups of customers that have small to medium-sized demands,
       and are adjacent to or relatively near potential transmission pipeline corridors

Priority 3 Customers:

   ●   Potential customers or groups of customers with relatively small demands, that are
       either remote from potential transmission pipeline corridors, or may have higher
       customer site retrofit costs

   ●   Proposed future developments or re-development sites, or existing customer sites that
       are served by private wells or the California Water Service Company

Priority 4 Customers:

   ●   Landscaped sites that are not presently irrigated or other uses that have very low
       demands

   ●   Sites that are very remote from potential transmission pipeline corridors, require
       significant additional pumping because of site elevation, or appear to have very
       challenging/expensive customer site retrofit costs

Priority 1 and 2 customers represent the most viable customers that are ready to be served, if
the City implements a mandatory use ordinance or obtains individual agreements for service.
The annual recycled water demand from Priority 1 and 2 customers represents the most
reasonable minimum estimate of potential “new water supply” for integrated water supply
planning. Some portion of Priority 3 customer demands appear able to be cost-effectively
served, however, service in many cases is dependent upon establishing institutional
agreements to replace a current water supplier or future development or redevelopment
activities. Priority 4 customers do not appear viable for a number of reasons. Although they
were considered initially, their demands do not appear to be a source of “new water supply” for
the City.

The potential recycled water demand for Priority 1, 2, and 3 customers in Redwood City
appears to range between about 1,100 and 3,172 acre feet per year (AF/yr), for a Redwood
Shores only project and a City-wide project, respectively. Within these projections, about 582
AF/yr is for future developments or redevelopment projects that are in various stages of
planning.

ES.3       Alternatives Development and Evaluation
Eight preliminary alternatives were developed for hydraulic analysis. The eight alternatives
encompass a full range of possible system configurations, so different levels of service to the
three geographical areas and customer priority levels could be investigated. In addition, both
centralized and decentralized storage and pumping options were included to investigate the
cost-effectiveness of different system configurations. The alternatives ranged from small
systems (Priority 1 and 2 customers in Redwood Shores only) to City-wide systems (Priority 1,
2, and 3 customers in all three geographical areas) providing a range of new water supply from
just over 1,100 AF/yr up to approximately 3,172 AF/yr.

Preliminary estimates of capital costs and cost effectiveness (cost per acre-foot of water
delivered) were developed for the eight preliminary alternatives based on pipeline sizes and
lengths, storage and pumping capacity, treatment costs, and standby connections. The
conclusions drawn from the preliminary alternatives analysis are as follows:

   ●   The cost effectiveness of City-wide alternatives that serve only Priority 1 and 2
       customers tends to be much lower than for alternatives that include Priority 3 customers.
       When the Priority 3 customers are added to City-wide distribution systems, the cost-
       effectiveness increases by about 35%. This is because Priority 3 customers make up a
       large percentage of total potential recycled water demand outside the Redwood Shores,
       and the transmission pipeline system becomes more cost-efficient when the Priority 3
       customer demands are included.

   ●   Preliminary alternatives with centralized storage and pumping at SBSA are more cost
       effective than the alternatives with decentralized storage and pumping. The cost
       required for decentralized pump stations is greater than the cost savings realized by
       reduced pipeline sizes in the transmission system.

   ●   In an attempt to improve cost-effectiveness of a City-wide project while maintaining a
       substantial recycled water supply, fine-tuning was performed by eliminating distribution
       pipelines to customers that appeared to be relatively expensive on a cost per AF/yr
       delivered basis. A slight improvement in cost effectiveness was realized in this fine-
       tuning.

Based on the results of the preliminary alternatives evaluation, final alternatives were developed
to meet the range of the City’s projected water supply needs, while providing the best value and
preserving flexibility for future system growth and expansion. All of the final alternatives
included some level of service to Priority 3 customers. The four Final Alternatives A through D
are summarized in Figures ES-1 through ES-4. To preserve flexibility for future expansion of
the recycled water system, the transmission pipelines are sized under each final alternative to
serve all of the Priority 1, 2, and 3 customers in each of the three geographical areas (as in
Alternative B).


ES.4       Recommended Project
Based on an evaluation of cost-effectiveness, water supply, and future flexibility considerations,
Project Alternative D is recommended to the City for use in project planning and
implementation, determining a financing strategy, and in developing an initial rate and revenue




Water Recycling Feasibility Study for Redwood City                                          ES - iii
plan. Refer to Figure ES-1 for a schematic plan of Alternative D. The primary reason for
recommending Alternative D is that it is the most cost-effective project configuration that
provides an adequate water supply (1,955 AF/yr) to:

   1. Reduce existing demands on the San Francisco Hetch Hetchy regional water system to
      be within the City’s contractual supply assurance.

   2. Provide a source of future water supply for potential new developments within the City.

Alternative D also provides significant flexibility for the future, so the City can continue to explore
the benefits of additional water conservation measures, overall water supply reliability and
drought tolerance issues, water transfers and other water supply management options. If the
City requires additional recycled water supply in the future, the pipelines provided under
Alternative D are oversized to allow the system to expand across Bayshore Highway 101 into
Central Redwood City for a City-wide project (3,172 AF/yr as in Alternative B). The system
could also support expansion into adjacent communities to meet future needs if the City were to
negotiate agreements for transmission of water from SBSA to other retail water suppliers.

Additional benefits and considerations associated with recommending Alternative D are
included in Section 5 of this report.

The total estimate of probable capital cost, including facilities construction, service connections
and site retrofits, engineering, construction management, administration and a 20% project
contingency is approximately $36,819,000. The portion of this cost associated with providing
oversized pipelines for future flexibility is approximately $4,891,000. Alternative D capital costs
are summarized in Table ES-1.

ES.5       Implementation Strategy
The basic implementation strategy for Alternative D water supply and capital improvement
program is summarized in Table ES-2. The implementation concept is to simultaneously build
backbone infrastructure facilities such as treatment, pumping, storage and transmission
pipelines, while aggressively preparing in detail for customer connections and site retrofit.
Based on the experiences of other Bay area projects, customer coordination and site retrofit
requirements are typically underestimated, and actual recycled water use has fallen short of
original projections.

The proposed project could be implemented in multiple phases. Treatment, storage, pumping,
and pipeline transmission facilities to serve the Redwood Shores Area could be constructed in
fiscal year (FY) 2003/2004, and customer services and site retrofits could be constructed over a
three-year period between 2003 and 2006, so full supply benefits are obtained during the 2007
irrigation season. The Greater Bayfront Area project phase may be driven by future developer
schedules, but it is tentatively planned that the 5-mile transmission line from SBSA to the
Whipple Avenue/Highway 101 Interchange could be in place by the year 2006, while the entire
Greater Bayfront Area could be served by 2009. In this scenario, the entire Alternative D project
could be in place by 2009, which may be advantageous to the City as the Master Sales
Agreement between San Francisco and suburban purchasers will be renegotiated in 2009/2010
(contract expiration).

   Water Recycling Feasibility Study for Redwood City                                                       ES - x
Section 1: Introduction


1.1        Background

1.1.1      Water Use and Water Supply Deficit
Redwood City (the City) is 100% reliant on one source of potable water supply, the San
Francisco Hetch Hetchy regional water system. Currently, the City is consuming approximately
1,000 acre-feet per year (AF/yr) over the contractual (wholesale) supply assurance of 12,243
AF/yr. The Redwood City Water Use Forecast for 2000 to 2020, dated June 20, 2002 (prepared
by John Whitcomb, PhD), includes water supply projections associated with future housing,
employment, and population, etc. The Water Use Forecast explores future water supply
scenarios including the “worst case” scenario that excludes any water conservation, and a
scenario that takes into account passive water conservation. The potential water supply
savings associated with an active water conservation scenario is addressed in the City’s Urban
Water Management Plan. Based on these forecasts and planning, the City will need additional
water supplies to meet both current and future needs.

The City has four options to reduce current demands on the Hetch Hetchy supply in order to
comply with the supply assurance and provide supply for future growth:

   1. Negotiate water transfers from other agencies that use the Hetch Hetchy regional
      system

   2. Negotiate a new source of potable water supply via the regional system (“wheeling”)

   3. Implement water conservation measures

   4. Implement a water recycling program

Of these options, water conservation and water recycling appear to provide the only viable near-
term opportunities that can be readily planned and implemented by the City.


1.1.2      South Bayside System Authority
The South Bayside System Authority (SBSA) operates a publicly owned wastewater treatment
works within the Redwood Shores area (see Figure 1:). SBSA is a joint powers authority that
provides wastewater treatment and disposal for the cities of Redwood City, Belmont, and San
Carlos, and the West Bay Sanitary District (serving Menlo Park, Atherton, Portola Valley, and
parts of East Palo Alto). SBSA facilities provide a high level of wastewater treatment as
required by regulatory agencies for the discharge of effluent to the San Francisco Bay. With
additional treatment, SBSA effluent can be recycled and used for landscape irrigation, cooling,
internal toilet flushing and a variety of other uses permitted under Title 22, Article 3 for
Disinfected Tertiary Recycled Water.

In August 2000, the City worked with SBSA to begin operating a pilot water recycling project
called the “First Step Project.” The First Step Project consists of temporary treatment facilities

and permanent buried pipelines that deliver recycled water to landscape customers in the
vicinity of the SBSA plant. The intent of the program is to demonstrate the feasibility of
producing recycled water at SBSA that meets California’s Title 22 Environmental Health
requirements for “Disinfected Tertiary Recycled Water,” while using it successfully in the
community, primarily for landscape irrigation. The program is designed with the intent to
provide recycled water for two to four years utilizing existing facilities with minimal modifications.
The pilot project has provided SBSA and Redwood City staff with first-hand operating
experience that is beneficial in assessing the viability of potentially expanding water recycling to
other landscape irrigation customers in the Redwood Shores area. City Council approval
allowed continuing and expanding the First Step project in 2002 and 2003, with funding
responsibilities shifting from the SBSA to Redwood City.

1.1.3      Water Recycling Feasibility Study for the Redwood Shores
           Area
To further explore the use of recycled water, the City completed the “Water Recycling Feasibility
Study for the Redwood Shores Area,” dated January 22, 2002 (prepared by Kennedy/Jenks
Consultants and herein referred to as “The Redwood Shores Feasibility Study). This report
evaluated the viability and cost of expanding water recycling to landscape irrigation customers
located in Redwood Shores as well as expanding recycled water outside Redwood Shores,
possibly in other portions of Redwood City, and the cities of Belmont, San Carlos and Foster
City. The Redwood Shores Feasibility Study quantified potential demands for landscape
irrigation and the water quality parameters required for successful long-term irrigation of existing
landscape. The Redwood Shores Feasibility Study also evaluated and recommended
appropriate interim and permanent recycled water treatment facilities at SBSA, and evaluated
the feasibility and costs of various recycled water distribution system alternatives. The facilities
recommended in the Redwood Shores Feasibility Study are:

   ●    Interim Treatment Facilities: build a new chlorine contact pipeline and convert an
        existing digester into a covered recycled water storage tank.

   ●    Permanent Treatment Facilities: build a new recycled water storage tank and recycled
        water pump station, and investigate the use of ultraviolet light, in lieu of sodium
        hypochlorite, for disinfection.

   ●    Distribution System: build an all-new recycled water distribution system in Redwood
        Shores and increase the number of recycled water customers to reduce water demands
        on the Hetch Hetchy regional water system by about 1,153 AF/yr.

The study also revealed that significant additional recycled water customers existed in other
portions of the Redwood City, and that further study of an expanded recycled water project was
warranted. Two additional geographic areas of particular interest were defined, the Greater
Bayfront area and central portions of Redwood City.


1.2        Purpose and Authorization
The primary purpose of this report is to develop a recycled water program for the City. The
information from the Redwood Shores Feasibility Study is used and refined to identify facility
requirements and costs, and perform an economic analysis of a recycled water system that
would maximize the use of recycled water in a cost-effective manner. This report also develops
a recycled water Capital Improvements Program (CIP) and creates a phased implementation
plan for Redwood Shores, the Greater Bayfront Area, and Central Redwood City. Refer to
Figure 1:. Redwood Shores is the area located east of Bayshore Highway 101, between the
Ralston Avenue and Holly Street interchanges. The Greater Bayfront Area is east of Bayshore
Highway 101 and north of Cargill’s Salt Evaporating Ponds. Central Redwood City is defined as
the principal section of Redwood City, west of Bayshore Highway 101, and generally north of
Woodside Road and east of Alameda De Las Pulgas.

All three areas are served by the City’s potable water system. However, the California Water
Service Company provides potable water service to some customers in the southwest area of



Water Recycling Feasibility Study for Redwood City                                         Page 1-4
Central Redwood City, and several other customers within the City receive water via private
groundwater wells in the study area.

This report serves as the final project deliverable for the Recycled Water Program Feasibility
Study. A separate report, the Rate and Revenue Analysis Executive Summary Report, serves
as a companion document to this Feasibility Study. Report sections 2, 3, and 4 parallel the
work performed under tasks 1, 2, and 3, described below. Section 5 presents conclusions and
recommendations for implementing a recycled water project serving Redwood Shores, the
greater Bayfront Area, and Central Redwood City.

Kennedy/Jenks Consultants is authorized to prepare this report for the City of Redwood City
under Task Order No 2 to the Agreement for Services dated July 18, 2001.


1.3        Conduct of Study
This Feasibility Study includes four primary tasks:

   ●    Task 1 – Market Assessment

   ●    Task 2 – Treatment Evaluation

   ●    Task 3 – Distribution Evaluation

   ●    Task 4 – Conclusions and Recommendations

Each task is outlined below.


1.3.1      Task 1 – Market Assessment
The Market Assessment consists of refining the recycled water market assessment for the
Greater Bayfront Area by collecting, reviewing, evaluating, and summarizing specific irrigation
and non-irrigation demand information through field reconnaissance and using information
provided by the City’s Community Development Services Department for proposed
development and re-development. Development information was collected and discussed with
the City’s Community Development Services Department and the City’s environmental
consultant. Existing and future recycled water customer locations and demands are identified
using the City’s Geographical Information System and existing aerial photography. The existing
market assessment for Redwood Shores and Central Redwood City is reused from the
aforementioned Redwood Shores Feasibility Study. The composite market assessment,
showing the relative size, customer identification number and location of customer demands in
the three areas of Redwood City being addressed under this study are then used in the
distribution system evaluation of Task 3.


1.3.2      Task 2 – Treatment Evaluation
The treatment evaluation focuses on comparing the cost and non-cost factors associated with
SBSA’s ongoing work related to evaluating alternative disinfection processes. Two alternatives
are reviewed including hypochlorite and ultraviolet light (UV) systems.




Water Recycling Feasibility Study for Redwood City                                     Page 1-5
1.3.3      Task 3 – Distribution Evaluation
The distribution system evaluation consists of evaluating the feasibility and costs of various
recycled water distribution system alternatives. Alternatives are developed based on
discussions with City and SBSA staff regarding customer selection pipeline alignment
constraints, storage and pumping site possibilities, satellite treatment, special pipeline crossing
requirements, flexibility for future expansion of the system, and opportunities to combine
construction of recycled water pipelines with other planned City projects. The costs and
benefits of the distribution system alternatives are compared and the most feasible alternatives
are analyzed further in Task 4.


1.3.4      Task 4 – Conclusions and Recommendations
Task 4 consists of making conclusions and recommendations, including the following:

   ●    A preferred system alternative is selected for subsequent financial analysis, based on an
        evaluation of the alternatives developed under Task 3. The preferred alternative meets
        specific cost effectiveness, supply, and future flexibility goals.

   ●    A recycled water capital improvement program is developed.

   ●    A phased implementation strategy is recommended.

Section 2: Market Assessment


2.1        Customer Prioritization
The prior Redwood Shores Feasibility Study developed several priority classifications for
potential customers in the Redwood Shores. Because the area under study in this report is
larger, and has different geographical and customer characteristics, the previous priority
classifications are modified. The customer priority classifications for this Study are defined as
follows:

Priority 1 Customers:

   ●   Existing First Step Project customers

   ●   Customers with agreements in place for service

   ●   Potential customers or groups of customers that have relatively large demands, and are
       adjacent to potential transmission pipeline corridors

Priority 2 Customers:

   ●   Potential customers or groups of customers that have small to medium-sized demands,
       and are adjacent to or relatively near potential transmission pipeline corridors

Priority 3 Customers:

   ●   Potential customers or groups of customers with relatively small demands, that are
       either remote from potential transmission pipeline corridors, or may have higher
       customer site retrofit costs

   ●   Proposed future developments or re-development sites, or existing customer sites that
       are served by private wells or the California Water Service Company

Priority 4 Customers:

   ●   Landscaped sites that are not presently irrigated or other uses that have very low
       demands

   ●   Sites that are very remote from potential transmission pipeline corridors, require
       significant additional pumping because of site elevation, or appear to have very
       challenging/expensive customer site retrofit costs

The feasibility of serving Priority 1 – 3 customers recycled water varies depending on customer
location and site demand. Priority 1 and 2 customers represent the most viable customers that
are ready to be served, if the City implements a mandatory use ordinance or obtains an
agreement for service. The annual recycled water demand from Priority 1 and 2 customers
represents the most reasonable minimum estimate of potential “new water supply” for integrated
water supply planning. Some portion of Priority 3 customer demands appear they could be




Water Recycling Feasibility Study for Redwood City                                          Page 2-1
cost-effectively served, however, service in many cases is dependent upon establishing
institutional agreements to replace a current water supplier or future development/
redevelopment activities. Serving Priority 4 customers with recycled water does not appear cost
effective or viable for a variety of reasons, and therefore their demands do not appear to be a
source of “new water supply” for the City.

Detailed information regarding every potential customer is presented in Appendix A, and the
customers are grouped by their respective geographical service area.


2.2        Sub-Regional Project Market Considerations
Redwood City is currently the sole retailer of recycled water produced by SBSA, which is a joint
powers authority between the Cities of Redwood City, Belmont and San Carlos. All of the other
agencies participating in SBSA have the authority to make beneficial use of recycled water from
SBSA; however, their geographical location (west of Bayshore Highway 101) would require
pipelines be constructed through Redwood City (Redwood Shores).

Because the City of Belmont and San Carlos may wish to develop their own recycled water
projects in the future, a rough estimate of their potential recycled water demands was made
during the prior Redwood Shores Feasibility Study. Their landscape demands could range from
300 to 800 AF/yr, however 300 to 500 AF/yr would appear to be the most cost-effective and
viable market that could be served. Extending service to either or both of these cities would
require pipeline capacity from SBSA through Redwood Shores and across Bayshore Highway
101. The Redwood City Council has expressed concerns about minimizing pipeline
construction impacts to citizens within the Redwood Shores area, and therefore, the flexibility to
serve Belmont and San Carlos demands will be considered during the development of
alternatives under this study. It is suggested that the City and SBSA contact representatives at
Belmont and San Carlos to discuss their interest in using recycled water and/or participating in a
joint project. (Note that the Belmont Sports Complex (Priority 3 customer) is the only major
customer located on the east side of Highway 101.)

Foster City is located north of Redwood Shores, east of Bayshore Highway 101. Although
Foster City is not part of the SBSA joint powers authority, its proximity to SBSA and apparent
significant market for recycled water makes it a potentially viable candidate for a joint project,
especially if some type of water transfer arrangement could be established between Foster City
and Redwood City (Hetch Hetchy water for recycled water). Based on the prior Redwood
Shores Feasibility Study, Foster City appears to have at least twice the overall landscape
irrigation demand of that in Redwood Shores (up to 2,000 AF/yr). A cursory evaluation showed
that it appears a pipeline could be extended from SBSA directly to Foster City using trenchless
construction methods to cross the Steinberger Slough. Implementing a recycled water project
with Foster City would require a separate distribution system form the one proposed in the
Redwood Shores, and an institutional arrangement between Redwood City, SBSA and Foster
City.


2.3        Regional Project Market Considerations
Over the long-term, a larger regional project is being explored under the San Francisco Bay
Area Regional Water Recycling Program (BARWRP). Under this concept, recycled water



Water Recycling Feasibility Study for Redwood City                                        Page 2-2
systems may be interconnected to serve a broader regional area and help address ecologic
health and improve water management associated with the Bay-Delta system under CALFED.
The viability of implementing this concept is not well-defined at this time, and facility capacity for
a larger regional project of unknown size is not considered under this study.


2.4        Recycled Water Uses
There are a number of viable uses for recycled water that can be considered for the Redwood
City Recycled Water Project. The recycled water quality produced at SBSA meets the
requirements under California Code of Regulations, Title 22, for Disinfected Tertiary Recycled
Water. The California State Department of Health Services (DHS) supports recycled water use
for the following applications at a minimum.


2.4.1      Landscape Irrigation
Landscape irrigation represents the largest potential market for this project. Annual recycled
water demands for landscape irrigation customers are developed using information from several
sources including:

   3. Redwood City’s historical water meter information. The meter information for the year
      2000 is considered an “average” year, based on measured precipitation versus historical
      averages.

        a. Landscape meters; type # 5 – common area irrigation and type #9 – residential
           irrigation

        b. Mixed Use meters; types # 3 - commercial, type #7 - City facilities, type #8 -
           institutional (schools and churches). John Whitcomb, a consultant to the City,
           provided a methodology to separate indoor use from outdoor use for combined
           meters. Annual indoor use is calculated as (average winter monthly demand) x 12
           months. The indoor use is then subtracted from the total use to estimate the outdoor
           use.

   4. Theoretical water demands were also calculated under the prior Redwood Shores
      Feasibility Study for selected sites using the turf/ornamental area (sq. ft.) determined by
      planimetering aerial photography and replacement evapotranspiration (Eto) criteria.

   5. In instances where no other current information was available, data from the Redwood
      City Recycled Water Master Plan prepared by CH2M Hill in 1991 (herein referred to as
      “Recycled Water Master Plan”) was reviewed.

Peak irrigation demands are calculated using the peaking criteria developed under the
Redwood Shores Feasibility Study. Irrigation is assumed to occur during night hours, although
some irrigation may occur during the day, when attended by landscape maintenance personnel.


2.4.2      Industrial Uses
Annual demands for industrial uses were taken from information including City meter data for
type # 4 meters, City correspondence with customer representatives, or other available



Water Recycling Feasibility Study for Redwood City                                           Page 2-3
information. Most of the current or proposed industrial use are in the Greater Bayfront area and
are for sand washing, concrete batching, and recycling related uses.


2.4.3      Environmental Water
The only environmental use for recycled water considered under this study is the pond adjacent
to SBSA’s facilities. The annual demand for this use is not included in the distribution system
evaluation because it is served directly via SBSA. Water for the environmental restoration of
Cargill’s Salt Ponds south of Seaport Blvd. is not included as a demand, as Cargill indicated
these ponds will not be a part of with the 16,500 acres of ponds around the bay that are being
sold to environmental groups and state agencies for future protected wetlands (ref: San Jose
Mercury News 5/29/02).


2.4.4      Cooling Water
Although industrial cooling is a viable use, and some cooling customers are expected to be
served over the long term, no specific customers have been identified at this time. Cooling
demands appear to provide relatively small opportunities in Redwood City, and would be day
uses that could use available system capacity when landscapes are not being irrigated.


2.4.5      Future Indoor Uses
The potential for serving indoor uses (toilet flushing) in the future is conceivable for
commercial/office/multifamily sites that are either being developed or re-developed. Indoor
demand criteria were provided by John Whitcomb and taken from the Uniform Plumbing Code
(UPC). It is assumed that the City could mandate indoor use on a District-by-District basis, as
the City adopts requirements under SB 2095. The criteria and assumptions for these daytime
uses include:

   1. 9.67 gallons/person/day for toilet flushing (JW)

   2. 1 person/50 sq ft./day for retail and restaurant space, 10hrs per day (24/10=2.4), 365
      days per year (UPC)

   3. 1 person/100 sf/day for office space, 8 a.m. - 6 p.m. (24/10=2.4), 22 working
      days/month, 11 months per year (UPC)

   4. 2.35 persons per dwelling unit/day (JW)

Additional site-specific assumptions are referenced in the comment column of the tables in
Appendix A.


2.4.6      Tank Truck Fill Station
Because recycled water can be readily used for construction purposed, wash down and other
City maintenance uses, it is suggested that tank truck fill stations be located at SBSA and other
convenient locations in the system as it expands. Specific demands for this use are not
included in the market assessment projections.

2.5        Market Assessment Summary
The potential recycled water supply that could be served to each of the three service areas and
priority classifications are summarized in the enclosed tables in Appendix A, titled “Recycled
Water Demand Summary”. The tables list all of the information sources and a “comment”
column describing which source of information was used. The historical information was
compared to the theoretical values, and when these were comparable, the City’s meter data
was typically used. Where large discrepancies were observed (i.e. some City Parks),
theoretical values were used, as there are instances where City staff indicate meter information
may be incomplete, or site observations appeared inconsistent with record data.

The market assessment shows that in the future recycled water demands in the City could total
up to approximately 3,238 AF/yr. Because it does not appear cost-effective to serve Priority 4
customers, the maximum potential future demand appears to be about 3,172 AF/yr. The
following table summarizes the demands for each service area, broken down by customer
priority. In addition, each customer location, identification number and site area is depicted on
Plate 1, which is located at the end of this report.

Section 3: Treatment Evaluation


3.1         Recycled Water Quality Requirements
The regulatory quality requirements for the recycled water treatment are set forth in Title 22,
Article 3. Considering the potential uses described in Section 2, recycled water will need to
meet the requirements for “Disinfected Tertiary Recycled Water”, which is also suitable for
unrestricted body contact.

The stipulations of Title 22 that apply to the treatment facilities considered under is project
include the following three areas.


3.1.1       Coagulation
Colloidal and finely divided suspended matter shall be destabilized and agglomerated upstream
from the filter by the addition of suitable floc-forming chemicals if the influent turbidity to the filter
exceeds 5 nepholometric turbidity units (NTU).


3.1.2       Filtration
The flow rate entering the filter shall not exceed 5 gallons per minute per square foot (GPM/ft²)
of filter surface area in mono, dual, or mixed media gravity filtration systems; and

The turbidity of the filtered wastewater shall not exceed any of the following:

    ●   A daily average of 2 NTU

    ●   5 NTU more than 5% of the time within a 24-hour period; and 10 NTU at any time


3.1.3       Disinfection
    ●   A chlorine disinfection process following conventional treatment or its equivalent that
        provides a CT (the product of total chlorine residual and modal contact time measured at
        the same point) value of not less than 450 milligram-minutes per liter (mg-min/L) shall be
        maintained at all times with a modal contact time of at least 90 minutes, based on peak
        flow; and

    ●   A median concentration of total coliform bacteria measured in the disinfected effluent
        does not exceed an MPN of 2.2 per 100 milliliters utilizing the bacteriological results of
        the last seven days for which analyses have been completed and the number of total
        coliform bacteria does not exceed an MPN of 23 per 100 milliliters in more than one
        sample in any 30-day period. No sample shall exceed an MPN of 240 total coliform
        bacteria per 100 milliliters.

3.2        First Step Recycled Water Project
As part of an agreement with the Regional Water Quality Control Board for expanding the
capacity of the existing treatment facilities, South Bayside System Authority (SBSA) took a
leadership role in developing a demonstration recycled water project in the Redwood Shores
area. In cooperation with the local water retailer, the City of Redwood City, SBSA initiated the
First Step Recycled Water Project and began supplying recycled water to the nearby Redwood
Shores area in the summer of 2000. SBSA had prior favorable experience producing recycled
water during the end of the last drought in the early 1990s, when recycled water was produced,
filled into tank trucks, and used for construction related purposes.

The intent of the project was to demonstrate the feasibility of producing recycled water at SBSA
that met Title 22 requirements for “Disinfected Tertiary Recycled Water”, while using it
successfully in the community, primarily for landscape irrigation. The project was designed with
the intent to provide recycled water for a two-year trail period, utilizing existing facilities to
minimize capital expenditures.


3.2.1      First Step – The First Two Years (2000-2001)
The First-Step recycled water project initially consisted of using the following “batch” mode
treatment strategy that had very low initial capital costs.

   1. Coagulant was added to the entire secondary clarifier effluent.

   2. Coagulant mixing with secondary clarifier effluent was provided using the dual media
      filter (DMF) feed pumps.

   3. Flocculation of the coagulant with suspended solids occurred in the DMF feed piping.

   4. Filtration was provided using the existing DMFs.

   5. Manual turbidity monitoring of the DMF effluent was made until the turbidity dropped
      below 2 NTU.

   6. Filtered effluent was transferred to a spare, clean aeration basin, through the use of a
      new 900 GPM production pump, until a satisfactory batch volume was stored.

   7. Disinfection of the stored batch was provided by manually adding hypochlorite to the
      aeration basin and using the existing turbine mixers to achieve mixing.

   8. The completely treated recycled water was supplied to the distribution system using a
      new supply pump constructed in the aeration gallery room.

Considering the proposed two-year horizon for the First Step Project, this batch mode treatment
strategy was found to be cost-effective. The batch process consists of treating a batch of
recycled water at a high rate over a short period at night, storing it, and then supplying the
demand by pumping from storage. For the First Step Project, recycled batches were made at
night when the flows at the plant were lowest to minimize coagulant costs. Much of the
coagulated/filtered water is not made into recycled water, due to the limited pumping capacity of



Water Recycling Feasibility Study for Redwood City                                        Page 3-2
the production pump. The additional coagulant cost was offset, however, by the small capital
investment required in new facilities. The existing capital facilities, such as dual media filters for
direct filtration and the aeration tanks for disinfection, contact and storage were all cost-
effectively used.

During the 2000 irrigation season, the supply pump station provided up to 0.13 million gallons of
recycled water per day at a minimum of 55 psi at the sprinkler heads. For the 2001 season, the
capacity was expanded to 0.24 million gallons per day, over an eight-hour irrigation period.


3.2.2      First Step – The Third and Fourth Years (2002/2003)
During 2001, the Redwood Shores Feasibility Study evaluated the feasibility and costs of
expanding water recycling to serve a much larger area of the Redwood Shores community.
Based on the results of the study, the City of Redwood City decided to continue the existing
First Step project and begin moving towards the decision to implement a larger-scale,
permanent recycled water system that might be completed by the summer irrigation season of
2004. In addition, Redwood City identified additional customers that would take recycled water
from existing distribution pipelines increasing the need for recycled water supply. At the same
time, SBSA desired to make a few modifications to the batch mode treatment system including:

   ●    Returning aeration basins back to regular intended service

   ●    Providing covered storage for finished recycled water to minimize water quality
        degradation from contact with birds and from exposure to light.

   ●    Reducing staff time and manual operations, by making recycled water on a continuous
        basis

To serve the projected increase in demands and meet SBSA’s operational needs during the
2002 and 2003 irrigation seasons, interim modifications were required at the Plant. Since a
larger-scale project appeared to be implemented by 2004, the interim project was designed with
the intent of maximizing the utilization of other available existing facilities to minimize capital
expenditures. The interim system was designed to produce at least 250,000 gallons per day
(equivalent to 175 gpm) and included the following components:

   ●    One existing DMF cell dedicated for recycled water treatment.

   ●    A new chlorine contact pipeline

   ●    Using existing Digester No. 1 for covered storage of recycled water

   ●    A new coagulant dosing pump and mixer

   ●    A new sodium hypochlorite pump

   ●    A new recycled water production pump




Water Recycling Feasibility Study for Redwood City                                           Page 3-3
Design of the interim system was completed in March 2002. Construction was subsequently
completed and the interim project had a successful startup in June 2002.


3.3          Permanent Recycled Water Treatment Improvements
Based on the results of the Redwood Shores Feasibility Study, the City initiated implementation
of a larger-scale recycled water project that would involve the design and construction of
permanent dedicated recycled water treatment facilities at SBSA. The new, permanent facilities
are currently projected to go online in the summer of 2004, and were tentatively sized for 2MGD
capacity for initiation of a Redwood Shores project. The prior study included a recommendation
that additional consideration be given to the final selection of the disinfection process. Two
alternatives were considered, a conventional system using sodium hypochlorite to achieve CT
requirements and a non-conventional system using ultraviolet light (UV) meeting the
Department of Health Services (DHS) guidelines for design of these systems.


3.3.1         Disinfection Alternatives

3.3.1.1      Sodium Hypochlorite Disinfection
SBSA currently uses hypochlorite disinfection for both regular plant operation and for recycled
water treatment. New hypochlorite storage facilities are not needed for this alternative. The
primary system component needed is a chlorine contact facility (structure or pipeline), which
allows enough contact time to meet the CT requirement of 450 milligram-minutes per liter (mg-
min/L). The other necessary equipment need for disinfection system is a dosing pump.

The same assumptions were applied in estimating the capital and O&M costs for hypochlorite
disinfection for the permanent facilities as were used during the prior study, however, based on
recent evaluations by SBSA, a concrete chlorine contact chamber has been selected in lieu of a
new pipeline, based on a variety of construction and operational considerations.

The advantages of a hypochlorite disinfection process include:

   ●      Simple installation and implementation

   ●      Low Operations & Maintenance costs

   ●      Plant operations staff familiarity with this disinfection method.

The disadvantages include slightly larger site requirements for the contact chamber and the
marginal increase in the level of dissolved salts in the recycled water from the addition of
sodium hypochlorite.

3.3.1.2      Ultraviolet Light Disinfection
UV was the preferred disinfection alternative at the time the Redwood Shores Feasibility Study
was completed. The primary reason was that it appeared to be more cost-effective, especially
for systems 2MGD or larger, and because of its modular nature relative to future expansion,




Water Recycling Feasibility Study for Redwood City                                      Page 3-4
ability to potentially treat emerging contaminants and because it did not contribute to an
increase in the dissolved salt levels in the recycled water.

Additional investigations by SBSA into UV have recently been performed. Based on
discussions with operating personnel at other wastewater treatment plants that use UV systems,
some problems were discovered. In several instances, UV manufacturers tended to
recommend units that later appeared undersized, and lamp output degradation dropped off
faster than anticipated. Thus, it was determined that the capital cost estimate for UV used
during the prior study were too low.

In addition, a significant non-cost factor was observed regarding the complexity of procuring UV
equipment. Currently, UV systems from different manufacturers are not directly comparable
because of lamp and hydraulic configuration variations, making it difficult to write a performance
specification that will allow both fair competition and evaluation among various UV
manufacturers. Furthermore, the guidelines for UV disinfection applicable to recycled water are
interpreted in different ways by different manufacturers, which have led to difficulties in
comparing the performance of one UV unit with another. Finally, the UV industry is rapidly
evolving. New manufacturers are coming forward with a variety of products and it appears the
industry will benefit from time, to let the technology and capital and operating costs settle into
consistent ranges.


3.3.2      Disinfection Alternatives Evaluation

3.3.2.1    Cost-Effectiveness Evaluation
A workshop was held at SBSA in May of 2002, with consultants and operating staff to further
review and compare the costs of hypochlorite and UV disinfection. Both capital costs and O&M
costs were evaluated. The results are presented in the following table for a design flow of
2MGD.

3.3.2.2    Selected Disinfection Process
Based on the above cost comparison, along with the aforementioned non-cost issues, SBSA
decided that the hypochlorite disinfection alternative was the most economical and preferred
option for the initial 2 MGD system. If the recycled water project expands beyond the initial
2MGD size, future consideration can be given towards UV.




Water Recycling Feasibility Study for Redwood City                                           Page 3-5
3.4        Permanent Treatment Facilities Strategy
SBSA has selected a strategy for permanent treatment that includes several components. In
addition, provisions for siting recycled water storage and pumping facilities are included at
SBSA’s site. The basic criteria for the permanent treatment system include the following:

   ●   A system designed for 2 MGD or more (nominal, to be confirmed by this study and the
       City’s selected implementation plan)

   ●   Two existing DMF cells dedicated to recycled water production, but with the flexibility to
       be used for normal plant operation as well.

   ●   Coagulant dosing and mixing at the two DMF cells

   ●   Hypochlorite dosing at a new chlorine contact chamber

   ●   New storage facilities with capacity sized for one day of storage during peak month,
       average day conditions, for operational reliability. A standby connection to the potable
       water system will also be provided at the storage tank using an approved air-gap system
       for added operational reliability.

Based on a separate evaluation prepared by Kennedy/Jenks Consultants for SBSA for flows
ranging from 2 to 6 MGD, it appears the permanent system can be configured to flow by gravity,
from the DMFs through the chlorine contact chamber to storage. Refer to Figure 2:. A size of 6
MGD was selected because it represents the nominal capacity of one bank of filters (6.25 MGD
is maximum rated capacity), and a project could be packaged for about 2 MGD increments of
expansion. Filtered water could be conveyed to the chlorine contact chamber via a new 24-inch
diameter pipeline that could be mounted on the outside of the south side of the main structure of
the treatment works. The 24-inch pipeline would provide capacity for flows up to 6 MGD and
mounting it on the structure would reduce costs and impacts of underground construction on the
site. The 30-inch diameter pipe used for the contact pipeline as part of the interim treatment
improvements could be utilized as part of this permanent pipeline, for additional cost savings, if
it is feasible at the time of construction.

The new chlorine contact chamber is proposed to be a new concrete structure mounted on the
west side of the main structure. It has been confirmed that the main structure can support the
combined weight of the new chamber and water, consequently resulting in considerable cost
savings over constructing either a contact pipeline or separate pile supports chlorine contact
chamber.

Section 4: Distribution Evaluation


4.1         Overview
The recycled water distribution system for the City is proposed to be comprised of ground level
storage reservoir(s), pumping facilities, transmission pipelines, standby connections to the
potable supply, and customer service laterals and meters. In addition, the customer’s onsite
facilities must be retrofit as required to comply with a number of regulatory requirements that
generally address preventing cross-connections between potable and recycled water facilities,
preventing over spray and runoff, and providing adequate signage for public awareness, etc.

4.2         Distribution System - Development and Screening of
            Preliminary Alternatives

4.2.1       Methodology
The preliminary distribution system alternatives are developed using an iterative approach that
considers a variety of water supply, cost-effectiveness and future flexibility factors. The City
Council has indicated a desire to preserve flexibility in sizing the systems components, so future
decisions can be made over time in the best interest of their overall water enterprise. Current
water supply projections may change over time allowing optimization of both existing and future
facilities and overall costs.

Some of the primary development and screening steps include:

   ●    Reviewing the Market Assessment information for each area relative to customer
        location, demand size, day or night demand, existing of future customer status, and
        relative complexity of site retrofit for service.

   ●    Identifying a number of possible transmission pipeline corridors to optimize the apparent
        pipeline cost vs. water supply for Priority 1, 2 and 3 customer classifications.

   ●    Performing pipeline alignment reconnaissance and meet with City staff regarding
        upcoming City projects and known pipeline corridor constraints and special jurisdictional
        crossing requirements.

   ●    Refining pipeline corridors and meeting with City staff to discuss proposed initial
        transmission pipeline alignments.

   ●    Developing preliminary service alternatives using permutations of the following variables:

        ■   Service Areas: Serve Redwood Shores only, Redwood Shores and the Greater
            Bayfront Area, or all three service areas.

        ■   Customers: Serve priority 1 and 2 customers only, or serve Priority 1, 2, and 3
            customers, relative to potential water supply benefits.




Water Recycling Feasibility Study for Redwood City                                            Page 4-1
        ■   Storage and Pumping: Examine centralized versus decentralized pumping and
            storage concepts. Siting all pumping and storage at SBSA has the benefit of
            eliminating the need to construct storage tanks and pump stations within residential
            areas of Redwood City. However, decentralized facilities were investigated to
            determine if transmission pipeline sizes could be reduced by moving storage and
            pumping facilities closer to the customers in both the Greater Bayfront Area and
            Central Redwood City. Site possibilities, both existing public and future developer
            sites were considered.

   ●    Satellite Treatment: Centralized versus decentralized treatment options were discussed
        with the City and SBSA. SBSA operates a large raw wastewater force main that exists
        along the east side of Highway 101 and passes through both the Greater Bayfront Area
        and Redwood Shores. New technologies such as the membrane bio-reactor and UV
        have been successfully used in a variety of satellite treatment applications, on relatively
        small sites and without creating an odor nuisance with adjacent land uses. The concept
        is to “skim” raw wastewater from the force main and treat it to the same water quality
        objectives described in Section 3 typically using an emerging, non-conventional
        treatment process. Solids and waste sludge from the treatment process would be re-
        routed back to the force main to avoid additional costs and potential odor control
        problems associated with handling them at the satellite plant location. A location in the
        Greater Bayfront area near the existing pump station at Maple Street was screened
        relative to providing supply to the Greater Bayfront area and Central Redwood City. The
        SBSA force main has adequate raw wastewater supply for these areas.

        The cost, environmental compliance and public acceptance considerations associated
        with developing a new satellite wastewater treatment project are significant. Smaller
        projects (~2 MGD) can have total capital costs in the range of $5-10/gallon or more for
        the design and construction of facilities, plus site acquisition and right-of way related
        costs. Based on a cursory review of the pipeline length from SBSA to the Bayfront Area
        (~5.0 miles), it does not appear that there are compelling cost benefits to satellite
        treatment. In addition to the added public, environmental and site acquisition hurdles, a
        satellite treatment project would require added operational effort remote from SBSA’s
        existing treatment site to manage the facility. Satellite treatment was screened from
        further evaluation under this study.

Eight preliminary alternatives were developed for hydraulic analysis. The eight alternatives
encompass a full range of possible system configurations, so different levels of service to the
three geographical areas and customer priority levels could be investigated. In addition, both
centralized and decentralized storage and pumping options were included to investigate the
cost-effectiveness of different system configurations. The alternatives ranged from small
systems (Priority 1 and 2 customers in Redwood Shores only) to City-wide systems (Priority 1,
2, and 3 customers in all three geographical areas) providing a range of new water supply from
just over 1,100 AF/yr up to approximately 3,172 AF/yr.


4.2.2       Hydraulic Analysis of Preliminary Alternatives
A hydraulic analysis of the distribution system alternatives is performed using the WATERCAD
computer program. The market assessment information is incorporated into a Geographical




Water Recycling Feasibility Study for Redwood City                                        Page 4-2
Information System (GIS) map and database that is used to “load” the computer model with
demand information. A separate hydraulic model is developed for each alternative using
criteria and methodology previously established in the Redwood Shores Feasibility Study. The
model output includes proposed transmission and distribution pipeline sizes, system pressures
and pumping (head) facility requirements. The design criteria and assumptions for the hydraulic
model are as follows:

   1. Minimum pressure (Pmin) in the recycled water system of 60 psi at any node under peak
      hour demand conditions.

   2. Internal pipeline diameters and friction coefficient for PVC pipe are used to model the
      system. A Hazen-Williams Coefficient of 150 is used.

   3. Maximum pressure (Pmax) in the recycled water system is about 100 psi.

   4. Maximum velocity (Vmax) in the recycled water system is about 10 ft/sec.

   5. Steady state analysis varying the HGL at the storage tanks to maintain the Pmin and
      Pmax pressures.

   6. Daytime demands and nighttime demands are modeled separately, and nighttime
      demands associated with landscape irrigation control facilities sizing both now and in the
      future.

4.2.2.1      Demand Factors and Computer Model
Demand terminology and peak demand conditions used for hydraulic evaluation are
summarized below.

   ●      Average Annual Demand (AAD) - represents the annual irrigation demand during a
          year with average climate conditions and is typically measured in units of 100 cubic feet
          (CCF) or acre-feet per year (AF/yr).

   ●      Maximum Month, Average Day Demand (MMAD) – represents the average daily
          demand during the peak irrigating months during years having average rainfall. The
          MMAD demand is used to size both the needed treatment capacity and the recycled
          water storage requirements, and uses peaking factors developed from recent historical
          irrigation data (MMAD = ADD x 12/8 x 1.6). The MMAD demand represents the
          expected sustainable demand reduction during peak irrigating months on the Hetch
          Hetchy potable supply.

   ●      Maximum Month, Peak Day Demand (MMPD) – represents the largest daily demand
          expected during any day of the peak irrigating months of years when rainfall is well
          below average (drought). This demand is estimated using a peak factor used in other
          Bay area recycled water projects. (MMPD = MMAD x 1.5)

   ●      Peak Hour Demand (PH) - represents the instantaneous maximum flow rate required.
          For night time irrigation uses under the MMPD demand, this assumes a 9-hour irrigation
          period between 9 p.m. and 6 a.m. The MMPH demand is a conservative estimate and is
          typically expressed in gallons per minute (gpm). The peak hour demand is used to




Water Recycling Feasibility Study for Redwood City                                         Page 4-3
          establish the pressure and capacity requirements of pumping and pipeline facilities.
          (MMPH = MMPD x 24/9)


4.2.3        Sizing Pipelines, Storage, Pumping, and Standby Connections

4.2.3.1      Pipelines
Pipelines are sized using the Peak Hour demand. Pipelines must be large enough to convey
water without exceeding pressure and velocity criteria.

4.2.3.2      Storage Tanks
Storage will be provided following treatment and disinfection to provide operational flexibility and
reliability for the treatment facilities and distribution system. Storage tank capacity is set equal
to a one day supply of recycled water at the Maximum Month, Average Day demand condition.
The storage volume will be used on a daily basis to supplement treatment capacity as required
to meet the difference between the peak day and peak hour demands.

4.2.3.3      Pumping
Pumping facilities are envisioned to consist of four dedicated pumps, one standby pump,
mechanical piping, an electrical service and a motor control center. The pumping facilities at
SBSA will be located either outside on a concrete slab or enclosed within existing structures. If
pump stations are located off of the SBSA site, it is anticipated that they would require
dedicated building enclosures for aesthetic purposes. Motor drives are anticipated to be
variable frequency drives and the pumps will be controlled based on system pressure.

Pump capacity (head) requirements are determined by the hydraulic model and flow
requirements by the market assessment and peaking factors. Pumping capacity requirements
vary significantly, depending upon whether centralized or decentralized storage is considered.

4.2.3.4      Standby Potable Water Connections
Standby connections are suggested to further enhance reliability in the event the recycled water
supply is interrupted. Where storage tanks are located, a pipeline is constructed between the
nearest medium or large sized potable water pipeline and the recycled water storage tank.
Additionally, in each service area, an in-system potable water standby connection (backflow
preventer with removable spool piece) could be provided in the recycled water system to
achieve a relatively simple potable water backup during if the treatment plant or pump station
were to have a system failure.


4.2.4        Preliminary Alternatives Evaluation

4.2.4.1      Hydraulic Modeling Results
Early in the modeling process, it became apparent through iterations of modeling and cost
evaluations, that there were no apparent cost benefits associated with decentralized storage. A
pump station located at SBSA can provide adequate pressure to serve all lower lying elevations




Water Recycling Feasibility Study for Redwood City                                         Page 4-4
in the entire Redwood Shores and Greater Bayfront areas, and in Central Redwood City up to
approximately the Alameda De Las Pulgas. This “pressure zone” closely mimics the City’s
existing potable water system configuration. Serving any customer above the Alameda would
require booster pumping to meet service requirements. This could be provided at the customer
site or at another central location along the transmission pipeline alignment.

4.2.4.2      Cost Effectiveness Comparison of Preliminary Alternatives
Preliminary estimates of capital costs and cost effectiveness (cost per acre-foot of water
delivered) were developed for the eight preliminary alternatives based on pipeline sizes and
lengths, storage and pumping capacity, treatment costs, and standby connections. The cost
effectiveness of the alternatives ranged from $14,300/AF to $27,600/AF. The conclusions
drawn from the preliminary alternatives analysis are as follows:

   ●      The most cost-effective preliminary alternative is a “Redwood Shores only” project,
          serving Priority 1 and 2 customers. The recycled water supply for this alternative
          (1180AF/yr) is adequate to address the City’s current supply deficiencies, but does not
          provide operating flexibility for droughts under current conditions or supply for projected
          future water demands.

   ●      The cost effectiveness of City-wide alternatives that serve only Priority 1 and 2
          customers tends to be much lower than for alternatives that include Priority 3 customers.
          When the Priority 3 customers are added to City-wide distribution systems, the cost-
          effectiveness increases by about 35%. This is because Priority 3 customers make up a
          large percentage of total potential recycled water demand outside the Redwood Shores,
          and the transmission pipeline system becomes more cost-efficient when the Priority 3
          customer demands are included.

   ●      Preliminary alternatives with centralized storage and pumping at SBSA are more cost
          effective than the alternatives with decentralized storage and pumping. The cost
          required for decentralized pump stations is greater than the cost savings realized by
          reduced pipeline sizes in the transmission system.

   ●      In an attempt to improve cost-effectiveness of a City-wide project while maintaining a
          substantial recycled water supply, fine-tuning was performed by eliminating distribution
          pipelines to customers that appeared to be relatively expensive on a cost per AF/yr
          delivered basis. A slight improvement in cost effectiveness was realized in this fine-
          tuning.


4.3          Final Alternatives Development
Based on the results of the preliminary alternatives evaluation, final alternatives were developed
to meet the range of the City’s projected water supply needs, while providing the best value and
preserving flexibility for future system growth and expansion. All of the final alternatives
included some level of service to Priority 3 customers. Four basic alternatives were developed,
one of which was further evaluated as three separate sub-alternatives.




Water Recycling Feasibility Study for Redwood City                                           Page 4-5
Final Alternatives A through D are summarized in Table 3: and in Figures 4 through 9. Some
variations of Alternative C were evaluated with respect to cost-effectiveness of various service
refinements as described on Figures 6 through 8.

To preserve flexibility for future expansion of the recycled water system, the transmission
pipelines are sized under each final alternative to serve all of the Priority 1, 2, and 3 customers
in each of the three geographical areas (as in Alternative B). The cost associated with the
investment in pipeline capacity for future flexibility is identified in Section 5.

Figure 3: is a graph depicting the projected range of water supply deficit from the City’s water
supply planning efforts versus the projected recycled water supply of each final alternative over
time. It is important to recognize that the range of water supply deficit is derived from an
average climate year, when the City’s full Hetch Hetchy supply assurance is available. There
will be drought cycles in the future, and depending upon the severity and duration of these

4.3.1      Alternative A
Goal: Provide a low cost system supplying all of Redwood Shores with recycled water, while
maintaining maximum flexibility for system expansion into other areas of Redwood City,
Belmont, or San Carlos.

System Description: Alternative A provides 1,246 AF/yr of recycled water, distributed to priority
1, 2, and 3 customers in Redwood Shores only. The pipelines, however, are sized to carry up
to 3,172 AF/yr (the entire demand for all three service areas), which allows expansion of the
system without parallel pipeline construction from SBSA through Redwood Shores to Bayshore
Highway 101. All pumping and storage is located at SBSA. See Figure 4: for a schematic of
Alternative A.


4.3.2      Alternative B
Goal: Maximize the use of recycled water City-wide, by providing service to all potential
customers in Redwood City, including those not currently receiving City service, while
minimizing facilities construction costs.

System Description: Alternative B provides 3,172 AF/yr of recycled water, with service to
Priority 1, 2, and 3 customers in all three service areas. All storage is located at SBSA.
Pumping is provided at SBSA, with a booster pump station located in the vicinity of Red Morton
Park (Central Redwood City). Unused daytime capacity in transmission facilities could be used
to provide service to Belmont and/or San Carlos, but these Cities would need to provide remote
storage in their service area. See Figure 5: for a schematic of Alternative B.


4.3.3      Alternative C
Goal: The most cost effective City-wide system that maximizes supply to the extent possible.
This alternative could provide enough recycled water to eliminate the projected water supply
demand deficit during non-drought years, assuming passive conservation is achieved, while
excluding all potential customers who do not currently receive water from the Redwood City
water system.

System Description: Alternative C provides approximately 2,580 AF/yr of recycled water, with
service to most priority 1, 2, and 3 customers in all three service areas. All storage is located at
SBSA. Pumping is located at SBSA, with a booster pump station located in the vicinity of Red
Morton Park. See Figure 6: for a schematic of Alternative C. This alternative provides future
flexibility (roughly 592 AF/yr = 3172 – 2580) for serving additional city customers, or for Belmont
and San Carlos.

The cost effectiveness of Alternative C was further investigated under two sub alternatives.


4.3.4      Alternative C.1
Goal: Provide enough recycled water to eliminate the projected water supply demand deficit
during non-drought years, assuming passive conservation is implemented, but reduce capital
costs of Alternative C by eliminating the booster pump station in the vicinity of Red Morton Park



Water Recycling Feasibility Study for Redwood City                                        Page 4-14
and all customers at higher elevations. Some customers who do not currently receive water
from the Redwood City water system, but have a commitment for future service from the City
(Pacific Shores), are included.

System Description: Alternative C.1 provides approximately 2,586 AF/yr of recycled water, with
service to most priority 1, 2, and 3 customers in all three service areas. All storage is located at
SBSA. All pumping is located at SBSA. See Figure 7: for a schematic of Alternative C.1. This
alternative provides future flexibility (roughly 586 AF/yr) for either expanded City use, or for
Belmont and San Carlos.


4.3.5      Alternative C.2
Goal: Provide enough recycled water to eliminate the projected water supply demand deficit
during non-drought years, assuming passive conservation is implemented, but reduce capital
costs of Alternative C by eliminating the booster pump station in vicinity of Red Morton Park and
customers at higher elevations. Potential customers (including Pacific Shores) who do not
currently receive water from the Redwood City water system are excluded.

System Description: Alternative C.2 provides approximately 2,519 AF/yr of recycled water, with
service to most priority 1, 2, and 3 customers in all three service areas. All storage and
pumping is provided at SBSA. See Figure 8: for a schematic of Alternative C.2. This alternative
provides future flexibility (approximately 653 AF/yr) for either expanded City use, or for Belmont
and San Carlos.


4.3.6      Alternative D
Goal: Define the most cost effective system that provides enough recycled water to eliminate
the water supply demand deficit during non-drought years, assuming passive and active
conservation are achieved, while excluding those customers who do not currently receive water
from the Redwood City water system.

System Description: Alternative D provides approximately 1,955 AF/yr of recycled water, with
service to most priority 1, 2, and 3 customers in Redwood Shores and the Greater Bayfront
Area. All pipelines and customers in Central Redwood City, east of highway 101 are eliminated.
See Figure 9: for a schematic of Alternative D. This alternative provides future flexibility
(approximately 1,217 AF/yr) for expanded use within the City, or for Belmont and San Carlos.

4.4        Recycled Water System - Estimates of Probable Capital
           Costs
A detailed estimate of probable capital costs for each of the final alternatives described in
Section 4.3 are developed based upon construction cost models derived from other recent Bay
Area recycled water projects. Some of the criteria and assumptions that were used to develop
the estimates of probable costs include:

   ●   Cost for treatment facilities are based on preliminary design-level cost estimates for
       SBSA improvements.

   ●   Cost for new storage tanks with deep foundations are estimated at $1.50/gallon.

   ●   Capital costs for all pump stations were estimated from a pump station price model that
       includes factors for enclosure type, motor drive type, standby pumping and other factors.

   ●   Cost for “new pipe” alternative distribution pipelines were estimated at $12/diameter-inch
       per lineal foot for pipelines in paved areas and $9/diameter-inch per lineal foot in non-
       paved areas.

   ●   Cost for “special crossings,” such as jacking and boring under CalTrans roads or Hetch
       Hetchy crossings, are estimated at $20/diameter-inch per lineal foot.

   ●   Costs for typical service laterals/meter connections and customer retrofits city-wide are
       estimated as a percentage of the total facilities cost (10 to 15%). Experience shows it is
       difficult to estimate individual retrofit costs due to the wide variation of site conditions and
       customer requirements. Redwood Shores appears to have the most complex retrofit
       requirements (10 to15% of total facilities cost) because many users are homeowners
       associations with multiple connections. The customers in the Greater Bayfront and
       Central Redwood City areas appear to be less complex (5 to 10% of total facilities cost)
       and many of there future customers will have no retrofit costs.

Actual construction costs will vary, and are dependent on labor and material costs, competitive
market conditions and the implementation schedule that exist at the time of construction.

See Appendix B for comprehensive cost estimate information. Table 4: and Figure 10:
summarize estimated capital costs, water supply, yield, and cost/yield ratio for each alternative.

Section 5: Conclusions and Recommendations


5.1        Recommended Project
Based on an evaluation of cost-effectiveness, water supply, and future flexibility considerations,
Alternative D is recommended to the City for use in project planning and implementation,
determining a financing strategy, and in developing an initial rate and revenue plan. The
primary reason for recommending Alternative D is that it is the most cost-effective project
configuration that provides an adequate water supply (1955 AF/yr) to:

   1. reduce existing demands on the Hetch Hetchy supply to be within the City’s Supply
      Assurance contract with the San Francisco Public Utilities Commission (PUC).

   2. provide a future source of water supply for potential new developments within the City.

Alternative D also provides significant flexibility for the future, so the City can continue to explore
the benefits and cost of additional water conservation measures, overall water supply reliability
and drought tolerance issues, water transfers and other water supply management options. If
the City requires additional recycled water supply in the future, the pipelines provided in
Alternative D are oversized to allow the system to expand into the maximum, city-wide project of
Alternative B.

The total estimate of probable capital cost, including facilities construction, service connections
and site retrofit, engineering, construction management, administration and a 20% project
contingency is approximately $ 36,819,000. The portion of this cost associated with providing
oversized pipelines for future flexibility is approximately $4,891,000.

There are a number of other considerations and benefits in several key areas that are further
summarized as follows:

City Water Supply

   ●   Alternative D provides a new water supply (1,955 AF/yr) that can meet the projected
       water supply deficit during non-drought years in the year 2020, assuming both passive
       and active water conservation is achieved. Based on recent discussions with Mr. John
       Whitcomb, consultant to the City, the current estimate of active water conservation is
       conservative, and additional water conservation can likely be achieved through the use
       of agency sponsored programs, such as rebates and direct install type retrofits for fixture
       replacement. These programs are being used successfully elsewhere in the Bay area.
       With the City’s continued commitment to water conservation, the projected reduction in
       water demand from passive and active water conservation appears it can be readily
       achieved.

   ●   The City can rapidly move towards implementing the portion of this project in the
       Redwood Shores area, and with a full commitment to customer outreach and site retrofit
       coordination, the City can re-establish water use within the Supply Assurance on the
       Hetch Hetchy regional system by 2006/2007. Rapid implementation reduces the risk of




Water Recycling Feasibility Study for Redwood City                                            Page 5-1
       being impacted by a potential drought, which would result in significant curtailments of
       water supply and the likely loss of public and private landscape investments, especially
       in the Redwood Shores area.

   ●   Alternative D does not list the existing Pacific Shores Development as a customer;
       however, transmission pipelines will extend to the site boundary. Pacific Shores’
       landscapes are currently served by groundwater wells that may be subject to future
       saltwater intrusion; therefore, they may not be a viable long-term source of water supply.
       Adequate capacity is included in the pipeline sizing under Alternative D to serve Pacific
       Shores’ projected landscape irrigation demand of 81 AF/yr. The City has committed to
       serving Pacific Shores in the future, if water service is requested, and this alternative
       provides the flexibility to meet this potential future commitment.

   ●   The system has the flexibility of conveying an additional 1,217 AF/yr or more of water
       supply in the future. There are a number of factors that the City will continue to explore
       in the future including the planning horizon beyond 2020, drought tolerance and system
       reliability issues, and other unknown factors that could result in additional water supply
       needs over time. It is possible that water could be needed for cooling a power
       generator, or other unknown industrial demand associated with the Port of Redwood
       City, or a redevelopment or new housing project that is currently not planned elsewhere
       in the City.

   ●   In general, having recycled water in the City’s portfolio of water supply management
       tools significantly increases the reliability of the system and the ability to protect
       important investments in both public and private landscaping throughout the City, in the
       event of a drought. Potable water, recycled water and water conservation all help to
       provide a solid foundation for a water enterprise, and all three components contribute to
       improved long-term sustainability and reliability.

   Cost-Effectiveness

   ●   The relative cost effectiveness of Alternative D is slightly better than the Redwood
       Shores (only) project under Alternative A. The City can base financial planning on the
       capital cost of Alternative D, but still preserve the flexibility to downsize portions of the
       transmission system in the future, if it becomes apparent that water conservation
       measures are more effective than anticipated, or new water sources or transfers become
       viable that provide a more cost-effective means of meeting total water supply and
       reliability needs.

   ●   The operating costs associated with Alternative D are comparatively very low with other
       projects in the Bay area, because most of the treatment facilities that are needed to
       produce recycled water already exist at SBSA, chemical and energy costs are
       minimized, and capable wastewater and water operating staff already exists at SBSA
       and the City.

System Configuration

   ●   The proposed Alternative D can be completely implemented in low lying areas on the
       east side of Highway 101 and can be completely operated in one pressure zone. All



Water Recycling Feasibility Study for Redwood City                                         Page 5-2
       treatment storage and pumping facilities can be cost-effectively located on SBSA’s site,
       and adequate space exists on the site for the proposed facilities. A centralized facility at
       SBSA eliminates the need for the City to procure new sites for facilities and potential
       public and environmental concerns.

   ●   The Highway 101 Bike Path Pipeline is being constructed by CalTrans in the 2002/2003
       timeframe providing an excellent and cost-effective opportunity to prepare for serving the
       Greater Bayfront area and significant future demands associated with proposed
       developments like the Glenborough-Palls development. By the end of 2004 or any date
       thereafter, the City could have a “Recycled Water for Sale” sign posted at the Whipple
       Avenue interchange with Highway 101 for extension to any new Bayfront Area
       development or industrial use.

Construction Impacts

   ●   Because of the flexibility incorporated into the transmission system through the
       Redwood Shores area, the citizens of this community will not be subject to a second
       phase of construction. Following construction of the transmission system, no future work
       is anticipated in the parkways or roadways outside of individual developments.

Joint Project Opportunities

   ●   The City can preserve the flexibility to explore joint project opportunities with many
       potential partners including Cal Water, Belmont and San Carlos. It is recommended the
       City initiate discussions with these entities as the project moves forward into preliminary
       design to assess possibilities, constraints and benefits to all parties. Alternative D has
       adequate capacity to convey an additional 1,217 AF/yr or more through the Redwood
       Shores area for any end user. Based on the cursory market assessment prepared
       during the Redwood Shores Feasibility Study, it appears that the Belmont and San
       Carlos areas could have a combined viable market for recycled water ranging from 300
       to 500 AF/yr (800 AF/yr max.). These Cities or there water supply entity (California
       Water Services Company) could make a capacity “buy-in” to the Redwood Shores
       transmission system. Other projects in California have effectively done this, where the
       cost varies, depending on whether the participating agency bought and paid for capacity
       at the time of construction, or later after the project was implemented. There is usually a
       cost incentive for early participation that is beneficial to both parties.


5.2        Phased Implementation Strategy
The basic implementation strategy for Alternative D is summarized in Table 5:. The
implementation concept is to simultaneously build backbone infrastructure facilities such as
treatment, pumping, storage and transmission pipelines, while aggressively preparing in detail
for customer connections and site retrofit. Based on the experiences of other Bay area projects,
customer coordination and site retrofit requirements are typically underestimated, and actual
recycled water use has fallen well-behind original projections.

The proposed project could be implemented in multiple phases. Treatment, storage, pumping,
and pipeline transmission facilities to serve the Redwood Shores could be constructed in fiscal

year (FY) 2003/2004, and customer services and site retrofits could be constructed over a
three-year period between 2003 and 2006, so full supply benefits are obtained during the 2007
irrigating season. The Greater Bayfront project may be driven by future developer schedules,
but is tentatively planned so a “Recycled Water For Sale” sign could be in place at the Whipple
Avenue/Highway 101 Interchange by the year 2006, and the entire Greater Bayfront area
served by 2009. In this manner the entire Alternative D project could be in place by 2009, which
may be advantageous relative to the City having a better understanding of water supply needs
for the re-negotiation of the Water Supply Assurance with the San Francisco PUC for the Hetch
Hetchy regional water supply, slated for 2009/2010.

Assumptions
1. Outdoor Use:
   For meter types #3, #7, and #8 outdoor irrigation demand is assumed to be Total CCF for year 2000 minus indoor water use. Indoor use= Feb & March use * 6 (From John Whitcomb's Estimate from Redwood Shores)
   For meter type #5, irrigation demand is assumed to be year 2000 total.
2. Data from CH2MHill Master Plan Final Report dated August 1999.
3. The irrigation acres were determined from aerial photography and used to calculate the theorectical demand for wet, average and dry years.
4. Information provided to us by Manny Rosas via email on April 25, 2002. Demands are from year 2001. Used 81 AF/yr irrigation demand from EIR dated March 1995 by Recon Environmental Corp.
5. Demand information from RMC Pacific Materials letter to Jon Lynch dated December 7, 2001.
6. The irrigation acres were determined from aerial photography and used to calculate the theorectical demand for wet, average and dry years.
   Half of the calculated acres were used in the calculation since portion of the interchanges does not require irrigation.
7. Assumed 1 person/100 SF for Office; 1 person/50 SF for retail and restaurant; average 2.35 person/DU and 9.6 gallons/person/day.

Assumptions
1. Outdoor Use:
    For meter types #3, #7, and #8 outdoor irrigation demand is assumed to be Total CCF for year 2000 minus indoor water use. Indoor use= Feb & March use * 6 (From John Whitcomb's Estimate from Redwood Shores)
    For meter type #5, irrigation demand is assumed to be year 2000 total.
2. Data from CH2MHill Master Plan Final Report dated August 1999.
3. The irrigation acres were determined from aerial photography and used to calculate the theorectical demand for wet, average and dry years.
4. Information provided to us by Manny Rosas via email on April 25, 2002. Demands are from year 2001. Used 81 AF/yr irrigation demand from EIR dated March 1995 by Recon Environmental Corp.
5. Demand information from RMC Pacific Materials letter to Jon Lynch dated December 7, 2001.
6. The irrigation acres were determined from aerial photography and used to calculate the theorectical demand for wet, average and dry years.
    Half of the calculated acres were used in the calculation since portion of the interchanges does not require irrigation.
7. Assumed 1 person/100 SF for Office; 1 person/50 SF for retail and restaurant; average 2.35 person/DU and 9.6 gallons/person/day.
