Executive Summary
The City of El Paso realized in the late 1980s that its existing
water supply was declining at an alarming rate and that supply
would not be sufficient to meet its current population water
needs, much less satisfy its rapidly increasing population. To
address the current ground water decline problem and assure
that a sustainable water supply for the future could be found, El
Paso and its surrounding neighbors concerned about water
supply in southern New Mexico and west Texas created the New
Mexico – Texas Water Commission (Commission). The
Commission embarked on a series of evaluations, under the
primary heading of the El Paso - Las Cruces Regional
Sustainable Water Project, to determine the most feasible way of
providing a sustainable water supply not only to El Paso but also
to its neighbors to the north, in northern and southern Dona Ana
County.
The overall sustainable water supply project was divided into a
number of water supply alternatives that are composed of major
improvement components, including water treatment plants for
Hatch, Las Cruces, and Anthony, New Mexico, and El Paso,
Texas; the El Paso Upper Valley Water Treatment Plant; the El
Paso Aqueduct; and the Northeast El Paso Aquifer Storage and
Recovery System. Conceptual design packages were prepared
for each project component, describing the scope of actual
construction product for that component, the magnitude of
product required, land requirements, and estimated construction
costs.
I
The primary focus of this technical memorandum is to evaluate
the overall construction project’s physical and time constraints,
determine reasonable construction packaging and scheduling as
consistent as possible with local workforce constituents, estimate
actual construction labor requirements on a monthly basis, and
characterize the physical requirements of construction as they
relate to rights of way, environmental surface exposure, fuel
storage, staging, and other construction related activities.
II
Introduction
Objectives
The goal of this technical memorandum is to document all construction phase activities for the Phase 1
Alternative Components of the El Paso – Las Cruces Regional Sustainable Water Project under the
authority of the El Paso Water Utilities (EPWU). This work is in support of the National Environment
and Policy Act (NEPA) process, which is currently underway in connection with the El Paso – Las
Cruces Regional Sustainable Water Project.

Construction Schedule for Identified
Improvements for New Mexico Entities
General Description of the System
The identified Phase 1 needs for New Mexico entity water supply improvements include providing 3.5
million gallons per day (mgd) of treated water to municipal water entities in Rincon Valley, 20 mgd of
treated water to municipal water entities in north and central Mesilla Valley, and 4.0 mgd of treated
water to municipal water entities in southern Mesilla Valley. To provide this water will require the
construction of three new water treatment plants and associated distribution pipelines. This section
describes the Phase 1 water treatment and delivery facilities needed and provides construction details for
their construction.
Hatch Area Water Treatment Plant
The Hatch Area (North Planning Area) Water Treatment Plant will be located near the community of
Hatch in the Rincon Valley. Phase 1 construction for this plant will provide a total treatment capacity of
3.5 mgd with the capability for later expansion to 4.5 mgd capacity. The treatment plant will initially
service the communities of Hatch, Rincon, and Spaceport in Phase 1, but will eventually service the
communities of Salem and Garfield as well.
Raw water will be either diverted to the plant directly from a new diversion facility at the Rio Grande or
through the existing Rio Grande Project canal system with initial diversion from the river at Percha Dam
and delivery to the Hatch Area Water Treatment Plant from the Hatch Canal. No enlargement of the
canal system would be necessary, but substantial non-irrigation season conveyance losses may occur due
to evaporation and seepage. Due to these potential losses, this study assumes raw water will be diverted
directly from the Rio Grande to the treatment plant rather than delivered through the existing canal
system. The Hatch Area Water Treatment plant will receive the delivered raw water into a series of
storage/sedimentation ponds for settling of suspended solids. The water will then be pumped through a
membrane treatment process and passed through a granular activated carbon (GAC) filter. Chlorination
will complete the treatment process to achieve Safe Drinking Water Act (SDWA) standards for finished
drinking water.
Two conveyance pipelines will distribute treated water from the Hatch Area Water Treatment Plant to
the communities of Hatch, Rincon, Spaceport, and eventually to Salem and Garfield. A 14-inch
diameter pipeline will convey treated water 4.0 miles to the communities of Rincon and Spaceport. A
10-inch diameter pipeline will convey treated water 1.9 miles to Hatch. In a later phase, an 8-inch
pipeline will extend from the 10-inch Hatch pipeline terminus another 4.8 miles to Salem and Garfield.
As a part of Phase 1, two treated water pump stations will be located at the Hatch Area Water Treatment
Plant site. The North Pump Station will provide pressure for the transmission line to Hatch and
eventually to Salem and Garfield. The South Pump Station will provide pressure for transmission to
Rincon and Spaceport.
3
Las Cruces Area Water Treatment Plant
The Las Cruces Area (Central Planning Area) Water Treatment Plant will be located near Las Cruces
alongside the Rio Grande at Interstate 10 and will serve the communities of north and central Mesilla
Valley. Phase 1 construction for this plant will provide a total treatment capacity of 20 mgd with the
capability for later expansion to 26 mgd and finally to 34 mgd capacity. Phase 1 will include the
construction of all transmission pipelines required for water delivery to Las Cruces and to the smaller
communities of north and central Mesilla Valley. This will make the Phase 1 20 mgd treatment plant
capacity available to service all areas of growth in the Las Cruces Area.
Raw water will be diverted to the Las Cruces Area Water Treatment Plant directly from a new diversion
on the Rio Grande and through a short 48-inch pipeline to the treatment plant. The plant will employ the
treatment process described above for the Hatch Area Water Treatment Plant.
Phase 1 distribution facilities include:
• 0.9 mile 48-inch transmission line to Las Cruces
• 15.4 mile north transmission line beginning at Las Cruces as a 24-inch line and reducing to a 14-
inch line at Dona Ana that extends to Radium Springs
• 1.6 mile 18-inch lateral transmission line to Dona Ana
• 11.7 mile 14-inch south transmission line extending from Las Cruces to Mesquite
• 2.6 mile 12-inch lateral transmission line to San Miguel
For Phase 1, a 20 mgd treated water pump station will be located at the Las Cruces Area Water
Treatment Plant site to pressurize the transmission lines. Later phases will expand the pumping plant as
additional pumping capacity becomes needed. Ultimate pumping capacity is expected to be 34 mgd.
Anthony Area Water Treatment Plant
The Anthony Area (South Planning Area) Water Treatment Plant, located in southern Mesilla Valley
near the community of Chamberino, will have a Phase 1 treatment capacity of 4.0 mgd with capability
for later expansion to 8.0 mgd and ultimately to 16 mgd. In Phase 1, the Anthony Area Water Treatment
Plant will provide treated water to the community of Anthony. Later expansions will extend treated
water service to the communities of Chaparral, Berino, La Mesa, Vado, and Chamberino.
A diversion facility at the Rio Grande will divert raw water will to the Anthony Area Water Treatment
Plant. The treatment plant will employ the treatment process described above for the Hatch Area Water
4
Treatment Plant. Following treatment, a Phase 1 pumping plant located at the treatment plant will pump
treated water to use through a transmission pipeline system. The system will begin as a 30-inch
diameter pipeline, reduce to a 24-inch pipeline, and further reduce to an 18-inch pipeline which will
extend to Anthony.
Factors that Impact the Construction Schedule
The New Mexico entities improvements component of the overall El Paso-Las Cruces Regional
Sustainable Water Project includes the three treatment plant and distribution systems described above.
These facilities have a total capital cost of approximately $75 million and a construction time line of
about 7 years. For such a large project, there are many factors that can have an impact on the
construction schedule. Such factors as the time length of the project, the desired completion dates for
each of the water treatment plants and service pipelines, required permits and contracts, construction
bonding requirements, and the desire to have local business participate in the project construction all
effect the schedule.
The ideal construction scenario is to complete the water treatment plants at the same time that the
distribution pipelines are completed. Concurrent construction will allow the entire system to begin
operation sooner. This will help prevent wasting of financial capital and construction warranty periods
for system components that might otherwise sit idle waiting for other system components to be
constructed. Also, flushing and cleaning of the system will be more efficient since the entire system can
be flushed and cleaned once rather than having to clean each component separately and then having to
do it again for disinfection once the system is completed.
Design/Construction Packages
The New Mexico entities water treatment and distribution systems improvements involve many different
communities scattered for many miles along the Rio Grande. Different funding mechanisms and
numerous approvals and permits will be required from many different city, state, and federal agencies.
Separate design and construction packages for each of the three planning area water treatment and
distribution systems are therefore prudent.
Management of the design, land acquisition, permitting, and construction can be accomplished either
under an umbrella program management approach or under a separate project approach. The program
management approach would involve a lead agency, such as the county, that would hire a program
management consultant to coordinate all activities required to construct all three systems. The separate
project approach would either require each set of communities in each planning area to obtain funding,
obtain permits, and oversee design and construction of their system separately; or the county could act
as the lead agency for performing these functions.
5
Due to the fragmented nature of the planning area systems and the communities served, the program
management approach is probably not warranted for New Mexico entities improvements. The better
approach appears to be for separate project management for each of the three planning area systems with
the county acting as the lead agency to be the prime mover for coordination between the communities
and keeping each planning area project on-track. This latter approach was assumed for the estimates
presented herein.
Design activities for each of the planning areas are quite similar. Each involves the design of a
diversion structure on the Rio Grande, the design of a membrane water treatment plant with identical
processes, and the design of pump stations and transmission lines. Each project should thus be divided
into separate design packages for the diversion structures, the treatment plants and pump stations, and
the transmission pipelines. The greatest efficiency in design and shared maintenance may result if
similar the designs are developed for the diversions and treatment plants.
For each distribution system, transmission pipeline design packages may be awarded for each Phase 1
system as a whole or may be divided into separate design packages for each major pipeline segment.
The latter would better achieve the goal of providing maximum opportunity for local design and
construction firms and has therefore been assumed for the estimates presented herein. Table 1 describes
the design and construction packages.
Construction Workforce Estimates, Duration Estimates, and Overall Project
Schedule
Construction workforce estimates were determined based on the level of effort required to perform a
specific activity. Workforce estimates for distribution facilities were prepared by Parsons Engineering
Science in consultation with Burns Construction Company who has constructed numerous pipelines in
the Las Cruces area and Greg Fischer of Ames Construction who has constructed numerous pipelines in
Utah. Since there are no local New Mexico contractors familiar with water treatment plant construction,
Parsons compared its experience on other projects with the information developed for El Paso Upper
Valley Water Treatment Plant. Construction activities for the diversion facilities, treatment plants,
pumping stations, and distribution pipelines can proceed independently and concurrently. Minor
coordination activities are necessary between the components of each system to ensure matching of
locations, lines, and grades.
The major activities of the project design and construction schedule are shown on Table 2. Project
construction manpower requirements on a monthly basis were prepared overlaying the estimate of
individual construction project workforce requirements on the overall construction project schedule.
Table 2 is a summary of construction manpower requirements by month for the entire period that
construction is expected to occur.

Environmental Surface Exposure
During construction, work will be performed within permanent easements and sites and also in
temporary construction easements obtained specifically for construction of the improvements. A
summary of soil disturbance areas for New Mexico’s portion of the El Paso - Las Cruces Regional
Sustainable Water Project is listed in Table 3.

Fuel Depots
Construction vehicle and equipment fueling requirements are based on the size of construction site
available, location and proximity of construction activity to existing fuel sources and type of equipment
required to perform the actual construction work. Options identified are:
• On-Site Storage. – For construction activities on a fixed site where there is 24-hour security and
a need for vast quantities of fuel, fuel may be stored on site.
9
• Existing Facilities – For mobile construction equipment where fuel is required on an irregular
basis, such as other than daily or several times a day, it may be cost effective to purchase fuel at
existing sites. In the particular case of gasoline powered equipment this is the preferred method
of fuel storage since non-construction vehicles also use the same fueling facilities.
• Jobber Service – Where equipment is relatively immobile, but requires fuel on a regular and
generally daily basis, it is common to enlist the services of an independent fuel service to provide
on-site fueling of equipment.
• Combination – Many combinations of fuel service are available and applicable for some
construction activities. For example, pipeline construction is a construction activity where
gasoline driven machinery is often driven to the closest existing facilities on an as-needed basis
while excavation and backfill equipment may be serviced by the general contractor’s service
vehicles, using above ground fuel storage erected on the specific project.
Table 4 summarizes the location and type of fuel depots anticipated for each construction project.

Groundwater and NPDES Permitting
Permits are required for three main activities during the construction process for the New Mexico
entities improvements. A significant portion of construction activities involves groundwater dewater
activities in the Rio Grande Valley. Phase 1 pipeline construction involves flushing and testing of
nearly 14 miles of water transmission lines. In most cases, if construction related water is discharged
into an arroyo or can reach waters or the United States when discharged, a permit is required.
Dewatering Activities
Excavation in the flood plain region of the Rio Grande Valley area will require dewatering. A discharge
permit must be obtained from the State of New Mexico before beginning any dewatering operations.
The permit will require the permittee to estimate the concentrations Total Petroleum Hydrocarbons
(TPH), Total Dissolved Solids (TDS), Total Suspended Solids (TSS), pH, and sulfate in the dewatering
discharge. If any of these constituents are determined to exceed the allowable levels, the permit request
may be denied. If the permit is denied, another method for disposal of the water would be required, such
as treating the water prior to disposal, or the method of construction would have to be modified to
eliminate the undesirable discharge constituents.
Discharge to canals or agricultural drains will require approval of Elephant Butte Irrigation District
(EBID). Discharge to storm sewers will require approval of the municipality or entity responsible for
the storm sewer. In any case, discharge reaching the river will require a State of New Mexico National
Pollution Discharge Elimination System (NPDES) permit.
Use of Chlorinated Water or Discharge to Arroyos or Waters of the United States
Where possible, water used for testing should be reused to minimize the amount of water wasted.
Discharge of chlorinated water from flushing operations and disinfection into storm or sanitary sewers
will require approval of the municipality or entity responsible for the facility. Discharge onto the
ground will require State of New Mexico Environment Department approval. Discharge into an arroyo,
the Rio Grande, or other waters of the United States will require a state NPDES permit. Dechlorination
treatment will be required for discharges to the natural environment.
Storm Water Discharges from Construction Activities
An NPDES permit will be required for any construction activity disturbing at least 5 acres, or
construction activity disturbing less than 5 acres which is part of a larger common plan of development.
All three of the planning area water treatment and distribution systems will fall within these criteria.
Therefore, NPDES permits for the construction of each of these systems will be required. Table 5
summarizes potential permit requirements for the New Mexico entities improvements.

Staging Areas
Staging areas, for use by the contractor and the New Mexico entities representatives vary in accordance
with site specific work activities. Staging area requirements for major construction components such as
water treatment plant, diversion, and pipeline construction were evaluated. Staging areas for the major
work activities for each treatment and transmission system for New Mexico’s portion of the El Paso –
Las Cruces Regional Sustainable Water Project are described below:
• Project Management – Project management will be conducted either from existing municipal
entity offices or at on-site trailers at the staging area sites for the construction.
• Treatment Plants/Pump Stations – The treatment plant/pump station sites should be of
sufficient size to provide equipment and supplies storage for not only the contractor, but also for
owner representative construction offices as well.
12
• Diversion Structures – A staging area of approximately 1-acre will be required at or near the
Rio Grande diversion structure for the contractor’s construction trailer and for storage of
construction materials.
• Pipeline Distribution Systems – Transmission line construction activities should be contained
within the anticipated construction easements. Pipe will be transported to the general project
vicinity by truck and laid (strung) along the transmission line alignment in front of the
installation crew on an as-needed basis. Equipment such as backhoes, front-end loaders, and
compactors will be staged along the pipeline route. An additional one-half acre of land
somewhere along the pipeline route will be required for the contractor’s trailer and
miscellaneous equipment and materials storage.

Construction Details for Identified
Improvements for El Paso Water Utilities
General Description of the System
EPWU’s identified needs include processing of 80 mgd of water from the Upper Valley Water
Treatment Plant (UVWTP). Raw water will be conveyed from Mesilla Dam to the UVWTP by one of
two methods. The first method utilizes the New Mexico-Texas Aqueduct to transfer water between the
two sites. This method’s recommended option involves pumping water from immediately downstream
of the Mesilla Dam into the Westside Regulating Reservoir for presedimentation and storage purposes.
A gravity system comprising some 22.4 miles of 72-inch diameter pipe would convey water from the
Westside Regulating Reservoir to the UVWTP. The second method of transport involves transporting
raw water down the Rio Grande River to the UVWTP site, where a diversion structure either across or
along the side of the Rio Grande River at the UVWTP site would be constructed to capture the water for
treatment at the site.
Once the raw water has been conveyed to the UVWTP, water would be pumped under either scenario
into an on-site settling basin. Water will then be treated to Safe Drinking Water Act (SDWA) standards
using either conventional or membrane treatment technology, disinfected, and then placed into on-site
finished water storage, to await distribution as required in EPWU’s distribution system or into the ASR
System as contemplated by the project.
Initially, 20 mgd will be pumped from the UVWTP into northwest El Paso to the Canutillo production
transmission system, through a 60-inch transmission line. The remainder, 60 mgd, will be supplied via
the El Paso Aqueduct System, from the UVWTP, over the Anthony Gap and into northeast El Paso. All
water delivered to northeast El Paso through the El Paso Aqueduct System will be used first to meet area
demands, in lieu of pumping from existing wells in the Hueco Bolson. During early years of operation,
20 mgd of the 60 mgd may be used to meet the northeast area demands. Water in excess of that required
to meet demands will be diverted to one or more of the five selected ASR service areas for recharge
through the network of ASR wells. In later years, less water will be available for injection as more
water is used to meet the northeast area’s demands.
As EPWU’s northwest side system demands increase, it is expected that up to 40 mgd of the total 80
mgd UVWTP capacity will be utilized in northwest El Paso, with the remaining 40 mgd being
transferred to northeast El Paso.
Factors that Impact the Construction Schedule
EPWU’s Alternative improvements component of the overall El Paso – Las Cruces Regional
Sustainable Water Project includes the New Mexico - Texas Aqueduct, Upper Valley Water Treatment
Plant, El Paso Aqueduct, and the Northeast El Paso Aquifer Storage and Recovery System. The cost of
these project improvements is estimated to be in the range of $246,000,000 to $316,000,000. The
targeted completion date for the entire project is the spring of 2005, prior to the summer peak system
demand. Many elements impact the construction schedule. The sheer size of the project, overall desired
15
completion date, similar work effort requirements, construction bonding requirements (EPWU currently
requires a minimum bonding capacity for any of its construction contracts of $15,000,000), and desire
that local business be afforded an opportunity to participate in its construction are all factors that impact
the construction schedule. The construction of several improvement components cannot be completed
until other improvement component construction has been completed and placed on line, such as water
for flushing and testing the El Paso Aqueduct must be supplied from the UVWTP through the El Paso
Aqueduct stations and reservoirs. It is also not prudent to have equipment in place and not in service
through its warranty period, capital investments not used for years, or facilities such as wells disinfected
at the construction completion phase and then idle for years, requiring disinfection before being placed
in service.
Design/Construction Packages
The project, providing a sustainable water supply to El Paso and its neighbors in New Mexico, is a very
large and complex project. The project comprises construction activities over a substantial physical
territory. It will require coordination of the significant simultaneous design and construction activities
of numerous engineering and construction firms, and will also require approvals and permitting from
numerous local, state, and federal agencies. To keep the projects focused, coordinated, and moving and
to act as a clearinghouse for the various activities, a program manager concept is proposed. The job of
the program manager, along with his assistant program managers, will be to first insure the work effort
progresses in accordance with the interests of EPWU and insure the activities are coordinated.
The overall project can be easily divided into the four major topics listed above – namely, the New
Mexico – Texas Aqueduct, Upper Valley Water Treatment Plant, El Paso Aqueduct, and Northeast
Aquifer Storage and Recovery System. Table 6 describes the design and construction packages. Each
major improvement component is described below.
New Mexico – Texas Aqueduct
EPWU’s portion of the recommended New Mexico – Texas Aqueduct alternative, Option D, comprises
constructing some 22.4 miles of 72-inch diameter pipe between the Mesilla Dam and UVWTP site. This
design and construction effort, which will cost nearly $50,000,000, is considered to be one design phase
and under only one construction contract for several important reasons. It is one contiguous project that
must deal with similar permitting and right of way issues with the same authorities throughout its entire
length, requires similar equipment to install identical material, and there is sufficient time available for
the design and construction activities.

Upper Valley Water Treatment Plant
The UVWTP project consists of design and construction phase activities of sophisticated equipment and
supporting infrastructure for a water treatment plant within one specific designated site. The cost of the
UVWTP, which is estimated to cost from $103,510,000 to $121,260,000 to design and construct,
includes approximately $2,500,000 estimated for the Open Intake River Diversion Structure located
adjacent to the UVWTP site and required in the event the New Mexico – Texas Aqueduct is not
constructed. This essentially independent or stand alone design and construction effort is considered to
be one design phase and construction phase. Both the design and construction phase require intricate
coordination of numerous disciplines for the design phase as well as the work trades during the
construction phase to successfully build this complex water treatment plant and its auxiliary systems.
El Paso Aqueduct
The El Paso Aqueduct project comprises a series of booster stations and reservoirs, along with 9.5 miles
of 60-inch diameter, 9.4 miles of 42-inch diameter, and 8.9 miles of 48-inch diameter transmission line
to convey water from the UVWTP site to the Anthony Gap Summit and then into EPWU’s northeast
water distribution system. It also includes 4.24 miles of 60-inch diameter transmission line between the
UVWTP site and the existing Canutillo production transmission system.
As with the New Mexico – Texas Aqueduct the El Paso Aqueduct comprises similar design and
construction activities, along with similar permitting and approval processes. Therefore, it is reasonable
to break the project into no more than two design contracts—one from UVWTP to the Anthony Gap
Summit and one from the Anthony Gap Summit into northeast El Paso. However, the fact that the
aqueduct traverses numerous sites between UVWTP and northeast El Paso, coupled with the fact that
the estimated construction cost just for the transmission lines is approximately $47,000,000 and coupled
with the desire by EPWU to give local contractors the opportunity to bid on specific construction
packages, numerous construction packages for the El Paso Aqueduct transmission lines are
recommended.
Similar logic was used in evaluating the booster stations and reservoirs. Booster stations will be nearly
mirror images of each other for design simplicity and ease of maintenance, being modified only as
required to comply with the minor hydraulic changes from one station to another. For this reason, it is
suggested that the booster station component be based on one design and one construction phase
contract. Similar logic dictates the reservoir design be performed by one firm. However, the nearly
$10,000,000 estimated construction cost combined with the desire to give local contractors the
opportunity to bid on specific construction packages results in two construction packages being
recommended. The first construction package is for the booster stations and the second is for the
reservoirs.
18
Aquifer Storage and Recovery
The Northeast El Paso Aquifer Storage and Recovery System (ASR) comprises drilling and equipping
71 injection/recovery wells, and constructing well collector line systems to convey either water through
the El Paso Aqueduct into the wells, in injection mode, or from the well site into distribution system
treatment and storage reservoirs in recovery mode.
The well drilling phase of the contract will involve drilling through a media, which cannot be examined
or described exactly. Estimates of the formation underlying each well site will be prepared prior to
drilling so the contractor is aware of the approximate work effort required to drill the well. As work
proceeds at each site, the drilling will be modified as required to construct the most efficient well. Once
the well has been drilled and test pumped its specific production and water drawn down characteristics
can be described. Knowledge learned from the well drilling construction phase is essential in describing
the permanent pumping equipment that will be then constructed at each site. Based on the time
available for drilling and equipping 71 ASR wells, it is assumed that the well drilling will precede the
well equipment by several months.
Since coordination and sharing of site specific data obtained during the is critical for the equipping
phase of the project well drilling and well equipment design activities are envisioned as a single activity.
And, since the critical data will be shared within the design phase and since well drilling and different
construction firms often perform well equipment activities, well drilling and well equipment
construction activities are separate construction packages.
Well collection system design and construction are single-phase activities and will be one construction
package.
Construction Workforce Estimates, Duration Estimates, and Overall Project
Schedule
Construction workforce estimates were determined based on level of effort required to perform a
specific intended activity. These workforce estimates were prepared by Boyle Engineering Corporation
in conjunction the expertise of a Vice President of Bradbury Stamm Construction, Inc., an Engineering
News-Record top 400 (224 in 1997) contractor. Bradbury Stamm Construction, Inc., is a well-respected
construction firm in the region that is familiar with the terrain, work force, and general construction
climate in and near El Paso. Level of effort included skill level and construction supervision by the
contractor of their workforce. Pipeline construction, for example, was divided into three categories of
workforce effort—installation of 12-inch diameter through 20-inch diameter pipe, 24-inch diameter
through 42-inch diameter pipe, and 48-inch diameter and up pipe, based on the different levels of effort
required to trench, place spoil, install, and finally backfill and compact the trench. Office support was
estimated for each workforce category.
19
Coincident with workforce estimates, duration estimates were created for both the design phase services
identified in Table 1 and for each individual construction package. Dependencies between construction
packages were also evaluated. Specific issues concerning construction packages are provided below:
• New Mexico – Texas Aqueduct – Design and construction activities are primarily independent
of all other design/construction activities. Minor coordination activities will be required between
it and the UVWTP design effort.
• UVWTP – The treatment plant design and construction activities are primarily independent of
other design/construction activities. Minor coordination activities will be required between it
and the New Mexico – Texas Aqueduct and the El Paso Aqueduct.
• El Paso Aqueduct – Design phases of the El Paso Aqueduct components, which include pipe
line design, reservoir design, and pump station design, will require minor coordination
requirements between those components. Construction activities are dependent not only on
individual component construction activities, but are also dependent on the UVWTP construction
completion. Two specific issues must be considered. The first is that water in sufficient
quantities will not be available for flushing/disinfecting/testing the transmission lines until the
plant is on line. It will take over 7.0 million gallons just to fill the transmission line between the
UVWTP and the El Paso Aqueduct Anthony Gap Summit Reservoir. The second issue is that
the facilities cannot be used until the UVWTP is complete since the plant is the source of water
for Northeast El Paso. The capital cost should not be incurred until the facilities are capable of
being used. The normal warranty period for equipment is one year, which should commence
only when the facilities are on line, rather than commence when the equipment cannot be used.
• ASR Well Drilling and Equipment – The design activities for well drilling and equipment are
very dependent, as described earlier in this Technical Memorandum. Since one firm performs
design services, and in doing so the data obtained during the construction phase is transmitted to
the equipment design phase, the construction activities will be performed under two separate
construction contracts. As with other construction components, particularly with substantial
equipment, this entire activity is scheduled to begin as late as possible so the well sites are
complete just after the UVWTP construction is complete.
• ASR Collector Line – The ASR well collector line system design and construction is relatively
independent of other activities except that the well sites must be selected and there is no need to
complete construction until the wells have been equipped and the UVWTP is in operation.
The major activity components of the project design and construction schedule are shown on Plate 1. A
detailed schedule showing breakdown of both the design and construction of all El Paso improvement
components is included as an insert to this report in Appendix A.

Project construction manpower requirements on a monthly basis were prepared by overlaying the
estimate of individual construction project workforce requirements on the overall construction project
schedule. Table 7 is a summary of construction manpower requirements by month for the entire period
that construction is expected to occur.
Environmental Surface Exposure
During construction, work will be performed within permanent easements and sites and also in
temporary construction easements obtained specifically for this project. Construction activities, which
involve soil disturbance, were identified for specific project components in several technical
memorandums. These include land requirements for both the regulating reservoir and pipe line
construction described in the Study of Conveyance Facilities for Year-Round Delivery of Surface Water
to Water Treatment Plants (New Mexico – Texas Aqueduct), Draft, July 1999, water treatment plant
land requirements described in the El Paso Upper Valley Water Treatment Plant Conceptual Site
Layout, June 1999, facility sites and pipe line proposed easements (temporary and permanent) in the El
Paso Aqueduct Conceptual Design, Draft Final Report, June 18, 1999, and facility sites as contained in
Concept Design of ASR Wellfield and Collection Facilities, Final Report, July 1999. A summary of soil
disturbance areas for El Paso’s portion of the El Paso – Las Cruces Regional Sustainable Water Project
is listed in Table 8.
Fuel Depots
Construction vehicle and equipment fueling requirements are based on the size of construction project,
size of construction site available, location and proximity of construction activity to existing fuel sources
and type of equipment required to perform the actual construction work. As with the construction
workforce estimates and project duration estimates, the experience of a Vice President of Bradbury
Stamm Construction, Inc., was utilized to evaluate fuel depot requirements. Numerous options were
identified, based on the specific supply requirements, for example diesel fuel versus gasoline, quantities
of supplies needed, availability of 24-hour site security, and proximity to existing independent suppliers.
The options identified are described below. Table 9 summarizes the location and type of fuel depots
anticipated for each construction project.
• On-site fuel storage – On sites where there is 24-hour security and a need for vast quantities of
fuel, fuel may be stored on site.
• Existing Facilities – Construction activities in which fuel is required on an irregular basis, such
as other than daily or several times a day, and that the equipment is mobile it may be cost
effective to purchase fuel at existing sites. In the particular case of gasoline powered equipment

this is the preferred method of fuel storage, since non-construction vehicles also use the same
fuel.
• Jobber Service – In cases in which equipment is relatively immobile, but requires fuel on a
regular, generally daily basis, it is common to enlist the services of an independent fuel service to
provide on-site fueling of equipment.
• Combination – Many combinations of fuel service are available and applicable for certain
construction activities. Pipe line construction, for example, is a construction activity in which
gasoline driven machinery is often driven to the closest existing facilities on an as needed basis
while the excavation and backfill equipment would be serviced by the general contractor’s
service vehicles, using above ground fuel storage erected for the specific project.
25
Groundwater and NPDES Permitting
Permits are required for three main activities during the construction process for the El Paso
construction projects. A significant portion of construction activities involves groundwater dewatering
activities in the Rio Grande Valley and well development activities for the 71 ASR wells in Northeast El
Paso. Pipeline construction involves flushing and testing of nearly 83 miles of water transmission and
well collector lines. In most cases if construction related water is discharged into an arroyo or can reach
waters of the United States when discharged, a permit is required.
Dewatering Activities
Excavation in the flood plain region of the Rio Grande Valley area will require dewatering. According
to Terry McMillan, Texas Natural Resource Conservation Commission (TNRCC) Division Manager,
Region 6, Water and Wastewater Section, a discharge permit must be obtained before beginning any
dewatering operations. The permit will require the permittee to estimate the concentrations of Total
Petroleum Hydrocarbons (TPH), Total Dissolved Solids (TDS), Total Suspended Solids (TSS), pH, and
sulfate in the dewatering discharge. If any of the above constituents are determined to exceed the
allowable levels, the permit request may be denied. If the permit is denied, another method for disposal
of the water would be required, such as treating the water prior to disposal, or the method of
construction would have to be modified to eliminate the undesirable discharge constituents.
EPWU has an existing agreement with El Paso County Water Improvement District No. 1 (EPCWID
#1), dated April 11, 1997, for dewatering fees. EPCWID #1 will perform the monitoring of the
dewatering discharge. Based on communication with Ed Fifer, General Manager of EPCWID #1, TDS
will be the only constituent monitored during the construction. If the TDS concentration exceeds 1,000
ppm, EPCWID #1 will fine the contractor $0.05 per acre-foot discharged. EPCWID #1 discourages
discharges to the river, canals, or irrigation ditches. They prefer approving discharges to the agricultural
drains because that water is usually of lower quality when it comes off the irrigated fields. At this time,
EPCWID #1 is unaware of any water quality issues or discharge limits that would severely impact the
dewatering operations.
Use of Chlorinated Water or Discharge to Arroyos or Waters of the United States
Where possible, water used for testing should be reused to minimize the amount of water wasted.
Discharge of chlorinated water from flushing operations and disinfection will have to be coordinated
with the City of El Paso, if the water is discharged into its drainage and/or wastewater facilities, or with
TNRCC or New Mexico Environment Department if the water is discharged onto the ground. Discharge
into an arroyo or waters of the United States may require a National Pollution Discharge Elimination
System (NPDES) permit issued by the TNRCC/EPA for construction in Texas or by the Environment
Protection Agency (EPA) for construction in New Mexico.

Storm Water Discharges from Construction Activities in Region 6
A National Pollution Discharge Elimination System (NPDES) permit will be required for any
construction activity disturbing at least 5 acres, or construction activity disturbing less than 5 acres
which is part of a larger common plan of development. At least one storm water pollution prevention
plan (SWPPP) must be developed for each construction project.
Table 10 summarizes potential permit requirements for EPWU’s Construction Projects under the
El Paso – Las Cruces Regional Sustainable Water Project.
Staging Areas
Staging areas, for use by the contractor and also for use by El Paso Water Utilities and their
representatives, vary in accordance with site specific work activities. Staging area requirements for
major construction components including water treatment plant construction, well drilling and
equipment, pipeline construction and booster station construction were discussed with the Vice
President of Bradbury Stamm Construction, Inc., at the same time other phases of construction were
discussed. The reservoir construction phase activities represent a significant but separate work effort
than the aforementioned construction activities. To determine how construction for five steel on-grade
reservoirs could be accomplished under two construction contracts, PDM Water, a Division of Pitt-Des
Moines, Inc. was contacted to solicit their input concerning industry standards for this type reservoir
construction. Pitt-Des Moines, Inc., is also a member of the Engineering News-Record top 400 (93 in
1997) contractors and ranked number 5 in water supply.
The major work activities with resulting staging areas for each construction project of El Paso’s portion
of the El Paso – Las Cruces Regional Sustainable Water Project are described below:
• Program Management Activities – A multitude of concurrent construction activities will occur
over a very large area. To effectively assure construction activities are coordinated and that
problems can be addressed in a timely manner it is envisioned that Program Management trailers
will be located at two locations. One will be located on the UVWTP site, while the second
should be located at some location on the eastside of El Paso in conjunction with the construction
activities in northeast of El Paso.
• Upper Valley Water Treatment Plant – The overall site contains 233 acres. It is anticipated
that the site will be sufficient to provide equipment and supplies storage for not only the
contractor but also EPWU and their construction and program management representatives.
• Transmission Line Construction Activities - Transmission line construction activities are
expected to be contained within the anticipated construction zones areas identified earlier in this
Technical Memorandum for each project. Pipe will be transported to the general project vicinity

by truck and laid (strung) along the transmission line alignment in front of the installation crew
on an as-needed basis. Equipment such as backhoes, front-end-loaders, and compactors will be
staged along the pipeline route.
• Pump Station Construction – It is anticipated that the pump station sites will be sufficient in
size to allow storage of equipment and supplies on site. Also, EPWU and their representatives’
construction facilities will be located on each designated booster station site.
• Well Drilling and Equipment – An area comprising 1-½ acres has been set aside during the drilling
phase to accommodate the extensive equipment and drilling pits required for that construction phase
period. Well drilling activities, which include drilling equipment, fluid-recirculating pits, casing and
gravel supplies will be contained on site. Well holding pits will not be constructed until the well
casing has been set. Equipment construction activities, which include a large rig required for setting
the pump assembly and column piping, will also be contained on-site. Any construction facilities
required by EPWU or their representatives will also be contained on site. Once construction
activities have been completed, 1 acre has been set aside for each permanent well site.
• Reservoir Construction – All materials and equipment for field erection can be contained on-site.
Also, reservoir foundation work will all be contained on-site. Because of the magnitude of the two
reservoir projects reservoir steel preparation, which includes cutting and forming the steel shell and
shop priming the shells prior to erection activities will be performed at the contractor’s fabrication
plant. The fabrication site will depend on the contractor selected, but in any case the fabrication site
will not be located in the vicinity of the El Paso – Las Cruces Regional Sustainable Water Project.
Once the steel has been fabricated and shop primed, it will be transported by truck to its erection site.
This form of transportation will require loading the supplies once at the fabrication site and
unloading it once only at the erection site. If the steel were transported by rail, which is an viable
alternative in El Paso, at least one more unloading and reloading activity would be required at the
railhead. Any construction facilities required by EPWU or their representatives will be contained on
site at each individual reservoir site.
