Section A-1 – Design Requirements Overview
The following are the design requirements for the project. Further reference information can be found
in the Preliminary Design Report (PDR) attached as Appendix 2 of Volume III-B.
1.1 Well Field
Three groundwater wells will be included in the NTWFP (Well Nos. 9, 10, and 11). The design of the
wells and construction details are discussed in the following sections. The design flow from the well
field is 9,000 gpm, or 14,510 af/yr.
1.1.1 Well No. 9
Geoscience Support Services, Inc. (Geoscience) designed and observed the construction. Well
construction details are summarized in a report entitled Results of Drilling, Construction, Development
and Testing by Geoscience, May 2009 (Appendix 2). This well has the following characteristics:
Specific capacity = 39 gpm/foot.
Sustainable well yield = 3,000 gpm (4,840 af/yr).
18-inch-diameter casing.
Screen intervals: 190 to 310 feet, 330 to 470 feet, and 500 to 550 feet below ground surface (bgs).
Well depth = 594 feet bgs.
Discharge from Well No. 9 will be rerouted southerly on Yukon Avenue to the project site.
1.1.2 Well No. 10
The pilot hole for proposed Well No. 10 was drilled at the project site in June 2009 to determine water
quality parameters and develop the design for the well. Geoscience observed the construction of the pilot
hole and prepared a report recommending the well design (Appendix 2). As described in the PDR, the
well was drilled to a depth of 904 feet bgs and backfilled to a depth of 46 feet bgs. The conductor casing
was installed and grouted in place. See Drawing M-501 in Appendix A, Section A-2 of Volume III-A for
the well design diagram. The well will be completed as part of this project at this location. The required
well yield is 3,000 gpm.
1.1.3 Well No. 11
Well No. 11 is proposed to be constructed just west of Yukon Avenue, north of the I-405 Freeway within
the old Yukon Avenue right-of-way dedicated to the City, and is expected to be similar to existing Well
No. 9. The required well yield is 3,000 gpm.
Discharge from Well No. 11 will join the pipeline from Well No. 9 and proceed to the plant site.
1.1.4 Well Construction Requirements
All work is to be in accordance with the City of Torrance, California Department of Water Resources and
California Division of Drinking Water (DDW) standards. Prepare source water assessments for each new

Design-Build of North Torrance Wellfield Project Volume III – Contract Appendices
8 May 2017
Floors shall be constructed of reinforced concrete, 6-inch minimum thickness, with a light broom finish to
provide a slip-resistant surface. Floors shall be sloped a minimum of 1 percent to floor drains. Floor slab
of new buildings shall have a moisture barrier and be treated with a chemical hardener.
1.2 Reservoir
A reservoir is to be provided as a forebay for the BPS and for emergency storage.
1.2.1 Capacity
The reservoir capacity shall be 3.0 MG. The site will allow a tank with a maximum diameter of about 115
feet.
1.2.2 Configuration and Material
A single circular reservoir shall be provided with the following characteristics:
Provide 3 feet of freeboard below the reservoir roof.
For a prestressed concrete tank and 40-foot height, the side water depth would be 37 feet and
diameter 118 feet.
The bottom of the reservoir will be 20 feet below grade.
Design the reservoir per Section 64585, CCR Title 22, and AWWA D110, Type I standards and the
following criteria:
Current site-specific seismic data will be used for the design.
The minimum floor thickness will be 6.5 inches for durability and reinforcement clearances per
ACI 350, Code Requirements for Environmental Engineering Concrete Structures.
The roof will be a geodesic aluminum dome design.
Roof access hatch and vents will be provided.
The reservoir will be fitted with interior washdown connections and lighting at the roof entrance.
The reservoir layout will include inlet, outlet, overflow, and drain piping.
Provide stairway access to the top of the reservoir. Bottom is to be secured to prevent unauthorized
access. Stairway shall be free-standing, with stability connections to the reservoir only at the
landings.
1.3 Booster Pump Station (BPS)
The BPS is to discharge treated water to the City’s distribution system.
1.3.1 Capacity
The station capacity is to be equal to the total project design inflow capacity of 9,000 gpm. Because the
well flow will be variable, due to fluctuating groundwater conditions and water system gradient, and
operational flexibility is required, two pumps will be provided with a variable frequency drive (VFD) to
provide a means of matching total inflow.
Select vertical turbine booster pumps as follows:
Design-Build of North Torrance Wellfield Project Volume III – Contract Appendices
9 May 2017
Two pumps could run at full speed.
Pump design flow rate = 4,500 gpm.
Pump shall be capable of pumping from the reservoir with five feet of water depth to the first
piping connection in Yukon Avenue. At this point, the HGL will vary from 353 feet (minimum
day system demand) to 303 feet (peak hour system demand).
For pipeline friction, assume HW coefficient (C) of 120.
Consider valve and fitting head losses.
See Section 6.5 of the PDR for preferred manufacturers.
1.3.2 Layout
Three vertical turbine pumps are to be provided (two to run plus one standby), each with a capacity of
4,500 gpm; preliminary estimate of 291-ft head and 450 HP which needs to be analyzed and designed by
the Company. A representative pump selection may be a Peerless 18HXB three-stage pump operating at
1,760 revolutions per minute (rpm).
1.3.3 Discharge Pipeline
A 24-inch pipeline from the BPS will be connected to two points within the distribution system:
To the existing 12-inch line in Yukon Avenue, and,
Extend an 18-inch line southerly in Yukon to connect to a 12-inch line in 182nd
Street.
Appendix A, Section A-2 of Volume III-A includes Drawing C-104 for the yard piping plan, Drawing C-
10 for offsite piping in the utility easement and northerly along Yukon, and Drawing C-202 for offsite
piping crossing the I-405 Freeway.
1.3.4 Surge
1.4 Drain Lines
Several drain lines are required for disposal of project waste flows, as follows.
1.4.1 Reservoir Overflow and Drain
Under a worst-case scenario (failure of the wells to shut down on high reservoir level), the overflow line
must be designed to dispose of the full 9,000-gpm well inflow. This will require a 30/24-inch gravity
pipeline and connection to an existing manhole in Yukon Avenue north of 182nd
Street, which is
connected to a 9-foot by 10-foot reinforced concrete box (RCB) culvert in 182nd
Street. To maintain
gravity flow, the pipeline must cross the I-405 Freeway via a jacked steel casing westerly of and parallel
to Yukon Avenue. Discharge from two freeway drain lines will be diverted to this line. See Appendix A,
Section A-2 of Volume III-A Drawings C-107, C-201, C-202, and C-204 for the plan and Drawings C-
203 and C-204 for the profile. If constructed early, this line could be used for disposal of well
development water.
Design-Build of North Torrance Wellfield Project Volume III – Contract Appendices
10 May 2017
1.4.2 Drain to Sewer
The rest room, laboratory, and chemical room drains will require a connection to the sewer for disposal.
The point of connection will be an existing manhole in front of the school. This line is shown in Drawings
C-104 and C-107; the profile is in Drawing C-205 in Appendix A, Section A-2 of Volume III-A.
1.4.3 Well Flush Lines
Flush water from Well Nos. 10 and 11 will be routed to connections to the reservoir overflow drain line.
Flush water from Well No. 9 will be discharged at Well No. 11.
1.4.4 Blending
A blend line has been provided for future blending or treatment to meet TDS or other treatment
requirements. Future blending may be required should imported water meet TDS levels well below 500
ppm. A future RO treatment process will generate a waste concentrate flow which will be disposed of to
the existing 6” VCP sewer system. A holding tank could be required to regulate concentrate flow. The
blend line can also be used as a potable water line for the site. The blend line is currently stubbed out to
Yukon Avenue, but is not connected.
1.5 Utility and Access Road Easements
A 24-foot wide utility easement has been obtained (Appendix 8 of Volume III-B) from the TUSD. It
will carry the well water pipeline into the plant, water from the plant to the distribution system, the
sewer for the rest room, future blending, the reservoir overflow storm drain, electrical conduit, and
fiber-optic cable conduit, as shown in Drawings C-104 and C-107 of Appendix A, Section A-2 of
Volume III-A.
The utility easement is overlaid with a 15-foot wide access road easement. The access road has been
installed. A six-foot chain-link fence and automated access gates with car reader will be required
between the school playground and access road and school parking lot and access road.
1.6 School Parking Lot Improvements
To provide for large vehicle access to the project site, the existing school parking lot was modified, per
Drawing C-108 found in Appendix A, Section A-2 of Volume III-A. The access road driveway will be
re-striped across the AC playground area and new gates installed for school access to the playground
and access road. This is being coordinated with TUSD.
1.7 Water Treatment
The water treatment system shall be designed for a flow of 9,000 gpm and provide treatment for the
bacteriological and virus disinfection as required by DDW.
The water treatment requirements are to be based on water quality analysis from Well No. 9. The
general chemistry results are summarized in Table 3.1, which show that the water from Well No. 9
meets all maximum contaminant levels (MCLs) established by the DPH based upon the initial sampling.
The complete analysis is provided as Appendix A in the PDR.
Provisions in the design shall include for treatment for fluoridation, hydrogen sulfide, iron and
manganese, and total dissolved solids (TDS). Treatment systems for fluoridation and hydrogen sulfide
Design-Build of North Torrance Wellfield Project Volume III – Contract Appendices
11 May 2017
are included in this project. If treatment systems for iron and manganese are determined to be required
through water quality testing, they would be extra work. A discussion of these constituents and their
treatment methodology is provided in the sections below.
1.7.1 Disinfection
The City practices disinfection by chloramination to maintain compatibility with imported water
supplies (the Metropolitan Water District chloraminates water treated at its treatment plants).
It is intended to inject both chlorine and ammonia into the water upstream of the reservoir to form
chloramine prior to storage and minimize the time the water experiences a free chlorine residual. An
additional chlorine residual analyzer and hypochlorite metering pumps will monitor reservoir effluent
combined chlorine residual and add hypochlorite if necessary to maintain the desired concentration.
To maintain compatibility with imported water, the chloramine concentration should be maintained at
about 2.2 milligrams per liter (mg/L) as total chlorine. Because there is some chlorine demand in the
water (assumed to be about 1.3 mg/L), this will require addition of about 3.5 mg/L of chlorine and 0.6
mg/L ammonia. Actual chlorine dose to maintain 2.2 mg/L in the reservoir effluent will be determined
by bench testing and operating experience. Based upon these doses and assuming a maximum well field
production rate of 9,000 gpm, the disinfection system will need to be able to supply about 378 pounds
of chlorine and 64 pounds of ammonia per day. Chemical requirements are summarized in Table 3.2.
Chlorine will be added as sodium hypochlorite, which will be purchased as a nominal 12.5 percent
solution, containing about 1 pound of effective chlorine per gallon. It will be stored in a 5,000-gallon
fiberglass storage tank, which will provide about 14 days of storage plus working volume to allow
receipt of a full truckload of hypochlorite.
Ammonia will be purchased as aqueous ammonia at a nominal concentration of 19 percent, containing
about 1.54 pounds of ammonia per gallon. Ammonia will be stored in a 500-gallon steel tank, which
provides 14 days of storage plus working volume. This volume is less than a full tank load (6,000
gallons). Due to its volatility and pungent odor, ammonia storage systems require installation of a
scrubber on the tank vent to capture ammonia fumes. The scrubber will be a small tank, 18 inches in
diameter, and filled with water to absorb the ammonia fumes. The tank will occasionally be manually
drained and refilled with fresh water.

1.7.2 Fluoridation
The City of Torrance currently practices fluoridation to be consistent with MWD water.
As seen in Table 3.1, the well water contains about 0.3 mg/L of fluoride. The U.S. Department of
Health and Human Services has recently issued a statement advising that water systems target a fluoride
concentration of about 0.7 mg/L to minimize dental cavity formation and avoid dental fluorosis.
Therefore, the fluoride feed system should be capable of providing about 0.4 mg/L of fluoride, or about
42 pounds per day.
Fluoride will be purchased as hydrofluosilicic acid, with a nominal concentration of 24 percent,
containing about 2 pounds of fluoride per gallon. It will be stored in a 500-gallon high-density
polyethylene (HDPE) tank, providing 14 days’ storage plus working volume. As fluoride vapors are
very corrosive, the tank will need to be ventilated through the roof.
1.7.3 Hydrogen Sulfide
(H2S) is seen in a number of Torrance wells. Spray nozzles shall be designed at the top of the reservoir
similar to other Torrance locations, so that well water is discharged into the reservoir through these
nozzles.
To address the possibility that H2S released from the water might lead to odor complaints from
populations near the reservoir, means shall be provided to add a scrubber capable of removing H2S
from air vented from the reservoir, should it be needed. To provide for this future scrubber, the reservoir
roof shall be designed and provided with a 2-foot diameter flanged outlet, located opposite the vent. In
the future, a 2-foot diameter duct should be extended to a blower and scrubber located on the ground
adjacent to the reservoir. A 10-foot by 15-foot space shall be required for this blower and scrubber.
1.7.4 Corrosivity
The design shall include corrosion control analysis and facility design and installation to meet DDW
requirements and address requirements described in the Corrosion Control Study Report (see Appendix
3).
1.8 Additional Treatment Requirements
While existing water quality information does not indicate the need for treatment beyond disinfection,
the City’s other wells in the vicinity of Well No. 9 experience a number of water quality issues that
Design-Build of North Torrance Wellfield Project Volume III – Contract Appendices
13 May 2017
require treatment. It is likely that, as the NTWFP begins to produce significant quantities of water, these
water quality issues may begin to appear. It is prudent, therefore, to include design for additional
treatment should it be required.
1.8.1 Iron and Manganese
As seen in Table 3.1, iron and manganese are present at concentrations below their secondary MCLs.
The manganese concentration of 41 µg/L is close to the MCL of 50 µg/L, and it may therefore be
possible that some manganese may accumulate in distribution system piping over time. This could lead
to occasional instances of black water if these deposits were disturbed, as might happen during flushing
operations. It is important to note that the black water would not be hazardous to health but would be
very displeasing aesthetically.
Iron and manganese are present at similar concentrations in other City wells, where they are
successfully dealt with by addition of a phosphate sequestrant/corrosion inhibitor (Carus 8500). This
sequestrant prevents precipitation and settling of the manganese, thus preventing accumulation of
manganese sediment in the distribution system. If manganese concentration should exceed 50 µg/L,
additional treatment may be required. This treatment would most likely consist of oxidation using
potassium permanganate or ozone and filtration through manganese greensand or other media filtration.
The design for these future facilities shall be provided.
The Carus 8500 product is an aqueous solution of phosphates with specific gravity of 1.35 to 1.41. It is
typically fed into the well water at a dose of 5 mg/L, which requires about 47 gallons per day. It will be
stored in a 1,000-gallon HDPE tank, which provides 14 days of storage plus working volume.
1.8.2 TDS Reduction
At the present time, groundwater at the NTWFP meets water quality requirements, however, the
groundwater basin has been impacted by seawater intrusion that occurred in the past. Based on this
information, future installation of a reverse osmosis (RO) system shall be designed as a part of this
project. Drawing C-101 found in Appendix A, Section A-2 of Volume III-A presents a conceptual
layout of the RO system.

1.9 Electrical Service
The electrical service shall include a new electrical transformer. The utility requirements shall be per
Southern California Edison (SCE) standards. The SCE transformer for the plant facilities shall be located
in the northeast corner of the site. A separate transformer for Well No. 11 shall be located adjacent to the
well building.
Design-Build of North Torrance Wellfield Project Volume III – Contract Appendices
14 May 2017
As shown in Drawing C-101 found in Appendix A, Section A-2 of Volume III-A, there is space at the
plant site for storage of two portable generator units for Well Nos. 9 and 11.
1.9.1 Main Switchboard
The power to the station shall be 480/277 volts, 3 phase, 4 wire. The main switchboard shall consist of
an underground pull section and one section with both the utility meter and the main circuit breaker.
The main circuit breaker shall have ground fault protection. The main electrical service shall have the
capability of powering a lead pump, a lag pump, and the pump for Well No. 10. The third booster pump
does not need to be included in the electrical load calculations as it shall be strictly a standby pump. The
main switchboard shall also include an automatic transfer switch, two VFDs for the booster pumps, one
solid-state starter for a booster pump, and one solid-state starter for Well No. 10. The main control
panel (MCC) will also include a 120/208-volt step-down transformer and panelboard for lighting and
auxiliary loads and a circuit breaker for the electrical room air-conditioning unit. Refer to Drawing E-
601 found in Appendix A, Section A-2 of Volume III-A.
Well No. 11 will not be fed from the BPS main switchboard; this well will require its own service.
Refer to the single-line diagram in Drawing E-602 found in Appendix A, Section A-2 of Volume III-A.
The future RO treatment process will require significant electrical loads (as outlined in Section 3.4 of
the PDR), which will not be included at this time. There are no provisions in the main switchboard to
feed the future RO treatment facility.
1.9.2 Emergency Power
A standby engine/generator (E/G) shall be provided to allow continued operation during a power
outage. The following features (motor) will be supported simultaneously:
Well No. 10. Well No. 11 will require its own electrical service because of the distance from the
plant site transformer. To provide required flows during an emergency, it is assumed that both
Well Nos. 9 and 11 will operate with a portable generator. This project will provide the two
generators and pre-built metal buildings for storage at the Site.
BPS. Two pumps, operating simultaneously.
Chemical pumps.
Air conditioning.
Miscellaneous electrical load.
An E/G unit shall be provided. Per City criteria, the fuel tank will be sized for a 48-hour run time during
a power outage. The fuel tank will be double-walled with leak detection alarms. The leak detection
alarm will have local and remote annunciation. The remote annunciation will be via the site
programmable logic controller (PLC) to City of Torrance Public Works Central Control via the
supervisory control and data acquisition (SCADA) system.
An above-grade diesel fuel tank shall be provided, to be located just outside the E/G room.
Approximate volume will be 5,000 gallons.
1.9.3 Utility Building Interior Lighting
Interior lighting shall consist of surface-mounted fluorescent, 1-foot by 4-foot enclosed and gasketed
fixtures. Lighting fixtures and lamps shall be California Title 24 compliant. Lighting fixtures with
Design-Build of North Torrance Wellfield Project Volume III – Contract Appendices
15 May 2017
emergency battery packs will be used to provide egress lighting during the transition from normal
power to emergency generator power. Lights will have generator backup power.
1.9.4 Chemical Room Lighting
The chemical room lighting shall consist of surface-mounted fluorescent, 1-foot by 4-foot enclosed and
gasketed fixtures and will be corrosion resistant. Lighting fixtures with emergency battery packs will be
used to provide egress lighting during the transition from normal power to emergency generator power.
Lights will have generator backup power.
1.9.5 Site Exterior (Security) Lighting
Exterior site lighting (security lighting) shall consist of metal halide wall packs mounted on the exterior
walls and metal halide fixtures mounted on 20-foot-high lighting poles. The exterior lighting will be
controlled via photocell controls to turn on at dusk and turn off at dawn. The site lighting levels shall be
kept within the property and shall not spill to the neighboring properties nor interfere with freeway
drivers.
The Caltrans right-of-way between the Caltrans block wall and the NTWFP Site block wall is a security
concern. Caltrans has requested this area be secured with chain-link gates and security cameras and
lights.
1.10 Security
1.10.1 Utility Building Intrusion Alarm
The building intrusion alarm shall consist of motion sensors located in the building interior. The motion
sensors will be deactivated when the vehicle electrical gate is opened via the proximity cards. Proximity
cards shall match the existing City’s cards. The system is monitored by a 3rd
-party firm via POTS phone
lines. The intrusion system shall be as follows:
Bosch 7412-GV4 control unit
Bosch D1255 keypad
Exterior Door Contacts GE 1076D concealed GE 2507 Surface mounted DPDT
Interior Protection will be detailed as the building design becomes finalized.
1.10.2 Security Closed Circuit Television (CCTV)
Cameras shall be used to monitor the perimeter and the interior of the NTWFP Site. The cameras shall
be as manufactured by Panasonic to match the City’s existing cameras. A Photometric plan shall be
provided to assess lighting levels for camera placement. The video will be sent via the communication
media to central control.
1.10.3 Site Electric Gates
Access to the site shall consist of two electrically actuated gates, one gate will be installed in the main
entry at the school parking lot and another gate will be located at the project site. Refer to Civil
drawings found in Appendix A, Section A-2 of Volume III-A for location of the gates. The gates shall
operate as follows:
Design-Build of North Torrance Wellfield Project Volume III – Contract Appendices
16 May 2017
The personnel use a proximity card to open the gate.
Security is disabled and the gate opens and then automatically closes after a time delay.
Upon exiting, personnel use proximity card or key switch to close gate.

Design-Build of North Torrance Wellfield Project Volume III – Contract Appendices
49 May 2017
demarcation pull box needs to be coordinated with the City. Modifications to the existing
City SCADA system are included in this the current project. See Appendix J of Volume
III-A for the pre-negotiated Scope-of-Work and fee to be incorporated in to the DB effort.
A design objective is to have all PLCs by Allen-Bradley Logix platform (ControlLogix
and/or CompactLogix).
Controls
Controls for manual and automatic equipment operation will be located in the MCC
compartment containing switchgear for the respective equipment. Minimum requirements
for equipment control are described herein under the section entitled "MCC."
Pumping units operating in the "auto" mode will receive the start/stop and speed signals
from the plant control system. PLCs will transmit alarm and status signals from remote
locations to the treatment plant SCADA and will receive control signals and set points for
pumping unit operation. All alarm, status, and control signal wires will be terminated on a
terminal block within the instrument control panel. If the PLC fails, the only mode of
pump operation will be manual via the pump HOA switch.
PLC
PLCs will receive all alarm and status signals and all analog signals from field
instrumentation. In addition, PLCs will provide output signals to the respective MCC
pump starter which will start/stop pumping units and cause pumping unit shutdown under
various alarm conditions (e.g., low flow rate, high discharge pressure, and low discharge
