Subject:Proposal for the Design of Three Fluoridation Facilities – SWA File: B.P. 20124015, Fluoridation
Dear Mr. Garrod:
The Sweetwater Authority (Authority) continues to embark on important projects to prepare our community
for future drinking water demand and quality issues. The fluoridation project is one of those important projects
that will contribute to protect the health of our community. In our proposal, we described how the Carollo
team will deliver the project by being open and responsive to Authority requests, while maintaining a strong
emphasis on project schedule.
The design of the three fluoridation facilities comes at a perfect time, not only for the assignment of Carollo’s
best chemical facility design team, but also at a time when getting competitive construction bids is at an alltime high. We recognize the importance of getting quality bid documents prepared in a timely manner to allow
the Authority to get funding and take advantage of the bidding environment. Carollo’s technical memorandum
(TM) review workshop will allow us to expedite the design.
As a local San Diego business, Carollo brings commitment, reputation, and in-house expertise to provide the
Authority with exceptional performance. We will build on Jeff Thornbury’s established relationship with the
Authority to develop a high level of trust with your staff and put our best foot forward to provide the Authority
with on-time, cost-effective solutions.
Our local San Diego office will enable efficient and effective joint planning and communications. To facilitate
communication, and a partnership approach, our project manager, principal-in-charge, project engineer, and
staff engineer are located in our local office.
This is an important project for the Authority and Carollo as partners in the community. We appreciate the
opportunity to provide this proposal to the Authority. We look forward to working with you and helping to
improve the quality of our drinking water in our community. If you have any questions regarding this proposal,
please contact Jeff Thornbury at 619-849-0642.
Sincerely,

PROJECT ORGANIZATION AND EXPERIENCE
We have carefully assembled our project team and
support team to meet the Authority's goals in terms of
design quality, construction cost, design schedule, and
communication.
Our local team, led by Jeff Thornbury, is familiar with
the Authority. Jeff's background working closely with
the Authority for the expansion of the Robert A.
Perdue WTP and the Richard A. Reynolds Desalination
Facility will facilitate communication during the
different phases of the fluoridation project.
Furthermore, our project manager, Jim Meyerhofer, is
recognized for designing chemical facilities that are easy
to operate and maintain (see below).
Our project team also provides the right combination
of technical expertise for the design of chemical feed
systems. Jim's extensive project management, risk
management, and civil experience, coupled with
Vincent's process mechanical and safety assessment
background, result in top-of-the-line chemical storage
and feed facilities.
The organization chart provided on the next
page identifies key personnel and their respective
responsibilities. Our support team includes individuals
that have worked with Jim and Vincent on previous
chemical system design projects, such as James Doering
(Structural), Harry Rice (HVAC), and Troy Hedlund
(Electrical, I&C). These projects, of similar nature, are
detailed on the following pages.
Key personnel resumes that highlight chemical system
design projects are included in the Appendix section of
the proposal. Table 1 on the following page summarizes
why our participation will make this project successful.
Table 2 on page 6 presents our team members

Our team members have focused their
careers on water treatment. Several
members of our team have worked together
on water related projects for many years.
This experience working together results in
a synergism that will contribute to deliver a
quality project to the Authority.
“Our Operations staff has also told me that the
Hemet Plant is the easiest of all our facilities to
operate and maintain, and much of the credit for
that is your team’s interaction with our O&M staff
to make sure they got what they needed to
maximize their efficiency.”

In 2003, EMWD retained Carollo to design a membrane filtration plant able
to produce water on an accelerated schedule of 32 months. The plant has
been in operation since September 2006. The plant current capacity is
12 mgd. The site build-out capacity is 40 mgd.
The plant includes a chemical building where the chemical feed systems are
located. The chemicals include: ferric chloride, sodium hypochlorite, caustic
soda, aqua ammonia, hydrofluorisilic acid, citric acid, and sodium bisulfite.
This design also included the design of the SCADA system, the piping
and instrumentation diagrams (P&IDs), and the control strategies. The
SCADA system is a ControlLogix remote input/output (RIO) system using
ControlNet redundant fiber optic ring topology, redundant servers and
backup, and Intellution FIX32.

The Naval Air Station Lemoore, California, is operating an 8-mgd
conventional WTP. In 2009, Reyes Construction and Carollo Engineers were
awarded a Design-Build (DB) contract to upgrade the supervisory control
and data acquisition (SCADA) system, improve the quality of the finished
water, and better control disinfection by-product (DBP) formation.
The initial Request for Proposal included transforming two existing abovegrade steel water storage tanks into a chlorine contact basin, and adding an
aqueous ammonia storage and metering facility. After carefully analyzing
the site and operations constraints, the DB team implemented the following
alternate engineering solution:
ff Constructing a new concrete chlorine contact basin with two chlorine
dosing locations.
ff Constructing a new ammonium sulfate facility.
The benefits of the innovative approach are multiple:
ff The storage capacity and the fire flow capacity of the distribution system
are maintained.
ff The rectangular serpentine-type disinfection basin presents a higher
hydraulic efficiency than the series of existing storage tanks; therefore, it
better minimizes DBP formation.
ff The second intermediate chlorine dosing point offers operations flexibility
and better DBP control for operation at higher water temperature or
lower flow.
ff Usage of ammonium sulfate avoids the operations and safety risks
associated with aqueous ammonia.
4
The disinfection basin is currently in operation and the tracer study required
by the California Department of Public Health has confirmed the design
criteria developed for the chlorine contact basin.
ff Design of a new chemical feed system that minimizes operational risk.
ff Design of new facilities that were built on an existing site without
impairing operations.
The project team (Jim and
Vincent) used 3D design to convey
the vision of the ammonium
sulfate facility to the client and
contractor.

The right level of effort applied to the development of
the TM enables the project team to deliver fluoridation
facilities that meet the stakeholders’ needs within the

us to be proactive and address the issues on time.
ff Meet the site constraints.
ff Be accurate and reliable.
ff Be safe to operate and maintain.
Project Management
Approach
Any design project is subject to the triple
constraint: Quality – Budget – Schedule. It is
important to acknowledge the constraint to
implement a project management approach that
maintains the quality of the deliverables within
the limits of budget and schedule. Thus, our
project management approach is based on the
following three principles:
ff Apply the right level of effort to the

For example, we will use 3D renderings to allow
Authority staff to visualize the new chemical
facilities without wasting budget and time in the
development and review of lengthy and sometimes
cumbersome write-ups.
ff Deliver what we promise. The “vision” selected
by the Authority as part of the TM effort will be
transferred to 2D drawings and specifications. This
is the most cost-effective approach for conveying
information to a contractor that results in
construction of fluoridation facilities that match the
Authority's vision.

Project Technical Challenges
The project team faces three challenges in designing the
fluoridation facilities. The design must:
ff Meet the site constraints.
ff Provide accurate and reliable chemical metering
systems.
ff Provide safe to operate and maintain chemical
feeding systems.
PROJECT APPROACH
Meet the Site Constraints
At water treatment plants, fluoride is added to the
water as one of the following raw chemicals:
ff Sodium fluoride
ff Sodium silicofluoride
ff Hydrofluosilisic acid
The flow range of the water treatment plants operated
by the Authority varies from 1 million gallons per day
(MGD) at the Wells Facility to 30 MGD at the Perdue
WTP. Thus, the three chemicals would be respectively
fed through the following chemical feed systems:
tote system would be installed to minimize the risk
of handling the highly corrosive acid. However, the
building operational state, the usage of ammonium
sulfate 50-pound bags, and the loading dock
configuration strongly suggest that the fluoride
raw chemical be delivered in 50-pound bags. Thus,
sodium fluoride is the leading candidate for the wells
facility.

ff The Robert A. Perdue WTP has been planned for
hydrofluosilicic acid. Sodium silicofluoride might
have been considered. However, all the other
chemicals used at the plant are liquids. Furthermore,
the fluoride raw chemical is to be stored outside
in a separate containment area. Thus, it makes
perfect sense to be using a liquid raw chemical and
hydrofluosilisic acid.
ff The National City Wells Facility has been planned
for sodium fluoride. Hydrofluosilicic acid might be
considered. It would allow the Authority to use the
same chemical at the three sites. Double stacked
PROJECT APPROACH
ff Even a drop of 0.2 mg/L below the optimal level can
reduce dental benefits significantly.
ff Fluoride above 2.0 mg/L and less than 4.0 mg/L –
the Maximum Contaminant Level (MCL) set in
the Safe Drinking Water Act – may result in dental
fluorosis in developing teeth.
To meet the accuracy challenge, the following actions
would be implemented:
ff Select the positive displacement metering pump so
it operates between 30-percent and 70-percent of its
stroke length.
ff Operate the metering pump against a fixed pressure
by installing a back-pressure valve on its discharge.
ff Install an anti-siphon valve upstream of the
chemical delivery point at the treated water line.
ff Meter neat chemical to prevent the uncertainty of
dilution and install a flow meter downstream of the
metering pump. The flow meter is installed upstream
of any potential carry-on water addition to the raw
chemical.
ff Install a fluoride analyzer on the treated water line.
ff Install an upflow saturator when using sodium
fluoride to obtain the same 4-percent solution
whatever the water temperature is.
The fluoride feed systems must be reliable too. The
desired level of reliability of the systems will be achieved
through the implementation of the following actions:
ff Install duty and standby metering pumps at the
three sites.
ff At the National City Wells Facility, install a softener
at the make-up water supply to the saturator.
The average hardness of 183 mg/L as CaCO3 is in
excess of the maximum recommended of 75 mg/L
as CaCO3. The approach will prevent the fluoride
ion from combining with calcium and magnesium
ions in the make-up water and formed precipitate
that can clog the saturator bed, and metering pump
suction line.
ff At the Robert A. Perdue WTP, install a utility water
softener for flushing water and carrier water to
prevent precipitation of silica and plugging of small
diameter pipeline.
ff At the Richard A. Reynolds Desalination Plant, use
reverse osmosis (RO) permeate water for make-up
water to the saturator or as flushing and carry-on
water.
above pump suction. The height of the vent riser
must be equal to the maximum friction loss in the
discharge pipeline downstream of tee plus two feet
of freeboard. The approach creates a fail-safe antisiphon device without any need for maintenance of
a valve.
ff Use of corrosive resistant materials. Examples of
such materials include PVC for pipelines and valves,
and Hastelloy C for wetted parts of field instrument.
ff Install flushing connections for the chemical lines.
Provide Safe to Operate and Maintain
Chemical Feed Systems
Both sodium fluoride and hydrofluosilicic acid present
potential acute health effects
ff Sodium fluoride can cause severe irritation to the
respiratory tract, if dust is inhaled.
ff Hydrofluosilisic acid is extremely corrosive to the
skin, eyes, or mucous membrane through direct
contact, inhalation, or ingestion. It must be handled
with extreme caution.
The acceptable level of safety will be achieved at each
site through the combination of the following features
ff For sodium fluoride,
–– Installation of local exhaust ventilation at each
upflow saturator to prevent dispersion of dust into
the work area and minimize operator exposure.
–– Use of coarse crystalline type sodium fluoride to
minimize dust production.
–– Use personal protective equipment including halfface dust/mist respirator.
ff For hydrofluosilisic acid,
–– Use of double-staked tote system to minimize
hydrofluosilisic acid handling.
–– Venting of the tote systems to outside of the
building to prevent accumulation of fume lighter
than air in the fluoride room.
–– Install ventilation air inlet grille low and exhaust
fan high.
–– Use personal protective equipment including
chemical splash goggles, and face shield.
ff When the fluoride is delivered to a tank operating
at atmospheric pressure such as a chlorine contact
basin, replace the anti-siphon valve with a vent
riser arrangement. The arrangement includes a tee
installed horizontal, and a riser connected to the
vertical branch of the tee. The height to centerline
of tee above centerline of pump suction must be
greater than the height of liquid in the storage tank

Richard A. Reynolds Desalination Facility Expansion, Sweetwater Authority, Chula Vista, California
The Richard A. Reynolds Desalination Facility treats brackish groundwater produced from the Authority’s San
Diego Formation wells for potable use. CH2M HILL was retained by the Authority to develop the preliminary
design concepts and the final design to expand the Reynolds Facility treatment capacity from 4 mgd with its
existing three membrane trains to 10 mgd with three new membrane trains and 1 mgd of bypassed and reblended flow. The groundwater has high concentrations of iron and manganese. CH2M HILL designed a Pyrolusitebased, high-rate media filtration system to remove the iron and manganese in the bypassed flows under a
separate project.
The preliminary design recommended the installation of three
new RO trains with a total permeate production capacity of 5
mgd (1.67 mgd each), using membrane elements with a
membrane area of 430 or 440 square feet in a 24:12 pressure
vessel array. CH2M HILL also recommended the installation of
inter-stage boosters for the existing and new RO trains to
recover energy and to improve process performance. In
addition to the new RO trains, the project included:


stopped due to grant funding issues.
Project Cost: $590,000 (Fee)
In addition to the expansion of the membrane process, the
project also included the evaluation of membranes, tested by the Authority, to recommend replacement
membranes for the existing three RO trains and for future purchase for the three new RO trains. CH2M HILL
prepared procurement documents that the Authority used to pre-purchase new membranes for the facility. Toray
TMG20-430C membranes were selected as the replacement based on competitive bids.
Dissolved Air Flotation (DAF) System Retrofit, Sweetwater Authority, Chula Vista, California
CH2M HILL has been retained by the Authority to design a DAF system for the Authority’s Robert A. Perdue WTP.
The DAF system is to be retrofitted into the Perdue Plant’s existing sedimentation basins and is to have a
maximum hydraulic capacity of 40 mgd. A preliminary design was completed that evaluated high-rate versus
conventional rate DAF processes. The pre-purchase of a high-rate DAF system was recommended to meet the
project treatment objectives and regulatory compliance requirements.
Based on the preliminary design recommendations, CH2M HILL prepared a prepurchase package to solicit bids for
the project DAF system equipment. The prepurchase package included contract front-end documents, technical
specifications, and general process layout and Piping and Instrument Diagrams. The ITT Leopold DAF system was
selected from the bid solicitation, and the project final design is being developed around the Leopold DAF system
with hydraulic solids removal. The solids storage compartments are being incorporated into the existing
sedimentation basins, and submersible pumps are being used to pump the solids to downstream processing.
Submersible pumps installed into the treated water compartments are being used to recycle treated water to the
two process saturator tanks. The DAF system will have an 8 gallon per minute per square foot (gpm/sf) hydraulic
surface loading rate and a 10 percent maximum recycle rate. In addition to the DAF system, the project design
included the following items:
Structural modifications to the existing flocculation/sedimentation basins to convert them into four separate
treatment trains;
 Replacement of the existing flocculation equipment with new flocculation equipment with VFD drives’
 DAF process building that houses the process electrical equipment and air compressor system;
 Sun shade type cover for the DAF process;
 Standby generator system; and
 Expansion of the plant 12 kV electrical and fiber optic

The prepurchase of the DAF system required the equipment supplier to pilot test their process to demonstrate
that the process is capable of meeting the specified treatment performance requirements. CH2M HILL developed
the pilot testing plan and assisted the Authority in evaluating process performance and preparing a final pilot
testing report.
Twin Oaks Valley Water Treatment Plant
The San Diego County Water Authority (SDCWA) awarded the
design, permitting, construction, and long-term operations of
the new, 100-mgd Twin Oaks Valley (TVO) WTP to CH2M HILL
in September 2005, the first of its kind: largest submerged
membrane plant in the world at completion, serving
approximately 220,000 households per year. CH2M HILL
designed and constructed the treatment plant and is
currently operating and maintaining the facility for a period of
20 years. The single integrated Design-Build-Operate delivery
contract included $159 million for design, permitting, and
construction plus operations and maintenance.
A key component of the Twin Oaks facility is the
Untreated Water Pump Station, which has a capacity of 110 mgd. Designed with five vertical turbine pumps at 500
hp each, flow can be provided with one pump out of service to ensure the required flows can be delivered at all
times. The submerged membrane facility is at the core of the treatment. Primary disinfection for the membrane
permeate is provided by application of ozone followed by biologically activated contactors. If needed, the ozone
system can operate in advanced oxidation mode with the addition of hydrogen peroxide to address potential
taste and odor issues. An onsite sodium hypochlorite generation system provides chemicals for maintaining
distribution system residual. In addition, seven other chemicals are stored and operated to achieve the water
treatment goals, including a fluoroscilisic acid system for treated water fluoridation.
A 10 mgd residuals system consisting of equalization, chemically enhanced lamella plates settling, gravity thickening, and
centrifuge dewatering, achieves greater than 20 percent residuals solids concentration. The TOV WTP is designed to be a
no discharge facility, with recovered water returned back to the head of the liquid treatment process.
In a 2012 follow-up project, CH2M HILL provided preliminary design of facilities for delivery, conditioning and
blending of desalinated water from the Carlsbad Water Treatment Plant with the TOV WTP effluent. The facilities
consist of 54-inch desalinated water conveyance coming into the TOV WTP, flow metering facilities, sodium
hypochlorite and ammonia addition for boosting of chloramine residual in the desalinated water, and water
quality monitoring. The desalinated water is blended with the TOV WTP water in the existing clear wells.
Computational fluid dynamics modeling was used to model the clearwell inlet/outlet configuration and hydraulics
to ensure that fully mixed desalinated water and TOV WTP effluent is achieved prior to the distribution system.
The improvements also include upgrades to the existing treated water flow control facilities to increase the
capacity of the blended treated water output from the TOV WTP to a combined 150 mgd.
CH2M HILL’s delivery of the Twin Oaks facility has been recognized with several local and national industry
awards, including:

were evaluated, including fluorosilicic acid, sodium fluoride, and sodium fluorosilicate. Applications ranged from
less than 500 gpm (0.7 mgd) to 10 mgd. Each fluoridation alternative was evaluated for general product
information, source/availability, storage and feed requirements, equipment requirements, regulatory compliance,
and safety. A decision evaluation was completed, including non-monetary considerations and present worth
costs. Recommendations were presented for small-, medium-, and large-system applications.
Fluoridation Study; Salt Lake City Department of Public Utilities; Salt Lake City, Utah. CH2M HILL managed a
comprehensive evaluation of existing fluoridation systems and procedures and provided recommendations based
on the project findings. The SLCDPU fluoridation system included 16 remote installations, as well as three, large
centralized water treatment plants. In particular, the scope of the work was primarily focused on providing
recommendations to SLCDPU for minimizing accidental releases of fluorosilicic acid. The work included review and
evaluation of standard operating procedures, identification of design improvements; improvements to the SCADA
system for better operational, monitoring, and safety features; and review and evaluation of multiple emergency
response procedures.

Proven Leadership – Our experience has shown that the single greatest factor in the
success of any project is the expertise and commitment of its leaders. We have dedicated
one of our top design managers, Bill Moser, for the Fluoridation project. He has 40 years of
experience, and has completed numerous water supply projects, working from the
conceptual level through start-up of the facilities.
Proven Local Team – Assisting Bill will be a team of technical experts based locally in
Southern California. James Borchardt will provide technical support and serve as Principalin-Charge. Our team has been very efficiently organized for the Fluoridation project, and all
team members have a thorough understanding of the Authority’s design standards and
facilities. Our team members have successfully worked together on numerous water supply
facilities and have just recently completed the design for the Perdue Water Treatment Plant
Chemical System Upgrades. Selection of this cohesive, experienced team will result in
significant time and money savings.
Our Approach – It will be essential that the fluoridation facilities meet Authority goals for
safety, control, and accuracy of the fluoride concentration in the water. Additionally,
selection of standardized equipment at the treatment, desalination and well facilities will
promote operational and maintenance consistency.
MWH is excited about the opportunity to work with the Authority on this important project. We look
forward to meeting with you to discuss any questions you may have regarding this proposal. If you
have any questions or require additional information, please contact our Project Manager, Bill Moser,

Project Team
We have selected a locally-based team with
experience at the Authority’s water treatment
facilities and fluoridation facility designs. The
core team recently completed the chemical feed
facilities upgrades at the Authority’s Perdue
Water Treatment Plant, where facilities were
designed to accommodate future fluoride feed
facilities.
William Moser, PE will be our Project Manager.
Bill has worked with the Authority for over 20
years, most recently serving as Project Manager
on the Perdue Water Treatment Plant Chemical
System Improvements and serving as Master

Experience and Qualifications
MWH has extensive local experience with the
design of fluoridation facilities for municipal
drinking water systems. We have designed
fluoride facilities for both water treatment plants
and well sites. We have designed liquid and dry
fluoridation systems.
MWH has learned valuable lessons from our past
projects and we continue to increase our
familiarity with important fluoridation issues
through our current projects that are in design
and construction. We have the advantage of
being able to leverage our current work on very
similar projects to assist us in efficiently
completing the Authority’s Project. For example,
we have recently reviewed the pros and cons of
the typical fluoride chemical forms, developed
SEPTEMBER 2012
|2
calculation spreadsheets, and designed and
drawn fully detailed fluoridation systems that will
allow us to concentrate on issues unique to the
Authority rather than general fluoridation issues.
We have also worked with the California
Department of Public Health (CDPH) on the
fluoridation issue and have a good sense of the
design elements and operational procedures they
expect to see in fluoridation systems.
MWH knows that a clear understanding of all
costs associated with existing and alternative
fluoridation facilities will be important to the
Authority. We have pricing and vendor quotes
from current fluoridation projects that will assist
us in accurately capturing costs. We also have
experienced in-house estimators from our
construction group who have cost estimates from
several recent projects to validate costs
developed for this project.
Project Understanding
Approach
MWH’s approach is based on our experience on
similar projects, our familiarity with the key issues
involved with fluoridation systems, and our
knowledge of the Authority’s system. We will
prepare a Preliminary Design Criteria Technical
Memorandum that defines the required elements
of the project and selection of alternatives before
starting the final design phase. Our project
understanding and approach is based on meeting
the Authority’s goal for safety, control, and
operational and maintenance efficiency as
presented in Section 4.

The facilities were designed to use the plant
softened water supply to dissolve solid sodium
fluoride in saturation tanks, and then pump the
saturated water to one of the feed points within
the plant’s process train. The primary feed point
is to the raw water, prior to membrane filtration.
This allows the fluoride feed to be flow-paced,
mixed, and continuously monitored. The second
feed point for treated water was planned for
future use, when other planned improvements
would allow flow-pacing, mixing and monitoring.
The facility design included:
•

Sacramento County Water Agency
Fluoridation Project
In spring 2008 Sacramento County Water
Agency retained MWH to prepare a preliminary
and final design for the addition of fluoridation
treatment systems to the Agency’s 23 existing
well pump stations and 9 existing water treatment
plants. As the design progressed, the scope of
work was expanded to include upgrades of the
existing chlorination systems at many of the
treatment plants, as well as chlorination
equipment replacement at nearly all of the well
sites.
MWH has conducted the planning and design of
fluoride feed facilities at water treatment plants
and well pump stations throughout California.
San Juan Water District Fluoridation
Feasibility and Project Cost Report
SJWD retained MWH in early 2009 to investigate
the feasibility and potential costs associated with
fluoridating the potable water it provides to its
wholesale and retail customers. The feasibility
evaluation included a 120-MGD-capacity water
treatment plant and a total of 52 wells owned by
SJWD’s wholesale customers.
The project included a review of water production
and water quality data as well as existing design
drawings. The three common fluoride forms
(sodium fluoride, sodium fluorosilicate, and
fluorosilicic acid) were evaluated to determine
their suitability for use at the project facilities.
Advantages and disadvantages of each of the
chemical forms were discussed. Separate
evaluations were performed for the water
treatment plant and the well sites due to their
different flow rates, site constraints, and O&M
requirements. Two alternative fluoridation design
approaches were developed for both the water
treatment plant and the well sites, and a
preferred design was selected for each.
MWH prepared feasibility-level design layout
drawings for the water treatment plant and for a
“typical” well site. Piping and instrumentation
drawings were also prepared for the two
representative designs. MWH next prepared
capital and O&M cost estimates for the two
designs. The O&M costs included all “real world”
O&M activities and replacement costs and
effectively captured the true cost of maintaining
the proposed systems.
The design consists of the addition of
prefabricated buildings housing the chemical
storage tanks and feed equipment, new
analyzers, new or rerouted sample piping, and
additional monitors and alarms for the existing
chlorination systems. Process chemicals consist
of fluorosilicic acid and sodium hypochlorite,
which will be used for fluoridation and
chlorination of the treated water. The new
systems will be integrated with the existing
programmable logic control (PLC) system at each
site to interact with a remote supervisory control
and data acquisition (SCADA) system, which is
currently being designed and installed by the
Agency.

Sacramento River Water Treatment
Plant
The In 2004, MWH completed an expansion to
the Sacramento River Water Treatment Plant
(SRWTP) from 100 to 160 mgd. The SRWTP is
believed to be the oldest publicly owned water
system west of the Mississippi River.
The plant has been through several expansions,
including the addition of eight filters in 1928, a
SEPTEMBER 2012 | 12
second pretreatment train in 1933, and a 9.5-MG
reservoir in 1937, 100 to 160 mgd. To obtain the
the 160 mgd capacity, a grit basin, flash mix, and
flow split structure was designed and
constructed. Additional structures that were
added include a flocculation and sedimentation
basin, a filter complex, a chlorine tank and
clearwell, an 11,000 square foot operations
building, a chemical building, and concrete-lined
filter waste wash water and solids holding basins.
Also, the team made chemical feed
improvements and structural modifications to the
existing 1924 coagulant building. A new plant
SCADA system for new and existing processes
was also designed and constructed.
In 1999, MWH performed services from
preliminary design to construction management
for the temporary retrofit fluoridation system at
SRWTP. Although the City was moving forward
to incorporate a permanent fluoridation facility as
part of the plant expansion described above,
expediting this part of the project was paramount;
therefore a temporary fluoridation facility was
designed and constructed.
Waterman Water Treatment Plant
Expansion and Modernization Project
The City of Fairfield retained MWH to provide
predesign, design, and construction management
services for expansion of the Waterman Water
Treatment Plant. The project will expand the
plant’s capacity to 30 mgd from its current
capacity of 15 mgd. The project will include
construction of new ballasted flocculation (Actiflo)
and expansion and rehabilitation of the existing
dual media filters. The project also will include
construction of a new chemical storage and feed
building, a new pump station, new washwater
equalization basins, new sludge clarifiers, a new
sludge lagoon, and expansion and modernization
of other phases of the treatment system.

City of Roseville Diamond Creek
Pump Station
MWH performed design and construction support
services for both phases of the City of Roseville’s
Diamond Creek Well Pump Station project.
For the first phase, MWH designed and provided
construction support services for the construction
of a 2,700-gallon-per-minute injection/extraction
well pump station with chlorination disinfection.
The pumped well water was disinfected by
means of a manually mixed calcium hypochlorite
solution and an automatic chlorination delivery
system. Roseville also wanted the ability to
switch over to a more self-sufficient chlorine
generation system in the future as water
demands increased, and the well was to be
operated continuously. In addition, Roseville
wanted to be able to add a fluoridation system
using sodium fluoride in the future. MWH
developed an economical design that allowed
them to install a manually mixed chlorination
system with the ability to switch over to chlorine
generation at a later date, and add on a fluoride
treatment system, without major modifications
caused by the conversion.
The design work included relocating all of the
plant’s chemical storage and feed components to
a single structure. The new chemical storage
and feed building included facilities for
Hydrofluosilicic Acid, Sodium Hypochlorite, Alum,
Caustic, Calcium Thiosulfate, and polymers. The
design included new storage tanks and metering
pumps for all chemicals and routing of new
chemical feed piping throughout the plant site to
the various injection points. The project is
presently under construction and MWH is
providing full construction management services.

Project Understanding and Approach
Our approach is based on meeting the Authority’s goals for safety, control, and
operational and maintenance efficiency.
With funding provided by First 5 Commission of
San Diego County, the Authority plans to
fluoridate its water supply. The Authority will add
fluoridation facilities to three sources of supply:
the Perdue Water Treatment Plant, Reynolds
Desalination Facility and National City Wells
Facility.
The MWH proposal for the Authority’s fluoridation
project includes providing engineering planning,
design and bid support services as described in
the Request for Proposal (RFP). MWH is
committed to fully support and advance the
project through design completion and successful
facility operation. Our approach to the project is
presented below, followed by an outline of our
proposed work plan.
and a sprinkler system may also be required
depending on the volume of acid stored at each
facility. We will provide appropriate warning
signage and an alarm to detect any fluoride
leakage into the secondary containment area.
Hydrofluosilicic acid is also corrosive to glass as
well as metals so materials of construction must
be selected carefully. MWH is very experienced
in designing fluoride systems and will
recommend appropriate materials. Storage and
day tanks should be constructed of cross-linked
high density polyethylene while piping should be
PVDF or PVC.
Project Understanding
Based upon our experience in the design of
fluoride feed systems and our familiarity with the
Authority’s facilities, we have identified four key
goals critical to the success of the project:
•
Provide for safety of workers and
facilities
•
Provide for control and accuracy of the
fluoride dosing
•
Standardize equipment to facilitate
maintenance and operation
•
Establish stakeholder consensus for
design concepts and criteria
Safety of Workers and Facilities
Hydrofluosilicic acid is a highly corrosive
chemical. MWH will layout the facilities to
minimize potential worker contact with the acid.
In addition to shower/eyewash stations, adequate
ventilation must be provided for worker safety
and to protect equipment and materials. The
fluoride facilities should be separated and
isolated as much as possible from existing
treatment plant ventilation systems. Secondary
containment is required for hydrofluosilicic acid
Corroded fluoride tank
Hydrofluosilicic acid has a pH of approximately
1.2 and can depress the pH of the treated water
which may in turn cause internal pipe corrosion
or leaching of lead and copper into the water.
The pH depression is not expected to be a
significant issue, but MWH will confirm this during
design. The injection system will also be
designed to promote thorough and rapid mixing,
perhaps through the use of carrier water for the
acid, to avoid allowing a concentrated stream of
acid to contact the pipe.
SEPTEMBER 2012
| 14
Control and Accuracy of Fluoride
Dose
While fluoridation of drinking water improves
overall dental health, over-dosing or underdosing fluoride can be harmful. The California
Department of Public Health (DPH) defines an
optimum fluoride concentration and associated
control range based on average maximum daily
temperatures. The amount of fluoride added is
adjusted depending on the concentration of
naturally occurring fluoride in the water. Daily
treated water samples must be tested for fluoride
concentration and reported to the DPH. MWH’s
design for all facilities will include measures to
ensure the amount of fluoride added to the water
is appropriate and the desired fluoride
concentration is achieved in the treated water.
The Authority will want to be particularly confident
that the fluoridation dosing systems are operating
properly. To prevent over-feeding fluoride, MWH
will provide an intertie between the metering
pump and the supply to assure that fluoride can
only be added to the water distribution system
when the system is running. To confirm that the
water has been dosed properly a fluoride residual
analyzer will be located downstream of each
injection location. It is critical that each analyzer
gets a good representative sample. Depending
upon the piping arrangement and the distance
from the point of injection to the analyzer, a
carrier water system for acid injection may be
required to assure a representative sample. The
analyzers will be provided with both high and low
fluoride concentration alarms to SCADA. The
system can also be designed to shut down the
supply if a dangerously high or low fluoride
concentration is detected by the analyzer. The
hydrofluosilicic acid storage tanks may also be
provided with both high and low level alarms to
prevent over-filling and potential under-feeding,
respectively.
Standardize Equipment to
Facilitate Maintenance and
Operation
The Perdue water treatment plant, desalination
plant and well site may benefit from
standardization of equipment. MWH would
typically recommend a two-pump, duty/standby
arrangement to facilitate rapid response to pump
problems. Although a metering pump could be
optimally sized for each situation, the Authority
may want to standardize on a pump that is
capable of performing at the higher flow locations
and use the same pump at the lower flow
locations. Current metering pumps can easily
achieve the flow turndown required and this
would aid in maintenance and operational
consistency. Similar to metering pumps, MWH
can assist the Authority in the analysis of the
costs and benefits of selecting a smaller number
of standard tank sizes that can cover the range of
storage requirements.
MWH’s fluoridation system design will
incorporate the SCADA design and integration
criteria from the Authority’s SCADA consultants,
Enterprise Automation and Timberline
Engineering to maintain standardization.
Instrumentation and equipment will be tagged
following the conventions established as part of
the Authority’s SCADA system requirements.
SCADA operators will receive system information
and have the ability to manipulate setpoints as
done with other chemical feed systems.
Information on SCADA will include pump status
and chemical storage status. Operator setpoints
will include dosage setpoints and residual
setpoints.
Example layout for tank, transfer pump, batch
tank and chemical feed pumps
Establish Stakeholder Consensus
for Design Concepts and Criteria
It is critical to a successful project that all
stakeholders, including engineering, operations,
and maintenance staff, concur that the final
design meets their overall design criteria and
functional requirements. A key to building
consensus is to have all elements of the design
diligently researched and clearly presented to all
parties. MWH will conduct a thorough review of
all available water quality and existing facility and
design data and will also conduct site
investigations. We will then work collaboratively
with the Authority to develop overall design
criteria for the project, culminating in completion
of the final design.
SEPTEMBER 2012
| 15
MWH will work diligently to obtain buy-in from
engineering, operations, and maintenance staff at
all design levels to assure the project stays on
schedule and to avoid inefficient design changes
late in the project. We will continue to hold
routine coordination meetings and design review
workshops through to successful completion of
design.
Project Approach
Our approach has been organized into five main
tasks, as presented in the below. Our fee
estimate and hourly labor is detailed in the cost
proposal submitted in a separate, sealed
envelope in accordance with the instructions
stated in the RFP.
Bill Moser, Project Manager, will be responsible
for implementing the work tasks within the
established budgets and schedules. He will
interact with the Authority’s project manager and
staff to fulfill the requirements of specific tasks.
As Project Manager, Bill will also be responsible
for planning QA/QC activities. Mr. Moser will
prepare a Project Execution Plan and work
breakdown structure (WBS) to provide a concise
outline of the scope of work. The WBS is the
organizational framework by which Bill can create
and display the breakout of project
tasks/subtasks and deliverables, monitor and
update progress made on specific tasks, review
budgeted costs or revenues, and monitor earned
value job progress parameters.

reduce rework and produce deliverables on
schedule and within budget. The primary
elements of the project management task are:
•
Schedule and budget control
•
Quality assurance/quality control
(QA/QC), including: preparing a
Project QA/QC Plan, establishing
technical review meetings, and
assuring compliance with the
QA/QC Plan
•
Coordination with the Authority and
others regarding Project issues
•
Overall management of the
consultant team, including staffing,
resources, technical review of work
products, preparing invoices,

Our Project Manager has access to weekly
updated cost information to monitor actual
expenditures against project progress. Costs are
monitored weekly and Earned Value and
estimates to complete are prepared monthly.
The objective of the project management task is
to manage our resources such that the Project is
executed in accordance with our agreement with
the Authority, and to communicate project
progress and issues to stakeholders.
Task 2 –Meetings
Key team members from MWH will conduct a
kickoff meeting with the Authority to establish
lines of communication, verify responsibilities and
confirm the Project mission, objectives, scope,
and schedule. This meeting will also be used to
discuss with Authority staff O&M issues
associated with the proposed fluoridation system.
A site visit to the Authority’s the Perdue Water
Treatment Plant, Reynolds Desalination Facility
and National City Wells Facility will follow directly
after the meeting. MWH will provide a list of data
needs at this meeting to expedite the process of
data collection and review.
SEPTEMBER 2012

MWH will attend four submittal comment review
meetings to discuss and review the Preliminary
Design Criteria TM, 30%, 60% and 90% design
submittals. One SCADA coordination meeting
will be held to verify the control standards and
requirements for equipment for the Authority’s
fluoridation system. Technical meetings as
requested by the Authority staff may also be held.
equipment, and feed pump sizing will be
considered in the design.
MWH will prepare the draft Preliminary Design
Criteria Technical Memorandum and will make
one presentation at a submittal comment review
session. MWH will review and incorporate
Authority edits to the draft report and issue a final
Preliminary Design Criteria Technical
Memorandum.
Task 4 – Fluoridation Facilities
Design Deliverables
Chemical metering pump and appurtenances
Task 3 – Preliminary Design
Criteria Technical Memorandum
The objective of this task is to outline and
establish the basis of design for the three
fluoridation facilities. MWH will obtain existing
water quality data from the Authority. MWH will
review all existing treatment and well facilities
information and drawings to determine the
fluoridation systems and operations that provide
the optimum safety, system performance and
minimized O&M costs to the Authority.
Three chemicals, sodium fluoride, sodium
silicofluoride (Na2SiF6), and fluosilicic acid
(H2SiF6), are the most common compounds
used for the fluoridation of drinking water. The
first two chemicals are available in powder or
crystalline form while the third is available in
liquid form. There are pros and cons to the use
of each chemical form. MWH will determine the
most appropriate chemical form to be used at
each of the Authority’s water supply facilities
We will develop a basis of design Technical

Site plans with conceptual layout of
structures
•
Mechanical plan and section
•
P&ID’s and control descriptions
The MWH Team understands that optimum
design is crucial to the long term success of the
project for both the ease of operation of the new
facilities and to meet the Authority’s goals. While
providing functional and cost effective fluoridation
facilities is key to this project, the balance of work
is the design of the chemical storage, metering,
piping and controls. This could be considered
“straight forward” engineering, but still requires
technical experience and knowledge of the
Authority’s facilities.
We also envision a workshop will be held during
the design development. The goal is to seek
input from operations personnel on preferred
control methods, types and locations of valves
and meters, and the level of remote monitoring
and control to be built into the system.
The MWH Team will design to Authority and
industry standards. The layout of the fluoridation
facilities will consider the size of all equipment,
access around the equipment for maintenance
and operation of the facility and operator safety.
MWH will prepare “Class 3 and 4” level Opinions
of Probable Construction Costs (OPCC) for the
required fluoride facilities at the 60% and Final
submittal levels, respectively. OPCC’s will be
prepared in accordance with the cost estimate
classes, as defined by the Association for the
Advancement of Cost Engineering.
The MWH Team envisions design submittals will
be provided at the 30%, 60%, 90% and final
design levels. The following lists outline typical
deliverables in each submittal package.

understanding of the regional and local needs and goals. He currently serves as a senior project manager
in the MWH San Diego Regional Office. His primary responsibilities include management of major
technical projects.
Relevant Project Experience
P-1045 RFP Development, NAVFAC, Marine Corps Base Camp Pendleton, CA
This purpse of this project was to develop 60% drawings and specifications for 24 miles of HDPE
domestic water pipeline, two pump stations, and a 3 MG reservoir. Notable challenges include a river
crossing, working in environmentally sensitive areas, tank crossings, challenging operational conditions, a
railroad crossing, a highway crossing, and bridging two pressure zones. Mr. Moser served as project
manager and served as the technical lead. Work elements consisted of coordination of four
subconsultants, MWH staff, five disparate engineering disciplines, and meeting challenging environmental
constraints.
Robert A. Perdue Water Treatment Plant, Sweetwater Authority, CA
Mr. Moser served as project manager on the original project to add pre-treatment facilities at this 30-mgd
plant. More recently he served as Project Manager for upgrades to the chemical storage and feed facilities
and to add variable frequency drive on the raw water pump station. Facing compliance concerns, Mr.
Moser worked with the Sweetwater Authority to assist in selecting a process train that would ensure
regulatory compliance well into the future and address other water quality concerns.
Upgrade and Expansion of the Badger Water Treatment Plant, Santa Fe Irrigation District/San
Dieguito Water District, CA
Mr. Moser assisted in the expansion of this 40-mgd conventional water treatment plant that serves the
San Dieguito Water District and the Santa Fe Irrigation District, located in the north coastal area of San
Diego County. Mr. Moser’s responsibilities included the construction oversight of new filters,
improvements to the chemical feed and storage facilities, and a chorine scrubbing system. More recently
he provided as-needed engineering and design services for a variety of projects at the water treatment
plant.
Otay Water Treatment Plant Expansion, City of San Diego, CA
Mr. Moser managed the expansion of the Otay plant to 40 mgd. The project included replacement of the
circular clarified with rectangular flocculation and sedimentation basins, eight new filters, new chorine
storage and feed building, and expansion of the administration/laboratory building. Mr. Moser served as a

Water Distribution Master Plans, Multiple Clients, CA
Mr. Moser served as project engineer for water distribution master plans for: Ramona Municipal Water
District, Sweetwater Authority, Otay Water District, Santa Fe Irrigation District, City of Escondido, and San
Dieguito Water District.
Project Manager, Otay Water District North/South Interconnection Preliminary Study
Mr. Moser was the project manager and primary analyst for the preliminary study to assess the pipeline
and pump station alternatives to connect the District’s North and South service areas. The study also
evaluated the facilities needed for an emergency connection to the Sweetwater Authority’s Perdue WTP.
The product is a preferred pipeline alignment, potential locations for pump station(s) and pump selection.
Mr. Moser’s knowledge and experience for the preliminary study make him an excellent candidate to be
the District’s project manager on this next phase of the project.
Project Manager, Otay Water District, General Consulting
Mr. Moser was the project manager for a three year as-needed contract with the District. He provided
technical review and input on various potable and recycled water system issues raised by the engineering
staff. An economic analysis was prepared for the purchase of recycled water from the South Bay
Reclamation Plant for the then current and proposed rates. These were compared to the option of using
imported raw water in place of the recycled water. A variety of options for constructing emergency
connections to neighboring water agencies were analyzed. These analyses led to the option for the
emergency connection to SWA that is part of the North/South Interconnection Project.
Principal-In-Charge, 450-1 Reservoir and 680-1 Pump Station, Otay Water District
Mr. Moser was responsible for the conceptual development of the pump station. He led a technical
analysis of the recycled water distribution system. He recommended increasing the size of particular
planned pipelines, which resulted in significantly reducing pumping unit size (horsepower). This resulted in
a decrease to the construction and operating costs of the facility.
During the design phase, he provided technical oversight as a member of the technical review committee
(TRC). He was responsible for pump selection, and review of the pump station’s physical and mechanical,
equipment selection, and operating guidelines.
Principal in Charge, Design of Los Coches Pump Station, Helix WD
Mr. Moser was responsible for the conceptual design of the pump station, including pump selection and
the number of pumps to provide 64-mgd capacity. He worked closely with District staff, who had the
hydraulic analysis model of the transmission system to develop the system demand curves to facilitate
pump selection and define the operational control methods.
During detailed design he provided technical assistance to the PM and design disciplines and served on
the technical review committee responsible to review plans and specifications prior to each progress
submittal.
Project Manager, Harold Ball Pump Station Electrical Upgrade Project, Helix WD
Mr. Moser prepared a feasibility study that examined options to replace two diesel engines; each drive a
45-mgd pump in the station, constructed in 1985. The existing engines could not remain in service due to
changing air quality regulations. Options included new diesel engines or electric motors. The
recommended solution was to install a 700-horsepower electric motor on each pump and provide variable
frequency drives.
During design, Mr. Moser led the design team of mechanical, structural, electrical, and instrumentation
engineers in the preparation of the plans and specifications for necessary modifications. He managed all
technical aspects of the project and monitored all aspects of schedule and budget. The project design was
completed on schedule and under budget.
Principal-in-Charge, San Vicente Surge Control Facility and San Vicente Pipeline, San Diego
County Water Authority
Mr. Moser provided technical oversight to the project design team. He provided technical input during the
planning stage and preparation of the steady state and transient hydraulic analyses that led to the addition
of the Surge Control Facility (3.3-MG tank on the discharge side of the pump station). This included the
San Vicente Tunnel and San Vicente Pump Station. During detailed design, he provided technical review
of the hydraulic calculations and sizing of all elements (pipelines, reservoir, etc.).
Project Manager, SDCWA Pipeline 6 Study, San Diego County Water Authority
Mr Moser was responsible for technical direction for a comprehensive one-year long study of four
potential alignments for an extension of a 120-inch diameter pipeline in northern San Diego County. He
led the effort to define what alignments would be considered based on past studies, the location of
existing pipeline and ROW, and what alignments were being considered by the Metropolitan Water District
(MWD) for their reach of the overall project. Plan and profile engineering drawings were prepared for each
alignment ranging in length from 58,000 feet to 92,000 feet. A steady state hydraulic profile was prepared
for each so that pipe thicknesses could be calculated and the potential to generate power could be
estimated.
Design of The 42 to 48-inch Diameter Flume Replacement Pipeline, El Cajon, CA
Mr. Moser oversaw the planning, design, and construction management of the 42- and 48-inch diameter
Flume Replacement Pipeline for Helix Water District. This project was the last link in the District’s
replacement program for the replacement of a decades old gravity flume.
