Ken Reed I ( 209) 992- 7363 I kreed@ci. Iathrop. ca. us Re: Professional Design Engineering Services Proposal for the City of Lathrop CTF WRF Phase 4 Expansion Design
Dear Ken,
Over the last 10 years, we have worked together to complete Phases 2 and 3 of the CTF facilities and optimize the equipment and process operations.

As the facility inflows have increased, we have transitioned to four trains and teamed to provide the dechlorination facilities that have been operating for three years. Moving forward, we are excited to team up again on the Phase 4 CTF Expansion to bring the facility to the full build - out capacity of

6. 0 MGD, which will include another pair of biotrains comparable to the Phase 2 and 3 designs. The Phase 4 system will transfer flows in/ out of the Phase 2 and Phase 3 systems to create homogenous activated sludge and MBR filtration.

The Phase 4 expansion proposed is based on careful planning and organization established in Phases 2 and 3. The Phase 4 design will include the final headworks expansion, splitting of the inflows to all three pairs of trains, re -combining at the downstream end, new air equipment, and new MBRs.

Thank you for this opportunity, and we look forward to kicking off Phase 4 together and working toward another successful project at the CTF.

PACE
introduction
INTRODUCTION // 1
In 2015, PACE had the unique opportunity to design the Phase 2 expansion ofThe City of Lathrop CTF, which was successfully constructed at budget and has produced excellent water quality under varying infuent conditions. In 2020- 2025, PACE provided additional upgrades that positioned the facility' s phased expansions and the final Phase 4 expansion to the build - out capacity. Due to rapid City development, the facility receives load at over 50% of the rated capacity, and is scheduled for the Phase 4 expansion to bring the facility to its build -out capacity of 6. 0 MGD. This proposal outlines the approach and scope for this important expansion.

PHASE 4
The current MBR treatment facility is well -organized,
flexible, and operationally efficient. It was designed with expansion in mind, and this expansion will include a
Phase 4 facility that will be the final version of the build - out plant. The proposed Phase 4 treatment structure will be located to the east of Phase 2, which means it will
effectively function as the final system of the wastewater process flows. Flows will be transferred back and forth between Phases 2 and 3 during normal operation. Also
importantly, this Phase 4 expansion will consolidate the headworks, the aeration air system, and the MBR air
scour system into one system to avoid having multiple
groups of equipment performing the same function.

As stated during Phases 2 and 3, the key to a successful project will be to effectively and cost - efficiently lay out improvements to take advantage of existing works, while at the same time transitioning the facility to larger, more organized blocks of unit treatment processes that are
easy to understand and access, and of larger capacity
that are easily expandable. We will continue with the
primary philosophy to provide accessible tanks with
minimal equipment to simplify operations. EXIST. EMERGENCY oF, EN. p, as, N

PROPOSED
PHASE 4
PACE has retained the same team of professionals as Phase 2 and 3 that will again focus on the constructability, long- term ease of operation, and minimized operation and maintenance costs, while providing high water quality. We have again assembled a complete team that has the ability to take the City from initial concepts, through design, bidding, and beyond if requested, including construction, startup, and post start- up support services that will make sure that all of the City' s goals are achieved.

Our team has recently completed several successful plant expansions where operations during construction were managed effectively and the final outcome was a straightforward and highly operable facility. These include the 5. 4 MGD Mountain House MBR WRF, the City of Adelanto' s4. 0 MGD nutrient removal WRF, the City of San Clemente' s2. 5 MGD WRF, and the City of Show Low Arizona' s 2. 5 MGD WWTP, among others. Maintaining existing operations and transitioning to new facility operations requires special considerations to ensure the plant remains in compliance and the old and new systems function together properly.

and scope of work
PROJECT UNDERSTANDING AND SCOPE OF WORK // 2

DROJECT UNDERSTANDING
Over the last 10 years, the City and land developers have been working together to design and construct the necessary utility infrastructure to support the City' s growth. In 2015, the City, in collaboration with PACE, completed a new 2. 5 MGD Membrane Bio- Reactor (MBR) facility which treats sewage from the new development, producing ultra - high quality Title 22 — 2. recycled water for irrigation. The expansion of this facility began in 2024, with construction currently underway to increase the plant to a combined capacity of 4. 0 MGD of high strength wastewater.

Current sewer flows to the CTF facility average
approximately 1. 7 MGD and high load conditions and
are anticipated to increase significantly over the next few years. Additionally, the City and developers are
anticipating the ultimate buildout capacity of 6. 0 MGD to be necessary sooner than expected due to the rate of development.

The existing CTF facility is currently at a critical stage of expansion, transitioning from the existing Phases 2 and Phase 3, to a final biuldout. Phase 3 was designed with the future Phase 4 expansion in mind.

During the initial technical assessment and development of the Preliminary Design Report ( PDR), our project
team will be working closely with all of the project
stakeholders to identify key aspects of the design that will deliver benefits to both the developers and the
City. Upon completion and agreement on this project
milestone, PACE will proceed to provide engineering
services to develop bid documents consistent with
the objectives and design contained in the PDR.

During preliminary and final design, our project team
will incorporate not only the technical aspects of
engineering the facility" but also continuously review
constructability and operability to ensure that we meet all of the project goals. It is this" Engineering Plus" approach that will be able to deliver on the apparently opposite or contrary objectives of lowering operation
and maintenance costs while simultaneously reducing
project capital cost.

PROJECT APPROACH
PACE will approach this project as a team player and provide the technical and production capacity for implementing the design solutions developed by the project team. Our focus will be on evaluating alternatives for their technical merit and feasibility to deliver sound, dependable operation. As the Engineer -of -Record for the project, we will meet with the City' s Engineering staff and contract operators to evaluate process and equipment alternatives, project schedule and budget. The City and developers have selected to proceed with the expansion of the CTF facility utilizing the MBR process. The PACE team has a substantial amount of experience in the design, construction, operation, and process optimization with both conventional and membrane treatment systems and agrees that the MBR process provides certain project -specific benefits over more conventional design approaches.

FOR SELECTED EQUIPMENT
The use of Performance Specifications for the Headworks equipment selection process allows clients to get competitive bids, evaluate capital and operational costs and operational performance prior to putting pencil to paper.

The major advantage to this approach is that the project team can proceed to design knowing the cost and equipment they will be using in the project without losing the benefit of a competitive free market. Once the equipment has been selected, the design can proceed relatively quickly to produce the 60% preliminary design plan sets.

Based on the Scope of Work proposed for the expansion project, PACE would recommend using this approach to preselect the following major project components:

Influent Screening and Grit Removal for new MBR Separation Process Trains 4 and 5 headworks # 5 and # 6
Main Biological Aeration Grids — Phase 4
In preparation for this proposal, PACE reviewed the Phase 3 design plans for the existing facility. PACE would recommend considering building two more similar sized biological tanks to be used for additional treatment of all wastewater flowing to the facility. Connection mixing pumps, flow -back pipes, and overflow systems will be interconnected between the components of the Phases for mixing of the flows/ lad.

The design approach would also include:

1. Combining headworks discharge with overflow
V -notch weir gates at the upstream end of center
channels.

2. Providing one more headworks expansion
for build - out with similar packaged 316 SS
headworks system.

3. Providing mixing, return, and overflow pipes
between Phase 4 and Phase 2 and 3.

4. Provide air piping to biological basins in Phase 4
from existing Phases.

5. Provide the remaining two (2) MBR trains in
the Phase 2 and Phase 3 buildings including all
required air scour and chemical infrastructure to
these trains.

6. Provide expansion of the existing west chlorine
contact basin for increased disinfection capacity.

7. Providing digester ( Phase 1) tank renovation/
expansion for sludge digestion as needed.

These are just a few opportunities we see for the Lathrop project which demonstrate how our team melds our inhouse, core competencies in Engineering, Construction, and Operations to produce value- added results for our clients.

PACE will re - review flow and load information for applicability to new basis of design. Some modeling has already been performed for this expansion analysis and existing capacity evaluation. PACE will also re - review the CTF flow and load detail for confirmation of peaking load factors. The PACE team has previously evaluated the facility in multiple visits and has extensive background knowledge of the current facility, and in this task will re - verify the assumptions developed in the preliminary concept development already provided to the City as a part of the Phase 3 expansion and provide an updated conceptual design for the full build out expansion. PACE will evaluate the current chlorine disinfection system and design an expansion of the existing west chlorine contact basin and provide estimates for final disinfection capacities for various reasonably anticipated baffling factors. PACE will also study the Equalization tank system and evaluate if and modifications are needed ( design of this, if applicable, is excluded from scope) and compare scenarios for the plants influent holding and ( current and expanded) disinfection capacities. PACE will review with Veolia Operations Staff and City Operators the important facilities and control schemes to be included in the new basis of design to improve its operation. The electrical power system capacity evaluated for Phase 3 will be verified for any new Phase 4 loads and addition of required new electrical hardware determined.

Using the information from the confirmation of basis of design meeting, PACE will provide additional information and details to finalize the overall process design calculations, assumptions, process and instrumentation diagram, and hydraulic profile diagram of the upgraded facility. PACE will finalize major equipment specifications for the proposed plant upgrade. PACE will provide draft electrical engineering design including electrical notes, single line diagram of proposed loads onto existing and proposed service distribution equipment, new electrical load calculations, conduit layout and conduit schedules, and draft electrical details and termination diagrams for new proposed facilities. PACE will provide draft structural engineering design including structural notes, structural calculations, steel and concrete design, and draft structural details of new proposed tanks, buildings, and structures. PACE will provide draft mechanical engineering design including components, piping, minor equipment, instrumentation, and hydraulic structures of new proposed facilities.

RELATED EXPERIENCE
City of Lathrop Advanced Water Treatment and Recycling Facility Expansion — Lathrop, CA As Project Manager, Mr. Komor provided project development, studies, design, and bid and construction administration phase services for the expansion of the Lathrop Consolidated Treatment Facility. This membrane bioreactor ( MBR) wastewater treatment facility features aesthetic architecture. An administration building on - site allows for public outreach and understanding of the facility' s operations for its visitors. The facility' scapacity was expanded from 1. 0 million gallons per day ( MGD) to 2. 5 MGD and then to 4. 0 MGD, with capacity for future build - out to 6. 0 MGD. PACE provided a creative approach to the upgrade with a new secondary and MBR treatment system accessed at grade level. An integrated process mechanical design minimizes valving and pumping, improves process treatment simplicity, and makes the unit processes visible to operators. The design is straightforward and allows the facility to easily expand. Based on a free chlorine contact time revalidation study performed by PACE and approved through the CA Division of Drinking Water ( DDW), the new treatment system process design uses the existing chlorine contact basin ( CCB) so that there is no need to expand the CCB infrastructure for continued production ofTitle 22 disinfected tertiary recycled water under the new design flow conditions. Additionally, PACE designed a conversion for the existing MBR facility that will be used for aerobic sludge digestion and thickening processes.

Mountain House Water Reclamation Facility Expansion — Mountain House, CA Mr. Komor served as the Lead Process Engineer to provide the design, permitting, construction services, and start- up services for the Phase II expansion and is currently providing design for the Phase III expansion of the Mountain House Water Reclamation Facility. The Phase II expansion replaced the 0. 45 MGD aerated lagoon wastewater treatment plant with a 3. 0 MGD advanced SBR Water Reclamation Facility. The Phase III expansion expanded the facility to a build - out capacity of 5. 4 MGD. The secondary treatment process was converted to a membrane bio- reactor to meet the existing waste discharge requirements and also comply with California Title 22 Recycled Water Requirements for unrestricted reuse. As part of the conversion, PACE designed the facility around the use of existing infrastructure. This includes repurposing and subdividing the existing SBR process tanks into anoxic, oxic, and post -anoxic tanks prior to feeding the new MBR facility. The design also incorporates the existing UV channel system for tertiary treatment with the modified and expanded facility.

Adelanto Wastewater Treatment Plant Upgrades — Adelanto, CA Mr. Matthews led the engineering design of new infrastructure and an improvement plan to the existing Parkson BiolacWWTP. Based on the improvements he designed, the plant regained the original capacity, as well as increased the rated capacity to 4. 0 MGD. New plant infrastructure includes new screening and washing systems in the headworks, all new aeration and blower equipment in the existing secondary basins, two new 70' diameter circular clarifiers, a RAS/ WAS pump station, and new internal recycle pumping on the biological process. Modifications were made to the existing effluent filters and chlorine contact basin to produce full Title 22 compliant recycled water.

Improvements were also made to the solids handling to reduce cake volumes and improve dewatering performance.

Show Low Wastewater Treatment Plant Evaluation and Expansion — Show Low, AZ The City of Show Low commissioned PACE to evaluate, design and assist in implementing the most appropriate and cost effective solutions to upgrade and expand the City' sexisting WWTP. The new WWTP utilizes an Extended Aeration Activated Sludge ( EAAS) process to produce effluent quality that can meet AZ Title 18 BADCT effluent limits. Since the construction was completed, the facility has consistently produced effluent with TN level of less than 3 mg/ L (and at times < 1 mg/ L). In addition to the new treatment process, a key component to meeting and maintaining consistent effluent quality is the WWTP process control. Mr. Matthews served as the Principal QA/C and Instrumentation & Controls Lead Engineer to program and integrate the PLC controls and SCADA for the WWTP. Since the WWTP new process requires constant flow and level control in order to maintain proper treatment, a network of PLCs, field instrumentation and SCADA was implemented that allows for tight controls of the process with minimum onsite supervision.

Town of Quartzsite WWTP Evaluation and Expansion — Quartzsite, AZ Mr. Matthews served as the Principal Engineer for the in- depth evaluation of the proposed SBR expansion and the existing SBR system, along with all the other existing unit processes. The evaluation included detailed hydraulic analysis, biological process modeling, energy consumption analysis, and electrical and control system review. PACE' s evaluation identified that the new proposed SBR expansion did not provide adequate summer low flow treatment and would double the electrical power requirements. PACE also identified several capital and operational cost reduction measures that, when combined, provided better day- to- day treatment plant performance, a reduction in capital cost of 20% ($ 750, 00 on $ 4M project) and a corresponding energy cost reduction of 40% equating to a savings of $25, 000/ yr at current flows and up to $40, 000/ yr at design flow. One of the measures included dividing the existing SBR basin into two smaller basins to allow better summer low flow treatment but still had the capacity to treat the design flow of 0. 9 MGD.

Winslow Wastewater Treatment Plant Evaluation and Upgrades — Winslow, AZ PACE performed an evaluation of the deficiencies of the City ofWinslow' sWWTP, which was plagued by operational issues, making the effective treatment capacity roughly half of its design capacity of 2.

Shrimp Farming System Design — Fountain Valley, CA
PACE applied advanced water treatment knowledge and technology to improve aquaculture management and create a sustainable, environmentally friendly technology that raises high quality of Pacific white shrimp ( Litopenaeus vannamei). Water quality is a major concern of any aquaculture facility, so water parameters such as pH, salinity, temperature, total dissolved solids, nitrogen, and dissolved oxygen among others are carefully controlled to ensure shrimp thrive in an environment to maximize growth rate and health. The wastewater generated during the production process is treated and is recycled due within a custom - designed water recirculation system. As the Water Quality Specialist, Dr. Henkanatte Gedara conducted onsite water quality testing and evaluations, P&IDs and chemical evaluation. Without the use of antibiotics or toxic chemicals, this small footprint system is a reliable technology that produces healthy, naturally - grown shrimp.

PACE provided project development, studies, design,
and bid and construction administration services for two phases of expansion of the City of Lathrop Consolidated Treatment Facility ( CTF), an MBR wastewater treatment
facility that treats residential and commercial/ industrial sewage flows. Prior to the first expansion, the facility' s capacity was 1. 0 MGD. The Phase 2 expansion took the
capacity to 2. 5 MGD, and the Phase 3 capacity currently under design will bring the facility to 4. 0 MGD, with
several major provisions designed as part of Phase 3 to support the ultimate buildout capacity of 6. 0 MGD. PACE provided a creative approach to the upgrade with a new
secondary and MBR treatment system accessed at grade
level with an integrated process mechanical design that minimized valving and pumping that improves process
treatment simplicity and makes the unit processes
visible to operators. The design is straightforward and allowed for ease in facility expansion. The new treatment system process design was based around use of the
existing chlorine contact basin ( CCB), without having to expand the CCB infrastructure for continued production
ofTitle 22 disinfected tertiary recycled water under the new design flow conditions. This was achieved through
a free chlorine contact time revalidation study performed by PACE and approved through the CA DDW.

Peak Hourly Flow capacity of 12 MGD. A new biotrain
process, including anoxic, aerobic, and MBR process
tanks and equipping will expand treatment capacity
to 4. 0 MGD. Provisions are being designed for the full buildout capacity of the aeration equipment and include integrating the existing electrical room and aeration
equipment. A new sludge processing and dewatering
system featuring a screw press, sludge drying beds,
and winter dried sludge storage will be included within a new pre- engineered building. An existing basin is
being modified to accommodate sludge processing
and dewatering and is sized for the facility' s buildout capacity. Electrical power and automation controls are
being upgraded to accommodate the buildout capacity,
as well. Upon completion of the 4. 0 MGD expansion, the addition of biological tanks and aeration equipment will be the only components needed to treat the future final phase of 6. 0 MGD buildout capacity.

upgrade its aerated lagoon WWTP that had a design
treatment capacity of 2. 46 MGD. The existing WWTP
process did not have the capabilities to meet stringent effluent requirements, especially for ammonia. In addition, future, more stringent effluent requirements required
major improvements to the existing WWTP. A previous
engineering report recommended constructing a 1. 75
MGD Biolac- type wastewater treatment facility on the
existing lagoon site to meet the flow projection of 1. 72 MGD required for the next 20 years. PACE was asked
to perform and evaluation using capital construction
cost, operation and maintenance costs, and 20 -year life cycle analyses to confirm the recommendation. Further
consideration of a site issue of shallow groundwater
determined that with the site improvements required to
accommodate the groundwater, the City could design
and construct a two -basin 2. 5 MGD Biolac facility for nearly the same cost as the 1. 75 MGD Biolac. This not
only provides the future capacity but also full process redundancy for the current flow up to 1. 5 MGD. With the Relevant Features
Treats domestic and commercial/ industrial
flows
Value engineering / performance - based
specifications
Final construction cost was within 10% of
engineer' sestimate
Final total cost of expansion less than $4/
gallon
City' s decision, PACE designed a new 2. 5 MGD WWTP
utilizes an Extended Aeration Activated Sludge ( EAAS)
based on the Parkson' s Biolac® process to produce effluent quality that can meet AZ Title 18 BADCT effluent limits for Total Nitrogen ( TN) of < 10 mg/ L.

Since construction completion, the facility has consistently produced effluent with TN level of less than 3 mg/ L (and at times < 1 mg/ L). A key component to meeting and
maintaining consistent effluent quality is the WWTP
process control. PACE' sin- house Instrumentation &
Controls Group was hired by the City to program and
integrate the PLC controls and SCADA for the WWTP. Since the WWTP new process requires constant flow and level
control in order to maintain proper treatment, a network of PLCs, field instrumentation and SCADA was implemented
that allows for tight controls of the process with minimum onsite supervision. PACE' sability to provide both process design and engineering, along with the ability to provide controls integration has made the Show Low WWTP
Upgrades Project a great success for the City and was
completed within budget at less than $ 4 per gallon.

The Town of Quartzsite, AZ was having difficulties
with treating its highly seasonal wastewater flow. In
the winter, the WWTP sees an average - day flow of
approximately 350, 00 gpd but the flow drops to less
than 100, 00 gpd in the summer. With anticipated
growth in the winter months, flow is expected to exceed the WWTP treatment capacity within a couple of years.

To increase the WWTP capacity, the Town moved
forwarded with the design of the WWTP expansion only
to stop short of construction due to funding requirements.

PACE was then contracted by the Town of Quartzsite' s
Engineer ( Atkins) to perform an assessment/ value
engineering review of the proposed expansion design
plans that consisted of increasing the current capacity from 0. 45 MGD to 0. 90 MGD by constructing a new
second sequential batch reactor (SBR) basin as well as
other ancillary systems necessary to increase the capacity.

In- depth evaluation of the proposed
expansion
Hydraulic analysis, biological process
modeling, energy consumption analysis,
and electrical and control system review
Received USDA -RD funding
Determined 20% in capital cost reductions
and 40% energy cost reductions
PACE provided an in- depth evaluation of the proposed
expansion and existing system. The evaluation included
detailed hydraulic analysis, biological process modeling, energy consumption analysis, and electrical and control system review. PACE' s evaluation revealed the proposed expansion did not provide adequate summer low flow
treatment and would double the electrical power
requirements. PACE also identified several cost reduction measures that provided better day- to- day treatment
performance, an energy cost reduction of 40% equating
to a savings of $25, 000/ yr at current flows and up to 40, 000/ yr at design flow. One of the solution included dividing the existing SBR basin into two smaller basins to allow better summer low flow treatment but still had the capacity to treat the design flow of 0. 9 MGD. This project was funded through WIFA and the USDA - RD. PACE was
consistently working with the Town and USDA -RD for the successful completion of the project.

Winslow Wastewater Treatment Plant Evaluation and Upgrade Winslow, AZ PACE was hired by the City of Winslow to perform
an evaluation of the deficiencies of the City' sWWTP,
which was struggling to meet water quality permit
requirements. The plant was plagued by operational
issues, making the effective treatment capacity roughly half of its design capacity of 2. MGD. Through the
preparation of a Process, Efficiency, and Alternative
Analysis Evaluation, several major process deficiencies were identified, as well as proposed improvements
for each that preserved as much of the existing facility that was practical. Renovations were recommended to
numerous processes including the lift station, headworks, flow equalization basin, oxidation ditches, filters, UV Firm' s Role
