1 Introduction
The City of Manteca (City) is soliciting ELECTRONIC REQUEST FOR PROPOSALS (RFPs) from professional consulting firms to prepare the Well 29 TCP Treatment Project (Project). Refer to Table 1 for RFP deadlines.

Firms submitting proposals for this project must have a project manager licensed as a Professional Engineer in the State of California and have experience in the field of water infrastructure design.

The City is seeking proposals for the design of the 1,2,3-Trichloropropane (TCP) treatment system for Well

29. Well 29 is located in a residential area at Yosemite Village Park. Vessels will need to be configured to minimize visual impacts at Yosemite Park and surrounding residents.

The City received Compliance Order No. 01-10-21R-002 in April 2021 to provide TCP treatment for Well 29 by April 2024.

Proposals shall be concise, well organized, and demonstrate the consultant’s qualifications and experience relating to the proposed project. At a minimum, proposals shall include the information in the following sections.

Innovation is encouraged to provide the City with comprehensive services in the most efficient, cost effective manner.

2 Background
Well 29 is located at 614 El Portal Avenue in Manteca, California (Figure 1) on the west side of Yosemite Village Park. Well 29 was drilled in 2017. The construction of onsite improvements (well house, paving, fencing, etc.) will be completed in June 2019. Well 29 has an arsenic concentration of 24 micrograms per Liter (ug/L), the maximum contaminant level (MCL) for arsenic is 10 ug/L.

The site contains a well house, emergency diesel generator, and two arsenic filter vessels. The filters will continue to be used to remove arsenic. Well 29 is connected at two locations to the distribution system:
one connection is located west of the well site at El Portal Avenue, and the other connection is located to the east at El Capitan Avenue as shown in Figure 1.

Figure 1: Well 29 Location
Well 29 has a deep well turbine pump that produces 2,000 gpm at 50 psi. During normal operation, a variable frequency drive (VFD) operates the pump as determined by system demand. The VFD is controlled by a programmable logic controller (PLC). The PLC receives a call to run, then signals the VFD to start the pump and run at the flow rate needed to maintain a preset system pressure. The PLC also starts the sodium hypochlorite metering pump at this time and flow paces the sodium hypochlorite metering pump to match the well flow. A portion of the pump discharge flow is diverted into the arsenic filters through the use of a “blending” valve.

RFP ATTACHMENT 2
The amount of water to be treated has been predetermined, based on the arsenic concentration in the source water and the desired arsenic level in the blended effluent (the water leaving the well facility must have an arsenic concentration <8 ppb or ug/L).

A “set point” in the PLC has been established to adjust the blending valve to maintain the proper ratio of treated and untreated water. The treated and untreated waters are brought back together and pass through a static mixer to thoroughly mix the combined waters before entering the distribution system.

The Well 29 PLC has been programmed to monitor and control the well and blending operation.

2.1 Design Considerations
The Well 29 is located within Yosemite Village Park. The site is split into two sections, as shown in Figure 1 to minimize visual impact to local residents. The new TCP treatment vessels shall be located to the east or north of the existing well building. Other site locations recommendations are welcomed and need to be incorporated in proposal.

TCP readings for Well 29 are listed in the following table:

11/09/21 – 15 04/12/21 - 18
10/12/21 – 15
The TCP treatment vessels and associated equipment shall be designed with security and neighborhood aesthetics in mind. The City is interested in evaluating different equipment layouts for energy efficiency, operational flexibility, and maintenance ease. The selected firm will be working with City staff to determine the proper equipment to be installed at the well site.

Full supervisory control and data acquisition (SCADA) will be required via a local control panel at the well site via radio telemetry from the City's Municipal SCADA server located at Well 19. Access control and security system cameras will also be part of the project. The selected engineering firm will be responsible for the design and integration of the local process control system and SCADA system, access control, and security system. Coordination with City staff, and the City's SCADA Consultant, will be required to ensure all design, configuration, and integration is consistent with the City's requirements.

Given the nature of the project location, and its proximity to residents, the selected engineering firm will work with City staff on community outreach activities. These activities will include but not limited to stakeholder meetings, and news releases. The selected engineering firm will provide project slides displaying the project site, selected equipment, and proposed layout.

Subject: Well 29 TCP Treatment Project
Dear Mr. Guillory:

HydroScience Engineers, Inc. (HydroScience) is ideally positioned to design a TCP treatment system for Well 29 that will meet the City’s objectives, achieve the Department of Drinking Water (DDW) compliance date, and provide for reliable and costeffective long-term operations and maintenance (O&M).

We’ve reviewed the key project challenges and requirements, comparing them to our experience designing similar TCP treatment systems at four other City water facility sites as part of the award-winning 2021 TCP Mitigation Project. Our Well 29 project approach will address all key challenges, apply past successes and lessons learned, and take advantage of all the optimizations we collaboratively developed on that prior project to move forward quickly while achieving a high-quality final result.

To meet the schedule objectives, our project approach emphasizes the following:
• Close collaboration with industry contacts to track equipment lead time trends and allow for procurement and installation durations in our master schedule.
• Lock in the overall facility layout early in predesign, so that the CEQA project description can be finalized, and environmental technical studies and documentation development can begin immediately. • Implement an accelerated design process leveraging decisions and details from the 2021 TCP project so that advertisement can begin as soon as possible.
• Maintain outreach to suppliers and contractors to increase interest and improve responsiveness during the bid phase. • Collaborate closely with the City throughout design and rigorously manage the work to stay on track, identify issues early, and resolve them expeditiously.

The HydroScience team we are offering for this project will bring the City the following key benefits:

City Familiarity: We have completed many successful projects for the City of Manteca, including the 2021 TCP Mitigation Project for Wells 23, 24, 27 and the Central Arsenic Treatment Facility, a Water Master Plan and Rate Study, and related work.

We are familiar with City infrastructure, needs, and standards, and are highly motivated to continue to deliver successful projects to the City. Most of our specialty subconsultants worked with us on the 2021 TCP Mitigation Project and bring a similar City familiarity and ability to hit the ground running.

Leadership: Project Manager Bill Slenter lead the highly successful 2021 TCP Mitigation Project to completion, working effectively with the City and the contractor every step of the way. Bill is one of HydroScience’s principals and has the authority to commit resources and make staffing adjustments whenever necessary to keep projects on track. Bill demonstrated his ability to successfully deliver a TCP treatment project with CEQA component for four City sites on time and on budget. Bill also assisted the City in conducting a critical public meeting to allay resident concerns, particularly for the very similar Well 23 site. Bill will utilize similar approaches to deliver a successful outcome for this project at Well 29.

Stability: HydroScience is celebrating its 25-year anniversary. Throughout our firm’s history, we have focused exclusively on planning and design of water-related projects, focusing primarily on public clients in Northern California. This design will be performed out of our local Sacramento office. This includes the electrical and control systems design, which will be performed by our in-house Electrical Department working just down the hall from our civil and mechanical engineers. Our proposed team works together on a daily basis to develop high quality, integrated designs that meet our clients’ long-term operational objectives.

Qualified Team: Project Manager Bill Slenter brings 29 years of water-related experience including TCP treatment design at four City sites. Project Engineer Austin Poulson completed the majority of the civil, process, and mechanical engineering on that project under Bill’s oversight and will reprise this role for Well 29. DDW Compliance Expert Sim Blake brings over 30 years of water design and permitting experience enhanced by a Grade T4 Water Treatment Operator license. Electrical, Instrumentation, and Controls (EIC) lead Thinh Le brings 18 years of experience and he completed EIC design for the 2021 TCP Mitigation Project. We are highly qualified to complete this project for the City.

This proposal is valid for up to 180 calendar days from today’s date. I will be the main point of contact for this proposal and I have the authority to enter into a binding agreement with the City on behalf of HydroScience.

HydroScience appreciates the opportunity to provide service on this project. Should you have any questions about our proposal, please feel free to contact me at (916) 273-6035 or [email protected].

Sincerely yours,

Organizational Credentials, Background
Founded 25 years ago in 1997, HydroScience Engineers, Inc. provides planning, design, permitting, and construction management services exclusively for water, wastewater, and recycled water projects. Our professional staff of 38 includes licensed civil, mechanical, environmental, and electrical and instrumentation engineers as well as funding, permitting, and regulatory specialists; hydraulic modelers; construction managers and inspectors; CAD drafters; and full-time administrative and IT professionals. The work on this project will primarily be done from our Sacramento office, utilizing the same key team members who completed the prior Manteca TCP Mitigation Project in 2021. HydroScience also has offices in Berkeley and San Jose.

Water Treatment Design Experts. HydroScience has extensive experience in planning and designing water treatment and conveyance facilities. We design groundwater treatment plants that treat for iron, manganese, TCP, arsenic, and TDS removal. We design surface water treatment plants with dual-stage pressure filters and ultrafiltration membrane technology. HydroScience is also
experienced in water system master planning,
hydraulic modeling, and feasibility analysis, and we
have provided extensive regulatory compliance
support for both small and large water systems.

We employ licensed water treatment and
distribution operators. This experience allows our
engineers to incorporate an operator’s perspective
into planning and design, measurably improving overall usability and performance.

This expertise is useful in planning for capital projects to ensure new water facilities are appropriately integrated with existing infrastructure to meet current and future needs. This prevents overburdening City personnel and allows for ease and affordability of long-term operations and maintenance.

Experience
HydroScience is well-qualified to provide design services for potable water systems, and has extensive experience in well design and equipping, permitting of well facilities, hydraulic design, pipeline design, and design of wellhead treatment systems including granular activated carbon (GAC) for removal of TCP.

Key staff participation. Every project featured in this section was completed by key members of our proposed team. Our team works together effectively and has developed the knowledge and creative solutions needed to execute TCP treatment at Well 29.

Similar services and design challenges. Our past projects have required a broad range of services and faced similar project challenges to those that will be required by the City. By leveraging this past experience, our team is capable of successfully guiding the project from concept to completion.

Local knowledge and understanding. HydroScience has completed several recent similar projects in this region and we understand local ordinances and project requirements. In particular, this team recently completed TCP treatment designs at four City well sites, as detailed on the next page. One of those sites, Well 23, is expected to be the template for the solutions needed at Well 29. This means we will be able to start work immediately and navigate the challenges of this project without a learning curve, ultimately saving the City time and money.

HydroScience prepared a design report, developed detailed plans and specifications, and provided construction phase engineering support as part of this design/build project to install Granular Activated Carbon (GAC) treatment systems on four existing groundwater well sites in the City of Manteca. The GAC treatment systems remove 1,2,3-trichloropropane (TCP) from groundwater.

HydroScience successfully optimized facility layout and access to minimize neighbor impacts while facilitating long-term O&M. We analyzed impacts on well pump performance, coordinated CEQA, and obtained DDW approvals. We provided a comprehensive landscape design to screen the facility and restore park lands around the work area.

The Well 23 site is particularly relevant, as it is located in a residential neighborhood at the corner of a large City park. A 2,200 gpm GAC treatment system and bolted steel backwash tank was added immediately adjacent to the well building. Due to visual impact concerns, the design placed the GAC treatment vessels on a foundation set about 5 ft below existing grade and surrounded by a concrete retaining wall screened by landscaping and a decorative iron fence. HydroScience prepared two layout options and rendered these in 3D to facilitate informed decision-making, optimization of the layout, and enhanced public outreach and CEQA processes. The CATF site is also relevant in that the new GAC system was integrated with an existing arsenic treatment system, similar to Well 29. The design included a bypass piping manifold to allow operational flexibiltiy.

This project was selected as ENR California’s 2022 Best Project in the Water/Environment category.

Water Treatment and Storage Facility Lytton Rancheria, Sonoma County, California HydroScience planned and developed the design for new groundwater wells, groundwater treatment, treated water storage, and a booster pumping facility to serve the Lytton Rancheria Project, a tribal residential development located near Windsor, CA. HydroScience is design engineer-of-record as part of a design/build project team. The facility will produce an average day flow of approximately 120,000 gallons per day (gpd) at buildout. The design passed a rigorous third party plan check review prior to construction.

New wells will deliver raw water to a water treatment system to reduce concentrations of arsenic and manganese in the groundwater to below maximum contaminant levels (MCLs).

The treatment process will include pH adjustment, oxidation, coagulation/filtration, postfiltration adsorption, and backwash thickening. Dosing of sodium hypochlorite followed by storage in on-site welded steel storage tanks will follow. A booster pump station consisting of banks of low and high flow pumps followed by a hydropneumatic tank will deliver water to the distribution system for residential demands and fire flows. The treatment and pumping equipment will be housed in a new CMU building, which will also contain an operations office, lab, power distribution, and control systems.

The design phase has been completed and construction is nearing completion. Key challenges encountered and addressed included coordinating facility design with the overall layout and grading of the development, incorporating screening and architectural features to maintain aesthetic requirements, developing a phasing approach for construction, and optimizing constructibility and cost in partnership with the contractor.

HydroScience is providing construction phase support including review of RFIs and submittals, field visits, and commissioning support.

Well 13 Rehabilitation and Treatment Elk Grove Water District, California HydroScience provided feasibility, predesign, and design services for the rehabilitation of an inactive water production well and manganese treatment plant. The plant was specifically designed to remove manganese, however, it was subsequently decommissioned after arsenic levels were exceeded subsequent to the lowering of the Federal MCL. Specific services for the project included the following:
• Preparation and oversight of zone sampling and water quality profiling for the well for the purpose of contaminant avoidance and minimization.
• Technical evaluation of an existing 1,000 gpm manganese removal facility and a 35% predesign, and PDR preparation. It was determined that the existing Filtronics process plant could be converted to a conventional manganese greensand system, and retrofit to removing arsenic using coagulation/filtration at minimal cost, should there not be an opportunity for arsenic avoidance.
• Final design for a complete facility retrofit for the entire electrical and SCADA system, mechanical and piping modifications, new control valves and control system, and new chemical storage and feed equipment for the facility.
• The facility was constructed to allow modifications to upgrade the process to include future arsenic removal.
• Phase 2 improvements consisted of adding ferric chloride, sulfuric acid, and sodium bisulfate feeds to remove arsenic by enhanced coagulation. Existing piping runs and injection points incorporated in the Phase 1 project were used to minimize upgrade costs.

Well 29, a 2,000 gpm well with arsenic treatment located in Yosemite Village Park, requires a new wellhead treatment system to remove 1,2,3 -Trichloropropane (TCP) from the water supply. State Water Resources Control Board (SWRCB) Order No. 01_10_21R_002 requires compliance with the
drinking water maximum contaminant level (MCL) standard of 5 parts per trillion (ppt) by April 10, 2024. The well is currently producing TCP concentrations ranging from 14-26 ppt. The selected treatment approach is granular activated carbon (GAC) filters. This TCP treatment approach was
successfully implemented by the HydroScience team at
Wells 23, 24, 27, and at the Central Area Treatment Facility (serving Wells 13, 19, and 21).

The existing well facility was put into operation in 2019.

It has an arsenic treatment system consisting of two
filter pressure vessels (adsorbers) and a bolted steel
backwash tank installed on a concrete slab sunk 3-ft below surrounding grade. A building houses the well and panels.

A central driveway provides access to both facilities. Facility surroundings include the park, residences across the street and to the south, mature trees, turf, and a basketball court.

The key challenges and solutions for Well 29 are
summarized in Table 1 on the following page. Some are
detailed further in the text to follow. Similarities to the 2021 TCP project are noted.

Meeting the DDW compliance deadline of April 10, 2024
will require careful identification and management of critical path items from the outset and efficient execution of the preliminary and final designs. The schedule provided in the next section, Schedule of Work, includes a discussion of key critical path items and how they will be addressed.

HydroScience’s prior work on the 2021 TCP Project will
serve as a jumping-off point for an accelerated preliminary and final design effort, as follows:
• All aspects of that project were carefully coordinated with City engineering, operations, and maintenance
staff. The project results reflect a highly optimized layout and design that meets City needs and is an excellent
template for Well 29.
• The project had a highly successful outcome which was recognized by ENR California’s selection of the project as Best Project in the Water/Environment Category.
• The BODR format, introductory content, and analysis
methodology will be reused.
• Design details and instrument/piping specifications can be reused.
• Our experience completing a very similar project for the City will allow us to make the jump from BODR to 75%
design while staying on the same page with the City.

The procurement of GAC vessels and media is a criticalpath item for the project, with special challenges. The 2021 TCP Project (a design-build project) installed 24 Calgon Carbon Model 12 (12-ft diameter, 8-ft sidewall height) welded steel vessels with cone underdrains, filled with Filtrasorb 400-PH bituminous coal-based carbon meeting AWWA
B604. The City is establishing a long-term carbon supply agreement with Calgon encompassing media change-outs
and reactivation. The Well 29 project is traditional designbid, so procurement cannot start until construction, and this is a long-lead item. The purchased system should maintain a level of commonality with existing systems and the carbon supply equipment.

At the project outset, HydroScience will meet with the
City to review acceptable options for specification of
the vessels and media in the Contract Documents. We
anticipate the City will have preferences for the vessels and media among the options offered (size, configuration, properties, underdrain style, etc.) and will want some level Project Understanding and Approach
The same team members who completed the City’s award-winning 2021 TCP Mitigation Project, led by Project Manager Bill Slenter, will complete this effort for the City. We will apply our knowledge of City standards and priorities and leverage the constructability and O&M optimizations made on the 2021 project to maximize the value of Well 29 improvements and complete design efficiently.

of commonality with the existing TCP treatment systems and compatibility with the pending media supply agreement.

The City will need to determine if sole-sourcing is allowed or desired. Regardless, the specification for treatment vessels and media will be sufficiently detailed to maximize conformance to City requirements and preference.

HydroScience consulted with Calgon regarding lead times and vessel configuration options. Vessel lead times have improved somewhat since 2019/2020. Based on current
production figures, it would typically take 35 weeks from approved submittals to ship the vessels to the site. However, Calgon can work with partner fabricators to reduce this to 20-25 weeks. See Schedule of Work for a discussion of how we will account for procurement lead time in meeting the compliance date.

Calgon advised that typically 3 vessel pairs matching the City’s existing ones would be used for this sized well, providing media life of at least two years at an Empty Bed Contact Time (EBCT) of 10 minutes minimum and a Hydraulic Loading Rate (HLR) between 2-8 gpm/ft2, with the system operating in series mode. However, based on current data it appears that the media life in the City’s existing vessels may be longer than was conservatively predicted. During predesign, HydroScience will collect data on existing TCP treatment operation and review media life predictions versus actual trends. Should the City desire to reduce the project cost and footprint, it may be possible to reduce the Well 29 project to 2 vessel pairs at somewhat increased media changeout frequency and head loss.

The design of the Well 29 TCP system configuration
and layout will closely follow our design of Well 23
improvements, summarized as follows and conceptually
illustrated in Figure 1:
• Install vessels in a 5-ft deep concrete “vessel pit” with access stairs, trench drain and sump, surrounded by
handrail and fencing (see Figure 2).
• Locate system to meet the following objectives:
◦ Optimally screened from residents
◦ Minimize impacts to park
◦ Minimize large tree removal
◦ Provide staff and pneumatic trailer access
◦ Optimize yard piping
• Configure pit with air-gapped sump to convey rainwater to the storm drain while preventing potential for backflow into the pit.

We have reviewed the Well 29 as-builts provided by the City.

We believe that all piping connections required for addition of TCP treatment can be made within the well and treatment site and in El Portal Avenue. Therefore, in the interest of cost and schedule efficiency, our scope does not include survey, geotechnical, or design within the eastern half of the park or El Capitan Avenue. This can be added if necessary as a separate scope.

Our team includes O’Dell Engineering to provide both
surveying and landscape design services on this project. On the 2021 TCP Project, O’Dell worked in close coordination with City Parks Department to develop a landscaping
approach that provided trees, shrubs, and groundcover
matching existing city landscaping, met Parks preferences, and enhanced the visual character of the site perimeter.

O’Dell also designed modifications to existing parks
irrigation systems that would be affected by construction and included new controllers to separate systems where
required. O’Dell knows the City well and will bring their experience with the 2021 TCP Project to bear in moving
through this process efficiently.

Project Manager Bill Slenter will provide public outreach support similar to his work on the 2021 TCP Project, as follows:
• Provide 3D renderings of facility layout options
• Prepare PowerPoint slides for a public presentation of the project
• Assist the City with answering public questions
• Assist the City with preparing a mailer for public
stakeholders
HydroScience will assist the City in preparing amendment language to the existing water supply permit to address the addition of GAC wellhead treatment, as well as an update to the City’s existing operations plan. We will leverage the templates from the 2021 TCP Project to streamline this effort.

Bill Slenter was successful in delivering a completed design and CEQA effort on the 2021 TCP Project and supporting
construction such that the project was completed on budget and on schedule, meeting the City’s DDW compliance
deadline, while incorporating all of the City’s design and O&M objectives. He will utilize the same diligent project management approach on this project, emphasizing a
structured project effort, bi-weekly updates to the detailed master project schedule, close coordination across
disciplines, a highly transparent and collaborative process with City staff, and rapid issue identification and resolution.

Our design approach will emphasize quality management
and verification resulting in accurate bids and minimized construction change orders or delays.

HydroScience will complete the project in accordance with the City’s scope of work (Section 5 of the RFP), as detailed in Table 2 (next page).

Figure 2: Example Vessel Pit Design (Well 23)
This slide from the 2021 TCP Project public presentation demonstrates how HydroScience’s 3D rendering can help convey to the public how the completed facility will look and the efforts made to minimize visual impact.

ECORP will provide the City with necessary filing fees including the County Clerk and CDFW. City would pay necessary fees.

Assumptions:
• The scope assumes that the Project boundary will be provided in georeferenced AutoCAD format or as a .kmz Google Earth file to ECORP at the start of preparation, and that no changes to the original Project boundary or land use components occur. • This scope includes one round of revisions to the draft documents following Client review.
• Archaeological test programs are not included in the scope of work. Should these services be required, they will be separately negotiated. • City to pay all necessary fees
• Included design phase meetings are: 9 bi-weekly meetings, 1 kickoff, and 2 design workshops.
• Scope assumes no special structural foundations will be required based on geotechnical findings. This is defined as a deep foundation such as a pile-supported foundation. The scope does cover either a slab-on-grade or a grade-beam foundation. Based on review of existing geotechnical information provided, one of these outcomes is most probable. • Geotechnical scope includes review of the existing geotechnical report provided by the City. Locations of new borings will be coordinated with the City prior to mobilization, and will differ from the existing boring locations.

Manteca Well 29 TCP Project
Design Schedule
11/10/2022
Schedule of Work
Objections to Professional Services Agreement
HydroScience has no objections to terms contained in the City’s Agreement for Professional Services and meets all insurance requirements.

Key Schedule Features
Schedule for design and bidding is driven by vessel procurement, fabrication, and installation as well as CEQA clearance, as shown.
• CEQA project description and a 10% facility layout will be locked in by first week of February 2023 to facilitate CEQA completion prior to awarding the construction contract.
• HydroScience to implement an accelerated design to meet the schedule, leveraging our completed work from the Well 23 project as a template. • City review periods are 2 weeks for most submittals, but must be 1 week for CEQA items as shown. Design will progress during City reviews to meet the schedule. • Project Manager Bill Slenter to closely collaborate with City project manager to keep to this schedule and provide regular schedule updates, same as our successful approach on the 2021 TCP projects.
