I DEBT SERVICE & CAPITAL PROJECTS
Long-Term Debt
This section discloses the City's outstanding long-term debt, the legal debt limit applicable to General Law cities in California, principal and interest requirements to maturity by activity, and the effect of debt service on City operations. Outstanding balances and debt service requirements are sourced from Note 8 (Long-Term Liabilities) to the City's audited FY 2024-25 Annual Comprehensive Financial Report (ACFR).
Legal Debt Limit
As a General Law city, the City of Coachella's authority to issue general obligation bonded debt is limited under California Government Code Section 43605 to 15% of the assessed value of all real and personal property within the City, as shown on the last equalized assessment roll. The City has no general obligation bonded debt outstanding and none is planned for FY 2026-27. All debt shown in this section is either payable from a specific pledged revenue source (enterprise revenue bonds, State Revolving Fund and USDA loans secured by utility rates), a lease obligation, or a pension obligation bond payable from general City resources; none of it constitutes general obligation bonded debt subject to the Section 43605 limit. The City therefore retains its full legal debt margin.
Per the City's ACFR statistical section (Legal Debt Margin Information), FY 2024-25 net assessed valuation of $3,103,367,022 converts to an adjusted assessed valuation of $775,841,756 under the 25%-of-market-value basis in effect when the Section 43605 limit was enacted, yielding a legal debt limit of $116,376,263. With no general obligation bonds outstanding, the City's full $116,376,263 legal debt margin remains available — 0.0% utilized.

The City has carried no general obligation bonded debt in any of the last five years shown.

Citywide Debt Service Requirements by Year
Item 7.
City of Coachella | Adopted Annual Budget | Fiscal Year 2026-27 53990 Enterprise Way, Coachella, CA 92236 | (760) 398-3502 Page 114 Non-City Obligation Debt (Fiduciary — Not a City Liability) The Successor Agency to the former Redevelopment Agency (reported as a fiduciary Private-Purpose Trust Fund, not part of the City's own governmental or enterprise debt above) had $23,879,969 in outstanding Tax Allocation Bonds at June 30, 2025 (2013, 2014, 2016A, and 2016B Series), payable solely from pledged Redevelopment Property Tax Trust Fund (RPTTF) revenues through final maturity in FY 2036-37. This debt is not a City obligation and is excluded from the legal debt limit and from all fund balance and net position totals presented elsewhere in this document.
Separately, Community Facilities District No. 2018-1 (Glenroy) had $5,230,000 in outstanding Special Tax Bonds, Series 2018 at June 30, 2025, secured solely by special taxes levied on parcels within that district under the Mello-Roos Community Facilities Act. This debt is non-recourse to the City's general credit and is also excluded from the Section 43605 limit and from the City's own debt totals.
Per Note 8 to the ACFR, the 2013 and 2014 Tax Allocation Bond Series retire earlier, in FY 2027-28 and FY 2029-30 respectively, while the 2016A and 2016B Series carry the RPTTF obligation through final maturity in FY 2036-37, which is the year cited elsewhere in this document as when the structural deficit outlook improves.
Effect of Debt on Operations
Governmental-activity debt service is funded from several sources: General Fund transfers to the Debt Service Fund (covering the Pension Obligation Bonds and the 2016 Lease Revenue Bonds); a dedicated State Gas Tax transfer (covering the Gas Tax Revenue Refunding Bonds); Development Impact Fee revenue (covering the real property loan); prior-year Bridge & Grade Separation fund reserves (covering the 2023 Energy Improvement Financing Agreement's governmental share); and departmental operating budgets citywide (covering vehicle, copier, and building leases). The Pension Obligation Bonds were issued in December 2020 to prefund a portion of the City's unfunded CalPERS liability at a lower fixed borrowing cost than the plan's assumed discount rate; the resulting annual General Fund-supported debt service is a fixed, non-discretionary cost through FY 2035-36 and is factored into the General Fund's structural deficit discussion elsewhere in this document.
Enterprise fund debt service is paid entirely from Water Authority and Sanitary District utility rate revenues and does not draw on the General Fund. The Sanitary District's SWRCB and USDA loans account for the largest near-term enterprise principal payments (FY 2026-27 alone: $1,536,413), consistent with those loans' original amortization schedules; both are more than half repaid and continue to amortize through FY 2051-52. The revenue bonds of both utilities carry rate covenants requiring net utility revenue to cover debt service by a minimum of 1.25 times, per the respective bond resolutions. For FY 2024-25 (per the City's ACFR statistical section, Revenue Bond Coverage schedules), the Sanitary District's net revenue available for debt service of $4,828,745 covered total debt service of $2,321,057 by 2.08 times, and the Water Authority's net revenue available for debt service of $2,523,323 covered total debt service of $1,169,622 by 2.16 times — both comfortably above the 1.25 times covenant and consistent with coverage in each of the last ten fiscal years.
Credit Ratings
Per the City's Municipal Advisor (debt profile dated August 2026), the table below shows underlying long-term ratings for each rated issue, expressed as Moody's / S&P Global Ratings / Fitch (a dash indicates that agency does not rate the issue). Outstanding par amounts reflect the Municipal Advisor's August 2026 snapshot and are provided for current reference; they may differ from the June 30, 2025 audited balances presented elsewhere in this section due to the different measurement dates and scheduled principal payments made between those dates.

2005 SWRCB Loan $2,890,351 --/--/-- (not rated)
2005 USDA Loan $3,577,438 --/--/-- (not rated)
The Pension Obligation Bonds and Gas Tax Revenue Refunding Bonds carry the City's strongest ratings (AAfrom S&P), reflecting their General Fund security and the essential, stable nature of gas tax revenues. The 2016 Lease Revenue Bonds and the Water Authority's revenue bonds are rated A+ by S&P. The Sanitary District's 2015 Wastewater Revenue Refunding Bonds carry the City's lowest rated issue, at BBB- from S&P. The 2023 Energy Improvement Financing and the Sanitary District's USDA and SWRCB loans are direct bank or state/federal agency placements and do not carry published ratings, consistent with standard practice for financings of this type and size.
For reference, the former Redevelopment Agency's Successor Agency Tax Allocation Bonds — a fiduciary, non-City obligation discussed under Non-City Obligation Debt below — carry ratings of A from S&P (all four series), with the 2013 Series additionally rated A1 by Moody's. Community Facilities District No. 2018-1 (Glenroy) Special Tax Bonds are not rated.

GENERAL FUND GRAND TOTAL 63.53 55.40 77.43
The FY 2026-27 position-level build above totals approximately 0.2 FTE below the confirmed General Fund total of 77.6291 FTE reported elsewhere in this budget document (Section E and the Authorized Positions summary). The confirmed 77.6291 FTE figure, drawn directly from the Labor Distribution worksheet's total row, remains the controlling figure; the minor variance reflects rounding in a small number of shared/split administrative positions at the sub-FTE level.

Community Profile & Statistical Section
This section presents demographic, economic, and operational context for the City of Coachella, drawn from the Statistical Section of the City's Annual Comprehensive Financial Report (ACFR) unless otherwise noted. Data in this section is unaudited.
About the City
The City of Coachella traces its founding to 1898, when town founder Jason L. Rector established a mesquitewood rail terminal (originally named “Woodspur”) on a Southern Pacific Railroad siding. After the Rector brothers successfully drilled a 550-foot artesian well in 1900 to prove the valley’s irrigation potential, developers laid out the townsite in January 1901; a printer’s misreading of the intended name “Conchilla” produced “Coachella,” which was adopted for both the town and the surrounding valley. The City incorporated on December 13, 1946 by a 5-1 vote under the general laws of the State of California, growing from an original 2.5 square miles to its present incorporated area of approximately 32 square miles.
Coachella is located at the east end of the Coachella Valley, approximately 40 miles south of Palm Springs, California, surrounded by agricultural land to the south, undeveloped land to the east and north, and urban growth to the west. The broader Coachella/Thermal/Mecca area includes more than 70,000 acres irrigated by the Colorado River via the Coachella Canal system, supporting some of California’s largest lemon, avocado, fig, and persimmon crops. Known as the “City of Eternal Sunshine — Gateway to the Salton Sea,” Coachella has a predominantly young, family-oriented population with deep Hispanic cultural heritage.
The City operates under a council-manager form of government, with four Council Members elected at large to staggered four-year terms, a directly elected Mayor serving a two-year term, and a Mayor Pro Tem selected by the Council on a rotating annual basis. The City Manager is appointed by and reports to the City Council. As a full-service city, Coachella directly provides or contracts for the following services:
● Police and fire protection (contracted with Riverside County) ● Highways, engineering, building, streets, and park maintenance ● Planning and zoning
● Public improvements (Capital Improvement Program)
● General administrative services
● Water and sewer utility services
● Code enforcement and animal control
● Economic development

Capital Improvement Plan — Five-Year Summary (FY 2026-27 – FY 2030-31)
The table below summarizes the City's Capital Improvement Plan (CIP) covering FY 2026-27 through FY 2030-31 and beyond, sourced from the FY 2026-27 Capital Improvement Plan Budget document. Full project detail sheets — including project description, status, funding plan by source, project photos, and a chart of each project's funding sources and expenditure categories — are provided in the standalone FY 2026-27 Capital Improvement Plan Budget document referenced in this budget's Table of Contents. Categories include Facilities (F), Landscape & Lighting (LL), Parks (P), Sanitary/Wastewater (S, SD), Streets (ST), and Water (W).
Definition of Capital Expenditures. For purposes of this Capital Improvement Plan, a capital expenditure is an expenditure of $5,000 or more for the acquisition, construction, or improvement of a capital asset -- land, buildings, infrastructure, or equipment -- with a useful life exceeding one year, consistent with the capitalization threshold applied to minor equipment purchases throughout the division-level budget schedules in this document (e.g., items coded “Minor Equipment, Furniture, <$5,000” are expensed rather than capitalized). Recurring maintenance and repair activity that does not extend an asset’s useful life is budgeted as an operating expenditure within the applicable department’s Professional & Contract Services or Supplies & Materials categories rather than in the Capital Improvement Plan.

STAFF REPORT
8/26/2026
TO: Honorable Mayor and City Council Members
FROM: Andrew Simmons, P.E., Public Works Director/City Engineer PREPARED BY: Brianna Greenwood, P.E., Senior Civil Engineer SUBJECT: Reimbursement Agreement for Preliminary Engineering Services with the Union Pacific Railroad Company for the Connect Coachella Project, City Project ST-138.
STAFF RECOMMENDATION:
Authorize City Manager to execute a reimbursement agreement for Preliminary Engineering Services with the Union Pacific Railroad Company in the amount of $40,000 for the Connect Coachella Project, City Project ST-138.
FISCAL IMPACT:
No fiscal impact. This project has been included in the FY 26/27 CIP budget.
BACKGROUND:
The City of Coachella was awarded State funding for Design and Right-of-Way Services for the Active Transportation Program (ATP) Connecting Coachella Project ST-138. The total funds are in the amount of $2,529,412.00, with an amount of $2,150,000 in grant funding and $379,412.00 in local match. The project has completed the PA&ED phase and is currently in the R/W and PS&E phase.
The proposed project will add 3.6 miles of a Class I multi-modal path along Grapefruit Blvd from Avenue 48 to Avenue 54, 2.6 miles of Class II bike lanes along Avenue 54 from Van Buren to City limits, 1.4 miles of sidewalk, and 14 crosswalk enhancements. The project will connect to the Coachella Valley Link Multi-Use Trail (CV Link) and the Arts and Music Line Connect Multimodal Pathway. Infrastructure improvements also include a roundabout; lighted bollards; 6 to 12-foot landscape buffer with shade trees; high-visibility crosswalks; enhanced signals; and raised medians and ADA ramps to improve pedestrian/bicycle safety at crossings. New shade structures, benches, drinking fountains, bike repair kiosks, trash cans, and art installation will enhance the path as well.
Item 8.
DISCUSSION/ANALYSIS:
The project is proposing a pedestrian/bicycle crossing along Avenue 54 over the railroad to connect to the CV Link. This would require work to be done by the Union Pacific Railroad (UPRR) to the existing at grade crossing. The City Engineering team is working with the Union Pacific Railroad Company to ensure the proposed improvements are per their design requirements. The proposed reimbursement agreement would include review of construction documents, project design, preparation of project estimate and construction agreement. Staff recommends approving the reimbursement agreement to continue to work with UPRR and prevent any delays.
CONCLUSION:
Authorize City Manager to execute a reimbursement agreement for Preliminary Engineering Services with the Union Pacific Railroad Company in the amount of $40,000 for the Connect Coachella Project, City Project ST-138.

TO: Honorable Mayor and City Council Members
FROM: Castulo Estrada, Utilities Director
PREPARED BY: Castulo Estrada, Utilities Director
SUBJECT: Authorize the City Manager to Execute a Professional Services Agreement with Waterworks Engineers, LLC for Engineering Services for the Design of Hexavalent Chromium Treatment Plants at Seven Well Sites in an amount not to exceed $4,581,756.00 and Approve Additional Expenditures for a Total Request of $4,810,843.80.
STAFF RECOMMENDATION:
Approve and authorize the City Manager to execute a Professional Services Agreement with Waterworks Engineers, LLC for engineering services for the design of Hexavalent Chromium Treatment Plants at Seven Well Sites in an amount not to exceed $4,581,756.00 It is also recommended that the council approve the following expenditures. Contingency (5%) - $229,087.80
The total cost of this request is $4,810,843.80.
FISCAL IMPACT:
The Hexavalent Chromium Treatment Plants at Seven Well Sites Project, City Project W-55 is a multi-year project and is estimated at approximately $55 million, which includes design and construction. Staff anticipated design services would be approximately $5 million and the Project is included in the 2026-27 Capital Improvement Budget in the amount of $3 million. The remaining $2 million was programmed in FY 2027-28 budget per the five-year CIP. Staff is requesting the $2 million programmed for FY 2027-28 be moved to the 2026-27 Capital Improvement Budget.
BACKGROUND:
On August 1, 2023, the State Water Resources Control Board (State Water Board) released a proposed hexavalent chromium (Cr-6) regulation proposing a 10 ug/L maximum contaminant level (MCL) for drinking water. The State Water Board adopted the MCL for CR-6 on April 17, 2024.
Item 11.
The compliance period after the regulation came into effect on October 1, 2024 is two years for water systems with >10,000 service connections and three years for water systems with 1,000 to <10,000 service connections. The City of Coachella through its Water Authority operates a public water system (PWS) that is impacted by the Cr-6 regulation. Under the regulation, our compliance period would be three years, we have approximately 9200 connections.
The Cr-6 regulation identifies three treatment technologies as Best Available Technologies (BATs): ion exchange, reduction/coagulation/filtration (RCF), and reverse osmosis; but it also recognizes that there are conditions in which other means of compliance may be available, including the use of stannous chloride (SnCl2) to reduce Cr-6 to Cr-3 without filtration. In its Initial Statement of Reasons for the Hexavalent Chromium Maximum Contaminant Level (MCL) Regulation, State Water Board acknowledged that there may be conditions under which SnCl2 could be a viable technology for decreasing Cr-6, and a PWS can use SnCl2 under the correct conditions. However, State Water Board determined that for SnCl2 to be considered a BAT, additional information on the capability of the technology to meet the proposed MCL would be necessary, including information on re-oxidation in the distribution system and the ability to meet a potential MCL without exceeding the tin (Sn) NSF 60 maximum use level (MUL) of 0.063 mg/L, as well as the fate of all forms of chromium (Cr) when SnCl2 is used. The State Water Board intends to request additional evaluation of the distribution system water quality should this technology be proposed for use by a PWS.
Accordingly, the City pursued parallel compliance strategies consisting of: (1) continued evaluation of SnCl₂ as a potential treatment technology for reducing Cr(VI) to Cr(III) without filtration; and (2) evaluation and advancement of conventional treatment alternatives, including RCF, to provide a reliable path toward regulatory compliance.
Based on the City's pilot testing, compliance plan, and evaluation of available treatment technologies, RCF has been identified as the preferred treatment approach for implementation at the City's seven affected well sites. The proposed improvements generally include replacement or modification of well pumps, construction of new RCF treatment facilities, filter backwash residuals management, and associated electrical, instrumentation, and control systems necessary for reliable and effective operation of the treatment facilities.
DISCUSSION/ANALYSIS:
On May 28, 2026, the City issued and posted a Request for Proposals (RFP) for professional services associated with the design and implementation of Cr(VI) treatment improvements at the City's seven well sites. The proposal submission deadline was July 14, 2026. While the list of “plan holders”, who downloaded a copy of the RFP included 12 firms, contractors, vendors, etc., as seen on Attachment #3. The City received only one proposal from Waterworks Engineers, LLC in response to the RFP. Following the City's procurement process and evaluation of the submitted proposal, Waterworks Engineers, LLC was determined to be the lowest responsible proposer and is recommended for award of a Professional Services Agreement in an amount not to exceed $4,581,756.00.
Item 11.
City staff believes the Water Works Engineers/Corona Environmental Consulting Team (WWE/Corona Team) is the best suited engineering team for the Project. The WWE/Corona Team has been at the forefront of addressing emerging groundwater quality challenges in California for more than two decades, providing planning, pilot evaluation, and treatment design services for utilities impacted by hexavalent chromium (Cr(VI)). The team has supported agencies and water providers throughout the region, including projects in Coachella, Desert Hot Springs, Indio, and other groundwater-dependent communities, evaluating and implementing technologies such as reduction/coagulation/filtration (RCF), strong-base anion exchange, and other advanced treatment solutions to meet evolving regulatory requirements. Drawing on extensive experience with groundwater treatment facilities and contaminant removal programs, the WWE/Corona Team brings a deep understanding of Cr(VI) compliance strategies, life-cycle costs, residuals management, and operational considerations, helping Southern California agencies deliver safe, reliable drinking water to their customers.
The WWE/Corona Team completed the preliminary design for Cr(VI) for the seven well sites and will maintain project design momentum to develop well thought-out detailed designs for each well site. Since performing pilot testing and submitting the preliminary design report to CWA, WWE and Corona continue to gain additional knowledge and experience centered around Cr(VI) treatment state-wide and within the Coachella Valley, including Cr(VI) removal technology evaluations, compliance planning, preliminary and final design services, DDW permitting, and DWSRF funding support for over 8 clients (4 of which are in the Coachella Valley) at over 25 well sites in California alone. The WWE/Corona Team will leverage similar design elements from their most recent 2,000-gpm Cr(VI) design project in Dixon, CA (90% design completion on 9/1/26) for the CWA Seven Wells Project, conserving engineering effort, project budget, and time to the benefit of CWA and their customers.
City staff is actively seeking external funding for the Project from federal and state sources. In July of 2023 with the help of Assembly-member Eduardo Garcia and State Senator Steve Padilla the City secured $500,000 through an appropriation in the 2023-24 state budget.
Recently, the City received $746,868.00 through a Community Project Funding request made by the office of Congressman Raul Ruiz.
City staff is currently working with the State Water Resources Control Board staff on a Drinking Water State Revolving Fund application for funding support.

Project Background and Objectives
Coachella Water Authority (CWA) provides drinking water to the City of Coachella through 9,200 service connections. All seven of the existing/newly developed groundwater source wells have hexavalent chromium (Cr(VI)) concentrations above the newly adopted California State Cr(VI) maximum contaminant level of 10-µg/L and require treatment by of August 2031. Reduction coagulation filtration (RCF) has been identified through extensive Cr(VI) removal technology evaluation and Compliance Plan as the preferred treatment technology for Cr(VI) treatment at each of the approximately 2,000-gpm well sites. The treatment facilities required at each of the 7 well sites (Project) generally include: well pump replacement, new RCF Treatment Facilities (pressure contactors and filters; ferrous chem. feed), filter backwash residuals management, and the associated electrical, instrumentation, and controls for effective operation. A preliminary 3-D rendering of the initially planned Well 19 Site is provided below.
Unparalleled Project
Understanding and Support
Our Team understands the City’s
predicament – 100% of the City’s
groundwater wells require Cr(VI)
treatment quickly and the City’s
associated financial burden to perform
the required improvements is
substantial. WWE will join CWA in their
pursuit of federal and state grants and
loans (DWSRF) for the Project providing
the following approaches to facilitate
Project funding:
✓ WWE’s experience with DWSRF
applications and our approach to modify the Basis of Design Report to serve as the “Engineering Report” required in the application will facilitate the City’s ability receive planning and engineering design costs reimbursement for the Project.
✓ In order to meet the 90% Design Submittal deadline by the end of the year, WWE has taken considerable effort to develop the design delivery approach and team that is committed to meeting a 90% Design Submittal delivery date to CWA of December 18, 2026 and a Final Design Submittal date of 9/1/2027.
Maintain Project Momentum
Our Team (WWE and Corona Environmental Consultants) will build upon the knowledge gained during the preliminary design to develop well thought-out detailed designs for each well site. Since performing pilot testing and submitting the preliminary design report, WWE and Corona continue to gain additional knowledge and experience centered around Cr(VI) treatment state-wide and within the Coachella Valley, including Cr(VI) removal technology evaluations, compliance planning, preliminary and final design services for over 8 clients (4 of which are in the Coachella Valley) at over 25 well sites in California alone. Our team will leverage similar design elements from our most recent 2,000-gpm Cr(VI) design project in Dixon, CA for the CWA Seven Wells Project, conserving engineering effort and time to the benefit of CWA and their customers.

Project Background
Coachella Water Authority (CWA) provides drinking water to the City of Coachella (City) through 9,200 service connections. All six of the existing groundwater source wells have hexavalent chromium (Cr(VI)) observed above the California State Water Resources Control Board Department of Drinking Water (DDW) newly adopted Cr(VI) maximum contaminant level of 10-µg/L and require treatment. It is anticipated that a seventh well, newly developed Well 20, will also need Cr(VI) treatment. This leaves the City with no potable water sources that will meet the new drinking water regulation without treatment. Reduction coagulation filtration (RCF) has been identified through extensive Cr(VI) removal technology evaluation and Compliance Plan as the preferred treatment technology for Cr(VI) treatment at each of the approximately 2,000-gpm well sites. The treatment facilities required at each of the 7 well sites generally include the following:
• New Well Pump – Implemented to maximize hydraulic well and treatment capacities • Reduction Coagulation Filtration (RCF) System (2,000- to 2,200-gpm) o Chemical Storage (incl. chem. shed; <120-ft2) and Injection System Mods (Ferrous Chloride) o Reduction Contactor(s)
o Chemical Storage and Injection System Modifications (12.5% SHC) o Filtration Vessel(s)
• Residuals Management System
o Solids Management System
▪ 2% Solids Metering to Sewer (Wells 11, 18)
▪ Backwash Equalization Tank and 2% Solids Metering to Sewer (Wells 12, 16, 17, 20) o Backwash Reclaim System (Well 19)
▪ Backwash Reclaim Tank
▪ Backwash Reclaim Pump (80- to 160-gpm)
• Electrical, Instrumentation, and Controls associated with new facilities • Yard Piping associated with new facilities

Due to the City’s foresight and desire to minimize the financial impact of the new drinking water requirements on their residents (severely disadvantaged community), CWA is actively seeking external funding for the Project from federal and state sources.
Project Success
Immediate project success is define as:
✓ Delivery of the 90% Design Deliverables to CWA for submission by CWA to SWRCB by January 31, 2026 to support the ongoing funding efforts.
The overall project success is defined as:
✓ Successful design, construction, and implementation of the most cost-effective and reliable Cr(VI) removal process, RCF, at each of the project sites
✓ Provide a safe continuous supply of potable water to the City of Coachella residents complying with the new Cr(VI) MCL of 10-µg/L by the anticipated compliance deadline of August 2031 (per Revised Compliance Plan and SB 466, accepted October 3, 2025)
Project Objectives
The overall objective of the Project is to treat raw water to below the finished water quality goals. The finished water quality goals based on full flow treatment is hexavalent chromium and total chromium below or equal to 8-µg/L and total iron (introduced with RCF treatment using ferrous iron) below or equal to 0.1-mg/L. Based on pilot testing performed by our Team during preliminary design, the treatment system will be designed based on the following design criteria:

Project Funding Acquisition is Paramount - 90% Design by Dec.18, 2026 Water Works Engineers project methodology is crafted around the primary project objectives to provide Cr(VI) compliant water to the City quickly and cost-effectively. The compliance deadline is quickly approaching, and significant funding is required to complete the design and construction of the Project improvements.
In order to meet the 90% Design deadline by the end of the year, WWE has taken considerable effort to develop the design delivery approach and team that is committed to meeting a 90% Design Submittal delivery date to CWA of December 18, 2026.
Water Works Engineers is poised to assist CWA in securing project funding through the SWRCB, DFA – DWSRF Program. Water Works Engineers is currently involved with DWSRF design and construction funding assistance with the California Water Service on 4 PFAS removal projects, with the Washington Water Service on 6 PFAS removal projects, and for New Mexico Water Service on 2 PFAS removal projects. We are well practiced and knowledgeable in assisting our clients through the process and will leverage this experience on the CWA Cr(VI) Project.
WWE will assist CWA in developing the required engineering support documentation required to apply for planning and engineering design costs reimbursement for the Project. WWE will facilitate this valuable funding mechanism, joining with the City to save their customers significant money, through early communication with DFA and submission of various application packages. WWE will provide direction and support to CWA in obtaining planning and design cost reimbursement from the feds/state, including the adaptation of the BODR for the Project to serve as an “Engineer Report” (as required in the Technical Application Package).
Maintain Project Momentum
The Project Team will build upon the knowledge gained during preliminary design to develop well thought-out detailed designs for each well site. Since performing pilot testing and submitting the preliminary design report, WWE and Corona continue to gain additional knowledge and experience centered around Cr(VI)treatment state-wide and within the Coachella Valley. WWE/Corona offer continued insight and unbiased direction on and into long-term operation and insight on continued Cr(VI) removal development utilizing RCF and developing landscape for RCF Treat To Waste (TTW) and solids management approaches.
Thinking Ahead
As identified in the PDR, the Project Team will work to address additional design considerations as we head quickly into final design, including:
• Verify planned well flowrates and utilizations with CWA • Provide input/coordination and review the Well 20 well site design, including:
o Design, drill, and installing new well pump
o Well capacity testing and reporting
o Groundwater quality testing to confirm applicable treatment selection and sizing • Assist with land procurement for Well 16
• Perform site surveys for each well site
• Prepare site-specific geotechnical reports for each well site

Hit the Ground Running!
WWE has spent significant timing developing the CPM Project Schedule (See Appendix C – Proposed Schedule) during the preparation of this proposal. Through this detailed scheduling approach, intended to inform our project approach and staffing, we are taking the following delivery approach steps:
• Hit the ground running – Minimize startup and Project kickoff time • “Right Timed” Tasks – Decouple long-lead time tasks (survey, geotechnical, and potholing tasks) from key 2026 design deliverables as appropriate – Provides additional effective 60% & 90% design time for the engineering team without sacrificing design quality. • Provide a design and review respite after 90% delivery to provide CWA with additional time after the Winter Holidays for detailed review, operations equipment preference selection, etc. without affecting the overall project compliance deadline
Practiced Focused Team:
WWE has assembled a focused design team for the Project that is well-practiced in working together on similar projects (Groundwater Treatment, Pressure Filters, Multiple (up to 5-sites) project sites under one project at the same time) over the past 8-years. The same team proposed for this Project, including Corona Environmental Consulting, is currently working on a similar RCF Cr6 -removal project in Dixon, CA (60% and 100% Design delivery date of July 2026 and October 2026, respectively; effectively 3-4 months ahead of the CWA 7 Wells Project). Our team will leverage similar design elements from the Dixon project for the CWA Seven Wells Project, conserving engineering effort and time to the benefit of CWA and their customers.
Technical Competency – Reduction Coagulation Filtration (RCF) Our Team (Water Works Engineers and Corona) brings industry-leading experience in the evaluation, pilot testing, and design of RCF systems. We have repeatedly demonstrated our ability to optimize RCF configurations to reduce capital footprints, manage backwash waste, and maximize treatment for other cocontaminants of concern. • California Water Service (Cal Water), Salinas District – Los Lomas LL-205 RCF Implementation:
Cal Water had a well in their Las Lomas system with
existing an ATEC iron and manganese treatment system
that also required Cr(VI) treatment. Corona conducted
novel first-of-its-kind laboratory bench-scale and on-site pilot testing was conducted to determine if the existing system could be retrofitted and optimized to
simultaneously remove Cr(VI) and manganese. Corona’s
successful pilot testing conducted at this site found that the reduction time, traditionally thought to take upwards of 45 minutes, could be reduced to less than 2 minutes, substantially reducing the cost and footprint of the
process and increasing its applicability to utilities across the e state of California. Additionally, subsequent oxidation of residual ferrous using free chlorine was successful, dramatically simplifying the overall process. These discoveries saved Cal Water rate payers nearly $1M in capital costs and led to the installation of the first full scale RCF treatment unit for Cr(VI) removal at the Los Lomas LL-305 site. Corona developed the basis of design for this project, and the detailed design

Corona also led the start-up, permitting and development of the Operations and Maintenance plan for the treatment system. • City of Watsonville – Hexavalent Chromium Well Treatment Improvements: Partnered to address Cr(VI) levels exceeding 10 µg/L across six municipal production wells, Corona’s comprehensive pilot testing program successfully validated RCF as the optimal technology. By utilizing specialized high-rate, low-density filter media during testing, we proved the system could operate at higher loading rates. This drastically reduced the necessary equipment footprint and decreased instantaneous backwash rates by 75%, effectively eliminating the need for expensive backwash storage tanks and reducing upfront CapEx. Following the regulatory reinstatement of the MCL in 2024, our team re-confirmed RCF as the most cost-effective long-term solution. Corona continues to support the City as a technical advisor through the design phase and will be completing targeted RCF pilot-scale testing this summer to answer key design questions ahead of the 60% design submittal.
• Soquel Creek Water District – Hexavalent Chromium Implementation Study: Engaged to develop a unified compliance strategy for three groundwater wells impacted by the 10 µg/L Cr(VI) maximum contaminant level (MCL). The Corona team managed site-specific water quality analyses, developed 20-year net present worth estimates, and executed bench- and pilot-scale testing to validate fullscale configurations. Testing allowed us to optimize chemical dosing and operational run times, providing continuous treatment process guidance and engineering review through 100% design for a consolidated RCF treatment facility scheduled to be operational in 2027. • California Water Service (Cal Water), Dixon District – Stannous Chloride & RCF Transition Support: Initially retained to study the feasibility of utilizing stannous chloride (SnCl2) without filtration to reduce Cr(VI) at a newly constructed well site. Our advanced pilot-scale simulated distribution testing revealed that SnCl2 caused severe tin and chromium accumulation on pipe surfaces, fouled in-home treatment devices, and generated water quality samples exceeding 50 times the regulated total chromium limit. Based on these critical failure points, we successfully transitioned the utility to an RCF approach. We continue to support Cal Water through the design phase, led by Water Works Engineers, providing test matrix development and technical oversight for upcoming vendor piloting.
• Mission Springs Water District (MSWD) – Preliminary Design of Cr(VI) Treatment Facilities:
Building upon a previously compiled "Hexavalent Chromium Treatment Roadmap", the Corona/Water Works Engineers Team initiated preliminary design configurations for ferrous iron RCF installations across eight wells exhibiting historical Cr(VI) concentrations greater than 8.0 µg/L. This work directly leverages bench/pilot testing alongside the compilation of Class 5 capital and O&M cost estimates to ensure long-term operational resiliency and fiscal predictability for the District’s water system.

• Roadmap Development & Pilot Operations: Formulated a comprehensive Cr(VI) Treatment Roadmap comparing active production needs against state-approved Best Available Technologies (BATs). To resolve complex wastewater discharge constraints, we executed a 14-week RCF pilot study that verified ferrous iron doses, established precise hydraulic loading rates, and demonstrated successful backwash water recycling.
• SBA-IX Technical Advisory: Following an IWA policy decision to utilize a strong base anion exchange (SBA-IX) approach, we continue to provide technical advisory services. This includes developing detailed test plans to secure state regulatory approval for full-scale demonstrations of roll-up regeneration at an impacted municipal well site.
Key Project Approaches
Some of the key issues, concerns, and constraints that we have observed so far are summarized below. We have examined/developed the background documents provided in the RFP, designed, and permitted similar facilities, have visited the sites multiple times, researched the site- and equipment-specific permitting requirements, and have the following initial thoughts. Of course, we will work with CWA Staff, take advantage of their considerable institutional knowledge, and develop the design concepts during the basis of design and final design process. However, we will not be starting from scratch – we have done the work in the pursuit of this Project to consider what needs to be done, developed initial concepts about how to approach the major key project issues, and will carry the momentum that we have established in the conceptual design phase of the Project through final design.
Operations is the Ultimate Client
Water Works Engineers joins CWA Management and Engineering in our shared understanding that “Operations is the Ultimate Client”. Following the design, construction, and start-up of the facilities, CWA Operations Staff takes over the operation of the wells and needs to successfully operate and maintain the new facilities every day for years to come. Both the good, and potentially bad elements designed into the Project become apparent to Operations within the first weeks to months following start-up. WWE has met with CWA Operations Staff on facility tours and will continue to learn Operations’ priorities, preferences, and the constraints imposed upon them in the operation of water treatment facilities. WWE is committed to Operations and their satisfaction of the constructed
facilities. We have scoped additional design review
meetings at each major design deliverable in which key
WWE Engineering Staff will sit down in person with CWA
Operations Staff to gain their input prior and implement their preference and desires into the subsequent design deliverable (i.e., plans, standard details, specifications, Process Control Narrative, and Operation Plans). WWE will schedule these meetings and stress their importance to
Operations early in the design process - when changes are easily made and less costly to implement.

The following area of concern and potential risk have been identified and accounted for by WWE in the approach to the Project as scoped in this proposal.
Item 11.
P r o p o s a l f o r P r o f e s s i o n a l E n g i n e e r i n g D e s i g n S e r v i c e s f o r H e x a v a l e n t C h r o m i u m T r e a t m e n t P l a n t s a t S e v e n W e l l S i t e s 20 Schedule Maintenance
Critical to project controls is the effective and accurate updating and tracking of the project schedule throughout the life of the project. Water Works Engineers’ Project Manager, Andrew Borgic. P.E., takes this to heart. He has completed the detailed base CPM Schedule (including the critical path) for the Project and has included this in the proposal (See Appendix C – Proposed Schedule). This base schedule will be expanded as additional tasks, subtasks, and dependencies present themselves during the life of the project.
The schedule will be updated and presented at each meeting and provided to CWS in .mpp and .pdf formats so that the schedule updates may be utilized as a record to the performance of the project and as a “living document”, useful to WWE and CWA Management Staff. Water Works knows that when project managers control schedule, they control budget.
Site Access
In order to provide CWA Operations, Maintenance Vendors (e.g., well drillers), Chemical Supply Vendors, safe access to and on the site, WWE will perform interviews with CWA Operations and contact chemical supply, filter media, and diesel fuel vendors and perform swept path simulations to assure adequate and reasonable space is provided on site for vehicular and chemical supply/well drilling/equipment vehicles.
Of particular concern to WWE is the provision of adequate space for (1) vehicles/trucks access at Wells 11 and 17 and (2) well maintenance activities at Well 11.
Cost Savings and Control Opportunities
Utilizing our recent project design, construction, and start-up experience on similar groundwater treatment facilities (utilizing RCF, As and Fe/Mn removal facilities, backwash reclaim and equalization tanks, chemical feed systems, and solids handling) we have listed a number of cost saving strategies and opportunities that can be explored by CWA during the preliminary design phase of the Project:
➢ Project Execution
o Seek planning and engineering design reimbursement through DWSRF ▪ Modify the BODR to serve as the “Engineering Report” required in the DWSRF Technical Package o Save time early in design - Combine the Basis of Design Report and 30% Design Deliverables ▪ Provides focused early decision making leveraging Water Works Engineers-Corona’s recent experience (last 6-mos.) in the preliminary design of 15 RCF systems o “Right Staffed” – Water Works Engineers has assembled a Project Team that is experienced in (1) the design of the planned Dixon Station 004 Cr(VI) Treatment Facilities and (2) with each other in a focused team (5-7 years)

o Consistent/Common approach to each of the sites (Std Details, Common layouts, Equip.) o Well Pump – VFD-driven pump motor versus constant-speed pump with pump control valve o Backwash Pump (Well 19)
o Metal Sound Enclosure, Rolling removable enclosure, or CMU-blockwall enclosure/part of Ferrous Building
o Backwash Tank Foundation Design – Ring
foundation with true bottom drain
o Ferrous Storage and Handling – 55-gallon drums,
totes, or permanent tank
o Chemical Feed Pumps - Complete skidmounted systems
o Residuals Handling – Direct to sewer, Equalized
to sewer, sludge hauling, or sludge dewatering
and hauling
o Flexible Design Approach to Residuals Handling –
Provide design capable of easily being modified to
allow for future alternative residuals strategies
(e.g., air gap to local drain inlet box and/or lift
station)
o Site Surfacing – AC paving versus partial gravel surfacing o Treat-to-Waste Line – Operations savings
o Removal of TTW Equalization/Waste tanks through mixing in onsite tanks ➢ Construction
o Gain the Contractor’s Perspective Early - Perform 3rd-Party Contractor constructability review during 30% and 60% design preparation
o Limit the implementation of Owner-furnished equipment to that equipment needed to be procured early to meet schedule – Minimizes coordination and schedule risk during construction Focused Final Design Delivery using Effective Tools
Final Design
Reviews of the construction contract documents and supporting calculations are done at four stages, corresponding to the four design deliverables. At each stage, the drawings and specifications are reviewed according to the check lists provided in the QA/QC Plan. The Project Engineers are responsible for reviewing the QC comments, distributing the comments to Project Team members (including subconsultants) and finally documenting a resolution to each comment.
Level 1 – 30% Design Submittal will check for completeness of the design report, preliminary process and hydraulic calculations, design loading rates against relevant regulations and industry standards.
Level 2 – 60% Design Submittal will check for more detailed items for all design disciplines including General, Civil, Architectural, Structural, Process Mechanical, HVAC and Plumbing and Electrical and I&C.
This check will cover drawings presentation, scales, section call outs, drawing indexes, hydraulic elements, coordination between drawings and specifications, discipline coordination, etc.
Level 3 – 90% Design Submittal will check for all design disciplines including General, Civil, Architectural, Structural, Process Mechanical, HVAC and Plumbing and Electrical and I&C.
Level 4 – 100% Design Submittal will be the final check for all design disciplines including General, Civil, Architectural, Structural, Process Mechanical, HVAC and Plumbing and Electrical and I&C.

The Dominguez 300 (DOM 300) Treatment Plant Project was implemented by California Water Service (CWS) to bring the new well, DOM 300, online to supplement the Dominguez District water system. DOM 300 was constructed with a design pumping rate of 2,000-gpm. The DOM 300 wellsite is a 23,000-square foot site located in a heavy manufacturing zone in the City of Compton.
Corona Environmental Consulting (Corona), in association with Water Works Engineers (WWE) evaluated the water quality of the well and identified treatment needs to meet CWS water quality goals. Contaminants observed above water quality goals included ammonia, manganese, and dissolved oxygen levels dissimilar to Metropolitan Water District (MWD) water.
Water Works Engineers provided the design of the following for the DOM 300 wellsite:
• Well pump with VFD
• Chemical storage and injection systems for aqueous ammonia and sodium hypochlorite for formation of chloramines prior to filtration • Three-cell horizontal pyrolusite pressure filter with automated valves • Backwash reclaim tank with tank level sensors and transmitters • Backwash reclaim pump with VFD
• 1,000-gallon surge tank
• Automated pump-to-waste valve and piping
• Mid-process waste piping with manual valves
• PAX Water Quality Station and Smart Controller (with chlorine analyzer and ORP probe)
• Electrical service and transformer by Southern California Edison • Electrical panel board
• CMU building and site improvements
• Provisions for future breakpoint chlorination tank.
Water Works Engineers prepared a preliminary design report, 60%, 90%, 100% and final design drawings, specifications and bid documents. WWE provided engineering support during bidding, permitting support services, engineering services during construction, and start-up and commissioning support services.

Design/Build of Southern Well No. 6
Manganese Treatment Facility
Gardena, CA
Southern Well No. 6 Southern Well No. 6 (located at 13503 S. Vermont Avenue, Gardena, CA) is a vital component in the Golden State Water Company (GSWC)’s Southwest Distribution System. The well capacity is approximately 1,000 gpm. Manganese levels in the well range from 34 μg/L to 49μg/L, according to lab sampling results during the period of 2010 through 2015. Although the manganese levels are below the Secondary Maximum Containment Level (SMCL) of 50 μg/L there is a potential that manganese will precipitate out in the water distribution system causing colored water and increase sedimentation in the mains.
To address the future potential for manganese precipitation issues in the water distribution system, GSWC hired Pacific Hydrotech/Water Works Engineers (WaterWorks) to design and construct the manganese treatment system at Well No.6. WaterWorks provided geotechnical analysis; surveying, civil, mechanical, and structural design services, and electrical design for:
GSWC furnished 1,000-gpm Pressure Filter System and the Air Compressor 40,000-gal Backwash Storage Tank
100-gpm Backwash Decant Pump
supporting yard piping
Related Electrical and instrumentation improvements
The project required to provide a fully functioning facility with cost-effective solutions and cost-containment methodologies, ultimately leading to a minimized life-cycle cost of all facilities for the desired level of service within relatively short period of time.
WaterWorks worked together with the Pacific Hydrotech in an integrated design process to accommodate the changes in the field, relative to the existing As-builts, and the GSWC’s desire to locate the pressure filter and the backwash storage tank. WWE coordinated survey and geotechnical engineering services and self-performed the structural designs required for the pressure filter concrete support slabs.

Design/Build of Plant 134 Granular
Activated Carbon Improvements
Highland, CA
The East Valley Water District is a California Water District provides water and wastewater services to 103,000 residents within the City of Highland and portions of both the City and County of San Bernardino. The District’s Plant 134 Water Filtration Facility treats local surface water from the Santa Ana River and raw water purchased from the State Water Project. Water Works Engineers provided the basis of design for the design and construction of a new GAC system, feed pumps, piping, related appurtenances, and access road at East Valley Water District’s Plant 134 Water Filtration Facility. Water Works created a project plan and established design criteria and requirements for subsequent final design activities in Phase 1 and Phase 2 of this progressive design-build project.
The main purpose of this project was to reduce disinfection byproduct (DBP) precursors in the form of total organic carbon (TOC) from the treated water postmembrane treatment and prior to disinfection. A new side-stream granular activated carbon (GAC) system will be designed and constructed at the existing WTP, in addition to access improvements to facilitate the large carbon delivery vehicles.
Based on the results of a pilot study performed by Calgon for EVWD, a GAC system capable of treating 4 mgd (50% of the plant capacity of 8 mgd) and operated at a variable flow rate is recommended and is the basis of design.

Town of Gilbert – North Water Treatment
Plant
Gilbert, AZ
The North Water Treatment Plant is a surface water treatment plant located in the Town of Gilbert, Arizona. The raw water quality and quantity is heavily subject to environmental impacts, SRP water resource management decisions, seasonal patterns, and common raw water conditions. As the source water varies seasonally, the facility needed greater treatment resilience to be able to reliably treat a wide spectrum of conditions – including high TOC, high turbidity, differing pH levels, and high bromide.
WaterWorks, as Prime Engineer, led a team of professionals to conduct a source water evaluation, evaluate and select treatment technologies, and develop detailed construction documents to expand and reconstruct the existing facility from 45 mgd to 60 mgd. The team evaluated system conditions and developed a priority list based on various evaluation criteria including reliability, expandability, operability, and maintainability. Cutting edge technologies are being employed at this facility, including ozonation, ballasted sedimentation, biologically active filtration, and post-filter granular activated carbon (GAC) adsorption. • Highlights: Leading the largest water infrastructure project in the state of Arizona and completely reconstructing and expanding an existing operating facility from 45 mgd to 60 mgd.
• Challenges: Due to the extended construction duration (over 7 years), continued inflation, equipment delays, and labor shortages, cost control has been a key consideration. All this has been accomplished while maintain existing plant production.
