Biosolids Handling Upgrade s Project
at the Wastewater Treatment Plant.
(ACTION)

Update on the Rialto Biosolids Handling Upgrade s Project at the Wastewater Treatment Plant provided by RWS/Veolia. (ACTION)

Questions & Comments
 Peter Luchetti and Megan Matson with RWS/Table Rock distributed an updated PowerPoint presentation on the Biosolids project.

 Mayor Baca inquired about the funding sources for the costs associated with the new technology.

o Stephen Dopudja advised that it is included in the project cost.

 Mayor Pro Tem Scott stated he will support the biosolids project moving forward, based on the updated FCWA totaling $35,598,387, but will not support Veolia earning more than 10%.

 Mayor Baca inquired about the projected timeline for the project's completion.

o Megan stated the project should be completed by the end of 2027.

 Mayor Baca asked if there will be a Project Labor Agreement (PLA) in place?

o Megan Matson confirms that there will be a PLA in place, the same as the S1 project.

 Mayor Pro Tem Scott mentioned that he met with Mr. Luchetti and Sonia regarding PLAs, and it was very clear that PLAs should be in place, even for small projects. He further expressed frustration upon 6 3

learning about a $5 million project without a PLA, despite claims that union wages were paid.

 Mayor Pro Tem Scott advised that it was established that anything over $170,000 would require a PLA.

 Mr. Luchetti stated he will introduce the City Manager , Tanya Williams, to the City’s new representative with the San Bernardino Building Trades Council.

 Ms. Matson suggested that there would be savings if the City were to apply the unused allocation of a prior FCWA to this project.

 City Manager Williams suggested that it is more straightforward to issue a new FCWA, instead of combining the projects, as the available funds for the prior FCWA are unknown.

 Mayor Pro Tem Scott clarified that, citywide, unused funds of a FCWA do not automatically revert to the fund balance.

 Mr. Dopudja provided two options on recognizing the unused portion of a prior FCWA:

o Option one – Issue a credit for the unused portion of the previous FCWA against the new FCWA, offering a savings.

However, consider the accounting challenges.

o Option two – Issue a FCWA for the total project cost and cancel the previous authorizations.

 Mayor Baca inquired if the unused portion of a FCWA can be allocated to a fund designated for other city projects.

 Mayor Pro Tem advised that it should roll back into the budget.

 Mayor Baca asked if the cost of the entire project is an estimate?

o City Manager Williams advised that the Guaranteed
Maximum Price (GMP) is the contractual amount and that
there will not be any increases to the cost.

 Mayor Baca asked if the project cost would increase with the cost of construction.

o Mr. Dopudja advised that the GMP will not increase.

 Ms. Matson requested that an unused portion of a previous FCWA for Digester 1 & 2, totaling $300,000, be reallocated to the Biosolids project before canceling the Digester 1 & 2 FCWA authorization. 7 4

 Mr. Luchetti suggested a Project Cost Accounting reconciliation to the FCWA’s under the Rialto Utility Authority.

o City Manager Williams commented that it is part of a previous discussion that we need to get a better
understanding of the financial management.

 Mayor Pro Tem Scott noted that there has been ongoing discussion regarding the need to place greater emphasis on the financial aspects. He acknowledged that the department has a qualified financial expert, Nicole Hemmans, whose expertise has not yet been fully utilized for this purpose. The conversation on this matter continues.

 Mayor Pro Tem asked if this item will be presented at the next City Council meeting?

 City Manager Williams advises that it can be presented at the next meeting, just as long as the staff report is prepared no later than August 6, 2025.

 Mayor Pro Tem stated he would like to see it happen on August 12, 2025 City Council meeting.

 Mayor Baca and Mayor Pro Tem Scott requested that staff report include that this item was reviewed b y the Water subcommittee and they recommended that it be brought to the council.

The Water Subcommittee’s feedback on their review of the project was to move forward with presenting this item to the City Council for recommendation at the FCWA amount of $35,598,387, and to disclose that there may be a cost saving from reallocating unused funding from a prior FCWA.

WS-25-0499 – Request for Feedback
Regarding the Proposed Water and
Wastewater/Sewer Rate Study Schedule.
(ACTION)

Staff requested Feedback Regarding the Proposed Water and Wastewater/Sewer Rate Study Schedule.
(ACTION)

Questions & Comments
 Mayor Baca asked what the rate increase would be?

o Mr. Dopudja said that we do not know and that would be determined in the rate study process.

 Mayor Pro Tem Scott said he approves of the rate study but wants it to include eliminating the annual lease payment to the City and keeping those funds in the water and wastewater fund.
8 5

 City Manager Williams asked Assistant City Legal, Robert Khuu, whether Prop 218 hearings can be held during a Special Meeting, as the staff report shows the planned hearing date is to be scheduled for November 18, 2025. This is considered a Special Meeting because the regular meeting scheduled for November 11th was canceled due to Veterans Day, and the second regular meeting in November was canceled because it falls on the week of Thanksgiving.

o Mr. Kuu advised that he will confirm.

o0o

WS-25-0502 – Request for Feedback
Regarding Amendment with Soto
Resources for the Preparation of the
Cal OES Hazard Mitigation Grant
Program (HMGP).
(ACTION)

Staff requested that the Water Subcommittee provide feedback on a contract amendment with Soto Resources in the amount of $62,100 for the preparation of the Cal OES Hazard Mitigation Grant Program (HMGP).
(ACTION)

Questions & Comments
 Mayor Baca asked which agency the City intends to apply for generator grant funds.

o City Manager Williams advised that this grant is through the Cal OES Hazard Mitigation Grant Program (HMGP).

 City Manager Williams advised that the total cost of this project increases the project agreement above $100,000, which is why this item will need recommendation from the Water Subcommittee to be taken to the council for approval.

 Mayor Pro Tem commented that we have been discussing this matter for years and asked how West Valley Water District (WVWD) obtained their generators already.

o Staff will confirm how WVWD generators were funded
and provide an update to the Water Subcommittee.

 Mayor Baca expressed the need for staff to have a more aggressive approach in actively seeking out, identifying, and applying for grant opportunities.

The Water Subcommittee’s feedback was to move this item forward for recommendation to the City Council.

Questions & Comments
Future Extraterritorial Agreements

 Mayor Pro Tem Scott requested a more accurate report on contaminants in the City of Rialto’s water supply, by well site location. He expressed that he was not satisfied with the presentation on the Public Health Goals report. Additionally, MPT mentioned he disagrees with RWS, stating that we are blending water to get rid of arsenic. We should be looking for a treatment system as opposed to stating we’re blending water . Mayor Pro Tem requested an update and would like a discussion item on this matter.

 Mr. Luchetti brought to the attention of the Water Subcommittee that a reconciliation is needed on the Extraterritorial Agreements for two specific reasons:

1. ETA Revenue collection.

2. Liability purposes. If RWS/Veolia is responsible for a location, they need to be made aware.

 Mayor Pro Tem Scott requested an update on the status of the ETA reconciliation.

 Mayor Pro Tem Scott requested an update on the project located at 2245 Valley Blvd.

For Water Subcommittee Meeting September 18, 2025
TO: Water Subcommittee Members
APPROVAL: Tanya Williams, City Manager
FROM: Nicole Hemmans, Senior Administrative Analyst
Staff Requests that the Water Subcommittee Provide Feedback on the Update to the Proposed Water and Wastewater/Sewer Rate Study.
(ACTION)

RECOMMENDATION
Staff recommends that the Water Subcommittee provide feedback on the update to the proposed Water and Wastewater/Sewer Rate Study.

BACKGROUND
On July 23, 2024, the City Council/Rialto Utility Authority (RUA) Board adopted a one-year rate adjustment, effective January 1, 2025, for water and wastewater/sewer services. The one-year rate was based on a five-year financial projection. Staff were directed to return in 2025 with an updated rate analysis for Council/RUA Board reevaluation.

In accordance with the City Council’sdirection to return in 2025 for a reevaluation, staff is preparing to present an updated analysis to the City Council/Rialto Utility Authority (RUA) Board to reassess the water and wastewater rates. On July 24, 2025, staff shared a proposed schedule for the rate study with the Water Subcommittee and requested feedback to support the development of the updated rate analysis.

ANALYSIS/DISCUSSION
Staff and RWS are working with financial consultant Sanjay Guar and his team at Water Economics to prepare a financial analysis and rate study to determine the potential rate increases necessary for the Rialto Utility Authority to operate and project funding, and to be in compliance with the 2012 Concession Agreement. The five-year analysis considers projected expenditures, Capital Improvement Program (CIP) projects, cash reserves, potential long-term debt financing, and debt coverage requirements.

City staff, consultants, and RWS principals plan to update the Water Subcommittee on the status of the rate study, the projected timeline for a 218 hearing for the Council to consider rate increases, and to seek input and feedback on the various key factors in the analysis, such as:
· Water CIP projects in the next five years
· Wastewater CIP projects in the next five years
City of Rialto Printed on 9/15/2025Page 1 of 2
powered by Legistar™
12 File #: WS-25-0595, Version: 1, Agenda #:
· Any potential financing needs for selected capital projects · Trustee coverage requirements
· Debt coverage requirements
· RUA reserve balances and usage
· The desirability of a multi-year rate increase for strengthening rating agency and future long- term debt positions, and lower issuance costs
· Final determination of CIP projects to be included in financial analysis Water Economics will present its preliminary analysis and identify any outstanding assumptions, data needs, or directions required to complete the study, per the attached PowerPoint presentation.

Included in the packet is RWS’s2025 CIP project’spresentation that provides background for the various projects analyzed as part of the rate study financial analysis. Though staff do not intend to go through the presentation at the meeting, it does provide detailed information on each project.

Further, staff will discuss the remaining elements of the process and schedule with the Subcommittee through to the 218 hearing.

Once the Subcommittee provides feedback and direction, the team will finalize the rate analysis and related rate adjustments for review at the next Water Subcommittee meeting. A draft Proposition 218 notice will also be presented at that time for Subcommittee review. This draft will be subject to further refinement prior to distribution to RUA customers. The notice will include the proposed hearing date and time, along with information on protest procedures, as required under Proposition 218.

34 CIP Progress Update 2012 to 2025
Rialto’s Wastewater Utility has significantly progressed on the ”Liquids” side, with the investment in S1, and is about to progress on the “Solids” side, with the approval of the Biosolids Project. The Collection Network condition and Master Plan growth projections defines much of the need in Wastewater. Rialto’s Water Utility needs now center around a Distribution Network with several 40-50-year old Water Mains, plus associated metering, storage, and wells capacity

Profiles
40 WWTP Biosolids Upgrades Project
Wastewater Priority CIP (Status: APPROVED, Reserve-Funded) Description
Replace existing Belt Presses #1 and #2 with new Dewatering equipment. AECOM reviewed five technologies and identified Centrifuge technology as having the best lifecycle value. Replace existing Gravity Belt Thickeners #1 and #2 with new sludge thickening equipment. AECOM reviewed five technologies and identified Rotary Drum Thickeners as the best-value technology because of relatively low capital and operational costs, common use in the industry, a record of high performance, and low level of technological complexity. Bring Digester #1 online to allow Digester #2 to be cleaned, inspected and repaired. Digester #1 was last retrofitted in 2003 and has been inoperable for several years. Digester #2 Dystor lid is past its expected service life and is showing major wear. Any disruption in the operation of Digester #2 and its aged lid would burden the project with extensive cost in emergency repairs and rental equipment. Dystor covers will be also be replaced. The holding tank cover was removed in 2021 due to rust damage including multiple holes which greatly compromised the cover’s integrity. SCAQMD has required that it be replaced with a fixed lid. Furthermore, additional storage tank mixing is required to keep solids in suspension within the tank and provide a consistent and uniform feed to the new dewatering facility.

Fiscal Year 2025-26
Total Project Cost $36,972,421 Already Spent: $1,374.034 FCWA Amount: $35,598,387 Condition Score 5
Criticality Score 5
Status Approved, Reserve-Funded
Notes:

The Centrifuge system was identified as the best-value technology because of relatively low capital cost, common use in the industry, high record of performance, and relatively low technological complexity. Most importantly, centrifuges remove 6% more water than other technologies, producing lighter and drier cake. If installed at the plant, centrifuges would save an estimated $120,000 per year on hauling costs over Belt Filter Presses, noting Jacobs estimated significant additional annual savings. 41 Upsizing Sewer Mains in Sycamore Ave. and Baseline Rd.

Reason for inclusion
Service line laterals installed in the late 1980 to late 1990’s had a high rate of failure less than a decade after their installation due to failures in the plastic laterals. This project will allow control of replacement rather than expensive mitigation of failures. Over the years, 17% of the service lines have been replaced with copper. This project would focus on the remaining 115 service lines, 10 hydrant laterals and hydrants, and 24 service valves that require replacement. 66 Service Line and Hydrant Lateral Replacement on Palm, Orange, Olive and Date Streets Water CIP

Defer/Caution
Reason for inclusion
World War II era lateral piping is still in service and must be replaced as a large project before failure. This pipe has exceeded its expected service life and some failures have already occurred. Historically, there have been over 40 laterals that have been replaced due to leaks, but the remainder of the lines should be scheduled for replacement as one project. This is approximately 7,000 linear feet of piping, 340 service lines and meters, 40 hydrant laterals and hydrants, and 107 valves. 67 APPENDIX Additional

Reason for inclusion
The Regional Water Quality Control Board (RWQCB) has raised concerns that a reliable backup power system is not available at the WWTP . Plants 1-4 and 5 are not in a common electrical loop, and it is currently impossible to support the whole plant with emergency backup generators. Plant 5 electrical connection powers all the processes except the Disk Filter and tertiary treatment, which is still fed from the Plant 1-4 circuit. A single electrical loop is required to connect to all critical equipment and processes in the Rialto WWTP . This project will also provide the electrical infrastructure needed to support any new asset e.g. CoGen use of methane to produce power. 71 City of Rialto

VI. WATER QUALITY COMPLAINTS
No complaints were received during this reporting period.

VII. OPERATIONS UPDATE
The overall operational strategy is to meet the daily water demand. The City of Rialto water system has six operational wells, one of which is owned by the County of San Bernardino and operated by Veolia; Oliver P. Roemer Treatment Plant (OPRTP), which is jointly owned by the City (25%) and West Valley Water District (WVWD); purchased water through the Baseline Feeder (BLF) system from San Bernardino Valley Municipal Water District (SBVMWD); and, if required to meet demand, additional water can be supplied by the City of San Bernardino (CSB) through the BLF for emergency supply only with no guarantee of actual delivery. Water produced from City Well 4A discharges into the BLF and its production is included in deliveries from that shared transmission line when City Well 4A is in service.
98 12

The overall pumping strategy is based on adjudicated rights, well availability, remediation requirements, and quality of source, cost to operate, and varying weather conditions. TDS effluent concentrations for the City of Ria lto WWTP are taken into consideration when operating the facilities and water sources.

A. Operational Wells
EW-1 well was out of service due to pump issues.

B. Valve Activity
On the basis of information collected in 2019, Veolia now has a baseline assessment of all valves and has initiated a new cycle of valve exercising . 48 valves were exercised in the month of June.
