on the Update to the Proposed Water
and Wastewater/Sewer Rate Study.
(ACTION)

Staff requested Feedback Regarding the Update to the Proposed Water and Wastewater/Sewer Rate Study Schedule.

A PowerPoint presentation was provided by Sanjay Gauer. (ACTION)

Questions & Comments
 Mayor Baca inquired whether pipelines that are 60 to 70 years old require replacement and if a timeline has been established for the replacement.

o Stephen Dopudja advised that pipelines in this age category need replacement because they are at the end of their useful life. Otherwise, the City would likely end up cutting into the streets and doing patchwork repairs. A timetable can be obtained from the Public Works Department, which leads the project.

 Major Baca asked if staff have sought grant funds for the CIP projects?

o Mr. Dopudja advised that federal funding is sought after for our projects.

 Mayor Pro Tem Scott requested a report that outlines the sources of the Development Impact Fe es (DIF), specifically identifying which developments contributed to these fees.

 Mayor Pro Tem requested an update on the security project.

 Mayor Pro Tem would like confirmation that the hydrant project that is proposed to be deferred will not pose any fire safety risk for the community and requested input from the fire department.

 Mayor Pro Tem raised the topic of a debt issuance policy and noted that the City currently lacks a formal policy, suggesting that one should be established, as well as a 5-year plan.

9 3

 It was discussed that the city does not receive a d valorem tax to support its capital improvement projects, while some agencies do, such as the West Valley Water District.

 The Prop 218 calendar date was discussed. It was determined that the Prop 218 hearing would go before the City Council on January 13, 2026.

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

TO: Water Subcommittee Members
APPROVAL: Tanya Williams, City Manager
FROM: Toyasha Sebbag, Assistant to the City Manager
Staff request Water Subcommittee review and provide feedback on the Agreement between the City of Rialto and the County of San Bernardino for an additional three-year term (January 1, 2026 - September 30, 2028) to allow continued use of 1,600 acre-feet of Standby Water Lease within the Rialto/Colton Groundwater Basin.
(ACTION)

RECOMMENDATION
Staff recommends that the Water Subcommittee review and provide feedback on the Agreement between the City of Rialto and the County of San Bernardino for an additional three-year term (January 1, 2026 - September 30, 2028) to allow continued use of 1,600 acre-feet of Standby Water Lease within the Rialto/Colton Groundwater Basin.

BACKGROUND
The City of Rialto (Rialto) and County of San Bernardino (County) first entered into Agreement No. 00 -289 on May 20, 2000, authorizing the County to use up to 1,600 acre-feet per year of Rialto’s groundwater rights leased to the Fontana Union Water Company (FUWC) for compliance with Regional Water Quality Control Board Order No. 99-86 (Cleanup and Abatement Order No. 98-96).

In February 2019, the Standby Water Lease between Rialto and FUWC was extended for another 20 years. Both parties agreed to pursue a Consumer Price Index (CPI)-based rate adjustment of up to 5 percent annually, applied to the County’s payment obligations.

The original agreement with the County expired in May 2020, after which the County obtained a two- year extension (through December 31, 2022) approved by the City Council on September 14, 2021. A subsequent Amendment No. 1 extended the agreement through December 31, 2025, allowing continued County use of up to 1,600 acre-feet of standby water and corresponding reimbursements to Rialto.

The adjustments are based upon the accumulative CPI from the beginning of the agreements and carried forward to current. The CPI is based upon the US Department of Labor Bureau of Labor Statistics’Consumer Price Index for all Urban Consumers (CPI-U) and shall not exceed the annual increase of 5%.

The County is continuing good-faith discussions with FUWC and the Regional Board regarding the long-term need for the 1,600 acre-feet allocation and now seeks to extend the agreement through City of Rialto Printed on 10/27/2025Page 1 of 3

long-term need for the 1,600 acre-feet allocation and now seeks to extend the agreement through September 30, 2028, with an option for two additional three-year renewals.

ANALYSIS/DISCUSSION
The proposed Standby Water Lease (effective January 1, 2026) provides the following payment schedule to Rialto:

The County must notify Rialto in writing 30 days before each water year whether it will exercise its right to pump under the lease. Rialto will invoice the County after the close of each water year (September 30), and the County must remit payment within 60 days of invoice.

The agreement maintains the maximum 5 percent annual CPI adjustment permitted under the FUWC lease and remains consistent with Baseline Feeder replacement water costs of approximately $210 per acre-foot.

Both parties reaffirm Rialto’sownership of sufficient water rights within the Rialto/Colton Groundwater Basin to honor the lease and commitment to the Regional Board Order’s compliance objectives.

ENVIRONMENTAL IMPACT
The proposed action is not a “Project”as defined by the California Environmental Quality Act (CEQA). Pursuant to Section 15378(a), a “Project”means the whole of an action, which has a potential for resulting in either a direct physical change in the environment, or a reasonably foreseeable indirect physical change in the environment. According to Section 15378(b), a Project does not include: (5) Organizational or administrative activities of governments that will not result in direct or indirect physical changes in the environment.

GENERAL PLAN CONSISTENCY
Approval of the proposed action also complies with the following City of Rialto Guiding Principles, General Plan Goals and Policies: “OurCity government will lead by example, and will operate in an open, transparent, and responsive manner that meets the needs of the citizens and is a good place to do business.”
Approval of the proposed action also complies with the following City of Rialto Goals and Policies:

Goal 2-29: Protect and enhance Rialto’s surface waters and groundwater basins.

Policy 2-29.1: Work with local water agencies and the State and Federal governments to clean up City of Rialto Printed on 10/27/2025Page 2 of 3

and mitigate perchlorate contamination within the basin.

Policy 2-29.5: Apply methodologies and assign responsibility to protect the quality of groundwater from pollution by landfills and industrial uses.

LEGAL REVIEW
The City Attorney's Office has reviewed the agreement and approved it as to form.

FINANCIAL IMPACTS

Revenues from these invoices are recorded as non-rate revenue within the Trust Accounts.

Capital Improvement Budget Impact

WHEREAS, on December 13, 2022 (Item No. 56), the Board approved Amendment No. 1 to Agreement No. 21-689 between the County and Rialto which extended the contract term by three years to December 31, 2025, to utilize up to 1,600 acre feet of water for compliance with the Regional Board Order for the period January 1, 2023 through December 31, 2025, and to reimburse Rialto for such use as set forth in Amendment No. 1 to Contract No. 21-689; and

WHEREAS, the County is engaged in good faith discussions with Fontana Union Water Company regarding whether the 1,600 acre feet per year is still necessary and the terms for such use, with the County’s position being that it is no longer necessary; and

WHEREAS, to the extent it may be necessary or desirable as determined by the County during its negotiations with Fontana Union Water Company, the County desires to be able to utilize up to 1,600 acre feet of water for compliance with the Regional Board Order for a period commencing on January 1, 2026, as part of the current 2025-26 water year, through September 30, 2028, and to reimburse Rialto for such use as set forth in this Agreement, for a period of three years with the option to extend for two additional three-year periods.

NOW, THEREFORE, in consideration of the foregoing recitals, which are incorporated herein by reference, and the mutual covenants and conditions, the parties hereto agree as follows:

1. Recitals. The Recitals stated above are incorporated herein by reference.

2. Effective Date. This Agreement shall commence upon the effective date of January 1, 2026.

3. Term. This Agreement shall remain in effect through September 30, 2028, with the option to extend the term for two three-year periods, upon mutual written agreement of the parties.

4. County’s Payment of Consideration for Water Rights Granted Under the Standby Water Lease. As consideration for the grant and/or exercise of the standby water rights granted to Fontana Union Water Company pursuant to the terms of the Standby Water Lease, the County shall make payment to Rialto the amount of $65.48 per acre foot charged for making water rights available ($104,768) and an additional payment of $163.71 per acre foot for each acre foot of water drawn from or produced pursuant to such standby water rights (up to $261,936) for a total of $366,704 for the partial 2025/2026 Water Year. 19

For the 2026/2027 Water Year, the County shall make payment to Rialto the amount of $68.75 per acre foot charged for making water rights available ($110,000) and an additional payment of $171.90 per acre foot for each acre foot of water drawn from or produced pursuant to such standby water rights (up to $275,040) for a total of $385,040.

The County will inform Rialto in writing within 30 days prior to the start of the water year the degree to which the County intends to utilize the standby water rights for that water year. The estimation provided by the County does not preclude the County from notifying Rialto during the water year that the County intends to utilize additional standby water rights, which Rialto agrees to accommodate to the extent such rights remain available to Rialto in that water year, up to the amounts allowed under this Agreement. During the Agreement term, the County will pay the respective amount per acre foot charge for making water rights available regardless of whether it utilizes the 1,600 acre feet of standby water rights.

Such invoice shall not be issued until the close of the water year (September 30).

5. Existence of Water Rights. Rialto asserts that it owns water rights in the Rialto Basin adequate to allow it to grant the standby water rights this water year, in an amount sufficient to allow for the production during any Production Curtailment up to 1,600 acre feet of water pursuant to such rights. Rialto acknowledges that it understands that the existence of 1,600 acre feet of water rights in the Rialto Basin, the validity of its agreement to provide water rights in the Standby Water Lease and its intention to abide by the conditions of that Lease are critical to the County’s decision to enter into this Agreement and that in the absence of same, the County would not enter into this Agreement.

6. Indemnification. The County and Rialto shall each indemnify, defend and hold harmless the other and their respective past, current and future officers, directors, employees, volunteers and/or agents from any and all claims, demands, costs or liability arising from or connected with any work done by the indemnifying party under this Agreement, except as otherwise provided by law.

This paragraph shall not apply to those costs and attorney’s fees dire ctly arising from a third- party legal action against a party hereto and payable under the Liability section of this agreement.

Staff requests Water Subcommittee Review and Provide Feedback on the Proposal for Extended Professional Services with Dopudja & Wells Consulting, Inc.

RECOMMENDATION
Staff requests that the Water Subcommittee review and provide feedback on the Proposal for Extended Professional Services with Dopudja & Wells Consulting, Inc.

BACKGROUND:

Dopudja & Wells Consulting has provided professional engineering and management support services to the City of Rialto and the Rialto Utility Authority (RUA) since 2021 under a Professional Services Agreement (PSA). Over time, amendments have been executed to maintain continuity of specialized technical and interim staffing support for the City’s Utilities Division.

As the City continued efforts to permanently fill critical management positions and to sustain momentum on multiple capital and regulatory initiatives, Dopudja & Wells has remained a key technical resource assisting with operational continuity, capital project implementation, and inter- agency coordination.

ANALYSIS/DISCUSSION:

The proposed Seventh Amendment would extend Dopudja & Wells Consulting’s professional services under the City’sPSA to provide additional interim and technical support during the transition to a fully staffed Utilities Department. The scope presented in the consultant’s October 1, 2025 proposal includes four primary tasks:

The proposed services totaling $797,130 cover all four tasks listed above, inclusive of reimbursables and administrative overhead, and span an estimated 6-9 month performance period.

SUBJECT: Proposal to Provide Additional Staffing Support Services Dear Ms. Williams,
Dopudja & Wells Consulting (Dopudja & Wells) understands that the City of Rialto is requesting a proposal to extend additional consulting support services. This proposal includes two primary areas of support as outlined below.

Scope of Work
Task 1. Additional Interim Staffing Support Related to the Utility Department As the City searched to permanently fill the Utility Manager/Director positions, Dopud ja & Wells was requested to provide additional support to the Utility Department. The City is encouraged that it has found a candidate to permanently fill the position. Dopudja & Wells will now be reducing our role as we transition responsibilities over to the permanent Utility Director. Our temporary supp ort effort covers the period from the end of our prior amendment an d is expec ted to occur through the end of February 2026. Durin g this peri od our role will progressively decrease as we transition support over to the permanent Utility Director responsibilities. Dopudja & Wells will control our work and the manner in which it is performed. During this period Dopudja & Wells will continue to have no control over the conduct of the City’s officers, employees, or agents. Dopudja & Wells will not at any time or in any manner represent that it or any of its officers, employees, or agents are in any manner officers, employees, or agents of the City. Dopudja & Wells shall not incur or have the power to incur any debt, obligation, or liability whatever against the Cit y, or bind the City in any manner. No City employee benefits shall be available to Dopudja & W ells in connecti on with the performance o f the scope of wor k pursuant to the Agreement with the City. We are proposing Mr. Stephen Dopudja an d Mr. Jason Pivovaroff will share in the primary duties of providing consulting support to the City. Additionally, the City has requested the services of Mr.

John Rossi at a reduced level, to provide finance, accounting and rate study support. Lastly, the City is experiencing a higher pace of infill/developments, predominantly in the se wer service areas. These include residential, commercial/industrial developments. As a result, additional hydraulic modeling ha s been requested beyond historic levels. All of the work in this work will be performed on an as-needed basis. Below is a table to reflect the anticipated level of support and reductions through February 2026. 27 Tanya Williams

facilities.

The San Bernadino Valley Water District and the County of San Bernardin o Have

reached
several

other
recharge agreements at the County’s flood control facilities.

The cactus b
asin stormwater retention facilities

is
the final facility for such negotiations,
b
ecause of some unique challenges. Although the storm water retention
facilities

are the ideal location for recharging the Rialto

The responsible parties have expressed concern that recharging in the area would
potentially move the contamination plumes. However, the groundwater producers have
made

clear that the
purpose of groundwater basins
is for storage and production

and the requirements of USFW, the O&M outline will be
developed into a
draft O&M Manual
.

For Water Subcommittee Meeting, October 30, 2025
TO: Water Subcommittee Members
APPROVAL: Tanya Williams, City Manager
FROM: Nicole Hemmans, Senior Administrative Analyst
Request to Cancel November 27, 2025, and December 24, 2025, Subcommittee Meetings. (ACTION)
RECOMMENDATION:

Staff requests that the Subcommittee approve the cancellation of the regularly scheduled meetings on November 27, 2025, and December 24, 2025, due to scheduling conflicts with the Thanksgiving holiday and City Hall’s annual holiday closure week, respectively.

ANALYSIS/DISCUSSION:

The Subcommittee is scheduled to meet on the fourth Thursday of each month. The upcoming November 27 meeting falls on Thanksgiving Day, a nationally observed holiday during which City offices are closed. Similarly, the December 24 meeting falls within the City’sannual holiday closure period, during which City Hall is closed.

Canceling these two meetings is consistent with past practices when meetings coincide with major holidays or scheduled City closures. This ensures staff availability, respects holiday observances, and acknowledges the limited public and subcommittee member availability during these periods.

Should any urgent matters arise that require the Water Subcommittee's attention before the next regularly scheduled meeting, staff will coordinate to schedule a special meeting if necessary.

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.
56 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 . Zero valves were exercised in the month of July.

The large variance in collection of UUT charges is due to the City exempting UUT charges to the Residential customers beginning January 2025 through December 2025. Ambulance Revenue is also collected on behalf of the City of Rialto totaling $4,000 in August 2025 and $6,000 in August 2024.

No violations were received during this reporting period.

D. Source Water Total Dissolved Solids (TDS)
Veolia has a goal of maintaining an acceptable blended TDS level between all its sources. This goal is achieved by shifting production to or from the lowest TDS wells or purchased low TDS water while adhering to the overall water supply strategy and meeting system demands. The TDS was 233 mg/L for the month of August as compared to 235 mg/L in July. The TDS levels are below the secondary maximum contaminant level requirements.

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 . 12 valves were exercised in the month of August.
