Task 5. Additional services (As Needed)
Soto Resources will perform other required tasks for funding related efforts on an as- needed basis, as requested by the City. Soto Resources and subcontracted staff, as assigned, will work closely with the City to communicate with funding agencies regarding City projects to identify funding opportunities and to determine whether or not to proceed with a grant or loan application (also known as Go/No- Go Process). 25 Soto Resources
Professional Funding Services

The City will be responsible for providing project information required to complete funding related tasks. When the City decides to pursue a funding opportunity, a separate proposal or task order for completing the grant or loan application will be provided by Soto Resources to the City , upon request. This is because the level of effort for application preparation depends significantly on both the application requirements and the amount of existing project information available.

Fee Schedule
The table below shows the anticipated Soto Resources team member and bill rate required to perform the proposed services. The services will be performed on an hourly basis, for a total cost not to exceed $200,000 through June 30, 2027. Invoices will be submitted on a monthly basis.

RIALTO WATER

MONTHLY OPERATIONS REPORT

I. EXECUTIVE SUMMARY
Highlights of this month’s Water O&M report include the following:
• The water distribution network achieved compliance with all permit requirements.
• No sample anomalies that require secondary sampling.
• No significant issues with water availability. The purchasing of water remained consistent and daily equalization tanks levels remained at anticipated volume for customer availability.
• The Preventative Maintenance Program, as well as Valve Exercising, continues to identify areas of focus for our Routine Repair and Replacement.

B. Static Water Levels
All City of Rialto wells are sounded each month, both active and inactive well sites.

Depth-to-water is measured from the well head to the static water surface.

Increases in depth-to-water represent a decrease in static water level.

C. Violations
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 236 mg/L for the month of November as compared to 250 mg/L in Octo ber. 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.
52 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. OPRTP meter was turned off in October.

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 . Five valves were exercised in the month of November.

C. Violations
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 236 mg/L for the month of October as compared to 2 50 mg/L in September . 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.
95 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. OPRTP meter was turned off in October.

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 . Five valves were exercised in the month of October.

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 250 mg/L for the month of September as compared to 2 33 mg/L in August. 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 t o 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.

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 Rialto WWTP are taken into consideration when operating the facilities and water sources.

VIII. REVENUE REPORT
A. Revenue Summary
Cash Revenue is compiled and reconciled to the merchant account on a daily basis. Cash receipts and deposits are made daily and internal controls are reviewed regularly to ensure safeguarding of assets and proper recording of all transactions. Total revenue collected in September 2025 is $4,642,000 whereas Non-Rate Revenue is $ 144,000; Utility Revenue is $4,432,000 and Tax / Ambulance Revenue at $66,000.

RWS collects Utility User Taxes and Ambulance Fees on behalf of the City of Rialto.

The total UUT charges collected in September 2025 and September 2024 are $61,000 and $221,000 respectively. The large variance in collection of UUT charges is due to the City exempting UUT charges to the Residential custo mers beginning January 2025 through December 2025. Ambulance Revenue is also collected on behalf of the City of Rialto totaling $5,000 in September 2025 and $4,000 in September 2024. 135
