For Water Subcommittee Meeting June 23, 2025
TO: Honorable Water Subcommittee Members
APPROVAL: John Rossi, Interim Utilities Manager
FROM: Toyasha Sebbag, Assistant to the City Manager
Staff request that the Water Subcommittee provide feedback on the Rialto Biosolids Handling Upgrades Project at the Wastewater Treatment Plant. (ACTION)
RECOMMENDATION
Staff recommends that the Water Subcommittee provide feedback on the Rialto Biosolids Handling Upgrades Project at the Wastewater Treatment Plant.
BACKGROUND:
On March 8, 2022, the City Council (City)/Rialto Utility Authority (RUA) Board approved the Final Construction Work Authorization (FCWA) which included, among other projects, for Rialto Water Services (RWS) to complete a Rialto Biosolids Upgrade Study.
On February 14, 2023, the City/RUA Board approved the FCWA for RWS to complete the 30% design, and 60% design and preparation of a guaranteed maximum price (GMP) for Biosolids Handling Equipment.
The GMP is good until August 27, 2025. The City has contracted with Jacobs Engineering to review the costs for the project as proposed and to determine if replacing the equipment that needs rehabilitation would be less expensive. A draft of the FCWA for the construction costs and Veolia fees for this phase of the project was received last week. RWS has provided an engineer’sestimate cost of $34,910,000. Staff are currently evaluating these numbers.
ANALYSIS/DISCUSSION:
The existing biosolids handling equipment, including sludge thickeners and dewatering systems is over 30 years old, beyond its useful life, and in need of replacement. This equipment processes sludge from the aeration basins and primary clarifier, feeds it to the anaerobic digesters, and then dewaters the digested sludge for drying and off-site disposal.
The proposed scope of work includes:
(1) Replacing two gravity belt thickeners with rotary drum thickeners; (2) Replacing existing belt filter presses with centrifuges; (3) Performing associated site, mechanical, plumbing, and electrical work, including replacing the digester covers with new inflatable covers; and
(4) Modifying pumps and piping to support the new equipment.

9 File #: WS-25-0429, Version: 1, Agenda #:
This Biosolids Handling Upgrades Project would enhance operational reliability, provide redundancy, increase digester gas production, and improve sludge dewatering, which would potentially reduce hauling costs. Integration with SCADA would also support advanced monitoring, automation, and future use of Artificial Intelligence (AI) tools for process and energy optimization.
Staff will provide the Subcommittee an update on the project in anticipation of final details, including the Final Construction Work Authorization (FCWA), costs, fees, and schedules coming to the committee in July.
FINANCIAL IMPACT:
Operating Budget Impact
The proposed action is expected to have a positive impact on RUA’sWastewater Operating Budget, as lower sludge hauling costs are anticipated.
Capital Improvement Budget Impact
Staff is waiting for RWS to provide a cash flow model to ensure funds are available for this and other capital improvement projects anticipated through June 30, 2026.

For Water Subcommittee Meeting June 23, 2025
TO: Honorable Water Subcommittee Members
APPROVAL: John Rossi, Interim Utilities Manager
FROM: Toyasha Sebbag, Assistant to the City Manager
Staff request that the Water Subcommittee provide feedback on posting a Notice Inviting Bids for the Sycamore Avenue Sewer Trunk Line Upgrade Project, from the Sycamore Lift Station to Baseline Road, with an engineer’s estimated cost of $5.52 Million. (ACTION)
RECOMMENDATION
Staff recommends that the Water Subcommittee provide feedback on posting a Notice Inviting Bids for the Sycamore Avenue Sewer Trunk Line Upgrade Project, from the Sycamore Lift Station to Baseline Road, with an engineer’s estimated cost of $5.52 Million.
BACKGROUND:
The Sycamore Avenue sewer trunk line is an 8-inch gravity main serving the east side of Rialto’s sewer service area. Located downstream of the Sycamore Sewer Lift Station at 1965 N. Sycamore Avenue. The proposed project would install approximately 5,300 linear feet of new 15-inch sewer main, which extends from the lift station to Baseline Road.
Due to significant population growth in the area, wastewater flows have increased beyond the capacity of the existing line. Hydraulic modeling in the 2022 Wastewater Master Plan Update identified this segment as a high priority for upsizing, with current flows frequently exceeding 80% of pipe capacity. Mains operating above this threshold are at elevated risk for sanitary sewer overflows (SSOs).
This finding has been corroborated by Rialto Water Services (RWS), operated by Veolia, through closed-circuit television (CCTV) inspections. These inspections involve guiding a track-mounted camera through the sewer pipe to visually assess flow levels and pipe conditions. In this segment, the camera footage confirmed surcharge conditions, where wastewater consistently fills more than 80% of the pipe diameter, further supporting the need for upsizing.
ANALYSIS/DISCUSSION:
Staff request that the Water Subcommittee provide feedback on posting a Notice Inviting Bids for the Sycamore Avenue Sewer Trunk Line Upgrade Project, from the Sycamore Lift Station to Baseline Road.
The engineer’s estimated cost of $5.52 million includes planning, design, construction, and contingency. Staff has requested that RWS/Veolia ensure that bids will be good for at least 90 days.

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 th e 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 disch arges into the BLF and its production is included in deliveries from that shared transmission line when City Well 4A is in service.
53 14
The overall pumping strategy is based on adjudicated rights, well availability, remediation requirements, and quality of so urce, 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.
A. Operational Wells
All wells were operational.
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 . 55 valves were exercised in the month of April.
