Summary
The Solar Dryer Conveyor project consists of the replacement of four conveyors at the “dry end” of the Solar Dryer and modifying the discharge chute. These conveyors transfer the processed sludge from the solar drier into the sludge loadout building where they are discharged into semitrailers for offsite disposal.
Justification
This system is a single point of potential failure and needs to be fortified. During times of wetter solids, the current system conveys the wet solids to the end without much drying.
Background
The project consists of replacement of four conveyors at the “dry end” of the Solar Dryer. The conveyors on the “dry end” of the dryer that feed the truck loadout facility were sized for dryer solids. The solar dryer feed conveyors have sufficient capacity (provided the sludge is fairly dry, >50%). However, if dewatering equipment produces wetter solids, if a solar dryer bay is offline, or in periods of colder weather, wet solids could be conveyed from the wet end to the dry end without much drying occurring. Due to this potential, these conveyors should be replaced to allow for similar capacities as the “wet” feed conveyors. Also, the discharge chute at the end of the solar dryer needs to be modified to prevent solids bridging at times of the year.
It is recommended that with the replacement of the conveyance system, the chute should be modified to be wider and reduce the potential for “bridging” of solids above the conveyor.
Additionally, it is recommended to have spare motors and parts to keep this system running.
Schedule
Projected completion date for this project is by the end of Fiscal Year 2025-2026. Design contract has been awarded, and design is currently at the 90% phase. Completion of design is anticipated soon and will then be posted on Planet Bids for solicitation of bids for construction.
Once bids are received, we will be back before the Board for contract award.

Summary
Improve air exchanges in the blower building for blower operations.
Justification
The current blower building has limited ventilation filtration and no temperature controls.
During summer months blowers fail due to increase heat. To mitigate the heat, doors and windows are opened (to reduce heat), but dust is then introduced resulting in bearing failures.
Both heat and dust are to be addressed through this project.
Background
The blower building currently has no forced ventilation. As such, air is pulled into the room via the suction of the blowers that are in operation. The blower room has louvers with filters, but during warmer temperature periods, the room gets too hot for blower operation. To resolve this issue, the garage door is opened to cool the room. Opening this door, however, causes dust to enter the room which is causing operation issues with the blowers. It is recommended that a climate control system be installed to keep temperatures and dust in an acceptable range for blower operation.
This can be accomplished with a twofold approach as follows:
1. A combined intake plenum system should be incorporated to provide direct air feed to each of the blowers. This will be done by adding a plenum intake structure to the north of the building, including inlet filters. All blower intake air will pass through this structure and then ducting will be provided into the room to direct pre-filtered air to each of the blowers.
2. With the intake blower air separated from the room ventilation, either a cooling system using air conditioning or evaporative cooling can be used for the air in the room.
Thus, the blowers will have sufficient filtered air flow to each unit and the room will be cooled sufficiently to keep the electronics and motors cool enough to allow for normal and consistent operations.
Schedule
This project is planned to kick off in May 2025. It will run in concert with the Blower Replacement project as they are interconnected.

Summary
Replace three turbo blowers associated with the activated sludge process.
Justification
Over the past few years, WRCRWA has experienced failures of the existing HIS Turbo Blowers.
During the most recent failure we were made aware that HSI equipment is no longer supported, and replacement parts are non-existent.
Background
WRCRWA is currently equipped with five turbo blowers that support the aerobic biological process. These five blowers vary in age and manufacturer. In 2012 (or so), WRCRWA supplemented its aeration capacity within the oxidation ditch by adding diffuser grids and three turbo blowers. Those original three turbo blowers were manufactured by Houston Service Industries (HSI). HSI was subsequently purchased by Atlas Copco. During the 2017 plant expansion and addition of another biological reactor, two more turbo blowers were installed.
These two “newer” turbo blowers were manufactured by APG-Neuros.
Over the past few years, WRCRWA has experienced failures of the HSI blowers (typically related to the air bearings and dust). In 2023, HSI blower #2 experienced an electrical component failure and subsequent mechanical failure. Through this failure and attempted repair, Atlas Copco has notified WRCRWA that the HSI product line is no longer supported and that replacement parts are non-existent. Atlas Copco manufactures a similar product and as they replace existing HSI blowers, those used units and being scavenged for parts to make repairs on other HSI blowers.
WRCRWA is now faced with needing to replace the three HSI blowers (before failure) to ensure availability of adequate air in support of the biological processes. It is in WRCRWA’s best interest to investigate all blower technologies to ensure integration with the remaining two APG-Neuros blowers along with efficiency and ultimate biological air demands.
Schedule
This project has kicked off and design proposals have been received from two firms. Staff are currently evaluating the proposals and will be seeking contract award shortly. This project may span two fiscal years depending on equipment considerations and the availability of replacement equipment.

Capital Project No. 4: Medium Voltage Switchgear
Allocation: Treatment
Estimated Total Cost: $3,138,000
Budget Carryover from Fiscal Year 2024-2025 $180,000
Additional Budget Need in Fiscal Year 2025-2026 $0
Summary
Replace the medium voltage switchgear and place it in the existing electrical building.
Justification
The existing outdoor medium voltage switchgear is 26 years old and is becoming obsolete. It is due for replacement and should be relocated inside the newly built Electrical Building to provide a better environment conducive to such equipment.
Background
Due to the age of the gear and it being installed outdoors, it is recommended that this equipment be replaced to ensure it can be maintained and operated properly in the foreseeable future. A new electrical building has been constructed and the low voltage switchgear was moved into this building. There is room for a new medium voltage switchgear to be installed in this building also.
Depending on the outcome of the blower investigation, dewatering replacement study and low voltage load study, the medium voltage system might be impacted. The request would be for $190,000 during Fiscal Year 2024-2025 with replacement being in Fiscal Year 2026-2027. Design is anticipated to be complete during Fiscal Year 2025-2026.
Schedule
This project is planned to kick off in July 2025.

Additional Budget Need in Fiscal Year 2025-2026 $3,062,500 Summary
Replace the three existing Andritz centrifuges.
Justification
Dewatering sludge is a critical component of biosolids management. Over the past few years, the Centrifuges at WRCRWA have experienced numerous failures resulting in decreased operating cycles. Limited dewatering capacity jeopardizes the treatment plant’s ability to maintain regulatory compliance.
Background
During the later stages of the plant expansion design, it was surfaced that the original centrifuges were outdated and no longer serviceable. The design team sought replacement equipment that would meet the needs of the facility while also fitting within the existing footprint of the original equipment. Andritz centrifuges were selected and installed during the plant expansion.
While the existing Andritz centrifuges have met the needs of the facility, they are being pushed to their limits. The centrifuges are being ran at the far end of their speed rating to achieve decent % solids concentration while maintaining desirable centrate quality. The units are being stressed resulting in reduced component life and increasingly sever failures.
With the units suffering a higher rate of mechanical breakdown, very rarely do we have three units available. This has resulted in increased run times for the other two units available. An investigation of best available technologies and based on current WRCRWA sludge conditions, staff recommend replacing the existing centrifuges to gain greater operational redundancy and productivity.
During Fiscal Year 2025-2026, the ask is for $3,062,500.

Summary
Replace the existing treatment plant emergency generator.
Justification
Generator age as well as various component failures over the 26-year period help drive the need for asset replacement consideration.
Background
WRCRWA is equipped with an emergency stand-by generator to provide power to the plant processes should the need arise. The existing Caterpillar brand stand-by plant generator houses a TIER 2 engine that is 26 years old. PSP, weather, accidental and routine power outages have been a recurring theme at the WRCRWA plant. This uncertainty coupled with asset depreciation accompanies a level of risk for our stand-by power reliance. Generator age as well as various component failures over the 26-year period help drive the need for asset replacement consideration. From a risk and resilience perspective, this unit presents a higher potential for failure. Additionally, the emissions rating is very low when compared to the SCAQMD best available technology today (TIER 4F engines).
During Fiscal Year 2025-2026, the ask is for $1,370,000.
Schedule
This project is planned to kick off in July 2025. In recent discussions with Caterpillar, replacement generators have a lead-time greater than 52 weeks. Our intention is to perform a load study to understand potential future energy demands (associated with dewatering equipment and upsizing of blowers) then solicit proposals for the generator replacement. This project will span two fiscal years based on equipment availability.

Summary
Rehabilitate Primary Clarifier No. 2
Justification
Primary clarifier removes the lighter materials that float to the top such as fats, oil and grease (FOG) as well as heavier materials that sink to the bottom (sludge). FOG and the sludge collected from the primary clarifier are conveyed to the anaerobic digesters for additional stabilization. A primary clarifier is considered the most energy efficient way to remove the biochemical oxygen demand of the wastewater, lessening the energy load on downstream processes such as bioreactors and blower systems. Maintaining the primary clarifiers in well-functioning order would reduce the overall energy footprint of the plant as well as increase the likelihood of maintaining NPDES and AQMD permit compliance.
Background
Primary Clarifier No. 2 is one of two 95-feet diameter primary clarifiers that were constructed in 2017 and has been in service for 8 years. During a routine preventative maintenance inspection after cleaning, the staff discovered a substantial level of corrosion on the sludge collection arms, scum baffle and center supporting ring. A consultant was hired to document the existing condition and to validate staff observations. Staff, along with the consultant, recommend rehabilitating Primary Clarifier No. 2 which consists of repairing/replacing corroded structural members of the sludge collection system, center ring, and scum baffle along with sandblasting and recoating all steel elements.
During the Fiscal Year 2025-2026, the ask is for $500,000.
Schedule
The project is planned to kick off in July 2025.

Capital Project No. 8: InforFSM Implementation – WRCRWA’s Cost Participation Allocation: Treatment
Estimated Total Cost: $245,550

New Budget Need in Fiscal Year 2025-2026 $245,550
Summary
WRCRWA’s allocated share of costs related to the implementation of the financial software Infor Cloud Suite Financials (InforFSM).
Justification
In Fiscal Year 2024, Western Municipal Water District (WMWD), WRCRWA’s administrator, successfully implemented the new financial software, InforFSM, in anticipation of the discontinuation of support for the existing Lawson Version 10 system by its developer in early 2026. Since WRCRWA also uses the same financial software, it is necessary for WRCRWA to share in the implementation cost alongside WMWD.
Background
In June 2019, Western Municipal Water District (WMWD) began the search for a replacement for its financial software due to the upcoming discontinuation of support for Lawson Version 10 after April 2026, along with the cessation of support from Microsoft Server in October 2023. In August 2022, WMWD selected Infor CloudSuite Financials, a subscription-based, multi-tenant software platform, as the new system. The implementation of InforFSM commenced in late 2022 and successfully went live on April 29, 2024.
Since WRCRWA also uses the same financial software platform, it is necessary for WRCRWA to participate in the implementation costs alongside WMWD. The total cost of the InforFSM project implementation is $3,277,045, with WRCRWA’s share amounting to $245,550, or 7.49%, based on the ratio of WRCRWA’s Fiscal Year 2023–2024 operating expense budget compared to that of WMWD.
Schedule
The project has been completed. WMWD is seeking reimbursement from WRCRWA in Fiscal Year 2025-2026.

Capital Project No. 9: South Regional Pump Station (SRPS) Emergency Pump Allocation: Conveyance

Budget Carryover from Fiscal Year 2024-2025 $214,000
Additional Budget Need in Fiscal Year 2025-2026 $0
Summary
Design, purchase, and installation of a standalone diesel bypass pump at the SRPS.
Justification
Currently there is no back up power at the SRPS. By design, in the event of a power outage, the wet well fills and if power is not restored quickly, raw sewage overflows into the Inland Empire Brine Line (Brine Line). Numerous improvements and upgrades have been implemented at the SRPS and WRCRWA Treatment Plant since 2016 to increase the overall system redundancy and reliability. The goal of the improvements/upgrades are to prevent future sewage overflow into the Brine Line located adjacent to the SRPS.
Initially, installation of a standalone diesel bypass pump was considered as it would provide additional redundancy and reliability to the sewage collection system. The pump would allow WRCRWA to maintain independent hydraulic control in the event of mechanical and/or electrical equipment failures at SRPS allowing the SRPS to continue to pump flows to the WRCRWA Treatment Plant rather than discharging them to the Brine Line. However, due to design parameters and FEMA special requirements, the available bypass pump was found to be inadequate, leading to the selection of a permanent generator as the most cost-effective alternative solution.
Background
The SRPS serves the City of Riverside, Home Gardens, City of Norco, and City of Corona by pumping wastewater from these cities just over three miles to the WRCRWA Treatment Plant.
Average daily pumping flow is 3 MGD.
Orange County Sanitation recently objected to un-planned and unnoticed sewage flows in the Brine Line and added a requirement to the Santa Ana Watershed Project Authority’s (SAWPA) discharge permit that required development of a plan to incorporate robust redundancies to prevent discharges to the Brine Line.
The WRCRWA Treatment Plant was designed to rely on the Brine Line and ultimately Orange County Sanitation District as a back-up if there were problems that WRCRWA’s system could not handle. This option provides for redundancy against failure due to electrical issues.
However, after exhaustive analyses, the preliminary design revealed that the previously selected emergency bypass diesel engine pump did not meet the project’s design parameters. As a WRCRWA Pay-go Capital Improvement Projects
Fiscal Year 2025-2026 Budget
result, a permanent generator has been chosen as the most feasible and cost-effective alternative.
Schedule
A grant was awarded on February 3, 2023, from the Hazard Mitigation Grant Program in the amount of up to $938,349 which was initially estimated to cover up to 75 percent of the design, purchase, and installation costs for an emergency bypass diesel engine pump.
A grant application for additional funds to support the emergency generator is in progress.
Additionally, staff are in the process of securing an extension and seeking additional grant funding to address the increasing cost of construction, equipment and material.
The expected completion date for the project was originally in Fall of 2025. However, due to the change of the scope of work, the expected completion date is currently unknown.

Summary
Western Riverside County Regional Wastewater Authority (WRCRWA), under the administrative authority of Western Municipal Water District (WMWD), is requesting a field condition assessment of the WRCRWA wastewater treatment sewer conveyance system pipeline segments and manholes from the Arizona flume to the South Regional Pump Station notwithstanding any related siphons or force mains.
Justification
To protect system operations, maintain regulatory compliance related to the Sewer System Management Plan, and to ensure that WRCRWA is capable of forecasting asset failures as well as establishing appropriate asset replacement reserves, WRCRWA will evaluate, and as well as grade, based on field evaluation, the existing asset condition for 6.8 miles of shared sewage trunk line segments and manholes.
Background
As part of the linear asset management program, condition assessments are required to meet compliance requirements, understand current needs and prepare for future costs. This conveyance system has never had formal condition assessment. This bassline information will provide member agencies with a clear understanding of the maintenance system.
Schedule
This project is scheduled for public bidding in June with work to commence in July of 2025.
Anticipated completion is 6 months contingent on associated bids.
