Fiscal Year 2026-2027 Budget
Capital Project No. 1: Blower Replacement and Air Intake/Ventilation Modifications Allocation: Treatment
Estimated Total Cost: $2,171,000

Additional Budget Need in Fiscal Year 2026-2027: $300,000
Summary
Replace three turbo blowers associated with the activated sludge process and address any conditions within the existing blower building that negatively impact the operation of the blowers (heat/dust).
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. Additionally, the blowers have suffered failures associated with dust and heat within the blower room.
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.
Additionally, climate conditions within the blower room will be addressed to minimize heat buildup and reduce dust intrusion into the space thus improving the operability of critical equipment.
During Fiscal Year 2026-2027, the ask is for $300,000.

Schedule
WRCRWA awarded a design contract to N2W for the replacement blowers and air handling modifications. WRCRWA has pre-purchased replacement blowers from APG Nueros and expects delivery in late FY 2026. Construction should begin in late FY 2026 and carry over into FY 2027.

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 FY 2025 with replacement being in FY 2027. Design is anticipated to be complete during FY 2026.
During Fiscal Year 2026-2027, the ask is for $2,948,000.
Schedule
The design of replacement medium voltage switchgear is anticipated to begin in the summer with construction taking place in FY 2027.

Budget Carryover from Fiscal Year 2025-2026: $2,978,000 Additional Budget Need in Fiscal Year 2026-2027: $1,000,000
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 severe 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 2026-2027, the ask is for $1,000,000.
Schedule
A design contract was awarded to N2W to analyze dewatering options for WRCRWA. Staff are currently working through the technical evaluation of dewatering options with anticipated design wrapping up in FY 2026. Construction should begin in FY 2027 and likely carry over into FY 2028.

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).
Schedule
An electrical load study has been completed, and verification of existing and future electrical loads are understood. We are currently pausing this project while pursuing a grant application to offset costs. Once the grant opportunity is confirmed, design of the replacement will proceed. 106

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.
Schedule
Albert A. Webb and Associates has been awarded a contract engineering support for the rehabilitation of Primary Clarifier #2. WRCRWA has awarded a purchase order to WesTech to provide for the purchase of a new clarifier drive assembly. We anticipate construction kicking off in late FY 2026 and carrying over into FY 2027.

Allocation: Treatment
Estimated Total Cost: $2,535,000
Budget Carryover from Fiscal Year 2025-2026: $0
Additional Budget Need in Fiscal Year 2026-2027: $500,000
Summary
Construct a Maintenance shop/Warehouse to support repair of plant equipment and storage of spare parts necessary to keep the treatment plant operational.
Justification
The addition of a maintenance shop/warehouse building will provide ample space on site for performing maintenance and repairs of equipment at the existing plant site along with protected storage of spare parts. Currently there is a relatively small area attached to the Administration Building that provides some space for parts storage and maintenance of equipment. The space is not large enough for either storage or maintenance activities. A dedicated facility is required to provide sufficient area for both of these functions.
Background
Originally, the WRCRWA treatment plant was built with a small maintenance shop/storage area at the back of the administration building. This space was envisioned to support the original facility. Over time, the facility has grown both in size (expanded from 8.0 MGD to 14.0 MGD) while also growing in complexity. WRCRWA has also noticed changes in availability of spare parts needed to support the maintenance and repair of equipment critical to the treatment plant’s operation. This has driven a significant investment by WRCRWA in spare parts.
WRCRWA has outgrown the original space provided for maintenance and storage. Staff have been utilizing all available indoor space throughout the facility for storage as well as brought in several storage containers to help house spare parts and allowing the original space to be used for maintenance activities.
During Fiscal Year 2026-2027, the ask is for $500,000.
Schedule
The project is planned to kick off in July 2026. This initial phase would cover design and site conditions with construction anticipated the following year. 108

Budget Carryover from Fiscal Year 2025-2026: $100,000
Additional Budget Need in Fiscal Year 2026-2027: $450,000
Summary
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 needs.
During Fiscal Year 2026-2027, the ask is for $450,000.
Schedule
This project was published on Planet Bids with only one firm proposing. Staff are currently working out details and will come back to the WRCRWA Board for award of contract. We anticipate the condition assessment start in late FY 2026. 109
