Bonita Valley Reservoir Residual Control System

The Bonita Valley Reservoir Residual Control System project involves installing an automated system at Sweetwater Authority’s largest treated-water storage facility, which consists of two 9-million-gallon basins, to maintain a stable chloramine residual by precisely controlling the chlorine-to-ammonia ratio. This system is designed to prevent nitrification, a water quality issue that can arise during warm temperatures, low water demand, and high chlorine consumption, thereby safeguarding the integrity of the local water supply and reducing the need for costly temporary switches to imported water. The Residual Control System will be fully integrated with the Authority’s existing SCADA network to enable continuous remote monitoring, real-time alerts, and operational control, ensuring consistent water quality across the entire system. The installation will utilize existing infrastructure and utility connections within the current disturbed site boundary, with no new ground disturbance or expansion of facility capacity required. The project has been determined to be exempt from full environmental review under California CEQA § 15061(b)(3), the Common Sense exemption, based on its minimal environmental impact. Documentation was filed with the San Diego County Clerk’s Office and the State Clearinghouse, including a Certificate of Determination and Notice of Exemption, both dated in December 2025. While the project is administered by Sweetwater Authority’s Engineering and Operations Department with oversight from Land and Environmental Manager Israel Marquez, the procurement documentation lacks formal contract details such as a solicitation or contract number, pricing, contract type, payment office, accounting codes, or formal inspection criteria. No federal acquisition regulation clauses, packaging or marking standards, invoicing systems like WAWF, or contract administration roles such as COR or COTR were identified. The absence of a defined Section B indicates that the contract value is not publicly disclosed, and the overall procurement appears to follow a streamlined, locally managed process with no indication of competitive bidding or evaluation factors beyond environmental compliance.
