DAVID C. MCCOLLOM WATER TREATMENT PLANT (DCMWTP) MEMBRANE BASIN REHABILITATION AND COMBINED FILTER INFLUENT AND BACKPULSE PIPING REPLACEMENT PROJECT

The David C. McColлом Water Treatment Plant Membrane Basin Rehabilitation and Combined Filter Influent and Backpulse Piping Replacement Project involves the replacement and rehabilitation of critical infrastructure at the existing water treatment facility in San Diego, California. The work focuses on upgrading aging components of the membrane basin and replacing deteriorated influent and backpulse piping systems to ensure continued safe and efficient water treatment operations. This project does not expand the facility’s use or footprint but rather maintains its current function at the same location, addressing the degradation of systems nearing the end of their service life. The upgrades are essential to preserve system reliability and compliance without introducing new operational capacity or environmental impact beyond what currently exists. The project is being managed by the Olivenhain Municipal Water District, with engineering oversight provided by Steven Weddle, the Engineering Services Supervisor, who can be contacted at the provided phone and email. The anticipated posting date for the solicitation is June 23, 2026, and the place of performance is clearly identified as the existing plant site in San Diego with the ZIP code 92029. The replacement efforts are designed to be fully aligned with the plant’s present operational needs, ensuring continuity of service while mitigating risks associated with aging infrastructure. No new set-aside classifications or NAICS codes are specified, indicating this is a maintenance-driven initiative rather than a new development.
