Removal, Disposal, and Installation of Filter Media in Filters 1, 2, and 3 at Water Treatment Plant No.2, ACWD Job 21509

The Alameda County Water District is preparing to replace the deteriorated filter media in Filters 1, 2, and 3 at Water Treatment Plant No.2 in Fremont, California, where the existing media has been in service since 2011 and has degraded to a point that compromises reliable drinking water treatment. The project involves the complete removal and legally compliant disposal of the old media, followed by the installation of new filter media to restore the filtration system’s performance. In addition to the media replacement, in-kind components and sealants within the filters will be substituted to ensure structural integrity and operational efficiency, bringing the facilities back to optimal condition without altering their original design or capacity. The project is designated as Job 21509 and is managed by the Alameda County Water District with the place of performance located at 94538 in Fremont. Primary points of contact for inquiries are Cristina Pena, Engineering Supervisor, and Cynthia Ha, Associate Environmental Engineer, who can be reached via email or phone for further details. The project was posted on June 29, 2026 as a forecast, indicating planning and procurement activities are underway, though specific solicitations or award details are not yet available. The work is critical for maintaining compliance with drinking water standards and ensuring the continued safe and reliable production of water from the State Water Project.
