Aqueous Ammonia Storage Tank Lining Replacement Project

The Central Coast Water Authority is preparing to replace the vulcanized rubber lining in the aqueous ammonia storage tank at its Polonia Pass Water Treatment Plant due to internal delamination and degradation at the outlets and flanges. This project is essential to maintain the integrity and safe operation of the tank, which stores critical treatment chemicals used in delivering State Water Project water to retail providers and end users across the County. The work will ensure continued reliable chemical handling and compliance with operational safety standards for the facility. The project is forecasted with a posted date of May 29, 2026, and is located in California, specifically at a site with the zip code 93461. The Central Coast Water Authority, acting as the lead agency, has designated Peter Thompson, Executive Director, as the primary point of contact with availability through email and phone. While no solicitation number or NAICS code has been assigned yet, the anticipated scope focuses exclusively on the lining replacement to address the identified structural issues and extend the service life of the tank.
