Clearwell Replacement Project

The Clearwell Replacement Project, managed by the SWRCB Division of Drinking Water District 14 for the City of Poway, involves the comprehensive replacement of the 10 MG clearwell at the Lester J. Berglund Water Treatment Plant in Poway, California. The scope of work includes replacing the existing floating cover, liner, overflow structure, and appurtenances, with the final clearwell replacement consisting of two 4 MG prestressed concrete tanks. To maintain operations during construction, a temporary bypass system will be implemented, featuring two 1.4 MG above ground storage tanks at the Lake Poway Recreation Area softball field, an above ground pump station at the plant, and associated pipelines. Additionally, a permanent underground bypass pipeline will be installed between the plant and the Lake Poway Road Transmission Main. This project is currently categorized as a forecast under NAICS code 237990, with a posted date of June 29, 2026. It has been granted a Notice of Exemption under Class 2 and Class 11 Categorical Exemptions of the California Code of Regulations, as the work involves replacement without capacity expansion and the use of temporary accessory structures. All temporary facilities are slated for removal upon project completion. The primary point of contact for the project is District Engineer Joseph Guzman.
