Western Water's Recycling Facility Recycled Water Pond Erosion Prevention Project

The Western Water's Recycling Facility Recycled Water Pond Erosion Prevention Project, managed by the Western Municipal Water District, focuses on providing permanent repairs and improvements to the deteriorating slopes of the Recycled Water Storage Pond. Located at 22751 Nandina Ave, March Air Reserve Base, California, the project aims to address existing erosion and prevent future occurrences. A critical requirement is that all activities must be performed without interrupting the operation of the storage pond to ensure continuous facility operation and the uninterrupted distribution of recycled water to customers. The project is structured in two phases: Phase 1 targets slope improvements near the secondary effluent equalization basin to protect the concrete liner and the slope between the recycled water and effluent ponds, while Phase 2 covers the remaining storage pond slopes. Depending on the selected slope protection alternative, such as riprap, the project may require the installation of a bypass system for a temporary berm. The work is guided by a Preliminary Design Report from Lee + Ro and a Geotechnical Investigation Report from Universal Engineering Sciences. Environmentally, the project is classified under CEQA categorical exemptions for existing facilities, replacement or reconstruction, and minor land alterations, and it remains consistent with the Public Facilities designation of the March Area Plan.
