Sterling Pump Station Project

About the Project

Western Municipal Water District is investing to secure local water supplies and reduce our region's reliance on water from Northern California. The Sterling Pump Station project is a component of Western's La Sierra Pipeline project and will connect the water produced at the Arlington and Chino Desalters to customers throughout Western's service area.

In addition to the new pump station, this project will include site improvements such as new landscaping, lighting, and security cameras - providing visual and security enhancements to Sterling Avenue.
