Where does the City of Milpitas receive water?

The City has two water suppliers for the City: San Francisco Public Utilities Commission (SFPUC) and Valley Water (VW).

The SFPUC water supply is a combination of Hetch Hetchy water and treated local water. Most of SFPUC’s water is sourced from the Hetch Hetchy watershed located in the Sierra Nevada Mountains. Local water is collected within the Alameda watershed at Calaveras Reservoir and San Antonio Reservoir and treated through filtration and disinfection at the Sunol Valley Water Treatment Plant.

The Valley Water water supply is sourced primarily from the Sacramento-San Joaquin Delta watershed via the South Bay Aqueduct, Dyer Reservoir, Lake Del Valle, and San Luis Reservoir. The water supply is supplemented by local water sources at Anderson and Calero Reservoirs. Valley Water water is treated through filtration and disinfection at Penitencia and Santa Teresa Water Treatment Plants.
