Source of Water in Berkeley, United States

Berkeley’s tap water is supplied by the East Bay Municipal Utility District (EBMUD). Most of the water comes from the Mokelumne River watershed in California’s Sierra Nevada and is stored in Pardee Reservoir.

EBMUD treats the water at its Orinda Water Treatment Plant before distributing it to Berkeley and nearby East Bay communities. Local East Bay reservoirs can also supplement the supply, especially during dry periods.
