About

EBMUD, established by a vote of the people in 1923, has a proud history of providing high-quality drinking water for 1.3 million customers in Alameda and Contra Costa counties. The District's award-winning wastewater treatment protects San Francisco Bay and services 650,000 customers.

Mission

From Pardee Reservoir and through a web of pipes and facilities, EBMUD supplies mountain water to East Bay customers. Every day of the year, EBMUD treats wastewater before it is discharged to the bay. The District recycles water, produces energy from waste and works with residents and businesses to keep pollutants from reaching the bay.
