East Bay Dischargers Authority

What East Bay Dischargers Authority does

East Bay Dischargers Authority (EBDA) is a Joint Powers Authority established on February 15, 1974 by five East Bay municipal governments — the City of San Leandro, Oro Loma Sanitary District, Castro Valley Sanitary District, City of Hayward, and Union Sanitary District — to consolidate regional wastewater disposal. The agency operates an integrated transmission and discharge system comprising 11.5 miles of large-diameter pipelines (48" to 96"), four pump stations, a dechlorination facility, and a seven-mile outfall that delivers treated effluent to the deepest part of San Francisco Bay. On average, 60 million gallons per day flow through the system, peaking at 189 MGD during winter storms, serving approximately 1 million East Bay residents and thousands of businesses. EBDA also provides contract service to the Livermore-Amador Valley Water Management Agency, extending service to Pleasanton, Livermore, and Dublin.

The agency operates under NPDES Permit R2-2022-0023 issued by the San Francisco Bay Regional Water Quality Control Board. Revenue is generated exclusively through proportional contributions from member and contract agencies based on the volume of wastewater each sends through the system — there is no commercial pricing model. EBDA is governed by a Commission of member-agency appointees and supported by a lean staff (1-10 employees) with Jacqueline Zipkin, P.E. as General Manager. Beyond core conveyance, EBDA is pursuing adjacent initiatives including the Cargill brine discharge partnership (EIR certified June 2023), the First Mile Horizontal Levee shoreline resilience project, Hayward Shoreline adaptation work via HASPA, and EPA Water Quality Improvement Fund grants routed through the San Francisco Estuary Partnership.
