The four jurisdictions that own SBSA . . . West Bay Sanitary District and the cities of Belmont, Redwood City, and San Carlos . . . each appoint a member of their council or board to the SBSA Commission.
Through regulations and outreach programs, SBSA works with businesses in the service area to facilitate the convenient discharge of wastewater that is acceptable for treatment at the SBSA facility.
Purified wastewater is discharged through a 66 inch diameter pipeline to the submarine outfall diffuser about a mile offshore. The diffuser is located at a depth of 45 feet in the main shipping channel approximately 2 miles south of the San Mateo Bridge.
