The Project will construct, adjacent to the existing Antioch Water Treatment Plant A, a brackish water desalination facility capable of producing up to 6 mgd of finished water. The treatment facility construction will include storage tanks, pumps, an electrical substation, and supporting piping, equipment, and appurtenances. In addition, a new San Joaquin River intake pump station and fish screen will be constructed at the existing intake location and the existing intake pump station and fish screen removed. The exi sting intake pipeline will be modified to enable river water to flow directly to Treatment Plant A and the new desalination facility. A new brine line will be constructed to convey brine from the desalination facility to the existing Delta Diablo Wastewater Treatment Plant outfall where it will be discharged to New York Slough with the treated wastewater effluent through the existing Delta Diablo outflow.

The objectives of the project are to improve water supply reliability and operational flexibility while improving water quality and ecosystem conditions, especially during droughts and future changes in Delta water management.
