The Westside Project is currently in preliminary design, and is preparing to initiate environmental review. A revised Notice of Preparation for environmental review will be issued in 2013.
Highly-treated recycled water would be delivered to a variety of customers through a system of pipelines, pump stations, storage tanks and reservoirs. The system would bring recycled water from the recycled water treatment facility to Golden Gate Park, Lincoln Park Golf Course, and the Presidio Golf Course to be used for irrigation. Additionally, recycled water would be used for toilet flushing at the California Academy of Sciences in Golden Gate Park.
Treatment Plant and Process
A new Recycled Water Treatment Plant is proposed to be constructed at the SFPUC’s existing Oceanside Water Pollution Control Plant (WPCP). Secondary effluent from the Oceanside WPCP would be treated further with membrane filtration, reverse osmosis, ultraviolet (UV) light disinfection, to produce high-quality recycled water. The project would produce and deliver up to 2 million gallons per day (mgd) on average, with peak deliveries of up to 4 mgd during the summertime of recycled water that is suitable for all recycled water uses approved by the State of California.
Distribution pipelines would be mostly under City streets and in limited sections of Golden Gate Park. Specific alignments for proposed recycled water pipelines are being developed.
