On the west side of San Francisco, we are aiming to save up to 2 million gallons per day (mgd) on average of drinking water that is currently used for non-drinking purposes such as irrigation and lake fill. Recycled water will be delivered for these uses through a system of pipelines, pump stations, storage tanks and reservoirs. The system will bring recycled water from the recycled water treatment facility to Golden Gate Park, Lincoln Park Golf Course, the Presidio Golf Course and other landscaped areas for irrigation.
Treatment Facility and Process
A new Recycled Water Treatment Facility is being constructed within the limits of our existing Oceanside Water Pollution Control Plant (WPCP). Secondary effluent from the Oceanside WPCP will undergo an advanced treatment process using membrane filtration, reverse osmosis, and ultraviolet light disinfection to produce recycled water at a level that will exceed state of California standards. The project will produce and deliver up to 2 mgd on average of recycled water, 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.
Almost 8 miles of new recycled water pipelines have been constructed mostly under City streets. These pipelines will bring recycled water from the newly constructed treatment facility to customers. Construction has also begun on an underground recycled water reservoir, and above-ground recycled water pump station in Golden Gate Park that will pump recycled water to Lincoln Park and the Presidio.
