Recycled Water

To meet future water demands while reducing our dependence on imported water, the City of San Diego has built the North City Water Reclamation Plant and the South Bay Water Reclamation Plant. These plants treat wastewater to a level that is approved for irrigation, manufacturing and other non-drinking, or non-potable purposes. Recycled water gives San Diego a dependable, year-round and locally controlled water resource.
