Where does the City of Ontario get its water from?
Ontario’s water supply sources are comprised of imported surface water, groundwater, and recycled water. The City purchases locally treated State Water Project imported water directly from the Water Facilities Authority (WFA), which purchases it from the Inland Empire Utilities Agency (IEUA). IEUA is the region's imported water wholesaler, supplied by the Metropolitan Water District (MWD), and the local wastewater treatment agency. A portion of Ontario's surface water is also supplied by the San Antonio Water Company (SAWCo).
Groundwater supplies are produced by City-owned groundwater wells and purchased from the Chino Basin Desalter Authority (CDA). The City purchases recycled water from IEUA for direct use in agricultural and residential/commercial irrigation as well as groundwater recharge.
The City of Ontario has invested significantly in local groundwater and recycled water infrastructure to become less dependent on imported water from MWD via IEUA. Currently, the majority of Ontario's water demands are met by local groundwater and recycled water supplies.
