Where Does Your Water Come From?

Have you ever wondered where your water comes from when you turn on the tap?

Ontario’s water supply sources are comprised of imported surface water, groundwater, and recycled water.

-Locally treated State Water Project water is purchased from the Water Facilities Authority, which purchases it from the Inland Empire Utilities Agency (IEUA) as the regional wholesaler in our area. 

-A portion of Ontario's surface water is also supplied by the San Antonio Water Company (SAWCo).

-IEUA is also the local wastewater treatment agency and OMUC purchases recycled water from IEUA for direct use in agriculture and residential/commercial irrigation. 

-Groundwater supplies are produced by City-owned groundwater wells and purchased from the Chino Basin Desalter Authority. Currently, the majority of Ontario's water demands are met by local groundwater and recycled water supplies.
