As of May 26, 2020, IEUA has resumed its free Regional Water-Use Efficiency Programs. If you would like any information on water saving programs or rebates, please contact Lisa Morgan-Perales at lperales@ieua.orgor contact the IEUA Water Use Efficiency Hotline at 909-993-1952.

The Inland Empire Utilities Agency (IEUA) was formed in 1950 to supply imported drinking water to the Chino Basin. Originally named the Chino Basin Municipal Water District, IEUA has been a leader in water supply planning and programs to protect the region’s vital water supplies for over fifty years.

Smart water planning starts with water conservation. Every gallon of water saved within the Chino Basin translates into reduced demand for expensive imported water supplies. By being more efficient, our community will increase the reliability of our existing water supplies and reduce the cost of imported water purchases. IEUA’s goal is to save over 25,000 acre-feet of water over the next twenty years through conservation – that’s about 7% of our area’s current water use.

To achieve this water conservation goal, IEUA is working closely with the following local retail water agencies: the cities of Chino, Chino Hills, Ontario, and Upland, Cucamonga Valley Water District, Monte Vista Water District, Fontana Water Company and the San Antonio Water Company.

Here’s How You Can Help Conserve Water – And Save Money on Your Water Bills

In partnership with the Metropolitan Water District, the State of California and the local retail water agencies of the Chino Basin, IEUA is offering special conservation rebates that will reward residential customers for using water efficient toilets, clothes washers and other appliances and reward business customers for using water brooms and installing other water efficient appliances.

In addition, IEUA is undertaking a native landscaping initiative to promote the use of native and other water efficient plants as well as the installation of water efficient irrigation systems. Look for our special conservation programs in the schools, too, including waterwise gardens using native and California friendly plants and Water Conservation based stage productions from the National Theater for Children.

In response to the Governor’s Declaration of a Statewide drought and the issuance of a “Water Supply Alert” by the Metropolitan Water District on imported water supplies, IEUA member agencies have implemented local water conservation ordinances that include mandatory water-use restrictions.
