Current Use of Recycled Water in Our Service Area
Presently, IEUA wholesales disinfected tertiary recycled water to the City of Chino, City of Chino Hills, and the City of Ontario. With the exception of Reliant Energy located in Etiwanda, most of the current recycled water users are located in IEUA’s Southern Service Area. Plans are underway to expand the recycled water system to include the Northern Service Area via recycled water pipelines, pump stations, and satellite plants.
RWRP-1 Recycled Water Uses
Plant effluent is currently used for irrigation of the Whispering Lakes Golf Course, El Prado Golf Course, and Westwind Park. It also supplies water to the Prado Regional Park Lake in southwestern San Bernardino County, the excess flow is being discharged to the Cucamonga Creek Flood Control channel and into the Santa Ana River.
Recycled water from the RWRP-1 Facility is also currently used to recharge the Chino Basin aquifer via the Ely Basin No. 3 at the rate of 500 AFY. The quantity of recycled water recharged in the Basin is scheduled to increase to 2,300 AFY in the future.
RWRP-2 Recycled Water Uses
The RWRP-2 tertiary effluent is currently released to Chino Creek.
RWRP-4 Recycled Water Uses
The RWRP-4 tertiary effluent is combined with the RP-1 effluent and thus is used for irrigation of the El Prado Golf Course, and also supplies water to the Prado Regional Park Lake in southwestern San Bernardino County, with excess being discharged to the Cucamonga Creek Flood Control channel and onto the Santa Ana River. It will soon be used as cooling water for Reliant's Etiwanda generating station.
CCWRF Recycled Water Uses
Plant effluent is delivered to the IEUA “southern” recycled water distribution system that supplies water to the City of Chino and the City of Chino Hills. The City of Chino has 24 customers ranging from industries, to City parks and small businesses. The City of Chino Hills has larger users, i.e., golf courses, housing associations and much of the City’s greenbelt area…parkway medians and curb areas.
RWRP-5 Recycled Water Uses
RWRP-5 currently under construction. The recycled water from this plant will be available for unrestricted recreational use, such as boating, fishing, and swimming. Any excess and chlorinated/dechlorinated effluent will be released to Chino Creek.
