Chino Basin Recharge Master Plan, Phase I 
The Chino Basin
Recycled Water Groundwater Project is part of the comprehensive
Water Supply Enhancement Program jointly sponsored by the Inland
Empire Utilities Agency (IEUA), Chino Basin Watermaster (CBWM),
Chino Basin Water Conservation District and the San Bernardino County
Flood Control District to improve the quality of local drinking
water wells, enhance water supply reliability, and lower the cost
of water to residents throughout the Chino Basin.
Groundwater Recharge Reports:
Need
for Recharge Project: Reduce dependence on expensive
imported water supplies and provide a local drought-proof supply
of new water for the Chino Basin.
- Statewide
water shortage will continue in California as result of northern
California Bay-Delta issues, Colorado River cutbacks and increased
population. Imported water supplies from northern California are
the most expensive source of water for the Chino Basin and are
increasingly unreliable, especially during droughts.
- Additional
reliable, local water supplies are needed in the Chino Basin to
meet the future needs of our rapidly growing cities and to avoid
future drought shortages.
- High
quality recycled water, produced by IEUA’s recycled water
plants, is released to the Santa Ana River and has been used downstream
for decades to recharge the Orange County Groundwater Basin.
- Chino
Basin community leaders including the Chino Basin Watermaster,
Cucamonga County Water District, Monte Vista Water District, Inland
Empire Utilities Agency and the Cities of Chino, Chino Hills,
Fontana, Ontario, Rancho Cucamonga, and Upland have developed
an integrated water supply plan to meet the future needs of Chino
Basin which includes use of high quality recycled water to recharge
the Chino Groundwater Basin.
- The
Chino Basin Recharge project is needed to meet the requirements
of the court approved Optimum Basin Management Plan and the Chino
Basin Peace Agreement.
- The
Governor’s Water Recycling Task Force (2003) and the California
Bay Delta Authority (2000) recommended that recycled water use
be expended to reduce reliance on imported water from the Delta
and Colorado River.
Chino Basin Facilities Improvement Project – Phase II Following the successful completion of the Chino Basin Facilities Improvement Project, Phase I, additional opportunities to optimize, enhance and increase groundwater recharge were identified. Utilizing matching California Department of Water Resources grant funding, the following improvements were identified to be included as part of the Phase II project:
- Construction of new monitoring wells and lysimeters to monitor recharge operations
- Upgrading the capacity of MWD turnout CB-14 on the Rialto Feeder
- Construction of a new turnout on the Rialto Feeder (CB-20) to provide imported water to 8th Street Basin
- Improvements to conservation berms at four storm water retention basins to increase recharge of storm water
- Improvements to the SCADA system to improve operation of the recharge facilities
- Development of equipment for cleaning the basins without dewatering and drying basins.
