Groundwater Recharge

IEUA, Chino Basin Watermaster, Chino Basin Water Conservation District, and the San Bernardino County Flood Control District jointly sponsor the Chino Basin Recycled Water Groundwater Recharge Program. This program was put in place to enhance water supply reliability and to enhance drinking water quality throughout the greater Chino Basin.

As part of the recycled water expansion, IEUA has enhanced the capabilities of the Groundwater Recharge Program to help replenish the area’s underground aquifers. These recharge sites improve the reliability of the local groundwater supply for a growing population.

Located throughout IEUA’s service area are 19 recharge sites designed to capture runoff from storms, imported water from the State Water Project and high-quality recycled water from IEUA’s distribution system.

In FY 2018/19, IEUA recharged 12,861 AF of stormwater/local runoff; and delivered 6,787 AF of imported water and 11,543 AF of recycled water.

Recycled water direct usage was 16,803 AFY.
