The Enhanced Recharge Project (ERP) consists of improvements to existing diversion and recharge facilities owned and operated by the San Bernardino Valley Water Conservation District (SBVWCD). Improvements included adding a debris removal system and rubber dam gate at the intake and constructing a new sedimentation basin, canal, pipeline, and recharge basins to increase the amount of stormwater that can be captured and recharged from the Santa Ana River just downstream from the Seven Oaks Dam. The project is capable of diverting and recharging up to 80,000 acre-feet of water in a single year and 500 cubic feet per second instantaneous flow (once all phases are complete).

Phase 1 is located outside of the Upper Santa Ana Wash Land Management and Habitat Conservation Plan (WashPlan) intake improvements, sedimentation basin, and the Plunge Pool Pipeline (PPP).  It was completed in November 2018.

The District will construct additional groundwater recharge ponds over the next couple of years to increase the capture of stormwater runoff on the Santa Ana River for groundwater recharge purposes.
