The Groundwater Replenishment System Final Expansion (GWRSFE) project will increase treatment capacity from 100 to 130 million gallons per day (MGD); enough water for 1 million people!
In order to produce 130 MGD, additional treated wastewater from the Orange County Sanitation District (OCSD) is required. This additional water will come from OCSD’s Treatment Plant 2, which is located in the city of Huntington Beach approximately 3.5 miles south of the GWRS. The GWRSFE project will include expanding GWRS treatment facilities, constructing new conveyance facilities at OCSD Plant 2 and rehabilitating an existing pipeline between OCSD Plant 2 and the GWRS.

The estimated construction cost of the GWRS Final Expansion Project is $310 million. (View the construction bid results here.) In August 2018, OCWD's Board of Directors executed a loan agreement with the US EPA for a low interest rate WIFIA loan in the amount of $135 million. OCSD/OCWD has received a USBR Title XVI grant for the P2 Headworks Modification Project, has applied for Prop 1 grants from the IRWM grant program managed by the California Department of Water Resources, and our application for a State Revolving Fund Loan through the State Water Resources Control Board has been deemed complete with an intent for the remaining project costs to be funded through this loan.
