infrastructure by providing long-term, low-cost supplemental
loans for regionally and nationally significant projects.
GROUNDWATER REPLENISHMENT SYSTEM FINAL EXPANSION
BORROWER: Orange County Water District
LOCATION: Fountain Valley, California
WIFIA LOAN AMOUNT: $135 million
TOTAL WIFIA PROJECT COSTS: $282 million
POPULATION SERVED BY SYSTEM: 2.5 million people
NUMBER OF JOBS CREATED: 700 jobs
PROJECT DESCRIPTION
The Orange County Water District will expand its existing 100 million gallons per day (MGD)
Groundwater Replenishment System to produce an additional 30 MGD drought-proof drinking
water supply for its service area. The project will replenish the Orange County Groundwater
Basin and reduce the need for imported water. Treated wastewater from the Orange County
Sanitation District (OCSD) Plant 2 will be purified using a three-step process that produces high
quality water and then stored in the groundwater basin. The final expansion project will include
expanding the existing treatment facility, constructing a pump station, rehabilitating pipelines,
and reconfiguring the treatment process.
PROJECT BENEFITS
•	Reduces approximately 40 MGD of secondary effluent from being discharged into the ocean.
•	Increases the replenishment of the groundwater basin.
•	Provides an additional 31,000 acre-feet per year drought-proof water supply at a lower cost
than imported water.
•	Upon completion, the GWRS will be recyling all of OCSD's reclaimable wastewater and will
produce enough water for more than 1 million people.
•	Saves the Orange County Water District up to $16 million from financing with a WIFIA loan
compared to a bond issuance.
