Orange County Water District’s (OCWD) Groundwater Replenishment System (GWRS) has been recognized as an outstanding groundwater supply project by the National Ground Water Association (NGWA).
The GWRS, a joint project between the OCWD and the Orange County Sanitation District (OC San), is the world’s largest water purification system for indirect potable reuse. It recycles 100% of OC San’s reclaimable wastewater flows and produces 130 million gallons of high-quality water every day. This water is recharged into the Orange County Groundwater Basin, managed by OCWD, and eventually becomes part of the region’s drinking water supplies.
“Thank you, NGWA, for recognizing our dedication to excellence in water supply management,” said OCWD President Cathy Green. “By recycling all local reclaimable wastewater flows, the GWRS maximizes water reuse in the region.”
The GWRS, which went online in 2008, has produced more than 420 billion gallons of water. GWRS water has become a primary source used to refill the groundwater basin and has enabled OCWD’s 19 cities and local water retailers to pump more water from the basin and become more locally sustainable.
The GWRS has been globally recognized for its sound engineering, innovative technology, and public outreach initiatives. To learn more about the GWRS or to book a tour, visit www.ocwd.com/gwrs.
