Drought Proofing Orange County: World’s Largest Water Purification Plant Expands to 100 MGD

WHAT: Groundwater Replenishment System Initial Expansion Dedication

In 2008, history was made when the Orange County Water District (OCWD) brought 70 million gallons a day (MGD) of new high-quality water to the region through its world renowned Groundwater Replenishment System (GWRS). As seen on 60 Minutes, the GWRS has been hailed as a solution to drought and a global model for local water reliability.

Following nearly eight years of successful operation, OCWD made the world’s largest project even bigger. This month, a 30-MGD expansion of the GWRS was put into operation and officials will preside over a dedication event to celebrate this accomplishment during one of California’s most severe droughts on record.

With the completion of the expansion, OCWD is bringing 100 MGD of reliable water to Orange County. Total water production of the GWRS is now 103,000 acre-feet per year or enough water for 850,000 people. But, OCWD is not stopping here. It is exploring the feasibility of a final GWRS expansion and will continue to invest in projects that create long-term water reliability for the region.

The GWRS is a joint project of OCWD and the Orange County Sanitation District. It takes highly treated wastewater and purifies it through a three-step process of microfiltration, reverse osmosis and ultraviolet light with hydrogen peroxide, resulting in near-distilled quality water. This is the highest quality water in the region!

WHEN:  9 a.m. – 10:30 a.m. Friday, June 26, 2015
