The largest groundwater recharge plant in the world
With more than 28,000 individual reverse osmosis membranes, the Orange County Water District Ground Water Replenishment System shows how water reuse works at a massive scale.
The Orange County Water District (OCWD) Groundwater Replenishment System (GWRS) is the largest advanced water treatment plant in the world for groundwater recharge. Since it was commissioned, it has produced 445.8 billion gallons of water treated through microfiltration, reverse osmosis and ultraviolet disinfection. That amounts to up to 130 million gallons per day; enough to meet the needs of 1 million people.
Mehul Patel, executive director of operations for the OCWD GWRS, took WaterWorld editors on a tour of the plant to share how it is bolstering Orange County's water supplies through water reuse.
