On April 14, Orange County, Calif.’s Water District (OCWD) and Sanitation District (OC San) announced that together, they had accomplished something that has never been done anywhere else, ever. They are purifying and recycling 100 percent of the county’s reclaimable wastewater. The county’s Groundwater Replenishment System (GWRS), operational and expanding continuously since 2008, is the largest indirect potable water reuse facility in the world…. The GWRS now provides 130 million gallons of water a day, enough to meet the daily needs of a million residents.
