FOUNTAIN VALLEY, Calif. — It used to be so final: flush the toilet, and waste be gone.I knew there was a good reason that I rely mainly on Diet Coke for hydration. Wonder where they get their water??
But on Nov. 30, for millions of people here in Orange County, pulling the lever will be the start of a long, intense process to purify the sewage into drinking water — after a hard scrubbing with filters, screens, chemicals and ultraviolet light and the passage of time underground.
On that Friday, the Orange County Water District will turn on what industry experts say is the world’s largest plant devoted to purifying sewer water to increase drinking water supplies. They and others hope it serves as a model for authorities worldwide facing persistent drought, predicted water shortages and projected growth.
