From Sewage, Added Water for Drinking
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.
The process, called by proponents “indirect potable water reuse” and “
toilet to tap” by the wary, is getting a close look in several cities.
