The largest water district in the country, the Metropolitan Water District of Southern California, is discussing development of a recycled water program with the Los Angeles County sanitation districts. And not just any recycled water program, one of the largest in the world.

According to the Los Angeles Times, in a committee meeting earlier this week, a plan was presented “to purify and reuse as much as 168,000 acre-feet of water a year – enough to serve about twice that number of households for a year”.

To put this plan into action, a treatment plant and delivery facilities would need to be built and that could cost about $1 billion.
