I agree that the Cadiz water project in the Mojave Desert requires more study. Because the wise use of water is imperative and our future depends on its conservation, let's look at the numbers.
An acre-foot contains slightly more than 325,000 gallons, so the minimum draw from the desert aquifer of 50,000 acre-feet annually, as the company proposes, is more than 16 billion gallons of water. If that is "enough water every year to serve 100,000 homes," each residence will have the luxury of about 160,000 gallons, enough for many, many leaky toilets, dripping faucets and lush lawns.
Since the average new home uses most of its water outdoors, isn't it time to restrict yard watering so those same 50,000 acre-feet will serve 200,000 homes?
