Las Vegas and the Future of Water Usage in the U.S.
A quick article on how Las Vegas has become the most water smart city in the country:
It's illegal now to have a front lawn in any new home in Las Vegas. The water authority will pay people who already have lawns to take them out--$40,000 an acre-- and replace them with native desert landscaping. They pay golf courses to do the same thing. It is illegal to let your sprinkler spray water on a sidewalk or street, and Las Vegas specifies the kind of hose nozzle you can use to wash your car (trigger style, so it doesn't simply pour water out when you're not using it).
And a determined recycling effort has produced pioneering results: the Las Vegas metro area now collects, cleans, and recycles to Lake Mead 94 percent of all water that hits a drain anywhere in the city. Essentially, the only water that isn't directly recycled back to the source is the water used outdoors.
