Amid drought, Los Angeles looks to upgrade 'swamp coolers'

LOS ANGELES (AP) - Old-school cooling systems on the roofs of larger Los Angeles buildings may be wasting billions of gallons of water each year.

The Los Angeles Times reports Saturday that some of these "swamp coolers" are so inefficient they can use as much water as all the bathrooms, drinking fountains and kitchens in the buildings below.

As California's drought persists, officials are looking everywhere for water savings.

Los Angeles Mayor Eric Garcetti last month encouraged building owners to upgrade cooling towers. The hope is to save 100 million gallons of water annually.

That's still a drop in the bucket.

David Hodgins of the Los Angeles Better Building Campaign estimates that, across all Los Angeles County, cooling towers waste more than 2.5 billion gallons each year. That's enough to serve 15,000 households.
