Amid Drought, Los Angeles Looks To Upgrade ‘Swamp Coolers’

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 reported Saturday (http://tinyurl.com/zarkqn9) 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 to supplement savings already won when property owners ripped out lawns or installed water-miserly appliances.

OPINION: Dan Morain: Gov. Jerry Brown Gets Ready to Swim Upstream

Jerry Brown is a little like a salmon.

Brown led the campaign to persuade voters to approve the $7.5 billion water bond in 2014. In part because of his exhortations in 2015, in which he derided “nice little green grass getting lots of water every day,” we are tearing out our turf and conserving.

But if 2016 is to be counted as a success, Brown once again must focus on water, specifically the massive California WaterFix project that includes the twin tunnels and restoration of Delta habitat.
