How do you fight a drought?
“The Los Angeles Department of Water and Power started a project to fight water evaporation. The final step in this project was to release 96 plastic ‘shade’ balls into a water reservoir until it was entirely covered. These balls protect the water against dust, rain, birds, wildlife and chemical reactions caused by the sun. It also helps keep the water in the reservoir from evaporating.
“By reducing evaporation, these shade balls will conserve 300 million gallons of water each year, instead of just evaporating into the sky. That’s 300 million gallons to fight this drought,” Mayor Eric Garcetti said.
300 million gallons is about enough to provide drinking water for 8,100 people for a full year, so the project is very effective.”
