The Los Angeles Reservoir was covered with black and looks like a giant ball pit.
- Earlier this week, the city poured 96 million, black, four-inch plastic balls over the surface of its 175-acre reservoir.
- The first city in the country to use shade balls to preserve its water sources, officials said.
On Monday, Mayor Eric Garcetti released the final 20,000 shade balls into the reservoir on in the city’s effort to conserve water and maintain the reservoir’s water quality.
According to Garcetti, “By reducing evaporation, these shade balls will conserve 300 million gallons of water each year,” he added. “Instead of just evaporating into the sky, that’s 300 million gallons to fight this drought.”
The black plastic balls can last about 10 years before the LA Department of Water and Power will remove, recycle and replace them, the city was able to purchase each plastic balls for 36 cents each, costing the city far less than its initial $300 million estimate to cover the reservoir, according to officials.
Last April, California Gov. Edmund G. Brown Jr. announced a set of mandatory water conservation measures as the state continues to struggle with a prolonged drought that has lasted for more than four years. For the first time in the state’s history, the governor has directed the State Water Resources Control Board to implement mandatory water reductions across California, in an effort to reduce water usage by 25 percent.
“The water needs to be shaded because when sunlight mixes with the bromide and chlorine in Ivanhoe’s water, the carcinogen bromate forms. Bromide is naturally present in groundwater and chlorine is used to kill bacteria, he said, but sunlight is the final ingredient in the potentially harmful mix,” Pankaj Parekh, DWP’s director for water quality compliance said.IMAGE/DAILYNEWS
