The U.S. Environmental Protection Agency named The Home Depot a 2015 WaterSense Sustained Excellence award winner. The Home Depot, the world's largest home improvement retailer, was honored for the third consecutive year for its commitment to water efficiency and education as it continues to help build consumer awareness about WaterSense-certified products in stores and online.

By offering rebates and consumer education through in-store and online channels about WaterSense products and programs, EPA partners like The Home Depot helped consumers save 346 billion gallons of water in 2014 alone.

"With drought being such a prevalent issue in the western half of our nation, educating our associates and customers about water conservation is the right thing to do," says Ron Jarvis, vice president of environmental for The Home Depot. "We plan to continue helping our customers save water and money as we continue to expand our WaterSense offerings and education."

With the help of The Home Depot, WaterSense also has helped reduce the amount of energy needed to heat, pump and treat water by 146 billion kilowatt hours, enough energy to supply a year's worth of power to more than 13.3 million homes.
