EPA WaterSense is a program sponsored by the U.S. Environmental Protection Agency (EPA), designed to encourage water efficiency in the United States through the use of a special label on consumer products.[1] The goal of this program is to protect the future of the U.S. water supply. WaterSense maintains partnerships with key utility, manufacturer and retail partners across the United States. WaterSense is voluntary, rather than a regulatory program. The EPA develops specifications for water-efficient products – low-flow fixtures – through a public process. If a manufacturer makes a product that meets those specifications, the product is eligible for third-party testing to ensure the stated efficiency and performance criteria have been met. If the product passes the test, the manufacturer is rewarded with the right to put the WaterSense label on that product
