The U.S. Environmental Protection Agency’s (EPA’s) WaterSense program labels weather-based irrigation controllers (WBICs) that have been certified by a third party to meet efficiency and performance criteria detailed in the WaterSense specification. WaterSense labeled controllers must be able to adequately meet the watering needs of a landscape without overwatering.You may need a PDF reader to view some of the files on this page.
