Federal agencies are required to purchase U.S. Environmental Protection Agency (EPA) WaterSense-labeled products where applicable. Faucets, pre-rinse spray valves, showerheads, toilets, and urinals are covered under the WaterSense program. The Federal Energy Management Program (FEMP) discontinued its product designations and purchasing specifications for these products to avoid duplicating efforts and to simplify the federal procurement process. However, FEMP continues to offer technical assistance on water efficiency. Learn about water use reduction.
Plumbing codes and standards require a flow rate of 0.5 gallons per minute (gpm) for public lavatory faucets and 0.25 gallons per cycle (gpc) for metered faucets. There are currently few products on the market with flow rates lower than these requirements. In addition, there is no documentation that lavatory faucets with flow rates lower than 0.5 gpm and 0.25 gpc perform in a satisfactory manner.
FEMP continues to monitor market and research activity for commercial faucets and, if warranted, will reissue performance requirements and a purchasing specification for this product type. For more information, see Best Management Practice (BMP) #7: Faucets and Showerheads the Energy Cost Calculator for Faucets and Showerheads, and EPA WaterSense.
