Water scarcity and purity are local and worldwide challenges.  The EPA has been setting increasingly higher standards of water efficiency for plumbing fixtures for two decades,.  WaterSense is managed by the EPA program and is the nation's only water efficiency certification program.  Other programs, such as LEED, set benchmarks for selected products, but do not provide product certifications.  For more information about WaterSense, click here.  For detailed water-efficiency requirements, see the Alliance for Water Efficiency's comparison table created in August 2010 from the most current standards here .
