The Federal Energy Management Program (FEMP) provides agencies with guidance and direction on how to increase water efficiency and reduce water use in federal buildings and campuses.

The key water-related requirements are contained in the Energy Independence and Security Act of 2007 and the Energy Policy Act of 2005. Learn more about water efficiency requirements.

Agencies are also required to include water-efficient elements in new construction per the Guiding Principles for Sustainable Federal Buildings.
