Under Executive Order 13423, which was signed in 2007, all federal agencies are required to improve water efficiency by 16% by the end of 2015. The U.S. Environmental Protection Agency (EPA) has recognized the U.S. Air Force Academy in Colorado Springs, Colo. as an example of what can be accomplished.
Their facilities have reduced water consumption by 36% since 2000, and were projected to further reduce usage by 41% by the end of 2007. They have implemented a comprehensive set of best management practices such as processing wastewater for reuse for irrigation, using water-efficient landscaping, installing water-efficient bathroom fixtures and educating their members about water efficiency. They are focusing on best management practices that have a simple payback of 10 years or less, and they are active in the local utility's five-year conservation plan.
