Productivity and Efficiency

According to the U.S. Environmental Protection Agency, water efficiency is the smart use of our water resources through water-saving technologies and simple steps. Using water efficiently will help ensure reliable water supplies today and for future generations. Topics addressed in this theme provide insights, lessons, and guidance on how diverse stakeholders are working to improve water management and reduce water use.
