Best References: Water Efficiency

As local populations and businesses grow, increasing demands for potable water can stress local water supplies, especially during times of drought. Implementing water efficiency programs can help to ensure that water demands will continue to be adequately met in the future, as well as reduce costs for businesses and to the environment. This sector includes documents on water conservation for specific industry sectors such as metal finishing, textiles, and food processing, as well as information on more general water uses such as heating and cooling, kitchens, landscaping, and domestic use.
