The average household spends as much as $500 per year on its water and sewer bill. By making just a few simple changes to use water more efficiently, you could save about $170 per year. If all U.S. households installed water-efficient appliances, the country would save more than 3 trillion gallons of water and more than $18 billion dollars per year!
When we use water more efficiently, we reduce the need for costly water supply infrastructure investments and wastewater treatment facilities. It takes a considerable amount of energy to deliver and treat the water we use everyday. American public water supply and treatment facilities consume about 56 billion kilowatt-hours (kWh) annually—enough electricity to power more than 5 million homes for an entire year.
Of the estimated 29 billion gallons of water used daily by households in the United States, nearly 7 billion gallons - 30% - is devoted to outdoor water use. How often and how much you water really does matter.
