Benefits of Water Efficiency

-A A +A

Save Water, Save Money
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 $132 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 $17 billion dollars per year! Also, when we use water more efficiently, we reduce the need for costly water supply infrastructure investments and new wastewater treatment facilities.

Save Water, Save Energy
It takes a considerable amount of energy to deliver and treat the water you use everyday. American public water supply and treatment facilities consume about 50 billion kilowatt-hours (kWh) per year—enough electricity to power more than 4.5 million homes for an entire year. For example, letting your faucet run for five minutes uses about as much energy as letting a 60-watt light bulb run for 14 hours.
By reducing household water use you can not only help reduce the energy required to supply and treat public water supplies but also can help address climate change. In fact:

  • If 1 out of every 100 American homes retrofitted with water-efficient fixtures, we could save about 100 million kWh of electricity per year—avoiding 75,000 tons of greenhouse gas emissions. That is equivalent to removing nearly 15,000 automobiles from the road for one year!
  • If 1 percent of American homes replaced an older toilet with a high-efficiency toilet (HET), the country would save more than 38 million kWh of electricity—enough to supply more than 43,000 households electricity for one month.

Water Efficiency, Human Health and the Environment
Depleting reservoirs and groundwater aquifers can put water supplies, human health, and the environment at serious risk. Lower water levels can lead to higher concentrations of natural contaminants, such as radon and arsenic, or human pollutants, such as agricultural and chemical wastes. Using water more efficiently helps maintain supplies at safe levels, protecting human health and the environment.
