Statistics & Facts
Why Save Water?
- Water is a finite resourceeven though about 70 percent of the Earth's surface is covered by water, less than 1 percent is available for human use.
- Forty out of 50 state water managers expect water shortages under average conditions in some portion of their states over the next decade.
- Each American uses an average of 100 gallons of water a day at home.
- We can all use 30 percent less water by installing water-efficient fixtures and appliances.
- The average household spends as much as $500 per year on their water and sewer bill and can save about $170 per year by installing water-efficient fixtures and appliances.

WaterSense & Water Savings
- WaterSense labels products that are 20 percent more water-efficient and perform as well as or better than standard models.
- WaterSense labeled faucets—or aerators that can be installed on existing bathroom faucets—are about 30 percent more efficient than standard faucets while still providing sufficient flow.
- WaterSense labeled toilets use 20 percent less water per flush but perform as well as or better than today's standard toilets and older toilets that use much more water.
- The WaterSense label is now found on more than 1,600 models of showerheads, 1,900 models of tank-type toilets, 6,800 models of faucet or faucet accessory models, and 150 models of weather–based irrigation controllers that are independently certified to meet EPA's criteria for both water efficiency and performance.
- To design, service, or audit your in-ground landscape irrigation system, look for an irrigation professional certified by a WaterSense labeled program.

Facts & Statistics
- Approximately 5 to 10 percent of American homes have water leaks that drip away 90 gallons a day or more! Many of these leaks reside in old fixtures, such as leaky toilets and faucets. In fact, water lost by these leaky residences could be reduced by more than 30,000 gallons if new, efficient fixtures were installed. If the 5 percent of American homes that leak the most corrected those leaksit could save more than 177 billion gallons of water annually!
- Using WaterSense labeled faucets or faucet accessories could reduce a household's faucet water use by more than 500 gallons annuallythat's enough water to do 14 loads of laundry.
- WaterSense labeled faucets and faucet accessories can reduce excessive flow volumes by more than 30 percent without sacrificing performance.
- If one in every 10 homes in the United States were to install WaterSense labeled faucets or faucet accessories in their bathrooms, it could save 6 billion gallons of water, and more than $50 million in the energy costs to supply, heat, and treat that water.
- If all inefficient toilets in U.S. homes were converted to WaterSense labeled models, we could save more than 640 billion gallons of water per year—the equivalent to 15 days of flow over Niagara Falls.
- If homeowners with irrigation systems use a certified irrigation professional to perform regular maintenance, they can reduce irrigation water use by 15 percent or nearly 8,800 gallons of water annually. That's the equal to the amount of water used to take 500 showers.
