Statistics and Facts
Why Save Water?
- According to a 2014 Government Accountability Report, 40 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 82 gallons of water a day at home (USGS, Estimated Use of Water in the United States in 2015).
- We can all use at least 20 percent less water by installing water-efficient fixtures and appliances.
- The average family spends more than $1,000 per year in water costs, but can save more than $380 annually from retrofitting with WaterSense labeled fixtures and ENERGY STAR certified appliances.
WaterSense & Water Savings
- WaterSense labels products that are 20 percent more water-efficient and perform as well as or better than standard models.
- The average family can save 13,000 gallons of water and $130 in water costs per year by replacing all old, inefficient toilets in their home with WaterSense labeled models.
- Replacing old, inefficient bathroom faucets and aerators with WaterSense labeled models can save the average family $250 in water and electricity costs over the faucets' lifetime.
- Replacing showerheads with WaterSense labeled models can reduce the average family's water and electricity costs by $70 and can save the average family more than 2,700 gallons of water per year, equal to the amount of water needed to wash 88 loads of laundry.
- Giving a home's main bathroom a high-efficiency makeover by installing a WaterSense labeled toilet, showerhead, and faucet aerator can pay for itself in as little as 1 year.
- Replacing a clock-based controller with a WaterSense labeled irrigation controller can reduce an average home's irrigation water use by up to 30 percent and can save an average home up to 15,000 gallons of water annually.
- The average family can waste 180 gallons per week, or 9,400 gallons of water annually, from household leaks. That's equivalent to the amount of water needed to wash more than 300 loads of laundry.
- Household leaks can waste approximately nearly 900 billion gallons of water annually nationwide. That's equal to the annual household water use of nearly 11 million homes.
- Running the dishwasher only when it's full can eliminate one load of dishes per week and save the average family nearly 320 gallons of water annually.
- Turning off the tap while brushing your teeth can save 8 gallons of water per day and, while shaving, can save 10 gallons of water per shave. Assuming you brush your teeth twice daily and shave 5 times per week, you could save nearly 5,700 gallons per year.
- Letting your faucet run for five minutes while washing dishes can waste 10 gallons of water and uses enough energy to power a 60-watt light bulb for 18 hours.
- Outdoor water use accounts for more than 30 percent of total household water use, on average, but can be as much as 60 percent of total household water use in arid regions.
- If the average sized lawn in the United States is watered for 20 minutes every day for 7 days, it’s like running the shower constantly for 4 days or taking more than 800 showers. That's equivalent to the amount of water needed for the average family to take 1 year's worth of showers.
- As much as 50 percent of the water we use outdoors is lost due to wind, evaporation, and runoff caused by inefficient irrigation methods and systems. A household with an automatic landscape irrigation system that isn't properly maintained and operated can waste up to 25,000 gallons of water annually.
- When hiring a professional to install or audit your landscape irrigation system, be sure he or she is certified by a WaterSense labeled irrigation program. If the system is well managed, a household's irrigation water use can be reduced by 15 percent, or nearly 7,600 gallons of water, annually. That's the amount of water needed to take 480 showers.
