Preface: Everyday millions of people waste water. Here are some water statistics to set the context:
- 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 five 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 seven days, it’s like running the shower constantly for four days or taking more than 800 showers. That’s equivalent to the amount of water needed for the average family to take one 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.

Most of the household water waste happens due to showers. Reducing the use of showers or finding alternate ways to take a bath can drastically reduce the household water wastage.
Problem: Water wastage due to bath showers/bathtubs.
Challenge: Design a bath that uses alternative ways to take a bath. Eliminate/reduce the use of water in baths.
