3.5 rating based on 42 ratings

The Water Calculator is a tool that estimates household water use and compares homes to both typical and efficient households in your zip/postal code. It also estimates your carbon footprint from hot water consumption and helps identify specific strategies for reducing water consumption. A family of four should use about 320-400 gallons of water per day, with a 4-bedroom house using around 60 gallons per person per day. In the US, an average person uses 80-100 gallons of water per day for indoor home uses. The largest use of household water is to bathe, cook, and wash.

The Water Calculator uses mathematical models and equations developed by Aquacraft to estimate indoor and outdoor water use. It quickly estimates how much water your household uses and compares it to a similar average and a highly efficient home. It also shows you where to begin your home water conservation efforts.

The average American family of four uses 400 gallons of water per day, with approximately 70% of that water used indoors. In general, we use 50 to 100 gallons per person per day in our homes (200 to 400 gallons per day for a family of four). The average person uses around 142 liters of water daily, which means a family of four will use around 500 liters of water every single day.

To reduce water consumption, consider the following tips:

  1. Use 8 glasses of 8oz cups of water per gallon.
  2. Use 15 gallons of water per person per day for a washing machine.
  3. Consider adding a pool or other water-efficient features to your home.
  4. Use less water than you need for your lawn watering or pool.
  5. Consider using a water-efficient showerhead or faucet instead of a traditional showerhead.
