Average Water Use

While use can vary, the average person uses 70 to 90 gallons of water per day indoors. Add another 70 gallons per day for your outdoor water use during the warmest months.

Gallons Per Use


It may be difficult to imagine how all that water is used, but consider this:
  • Brushing your teeth with the water running can use 10 gallons of water
  • A 5-minute shower with a regular shower head uses 30 gallons
  • Flushing the toilet uses 1.5 to 5 gallons per flush depending upon the efficiency of the fixture
  • Washing laundry uses 45 gallons per load
  • Running the Dishwasher uses 12 gallons per load
  • Hand washing dishes uses 20 gallons
  • Cooking uses 5 to 10 gallons per person per day outdoor
  • Watering uses 5 to 10 gallons per minute
