Total water consumption varies, but according to the Environmental Protection Agency, the average family of four can consume up to 400 gallons of water per day. The American Water Works Association, puts its estimate closer to 280 gallons per day.

The Bathroom

According to both the EPA and the AWWA, the bathroom is the leading user of water. The AWWA estimates approximately 50 per cent of daily water consumption is from the bathroom. The toilet is the highest user at 26.7 per cent, or 18.5 gallons per person per day.

Clothes Washer

The next largest culprits are washing machines. At 15 gallons per person per day, clothes washers use 21.7 per cent of the total daily water consumed daily per person. They are second only to the toilet, but consume more than showers, baths and faucets.

Leaky Faucets

Faucets in general are a leading consumer of water, but leaks alone account for approximately 13.7 per cent of daily water usage, according to the AWWA. Fixing the leaks can reduce water use dramatically.
