The Average Consumption of Water for a Human

Sometimes it's difficult to make the decision to help the environment, especially when it's so hard figuring out where to start. Before reducing water consumption, first a person has to know the average consumption of water for a human.

  1. Considerations

    • One problem with calculating the average consumption of water for a human is deciding what counts as consumption. Assuming we mean all forms of water usage such as personal hygiene as well as drinking water, this figure can vary wildly from individual to individual.

    Daily

    • The average citizen of the United States uses 69 gallons of water every day. This figure includes hygiene such as toilet flushing, washing dishes and other forms of running water. For comparison, Australia's daily water consumption is around 130 gallons a day.

    Lifetime

    • Based on how much a person must drink -- just over 2 quarts of water a day -- the lifetime average for water consumption of a human is difficult to estimate. The average, however, is somewhere around 19,812 gallons in a lifetime.
