I'm a water resources engineer. In my experience, this is approximately enough water to supply 15,000 people on an average daily basis.

  Are you saying the average person uses 36,600 gal per year? That seems very high.
  • dastx 7y ago
    I'm not surprised by that number. Showering, flushing, washing dishes uses a lot of water

      Yep. Bathing and flush toilets are huge. It's crazy that potable water is used to flush toilets.

    549mil gallons allowed to use in a year divided by 365 days equals 1,504,109 daily average for google (let's round to 1.5mil). USGS estimates 80-100 gallons per American per day. 1,500,000 google's daily average water use / 100 gallons per American per day = 15,000 Google will use roughly the equivalent of 15,000 Americans worth of daily water. Further math: 100 gallons per American per day x 365 days = 36,500 per person per year. Edit: Had a before coffee typo and added some more math

      Does that number include the water cost of the food we eat? Or is it only direct personal usage?

        "Estimates vary, but, on average, each person uses about 80-100 gallons of water per day, for indoor home uses." https://www.usgs.gov/special-topic/water-science-school/science/water-qa-how-much-water-do-i-use-home-each-day?qt-science_center_objects=0#qt-science_center_objects https://www.usgs.gov/special-topic/water-science-school/scie...
