The results are based on average water use and not measured water use for one week. We figured the results for each third grade class and for all the classes together. And then we multiplied the weekly averages by 52 to see how much water might be used in one year. The table below shows the results for April 1421, 2008.

So 115 third graders would use about 4,295,356 gallons of water each year. How much is 4,295,356 gallons? An Olympic swimming pool holds about 500,000 gallons of water. Fill the pool and empty it 8 times and then fill it more than half way full again and that would use the same amount of water.
