Average Family Water Usage

I shared our family's average monthly electric usage in this post, and now I would like to share our water usage.  I had seen an article stating the average family of 4 spends $80 a month on their water bill and I was shocked.  We rarely go above $25 a month on our water bill!  I had to find out how many gallons we were using a month and then it became a little complicated.

On your water bill, it will tell you how much water you used that month but sometimes it is in cubic feet.  Ours is in cubic feet and I had no idea how to convert that to gallons, so the search began for answers.  I found this conversion information on the EPA website: http://www.epa.gov/watersense/our_water/understanding_your_bill.html  That told me that one CCF (Centum Cubic Feet) is equal to 748 gallons.  One CCF is one hundred cubic feet.  Our average water usage for a month is 700 cubic feet and that is equal to 7 CCFs.  I now had the formula to find out how many gallons - 7 CCFs x 748 gallons = 5,236 galllons.

Our Family's Average Water Usage
700 cubic feet = 5,200 gallons a month

The average family of 4 has an average water usage of 1600-2000 cubic feet a month, which is about 12,000-15,000 gallons per month. We are using less than HALF the amount of the average family and that explains why our bill is $20-$25 a month.  The average for one person is 100 gallons a day or 3,000 gallons a month.  So at 3,000 gallons per person, you can estimate easily for your average depending on your family size.  For example, a family of 6 would use an average of 18,000 gallons of water a month.

Who knew we were such big water savers?  I don't really have any tips because I don't know what we are doing that others aren't.  I do know that we are mindful of water usage in that we don't let water run for no reason.  Here is a chart of the average number of gallons certain things in your home use that may be helpful in cutting costs and the website also provides some links to calculators:  http://water.usgs.gov/edu/qa-home-percapita.html
