Water Use Calculators

One good early step in thinking about the opportunities you have to use water more efficiently in your own life is to find out how much water you're using now. You can do this by looking at your home water bills and calculating your gallons per capita per day and/or you can use an online water use calculator which gives you a chance to estimate how much water you're using. You can also use a calculator to see how much less water you could be using by changing fixtures and/or appliances and/or habits. We provide links to two online calculators below, one a quick and easy calculator from the USGS, the other a broader and deeper calculator from the Pacific Institute that also looks at the carbon footprint of your water usage. Please email Stuart Braman (sbraman@ldeo.columbia.edu) with any comments or questions.

WECalc, more than a water use calculator, is a home water-energy-climate calculator that estimates home water use, the energy use associated with home water use and the greenhouse gas emissions that result. At the end WECalc offers suggestions for reducing water use, energy use and carbon footprint. WECalc was made possible with support from the Argosy Foundation.
