How much water do you use everyday in your home? Would you be surprised to learn that according to the USGS the average American uses between 80-100 gallons (approx. 300 - 375 liters) of water per day?  Do you think people in other parts of the world use more or less water than Americans? Well, this collaborative project will help you find out the answers to these questions. By collecting data on water usage from people around the world you will be able to see how your water use compares to others and determine what you might do to use less water.
