Water Savings Calculator
How wisely do you use water? Understanding where and how much water we use is the first step to conserving one of our most precious resources.

Try our home Water Use Calculator to find out just how much water is used in your household and compare it to the average use of a household your size.

Explore our indoor and outdoor tips to find out how you can conserve more water. Then check back and see how much water your additional conservations efforts have saved!

A quick note: Since each household is set up with different fixtures and plumbing, this calculator provides an estimate of your water usage. It uses averages to figure your use, so the results may not be precise — but they will give you a good idea of how much you’ve reduced your water use.
