CONDUCTING A HOUSEHOLD WATER AUDIT
WHAT IS A HOUSEHOLD WATER AUDIT?
A household water audit is an assessment of how much water is used and how much water can
be saved in the home. Conducting a water audit involves calculating water use and identifying
simple ways for saving water in the home.
WHAT ARE THE BENEFITS OF CONDUCTING A WATER AUDIT?
Conducting a water audit can help you save money by reducing your home water bill (and sewer
bill if you are connected to a public sewer system). Conducting a water audit will make you
aware of how you use your water and help to identify ways you can minimize water use by
implementing certain conservation measures. It is possible to cut your water usage by as much
as 30 percent by implementing simple conservation measures and without drastically modifying
HOW DO I CALCULATE WATER USAGE IN MY HOME?
It is important to realize that water use throughout the year often varies with the season. Most
people use more water in the warmer months for gardening, washing cars, and other outdoor
uses. If you conduct your water audit in the winter or fall, you should still consider the
additional water you use in the summer months. The American Water Works Association
(AWWA) estimates that the average indoor water use per person is 94 gallons of water per day;
this does not take into account outdoor water use (watering lawns, washing cars).
Calculating Water Use From Your Water Bill
If you obtain water from a community water system, you probably
receive a water bill that tells you how much water you use. Many water
utilities provide customers with bills that contain information regarding
the amount of water consumed and average daily consumption during
the billing period. If the average daily consumption is not provided,
you can calculate it by dividing the total amount of water used by the
number of days in the billing period. Determine whether your water is
measured in cubic meters (m3), cubic feet (ft3), gallons (ga
