Residential Water Consumption Calculator

Notes: Utility bills are mailed every month (monthly). You can find your actual water consumption on the bill and compare it to the calculator. Calculations here are estimates and not an exact representation of your household consumption. The following variables impact household water consumption differently:

• Number of people living in residence
• Age of residents
• Fixture/appliance makes, models, and manufacturers
• Seasonal rainfall/temperature for outdoor water use
• Known or unknown leaks in household
