Find out how much water and money you could save by improving household water efficiency.
The Water Saving Potential Calculator helps you estimate how much water, money, and environmental impact you can save by improving your water-use habits and upgrading to water-efficient fixtures. Whether youβre a homeowner, tenant, landlord, or business owner, this tool gives you a clear picture of your current water usage versus potential savings.
