Cross Connection and Backflow Prevention
Protecting your drinking water supply is also your responsibility!
State regulations require residential, commercial and industrial customers served by a public water system to protect the public water system from potential contamination. Under certain conditions water from private plumbing can flow into the public water distribution system, this is referred to as backflow. In order to prevent potential backflow, some customers are required to install and maintain backflow prevention devices on the main water service lines.
Please read the list of locations requiring backflow prevention to become familiar with State of Indiana requirements.

What is Backflow?
Backpressure happens when the pressure of the contaminant source exceeds the positive pressure in the water distribution main. An example would be when a drinking water supply main has a connection to a hot water boiler system that is not protected by an approved and functioning backflow preventer. If pressure in the boiler system increases to where it exceeds the pressure in the water distribution system, backflow from the boiler to the drinking water supply system may occur.
