Cross Connection Control Program

 Cross Connection Control Program

In our mission to provide high-quality, safe and dependable drinking water to the community, millions of dollars are spent each year to treat and purify drinking water before it is delivered to our customers. We are constantly monitoring our distribution system for possible contamination. As an EWSU customer, you play a vital role in protecting our public drinking supply through your compliance with the Utility’s Cross Connection Control Program.

If your home or property has a lawn sprinkler system – also known as an irrigation system – it is important to check your required annual backflow preventer inspection off your list. The Indiana Department of Environmental Management and Indiana Plumbing Code require every water supplier to develop and implement a comprehensive cross connection control program for the elimination of all existing cross connections and the prevention of all future cross connections. ESWU collaborates with Aqua Backflow to implement and oversee the program.

If you require backflow protection, testing, repairs or installation, or have questions about the Cross Connection Control Program, contact EWSU Regulatory Compliance at 812-436-7015. Failure to have the system inspected annually is a violation of federal, state and local regulations – and may result in fines.
