Cross Connection Control Program

The Illinois Environmental Protection Agency (IEPA) requires every Public Water Supply to develop and implement a comprehensive cross-connection control program for the elimination of existing cross-connections and prevention or protection from all future cross-connections. Regulations are in place to protect our drinking water systems.

The program requires the Village to conduct a survey of all water customers every three years. Village of Carpentersville water customers will receive a survey postcard in February of 2023.

Please follow the directions on the postcard for completion of the survey. There is no cost to you and it only takes a few minutes to complete. Surveys should be completed within 30 days of receipt of the postcard.

The Village of Carpentersville is utilizing the services of Aqua Backflow located in Elgin, Illinois to assist with program operations, including the survey. They specialize in cross-connection control program management. Please note that if you have or require backflow protection, you may be notified for compliance (testing, repairs, or installations) by Aqua Backflow. Should you have any questions or concerns, Aqua Backflow can be contacted at 847-742-2296 or 

The Village of Carpentersville’s Cross-Connection Control Program is designed to safeguard public health. We ask for your cooperation with our program, its enforcement, and any requests for information that comes from Aqua Backflow or Village staff.
