Cross Connection Control (Backflow Prevention) Program
As required by the Illinois Environmental Protection Agency and the Department of Public Health, Every drinking water system in Illinois must have a cross connection control program, more commonly known as a backflow prevention program. Backflow prevention is designed to protect the public water supply from contamination from non-drinkable sources. For this reason, the Village of Deerfield created a cross connection control program with the goal of ensuring the quality of Village supplied water and protecting water customers.
The Village of Deerfield has contracted with Backflow Solutions, Inc. (BSI) to manage the Village's backflow inspection program. BSI has experience managing similar programs for municipalities across the Chicagoland area. BSI will serve as the primary point of contact for backflow inspections within the Village and can be contacted at (800) 414-4990 or through their website at www.bsionlinetracking.com.
Water customers with previously registered backflow devices will receive a notification and reminder directly from BSI Online that testing is due. The customer is free to choose any licensed backflow tester they want. Once the annual inspection is complete, the licensed tester will enter that information directly into BSI’s online reporting system. While BSI does not perform the backflow tests, they do have a comprehensive list of certified contractors that can be requested by contacting them.
For residents that do not use their sprinkler systems and do not want to continue paying for annual backflow testing, the Public Works and Engineering Department offers a backflow prevention lock program. The lock can be installed on the water shut-off valve that supplies the sprinkler system. The device costs $45 to have installed and has a annual $25 re-inspection fee that begins the second calendar year that the device is installed. To sign up for the program please print out and sign the lock agreement form and return it to the Public Works and Engineering Department at 465 Elm Street with a $45 check written to the Village of Deerfield.
