Cross Connection / Backflow Preventer Water Use Survey
Why did I receive a water survey from the City and Aqua Backflow?
The Illinois Environmental Protection Agency (IEPA) requires every water supply to develop and implement a cross connection (backflow prevention) control program.
A requirement of the program is to send a survey to all residential water customers every two years. Initial survey requests were sent out earlier this year. If you received another survey (a 2nd Notice), it is because your first response was never received. All water customers are required to complete and return this survey, which takes only a few minutes.
How do I respond to the survey?
Residents may complete the survey by filling out the card that was mailed and returning it to the address noted on the survey. Surveys can also be dropped off at City Hall or at the Public Works facility. The form can also be faxed, both sides, toll-free to 866-777-2125.
The survey can also be completed online. Residents may go to www.aquabackflow.com, click on the Forms tab, enter the password of “stc”, and complete the appropriate survey. Please note there are some required fields but not all fields need to be filled in.
What is a cross connection and a backflow preventer?
Cross connections are potential connections between a potable water supply and a non-potable source, where it is possible for a contaminant to enter the drinking water supply. Cross connections should be protected by a valve called a backflow preventer. A backflow preventer is a device that allows the water to flow only in one direction and prevent the piping or device hooked to the water supply line from flowing back into it.
Backflow preventers are the property of the water customer and the responsibility lies with the customer for required annual testing and maintenance. The water customer must contract with a licensed tester to perform the required annual tests and any necessary repairs. Most plumbing contractors are now certified to test backflow preventers.
Where would a backflow preventer be found on a water customer’s piping?
Residential backflow preventers may be found on lawn irrigation systems, hot water heating (boiler) systems, swimming pool fills, water features, etc.
What happens if I do not fill out the survey?
All water customers are required to complete and return this survey. There are no penalties or fines for not completing the survey. However, we encourage everyone to complete the survey to assist the City in compiling accurate records and meeting compliance with IEPA.
