Water Backflow Assembly FAQ

The Village of Tinley Park’s Public Works Department is committed to providing quality, cost-efficient service in the delivery of safe drinking water to all residential and commercial users.

Safe and reliable drinking water is a carefully manufactured product. In order to help ensure safe drinking water, the Village adopted a Cross Connection Control Program, Village Municipal Code: Chapter 52.

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. All residential water customers are requested to complete the survey, which takes only a few minutes.

Residents can complete the water use survey on our website.
