Cross Connection Control

Cross connection control devices (also called backflow preventers, reduced pressure zone devices or "RPZs") are used to protect the Village's water supply from contaminants and pollutants. RPZs are used for fire sprinklers, lawn irrigation, and car washes, to name a few. RPZs on service lines will stop contaminants from flowing or siphoning back into the water mains.

Yes! Businesses and residences are required to test their devices at the time of installation and at least annually, or more frequently, if recommended by the device manufacturer. This requirement is mandated through the State of Illinois Plumbing Code (Section 890.1130) and the Village Code (Title 8 Section 3).

Illinois Environmental Protection Agency Title 35 Section 604.1505 requires the Village of Antioch to send out a survey notice to all water customers every three years.  You may complete the online survey below.  If you have questions or need assistance with completing the survey or would like to have a paper copy of the survey mailed to you for completion, please contact the Public Works Department at (847) 395-1881.  You may also complete a paper copy of the survey at the Village Hall at 935 Skidmore Drive during normal business hours.

The Village of Antioch partners with BSI Online to manage the backflow tracking. Notices will be sent from BSI Online reminding device holders of test dates and submission information. Please contact BSI Online at (800) 414-4990 or bsionline@backflow.com with any questions.
