Backflow Program

Buffalo Grove is dedicated to protecting the public water supply from contamination by toxic substances.

If you have recently purchased a home, you may notice a device like the photo below mounted on the side of your house. This is the backflow device for your irrigation system. This device is important because it protects the public water supply from contamination. This device requires yearly testing by a cross connection control inspector.

RPZ-Backflow-Device

This is an example of an RPZ type backflow device, mounted on the side of a single family home.  The device itself is highlighted in red.

Help! I received a letter from a company called "BSI".

We are happy to discuss homeowner responsibilities related to backflow devices in irrigation and fire safety systems that are connected to the public water supply. Please call (847) 459-2545 or submit a request here and we will get in touch with you.

Buffalo Grove has contracted with Backflow Solutions, Inc. (BSI) to manage the backflow inspection program. BSI has experience managing similar programs for municipalities across the Chicagoland area. BSI serves as the primary contact for backflow inspections within the Village. You can contact them at (800) 414-4990 or at www.bsionlinetracking.com.  If you receive a letter from BSI, it is being sent on behalf of Buffalo Grove. Please do not discard it.

You have questions, we have answers:

Does it need to be tested every year?
What does a backflow prevention device do?
Where can I find a Cross Control Device Inspector?
If I don't plan on using my lawn irrigation system, do I need a test?
Are there different kinds of backflow devices other than the RPZ type?
My lawn irrigation system is old, and it passed its original inspection, Am I grandfathered in with my non-RPZ backflow device?
