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.
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.

You have questions, we have answers:
Yes. Annual testing makes sure the device is in working condition. Working devices keep your family and the community safe from contamination.

The device stops the flow of non-potable water from a lawn or fire sprinkler system into a building. It is safest to keep non-potable water out of homes, businesses, and the public water supply.
You can review the paperwork attached to the device. It will list the last inspector in the paperwork. You can also search for certified plumbers, Cross Connection Control Inspectors (CCCI) or "RPZ" inspectors. The inspectors receive certification through the state of Illinois. Most plumbing companies will have a certified inspector on staff.
No you do not need a test. But you do need to file an application for a temporary waiver of testing. To request an application, email Public Works and we will send you a copy. There is a $25 processing fee and verification of proper disconnection.
Yes, but only Reduced Pressure Zone (RPZ) type devices are acceptable for lawn irrigation systems. If you have any other type device it cannot pass the inspection.

No. Because these devices connect to the public water supply, State Code does not allow it. Non compliant devices can impact the health and safety of your family and your neighbors.
