Backflow Prevention Program


To protect Burr Ridge's drinking water system, the Village has an active backflow prevention program. This program, in accordance with Illinois Environmental Protection Agency (IEPA) regulations, requires businesses and residents to have backflow prevention devices in place wherever there is a potential for contamination or pollution of the Village's water system through backflow. The most common device is a Reduced Pressure Zone (RPZ) backflow preventer, which is required on all underground lawn sprinkler systems. If you are unsure if a backflow device is installed at your property, please contact a licensed plumber to assist you.
 

Annual Testing Required

If you have a backflow prevention device in your home or business, the device must be inspected annually by a licensed plumber. Homes with a water meter larger than 1" in diameter and homes with sprinkler systems also require the installation of RPZ devices and must have them inspected yearly.

Letters are sent by the Village's contractor, Backflow Solutions Inc (BSI), as testing reminders just prior to the one-year anniversary of the previous year’s test date. The test date varies for all residents and can be in the fall or winter months if their backflow device is located inside the residence or building.
 
In addition, the Illinois Environmental Protection Agency (IEPA) requires that all water systems conduct a biennial survey of the water system to determine where cross-connections exist.
