Cross Connection Control

Overview of the Program

All communities within the State of Illinois that provide public water supplies are required to maintain a cross connection control program (CCCP). A cross connection is any temporary or permanent connection between a public water system and a consumer’s potable water system. Typical cross connections for residential properties are auxiliary water systems, heating & cooling systems and irrigation systems. A CCCP is intended to protect the safety of water supply systems by reducing the exposure to the unwanted reversal of flow (backflow) of non-potable water through a cross connection.

  1. Under the rules and regulations of the CCCP, the State of Illinois requires that the Village perform the following:
    Conduct a biennial CCC device survey of all water customers
  2. Verify annual testing of all CCC devices
  3. Maintain detail records of all CCC devices

As stated above, a requirement of the Village’s Cross Connection Control Program is to maintain detailed records of all backflow preventers. The purpose of a backflow preventer is to allow Village water to be used at various customer locations, but not allow water to come back into the distribution system. Backflow preventers are in essence, check valves that only allow water to flow in one direction.

Backflow preventers are located on water connections throughout the Village. Most commercial and industrial properties have them. Many residential customers also have them but may not be aware of it. Backflow preventers may be located on Fire Protection Systems, Lawn Irrigation Systems, Boiler Systems, Hot Tubs and Swimming Pools.

Testing Program Requirements

Beginning in 2016, the Village began utilizing a third party contractor, BSI Online, to administer the Cross Connection Control Program. BSI Online is a local cross connection control management firm located in Worth, which serves multiple municipal clients throughout the Chicagoland area.

Per Illinois Plumbing Codes and IEPA Regulations, backflow preventers must be tested annually. These tests must be performed by a certified Cross Connection Control Device Inspector (CCCDI). Locally, most plumbing, fire protection, and lawn irrigation companies have certified testers on-staff. Under the new program, testers will enter the test results on the Village’s new eco-friendly online backflow tracking system annually. If you are a certified tester and have not yet registered, please do so for free at www.bsionlinetracking.com.

The Village of Glencoe Cross Connection Control Program is designed to safeguard public health. The Water Division of the Public Works Department requests your cooperation with this important program.  If you have or require backflow protection, BSI Online may contact you for compliance regarding testing, repairs, or installations. BSI Online can also be reached locally at (888) 966-6050 or via email at support@backflow.com with any questions.

Backflow Prevention Device Examples

Backflows due to cross connections are serious plumbing problems. They can cause sickness and even death. However, backflow can be controlled by the use of proper protection devices. The following are three examples:

Hose Bibb Vacuum Breaker
At your home, each outside spigot with a threaded connection should have a Hose-Bibb vacuum breaker installed. These are simple, inexpensive devices that can be purchased at any plumbing or hardware store for about $10. Installation is as easy as attaching your garden hose.
Dual Check with Vent

This device consists of two independent check valves with a vent chamber located between the valves. This device is generally utilized in connections to hot water heating systems.
Reduced Pressure Zone (RPZ)

This device consists of two independent check valves with a pressure chamber located between the valves. This device is generally utilized in connections to swimming pools and irrigation systems.
