Cross-Connection Control Program Frequently Asked Questions

1. What is a cross-connection?

A cross-connection is a connection or potential connection between any part of a potable (drinking) water system and any other environment containing other substances in a manner that, under any circumstance, would allow such substances to enter the potable water system.

2. What is a CCC Program?

An approved CCC program is an organized, legally implemented and structured program to eliminate and control all actual or potential cross connections to the municipal potable (drinking) water supply.

3. What is a backflow condition?

The undesirable reversal of flow in a potable water distribution system as a result of a cross-connection. There are two types of backflow: backpressure and backsiphonage.

4. What is backpressure backflow?

Backpressure backflow is backflow caused by a downstream pressure that is greater than the upstream (supply) pressure.  Increases in downstream pressure can be created by pumps, temperature increases in boilers, etc.

5. What is backsiphonage backflow?

Backsiphonage is backflow caused by a negative pressure (a vacuum) in a potable water system.

6. What is a backflow prevention assembly or backflow preventer?

A backflow preventer is a means or mechanism to prevent backflow.
