One of the many threats to our drinking water supply is known as a cross-connection (CC). A cross-connection is an unprotected actual or potential connection between a potable(drinking) water system used to supply water for drinking purposes and any source or system containing unapproved water or a substance that is not or cannot be approved as safe, wholesome, and potable. Connections as seemingly innocent as an irrigation system, hot tub, swimming pool, or ornamental pond can easily enable contaminants to enter potable (drinking) water lines via backflow. Backflow, caused by backsiphonage and/or backpressure, is the unwanted reverse flow of water, back into a water system. Backflow can potentially allow bacteria, chemicals or physical contaminants to enter the water system if CCs are uncontrolled. Customers unknowingly install potential CCs like these and other water-using equipment every day, but, they are unaware of the potential danger that lurks in the pipes as a result.
In accordance with the Safe Drinking water act of 1974 and our CC policy, you must have a proper device to protect against backflow. If you have a CC on your property without adequate protection, you are in violation and must take action immediately.
