State and federal regulations require the City to operate a Cross Connection Control Program to reduce the chances of an accidental contamination of the public water supply caused by the backflow of water from a customer’s plumbing system into the public water mains.
Cross connections are found in all plumbing systems. It is important that each cross connection be identified and evaluated as to the type of backflow protection required to protect the drinking water supply. Some plumbing fixtures have built-in backflow protection in the form of a physical air gap. However, most cross connections will need to be controlled through the installation of an approved mechanical backflow prevention device or assembly.
