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.

Major Components of the Cross Connection Control Program 

• Every two years the City is required by law to survey water customers.        All water customers must complete either a Residential Survey or a Commercial Survey. 
• Each year a Cross Connection Inspection and Maintenance Report must be submitted for all backflow prevention devices.
• Enforce the state plumbing code.
• Periodically contact all customers to educate them about backflow prevention.
