Cross Connection Control Program

What Is a Cross Connection Control Program?

This is a combined cooperative effort between plumbing and health officials, municipalities, and property owners to establish and administer guidelines for controlling cross connections and ensure their enforcement so that the public drinking water supply is protected both in the city water distribution system and within buildings to the point of use.

Our program consists of the following components:
  • Annual testing: All backflow prevention assemblies will be tested once a year by certified testers.
  • Cross connection survey: All industrial, commercial, and institutional facilities’ plumbing systems will be inspected to determine if cross connections exist.
  • Installation of protective devices: Backflow prevention devices or assemblies will need to be installed where known unprotected cross connections exist.
  • Public education program: We will inform our water customers with newsletters, brochures, public awareness meetings, cable access channel programming, and access to informational videos. Visit the following websites for more information and resources:
