What is cross connection control?

Cross Connection Control refers to the practice of preventing contaminants from entering a public water supply through backflow. This is accomplished by identifying potential cross-connections—points where potable water could accidentally come into contact with non-potable water—and implementing measures such as backflow prevention devices. Professionals in this field are responsible for inspecting, testing, and maintaining these devices to ensure safe drinking water. Effective cross connection control is critical for public health and is regulated by local and federal standards.
