Home MenuCross Connection Control Program
Our Cross Connection Control Program exists to protect our public water system. All Union County Water customers - including residential customers with irrigation systems - are encouraged to review this page carefully to ensure compliance with this program's regulations.
This program is authorized by County ordinance and complies with the federal Safe Drinking Water Act, the North Carolina Drinking Water Act, North Carolina State Building Code, and 15A NCAC 1 SC.0406.
What is a Cross Connection?
A cross connection can occur when the County's water system comes in contact with a private plumbing system that can be a source of contamination or pollution, such as an irrigation system, a commercial kitchen, or an apartment complex's fire sprinkler system. Read more about cross connections in the County's Cross Connection Ordinance.
To protect water quality for all of our customers, Union County Water works proactively to reduce these potential sources of contamination through our Cross Connection Program. One of the primary ways we achieve this is by requiring certain customers to install and maintain backflow prevention devices as part of their connections to our public water system.
Review the information below to learn which customers are required to install and maintain a backflow prevention device and at what frequency, what vendors are approved to install and test these devices, and additional helpful information.
