Cross Connection

The City of Irving, in cooperation with the Texas Commission on Environmental Quality, has established a cross connection control program to protect your drinking water from harmful contaminants.

Irving's Ordinace #8140 requires that all customers with backflow prevention assemblies have their assemblies tested annually.  By having your assemblies tested annually, you are also helping to protect your community's drinking water supply.
