Find a Certified Tester Near You
Green Bay Water Utility requires annual backflow assembly testing for commercial properties, irrigation systems, and any connection identified as a contamination risk, under Wisconsin's statewide cross-connection control rule. Green Bay's mix of industrial paper-mill heritage along the Fox River and its growing retail corridors both generate a consistent need for certified annual testing.
Keeping Pace With Green Bay's Industrial and Commercial Mix

Properties near Green Bay’s industrial waterfront often have more complex backflow assemblies tied to manufacturing processes, while newer commercial development on the city’s west side typically has simpler irrigation-related devices. A certified local tester can identify your assembly type and file results promptly with the utility.
