Waterbury Water Department backflow testing requirements
Waterbury operates the municipal water system and publishes a cross-connection test fee plus a penalty for failing to test or maintain a backflow device or permit a cross-connection inspection.
What testers should know
Contact the Waterbury Water Department to confirm whether the city will schedule the test, the current fee, and the property-specific inspection or reporting process.
Tester requirements: Confirm the city-administered testing process before hiring an outside tester. Connecticut certification requirements still apply to testable devices.
Important: Utility instructions can change and property-specific requirements may differ. Confirm the accepted form and delivery method before relying on this guide.
