Backflow Prevention

Backflow prevention is the process of ensuring that potentially hazardous materials do not contaminate the City's water system through water lines.

As a water purveyor, the City of Norwalk is required by the Environmental Protection Agency and Norwalk Codified Ordinances to maintain a backflow prevention program. The city's backflow prevention program is administered through the Water Treatment Plant.

Backflow prevention includes the review of building plans as well as inspection of local commercial properties to determine the degree of potential hazard to the city water system. If a backflow preventer is mandated, the City will inform the owner and provide guidance on the process.

Owners are responsible for the annual inspection of all backflow preventers. A list of certified plumbers/testers is available by contacting the coordinator.
