Smoke Testing

Smoke testing is a method used by utilities to check for infiltration of rainwater into a sanitary sewer system by blowing a vaporized liquid-smoke into the pipe network. This helps to identify and locate breaks, defects and plumbing faults. Please note that this is not smoke in the traditional sense. 

The smoke is non-toxic, non-staining, has a slight odor, is white to grey in color, does not create a fire hazard and cannot harm humans or pets.

Visit our Smoke Testing Dashboard to learn more about the process. You can use the interactive map to see if we'll be working in your neighborhood in the coming weeks and see a sample postcard notification sent to properties within the project area.Smoke testing crew in woods
