Sewer Smoke Testing

THE PROGRAM IS COMPLETE.  Thank you to all residents for their cooperation and patience!

The City is conducting a program to identify locations where storm water is entering the City sanitary sewer system. The study includes smoke testing of the sanitary sewers and detailed manhole inspections.

Smoke testing is a simple means of locating openings in the sewer system that allow surface rainwater runoff to enter the sanitary sewers. Air combined with non-toxic smoke is forced into the sewer at manholes, usually located in the street, filling the system. Smoke will appear where there are defects in the main sewer line (usually located under the road) or laterals (connection between the main sewer line and a building) or where other connections to the sewer system exist, such as roof drains, patio drains and footing drains.

The smoke is non-toxic, low odor, creates no fire hazard, leaves no residue, dissipates quickly, and is harmless. However, if someone in your home has respiratory problems, you may wish to take extra precautions on your own, such as leaving your home until the smoke testing is completed.

Smoke testing is scheduled to begin in late July and is expected to be completed by early August, weather permitting. Additional notification will be provided by door hanger cards prior to the start of smoke testing and signs will be posted when crews are testing in your area.

For more detailed information about the testing process, please go to www.rjn.com/SmokeTesting.

A detailed map showing where we are testing along with progress status updates can be found here.
