Sanitary Sewer Smoke Testing
Smoke testing is a way to locate openings in the sewer system that allow rainwater runoff to enter and can cause inconvenient and expensive sanitary sewer backups. Air combined with non-toxic smoke is forced into the sewer lines to disclose the location of leaks and connections to storm water systems. Smoke can be seen coming up out of the ground where there are defects in the lines. Smoke testing also identifies roof drains, patio drains and footing drains that are connected to the sewer system.
2017 Smoke Testing
The City of Naperville contracted with RJN Group, Inc. of Wheaton, Illinois and Burns & McDonnell of Downers Grove, Illinois to perform smoke testing. Two areas of the City were smoke tested this past summer. All scheduled areas have been completed and no further smoke testing is scheduled for 2017.
