Smoke Testing for the 2017 season is complete!
The Public Works Department periodically contracts with engineering firms to conduct smoke testing to identify locations where storm water is entering the Village sanitary sewer system.
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.
Smoke should not enter your home unless there is defective plumbing or dried-up drain traps. Pour one gallon of water down all floor drains and any rarely used sinks/tubs/toilets to ensure that a water barrier is maintained in the drain traps. The drain trap water barrier prevents sewer gases or odors from entering the building. If the drain trap water barrier is present and smoke does enter your home, the potential exists for sewer gases to also enter your home and you should consult a licensed plumber to fix the problem.
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.
