Lake County Public Works will be conducting smoke testing to identify locations were storm water is entering the sanitary sewer system. Smoke testing will locate 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 lines to find the location of connections and leaks. Smoke may appears where there are defects in the main sewer line or laterals (connection between the main line and a building) or where there are other connections to the sewer system such as roof drains, patio drains and footing drains.

Smoke should not enter buildings unless there is defective plumbing or dried-up drain traps. To help prevent smoke from entering your home, please pour water into infrequently used sinks, showers and floor drains. The smoke is non-toxic, creates no fire hazard, leaves no residue, dissipates quickly and is harmless.

Smoke testing will begin in mid-October and should be completed by November. Door hanger cards will be placed 24-72 hours before the smoke testing starts in your area.
