The City of Lebanon Public Works Department will be conducting smoke testing of the sanitary sewer system in residential and commercial areas over the coming weeks.
Smoke testing is a routine process used by cities nationwide to locate breaks or defects in the sewer system that allow stormwater to enter. Large amounts of stormwater in the system can overwhelm pipes, leading to sewage backups, higher wastewater treatment costs, and damage to infrastructure. By finding these problems early, the City can make necessary repairs and maintain reliable service.
What residents should know before testing begins:
- Safe but visible: Non-toxic, non-staining smoke will be blown into the sewer lines. You may see smoke coming from manholes, yards, or vents. It is not a fire hazard and usually dissipates within minutes.
- Prevent smoke inside: The smoke should not enter homes or businesses unless there are plumbing defects or dry drain traps. If you live in a testing area, you can pour about 24 ounces of water into all drains (basement floor drains, sink traps, and other plumbing fixtures). You may also cover sinks or floor drains with wet towels.
- If smoke enters your home:
- Do not panic — the smoke is harmless but may cause mild respiratory irritation.
- Ventilate the area by opening windows and doors.
- Leave the area until the smoke clears.
- Notify field technicians in your neighborhood or call Lebanon Public Works.
- Special needs: If you know individuals with special needs living in testing areas, please inform them of the testing or contact Public Works so crews can provide assistance.
- Timeline: Testing schedules may be affected by weather conditions. Crews will post signs in neighborhoods where testing is underway.
