Smoke Testing

Smoke testing is a useful tool in the detection of sources of infiltration where ground water and storm runoff can enter the sanitary sewer system. After a section of the sewer system has been isolated, non-toxic smoke is forced into the pipe at the manhole using blowers. The forced smoke will escape through any openings in the pipe and appear on the surface. These locations are documented and photographed for evaluation. This procedure is most effective when performed during dry weather conditions.
