What exactly is a Smoke Test?
A 2-man or 3-man crew from the Sewer Division will use a high capacity blower smoke technique to test each sewer line. Smoke blowers are placed on manholes and smoke is blown through the sewer system. Anywhere the smoke exits, there is potential for stormwater to enter the sewer system.
