The City’s Engineering Department has scheduled a contractor to perform smoke testing of the sanitary sewer system beginning June 1 2020.

The “smoke” that is manufactured for this purpose, is non-toxic, leaves no residuals or stains, and has no effect on plant or animal life. The smoke has a distinctive, but not unpleasant, odor. Visibility and odor last only a few minutes, where there is adequate ventilation.

Smoke is blown into the sanitary system that will rise from the ground to be visible, revealing areas of pipe that need to be repaired. Because the plumbing appliances in your house or commercial building are connected to the sanitary sewer system, smoke will rise through your vent pipe and out the roof. In some cases smoke may enter your home or place of business if the:

-Vents connected to your building's sewer pipes are inadequate, defective, or improperly installed.

-Traps under sinks, tubs, basins, showers and other drains are dry, defective, improperly installed, or missing.

-Pipes, connections and seals of the wastewater drain system in and under your buildings are damaged, defective, have plugs missing, or are improperly installed.

Should smoke enter your home or business without an obvious pathway (example – a dry trap) it should be inspected by a licensed plumber to determine further action.

Testing shown on the map below will begin on or around June 15th. and may take up to 4 weeks to complete.

Should you have any questions on this matter, please contact Tom Williamson, Assistant City Engineer, at 920-563-7760, or email Twilliamson@fortatkinsonwi.net.
