The City of Elgin Public Works Department and Sewer Systems Evaluations, Inc. will perform smoke testing on the storm and sanitary sewer systems in the neighborhood surrounding North Commonwealth and Demmond, starting on Tuesday, September 14th, at approximately 7:00 a.m.
The sanitary sewer system in the area backs up when it rains, which has caused some localized flooding during significant rain events. The purpose of this testing is to gain an understanding of any cross connections that may exist between the sanitary and storm sewer systems so that department staff can schedule the necessary repairs.
Smoke will be blown through the sewer system to determine where there might be a possible leak or improper connection. Smoke may appear from cracks in the pavement above a sewer or around homes that have foundation drains connected to the sewer. Smoke will also be seen coming from all plumbing vent pipes of homes connected to the sanitary sewer system.
The smoke is non-toxic and harmless, so there will be no need to contact the fire department. It will naturally and rapidly dissipate without leaving a residue or odor. The testing in the area will continue throughout the week, although the smoke testing of a specific block will only take a few minutes.
