The City of Twin Falls at times works with contractors to perform smoke tests on the City's wastewater collection system. Residents are notified of smoke testing in their area, and personnel conducting the study will have proper identification and vehicles will be clearly marked and recognizable.
Smoke Testing helps the City locate leaks, breaks, and defects in the sewer system. The smoke can also help identify areas of excess water inflow and infiltration. The results of the smoke testing are used to identify sewer services that maybe experiencing issues or are in need of improvement.
The smoke used for Smoke Testing is non-toxic, non-hazardous, and manufactured specifically for this purpose. It leaves no residual or stains and has no effect on plants or animals. The smoke should not enter buildings, but if it does, it will have a distinct odor and should only last a few minutes with proper ventilation. If you do discover smoke in your structure, please open windows, and doors to allow the smoke to leave.
