The City of Croswell will be smoke testing sewer lines throughout the City from 8:00am to 4:00pm starting August 13th thru August 17th
The City of Croswell will be doing smoke testing to the sanitary sewer lines in your area.

These tests involve blowing harmless smoke into parts of the sewer system to find damage, improper connections, and where unwanted water may be entering the City’s sewer system.

As a result, smoke may be seen coming from roof vents, building foundations, catch basins, clean-outs, down spouts, sewer laterals or manhole covers. The smoke will not enter your home or business if it is properly plumbed, vented, and the water traps contain water.

Recommendation For Residents: If you have a bathroom or plumbing fixture that is not used or is seldom used, traps should be filled by running water in the fixtures the day before scheduled smoke testing begins.

Water can evaporate from unused plumbing fixtures and Sewer gases can enter the home. Water should be added on a monthly basis thereafter in order to prevent sewer gas from entering the home or office.

The smoke used is a non-toxic substance that is harmless to humans, pets, food, and material items. The smoke could potentially cause some minor irritation to nasal passages. Any irritation will be temporary and should quickly disappear after exposure has ceased.

Persons with heart and respiratory ailments should leave the house during the test. House pets will react in a manner similar to a prudent person and leave the Smokey area. If an exit is not available be sure pets are provided with proper ventilation.

If smoke does enter the building, it will clear in a few minutes with proper ventilation. Please advise a representative of the smoke testing crew if any leakage occurs in your home or business.

Additionally, if you have any questions about the test, health issues or any other concerns, feel free to ask a crew member, or contact Dept of Public Works at 810-679-3158

Your presence is not required during the tests, and all public safety authorities will be notified of this event. We would appreciate it if you would mention this notice to your neighbors in case they have not received a notice.
