The City of Monroe Water Resources Department will begin sanitary sewer smoke testing on Monday, July 7, as part of an ongoing effort to improve the performance and reliability of the City’s sewer system. The testing will take place over approximately 12 weeks, covering 93 miles of sewer pipe.
Smoke testing is a safe and cost-effective method used to locate cracks, leaks, and unauthorized connections in the sewer system. A non-toxic, non-staining artificial smoke is blown into the sewer lines. The smoke will travel through the pipes and escape through any defects, allowing crews to pinpoint issues that need attention.

What to Expect During Testing
- Advance notice signs will be posted in affected neighborhoods.
- The smoke is designed to exit through vent pipes on rooftops and should not enter homes.
If smoke is seen inside a home, it may indicate a dry or faulty plumbing trap. Residents should ventilate the area by opening windows and call Water Resources at 704-282-4601. The smoke used is not harmful to people, pets, or furnishings and will dissipate quickly without odor or residue.
This process helps reduce sewer overflows, lowers treatment costs, and improves overall system performance.
