Sanitary Sewer Smoke Testing and Condition Assessment

As a part of our infrastructure maintenance program, BioMaxx Environmental will be conducting a condition assessment of our town’s sewer system through smoke testing, a safe and effective method used to identify leaks, cracks, and improper connections in sewer pipes. 

This work is expected to begin on June 21 and could continue for up to two weeks. We will notify our residents once the assessment is complete. 

A link to our FAQ PAGE is below.


What is smoke testing?
A sanitary sewer system is designed to carry wastewater to a treatment facility. Smoke testing is one of the most effective and safe ways to assess the condition of our sewage infrastructure to ensure we continue maintaining a reliable system. It helps us to identify and locate any existing issues within a sewer pipeline so repairs can be made, if defects are found.

During the testing process, a harmless, non-toxic artificial smoke is injected into sections of the sewer system to see where it surfaces. In a properly functioning system, the smoke will exit through places such as manholes and plumbing vents on rooftops.

How should residents prepare their homes?
Before this work begins, residents should pour water into floor drains, sinks, tubs, showers, and toilets, especially those that are rarely used. The water contained in the plumbing traps create a seal that helps prevent the harmless test smoke from entering the home. Areas that are used infrequently, such as basement floor drains, utility rooms, garages, or secondary bathrooms, are most likely to have dry drains.

Is the smoke hazardous?
No. The smoke used for testing is a non-toxic, non-staining product commonly used for sewer system inspections. It’s safe for people, pets, plants, clothing, furnishings, and property, and it does not create a fire hazard.
