Smoke testing is a cost-effective method of identifying possible issues within the sanitary sewer system. The vapor test results are used to pinpoint areas of the sewers which may require further investigation or immediate repairs. The results also help locate leaking manholes, structural issues such as cracks, improper sewer connections, and private-side sources of inflow and infiltration.
The 2022 sanitary smoke testing project is managed by the RMOW and administered by R.F. Binnie & Associates Ltd. Works will be completed by C3 Mainline. The smoke testing is scheduled to take place from August 22 through August 31, 2022.
Neighborhoods scheduled for testing
- Alta Vista
- Bayshores & Millar’s Pond
- Benchlands North & South
- Emerald Estates
- Function Junction
- Whistler Cay
- White Gold & Spruce Grove
During smoke testing, field crews blow air and smoke into the sanitary sewer system in the street and monitor where the smoke escapes the system. The smoke under pressure will fill the main line as well as any connections and then follow the path of any leak to the ground surface, quickly revealing the source of the problem.
For instance, if smoke permeates up through the ground, it indicates breaks in the sewer line. Only enough force to overcome atmospheric pressure is required and smoke should escape from building roof vents.
The smoke should not enter your home from the sanitary sewer lines if your sink and drain traps contain water. If the smoke does enter your home, this is an indication that sewer vapors also have the potential to enter your home and minor corrections may be needed to your plumbing.
