Smoke testing program
Annually (April through November)
The City uses smoke testing to find and get rid of connections of “clear” stormwater from the sanitary sewer. During smoke testing, we use non-toxic smoke to identify leaks or faulty connections. These faulty connections may allow rainwater into the sanitary sewer system, which can overflow in a big storm. This work lowers risks to humans and the environment from overflows. It also lowers costs to the City to treat water at the wastewater treatment plant.
During a smoke test, City crews complete the following steps:
- Send white smoke into the sewer system
- Observe as smoke comes out through holes
- Manhole covers
- Plumbing vent pipes
- Other locations where rainwater can get into the sewer system
If we plan to do smoke testing on your street, we'll:
- Notify you by mail
- Provide more information about what to expect
This project is ongoing.
