Sanitary sewer smoke testing
A simple and cost-effective way to find areas that need improvement.
During smoke testing, field crews blow smoke into sewers then monitor where the smoke exits.
The Region performs sewer smoke testing to identify connection points for downspouts, catch basins and other water inlets and to see if they’re connected to the sanitary sewer or storm sewer systems.Where we are testing
Smoke testing is safe
The smoke we use for testing:
- Is odourless.
- Isn’t harmful to your health.
- Will not harm pets, clothing, draperies or furniture.
- Will disappear within minutes.

If smoke testing is scheduled in your neighbourhood, you’ll get a notice in the mail.
You do not need to be home when testing is taking place.

How to prepare for the test
Pour a few cups of water into all floor drains, sinks, showers and other plumbing fixtures when you receive this notice. This ensures that all plumbing traps under sinks, washing facilities and floor drains have water in them.
Add water to your plumbing fixtures only once. There’s no need to keep adding water.
Smoke in your home during testing
If smoke enters your home, note the location of the smoke, pour some water down the drain and open your windows for ventilation.
If you experience smoke irritation, leave the affected room and the irritation will quickly go away.
The fire department will be notified of the streets being tested. If you do not know where the smoke is coming from, contact the fire department or non-emergency communications line at 905-456-5700 and they can determine if the smoke is related to the testing or if the fire department needs to be dispatched.
For more information or to report smoke in your home during testing, call the Region at 905-791-7800, ext. 4409.
