Sewer backup

If you have a sewer blockage or backup problem, please contact the Division travaux publics at 450 698-3150 during our business hours. If our offices are closed, dial 9-1-1.

When such a situation is reported to us, we first determine the urgency and then find solutions to mitigate or remedy the problem as soon as possible. If necessary, we will inspect the pipes using a camera to clearly identify the problem.

Water main leakage or breakage

In the event of a water main breakage or leak, a Public Works truck identified as “Égout et aqueduc” (sewer and water main) can be seen on streets affected by a water closure. It will sound an audible signal for approximately 10 minutes before the water distribution system is closed.
