Plumber in Carignan

4.9 out of 5

Carignan is a particular case on the South Shore: part of the territory is connected to the sewer network, part still runs on septic systems. The two situations call for neither the same work nor the same obligations.

Where the network exists, by-law 245 (2024)-1 requires a valve “whatever the year of construction”. Where it does not, the septic tank is what is regulated, with mandatory pump-outs every two years.

The City also has a little-known intervention rule that decides who pays when a backup happens.

Worth knowing in Carignan

  • A valve, whatever the year of construction

    Article 11 of by-law 245 (2024)-1 is clear: “Whatever the year of construction, the owner of any building served by the sanitary, storm or combined sewer network must install the number of backwater valves required to prevent any backup.” The number therefore depends on the building, not on a regulatory minimum.

  • The City only steps in after a plumber's finding

    This is the provision that surprises owners most: “When a sewer backup occurs in a building, the City intervenes only once a plumber or drain-clearing contractor establishes that the problem is located” on the municipal side. In practice the first call is yours, and the finding determines what follows.

  • Roots, sediment and reverse slope: on the owner

    The by-law assigns responsibility unambiguously: “The owner shall be held liable for damage caused by inadequate maintenance, by the presence of tree or shrub roots, or by non-compliance with this by-law”, and the City disclaims liability where valves were not installed.

Frequently asked questions in Carignan

Who pays if my basement backs up in Carignan?
It is decided on a finding. The by-law provides that “when a sewer backup occurs in a building, the City intervenes only once a plumber or drain-clearing contractor establishes that the problem is located” on the municipal side. The first call is therefore yours, and the finding determines what follows.
My house is old: is the valve still mandatory?
Yes. Article 11 applies “whatever the year of construction” to any building served by the sanitary, storm or combined network, and requires “the number of backwater valves needed to prevent any backup”. That number depends on the building, not on a regulatory minimum.
Am I on the sewer or on a septic system?
Both exist in Carignan. Part of the territory is connected to the network, part still runs on septic systems, with mandatory pumping every two years. Knowing which side your address falls on changes the diagnosis and the possible work.
Roots in my drain: who is responsible?
For the private portion, you: the by-law states that “the owner shall be held liable for damage caused by inadequate maintenance, by the presence of tree or shrub roots, or by non-compliance”. A camera inspection pinpoints the intrusion before any digging.
