Learn all about the project

When?

  • Fall 2022
  • Summer 2023 to the end of fall 2023

Where?

East of Avenue Louise-Lamy, between Chemin Herron and Avenue Carson.

What?

Fall 2022 and winter 2023

Preparatory work during about two months: cleaning and measuring of the collector (the large-diameter pipe for stormwater collection).

Summer to fall 2023

  • Rehabilitation of the collector with the insertion of a new pipe in the existing one (fibreglass-reinforced polyester tube or shell)
  • Repair of the two most damaged sections of the pipe (trench excavation)
  • Replacement and repair of shafts to access the collector for the project and maintenance (sewer access)
  • Measurement of the collector section located between Avenue Carson and Avenue Dawson to for later rehabilitation of that portion (separate project)

​Why?

The collector dates from 1964 and is showing signs of significant deterioration. The project includes repairs along a length of 430 metres.

This work will extend the life of the collector and will prevent the need for emergency intervention. Emergency work could have undesirable impacts on your daily life, including the need for major excavation on roads or lots, and the work could take longer.
