This project, in the Ville-Marie borough, involves the rehabilitation of a century-old sewer main. The work will extend its useful life by around 50 years.

A number of sewage collectors dating back to the late 19th century are still active in Montréal’s underground. Constructed of brick, these masonry masterpieces have proven their solidity over many years, but some are now in need of restoration, including the one on Rue Ontario.

All you need to know

Where?

Rue Ontario, between Rue Saint-Urbain and Rue Sanguinet

When?

March to August 2024

Work phases

  • Phase 1 - Between Saint-Urbain and De Bullion: early March to late May
  • Phase 2 - Between De Bullion and Sanguinet: early June to late August

These interventions may be postponed or their duration extended due to weather conditions or other constraints.

What?

Phases 1 and 2:

  • Preparatory work: measuring and cleaning the collector using a mobile unit that will move to each manhole located in the roadway. A manhole is a shaft that provides access to the sewer network, including collectors.
  • Excavation work to install 5 manholes: shafts will be excavated in the roadway to install the new concrete manholes.
  • Sheathing rehabilitation work: insertion of a resin-coated sheath inside the existing sewer. Once cured, it will extend the collector’s useful life for around 50 years.
  • Reinstallation of the concrete paving stone on the roadway.

Why?

Built in 1862, this brick sewer main has structural, operational and maintenance defects. Rehabilitation work is necessary to avoid emergency interventions, which require major excavation of the street, complete closure of the traffic lane and longer-term work.
