Smith Collector Rehabilitation Work
Between Carson Avenue and Terrasse du Bord-du-Lac–Lakeshore
Duration of the work: approximately 6 months
By the City of Montreal
A storm sewer collector is a pipe that collects rainwater from the local sewer system and carries it to larger pipes called outfalls, which then flow into waterways after minimal filtration.
The planned work involves the rehabilitation of the Smith collector, between Carson Avenue and Sims Place, using a lining technique. This work aims to ensure structural integrity, improve hydraulic capacity, correct physical deficiencies, eliminate infiltration, and extend the service life of the storm sewer.
Cleaning and inspection work is also planned on the sewer located between Sims Place and Terrasse du Bord-du-Lac–Lakeshore.
Rehabilitation by lining
This technique involves inserting a liner inside the existing sewer pipe, starting from the existing manholes. The liner is deployed using air. It is then hardened with hot water, steam, or ultraviolet (UV) light. This extends the pipe's lifespan by approximately fifty years.
This technique is advantageous because it eliminates the need to fully excavate the roadway. This results in a smaller construction site, faster completion of the work and restoration of the public right-of-way, while minimizing disruption to traffic and other inconveniences.
For the population near the collector
A liaison officer assigned to the project will contact you directly to discuss your concerns regarding the upcoming construction and will remain available throughout the project to answer your questions.
Traffic disruptions
On-site signage will indicate the guidelines to follow during the works (detours, speed limits, local traffic, etc.).
Sewer service interruption
A door sign specifying the date, time and all the details will be distributed in advance to affected residences and businesses.
Parking
Parking spaces may be used to establish a security perimeter and to store equipment and materials. Check the area signage as it may be modified as needed.
The construction site and sequence of works
The work will take place in four phases:
Phase 1 and 2: June 2026
- Cleaning, CCTV inspection, and sewer line measurement work between Sims Place and Carson Avenue;
- Design and preparation for sewer system rehabilitation work;
- CCTV inspection of the sewer lines, between Sims Place and Terrasse du Bord-du-Lac–Lakeshore;
- No excavation work and minor traffic disruptions on certain streets only for the use of a sewer truck.
Phase 3: August 2026
- Sewer line rehabilitation work and interventions between Sims Place and Dawson Avenue;
- Construction of a new manhole at Brunet Place;
- Opening, modification, and restoration of existing manholes.
Phase 4: October 2026 (Carson Avenue)
- Reconstruction work on a section of the collector;
- Construction of a new manhole;
- Rehabilitation work between Dawson Avenue and Carson Avenue;
- Reconstruction of secondary storm sewers and site restoration.
The use of tools and equipment may cause dust, noise, vibration, and some odors despite all the mitigation measures in place. Thank you for your patience.
