The Southwest Sewer System Upgrade is a multi-year construction project that will expand the City’s wastewater network. It includes constructing a 4.5 km long large-diameter sewer line. This project will help prevent sewer backups in Southwest Regina and reduce wastewater bypass events during rainfalls. Contract 2 began in 2025.
Project Update – April 9, 2026
The Southwest Sewer System Upgrade Project has begun for 2026. This multi-year project resumes with work continuing in A.E. Wilson Park and moving into Government of Canada lands during the 2026 construction season.
The remaining work onbetween A.E. Wilson Park and Dewdney Avenue is scheduled to begin on April 13, 2026. This work will include installing pipe insulation, concrete work and asphalt paving at the intersection.
Landscaping restoration in A.E. Wilson Park will also begin in spring 2026.
Restrictions:
- Kent Street and 8th Avenue intersection closure begins April 13.
- Kent Street closure for asphalt paving is scheduled to begin mid-May.
McCarthy Boulevard Sewer Renewal
Construction resumed on McCarthy Boulevard on April 6, 2026. As part of the sanitary sewer renewal project, multiple traffic restrictions will be applied throughout the duration of the work.
What to expect:
- Bypass pumps and generators will run 24/7 to maintain sewer service, creating noise.
- Large trucks and cranes will be at multiple locations between Oriole Place and Mikkelson Drive.
- Vehicle and pedestrian traffic restrictions.
- Work may be paused when wet weather is forecasted.
Outcomes:
- Renewal of some of the largest pipes in the City, extending their lifespan for at least 50 years
- Minimal digging on the road surface
- Short construction timeline compared to open cut construction
Restrictions:
- Full road closure on McCarthy Boulevard between Mikkelson Drive and the CN railway tracks from April 11 to 12.
- North/southbound lane restrictions continue throughout the project.
Temporary Transit stops will remain throughout construction.
Project Outcomes
The Southwest Sewer Upgrade Project (Contract 1 to Contract 5) involves the construction of approximately 4.5 km of large-diameter sewer pipeline. The benefits of this project include:
- Reducing basement flooding incidents.
- Preparing for future population growth and new opportunities.
- Reducing raw sewage bypass into the environment.
Contract 2
Contract 2 includes the installation of the large diameter pipe from A.E. Wilson Park, starting near Wascana Creek and continuing south through Kent Street, crossing Dewdney Avenue and into the Government of Canada lands.
The City has also coordinated other underground and surface upgrades around Kent Street to help avoid future, disruptive construction. The majority of the additional work was completed in 2025, with landscaping and surface restoration work expected to be finished in 2026. It included installing new pipes to replace watermains, replacing storm drains and upgrading the streetscape with new pavement, curbs and gutters.
