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.
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.
Work currently underway:
July 22 to August 4:
- McCarthy Boulevard between Mikkelson Drive and 1st Avenue North will be closed to northbound traffic.
- Northbound traffic should follow the detour route outlined on the map below.
- Southbound traffic is restricted to one lane.
The timeline is subject to change due to weather delays.
McCarthy Blvd - Northbound Detour Map
June 20 to early August:
- Crews will be working to deconstruct the bypass piping network and perform repair work at varying locations. Some of this work will result in one- or two-day road closures.
- Traffic restrictions will be gradually removed as bypass components and restoration work are complete.
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:
- 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.
Contract 3
Contract 3 is anticipated to start in 2026. It includes the installation of large-diameter pipes from Government of Cananda Lands, continuing south through Royal Regina Golf Club and into the northwest corner of the Rambler Park.
