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 will begin in 2025.
The second phase of Contract 2 construction is nearing completion. The contractor will continue to work in January 2026 to finish the remaining concrete chamber work and complete some preparation work for spring restoration on both sides of Wascana Creek. The pathways will remain closed for the winter as shown on the map below for public safety. The contractor will return in the spring to complete the surface restoration.
Pipe lining at McCarthy and Oriole Place will continue in the 2026 construction season as relining cannot be completed in the winter due to cold weather.
The road restriction on McCarthy Boulevard between Mikkelson and the railroad tracks will remain to provide safe navigation around the existing excavation in this area.
Temporary transit stops will remain in place throughout the winter.
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.
