Southwest Sewer Upgrade Project

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 3 began in October 2026.

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 1: McCarthy Boulevard Pumping Station to A.E. Wilson Park

• Scope: Installation of approximately 600 meters of large-diameter pipe from the City’s McCarthy Boulevard Pumping Station to A.E. Wilson Park (ending just south of the Rick Hansen Playground parking lot).
• Status: Completed in early 2025.

Contract 2: A.E. Wilson Park to Government of Canada Lands

• Scope: Installation of approximately 800 meters of large-diameter pipe from A.E. Wilson Park (starting near Wascana Creek), continuing south through Kent Street, crossing Dewdney Avenue and into the Government of Canada lands.

• Additional Feature: The City is capitalizing on this project to construct a new skate trail in A.E. Wilson Park, north of Wascana Creek.

Contract 3: Government of Canada Lands to Rambler Park

• Scope: Installation of 1.1 kilometers of large-diameter pipes from the Government of Canada lands, continuing south through the Royal Regina Golf Club and into the northwest corner of Rambler Park by microtunnelling trenchless technology.

• Timeline: Anticipated to start in late September 2026 and complete in fall 2027

• Traffic & Utility Impacts:
  • A temporary waterline will be installed across Dewdney Avenue in early October 2026 to supply water to the project.
  • Localized traffic restrictions are expected on Dewdney Avenue for approximately one week during this setup.
