Biosolids Pipeline Corridor Project

The City of Saskatoon’s (City) Wastewater Treatment Plant operates a Biosolids Handling Facility in the Rural Municipality of Corman Park (RMCP), north of Saskatoon. The Biosolids Handling Facility has a series of settling lagoons that play a critical part in the wastewater treatment process. Biosolids generated at the wastewater treatment plant are dewatered at the facility and ultimately, fertilizer is produced for nearby landowners.

Two pipelines run underground from the Wastewater Treatment Plant to the Biosolids Handling Facility. The pipelines, constructed in 1984 and 2005, must be replaced as geometric constraints and poor physical condition have made it impossible to remove the hard substances that form and accumulate on the pipeline walls. The new pipelines will have higher capacities and will be designed to mitigate the blockages that have plagued the existing pipes for many years.

The City has opted to include water and wastewater lines within the pipeline corridor that will provide service to the City of Martensville. These pipes are required for future growth of the community as well as meeting regulatory compliance with the Water Security Agency.

The preferred pipeline route as shown was developed by utilizing existing rights-of-way within the RMCP. The routing was developed with a number of considerations including: environmental impacts, operational and maintenance considerations, resident disruption and future development.

While the timing for impacting specific areas is still undetermined, the general project schedule will entail:

• Spring 2026: Construction Kick-Off
• Fall 2027: Construction Completion

2026 Construction Phases

Phase 1: WWTP & Silverwood Dog Park/Meewasin

Beginning the week of April 13, 2026

Work in this phase consists of Horizontal Directional Drilling (HDD) and open‑cut pipeline installation. HDD method was chosen to allow the dog park and golf course to stay open during construction.

• HDD operations will run 24 hours a day, 7 days a week.
• Residents and businesses should expect continuous activity, including some night‑time noise and lighting, throughout this phase.
• 24/7 work is expected to conclude by early to mid‑July.
• To reduce impacts, crews will use noise‑mitigation measures where feasible and will direct lighting away from nearby properties.

Phase 2: Wanuskewin Road (South & North of Marquis Drive)

Beginning the week of April 27, 2026

• Work in this phase includes HDD and open‑cut pipeline installation along Wanuskewin Road for both south and north of Marquis Drive.
• Lane closures and traffic detours will vary throughout construction in this phase.
• Pedestrian and cyclist pathways will remain open or be detoured on both the north and south sides of Marquis Drive.

Phase 3: Wanuskewin Road (North of Marquis Drive)

Beginning the week of May 21, 2026

• Work in this phase continues HDD and open‑cut pipeline installation along Wanuskewin Road north of Marquis Drive.
• Lane closures and traffic detours will vary throughout construction in this phase.
• Pedestrian and cyclist pathways north of Marquis Drive will be closed, while pathways south of Marquis Drive will remain open.

Phase 4: Full Closure of Wanuskewin Road (North of Marquis Drive)

Beginning the week of August 10, 2026

• Work in this phase involves open cut pipeline installation requiring a full closure of Wanuskewin Road north of Marquis Drive.
  • Southbound Highway 11 traffic intending to access Wanuskewin Road will be detoured to Highway 12/Idylwyld Drive.
  • Northbound traffic will be detoured at Marquis Drive.
  • Pedestrian and cyclist pathways north of Marquis Drive will be closed, while pathways south of Marquis Drive will remain open.
