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

Spring 2026 Construction Activities
During the 2026 construction season (April – November), the City will be starting work in the Marquis Industrial area and Meewasin Valley near the Silverwood Heights neighbourhood.
Work will include the installation of water and sewer infrastructure through open‑cut excavations and horizontal directional drilling (HDD), resulting in phased detours and closures along on Wanuskewin Road between Arthur Rose Avenue and Highway 11. Marquis Drive and Chief Mistawasis Bridge will remain open for the entirety of the project.
Areas of the Silverwood Dog Park, including the north entrance, will be impacted by the construction during the HDD work and open-cut trenching within the park. Fencing and directional signage will be in place for park users during the disruption.
What to Expect During Construction
The City is in the final planning stages of the project and determining the timing of construction dates and phases. Please check back for schedule and other project details.
Disruptions and general inconveniences are inevitable during construction season in Saskatoon and the City thanks residents and the community for their patience while this important project is completed.
Frequently Asked Questions
Why are we doing this?
The existing sludge pipelines have reached the end of their service life. This causes operational problems for the Wastewater Treatment Plant as the pipes require frequent maintenance and are prone to failure.
Why did we pick this alignment/route?
A number of factors were considered in developing the route including environmental impacts, operational and maintenance considerations, resident disruption and future development. The route was also adjusted to avoid areas that will be affected by future Saskatoon Freeway construction. Minimizing the disruption to private property owners in terms of property access during construction was a key consideration in route selection.
Who's paying for this project?
The project is being jointly funded by the City of Saskatoon, City of Martensville and the Federal and Provincial Governments through Investing in Canada Infrastructure Program (ICIP) Funding.
How long will this project take?
Construction will begin in spring 2026 and be completed in the fall of 2027.
