Project 22-2456
Streets affected: Burnhamthorpe Road East to the Queensway East
Advance notice
Peel Region will be rehabilitating the existing sanitary sewer system and associated maintenance holes (commonly called manholes) in your neighbourhood/area within the next two years, as shown on the attached map.
The Lower Cooksville Trunk Sewer is a large underground pipe that transports wastewater from homes and businesses to Peel’s water resource recovery facilities. Wastewater is created when water goes down a drain or toilet. This sewer runs through environmentally sensitive areas and parkland and is now reaching the end of its useful life, requiring rehabilitation to maintain a safe and reliable service.
This project is part of the Region of Peel's broader commitment to responsible infrastructure stewardship and long-term service planning. Rehabilitating this sewer now—before issues arise—helps reduce the risk of costly emergency repairs, service disruptions, and environmental impacts to nearby parkland and Cooksville Creek. By taking a proactive approach, Peel can extend the useful life of this infrastructure while minimizing disruptions to the public through careful planning, trenchless technologies, and phased construction.
Important note
Construction will take place in the municipal right-of-way and within easements.
- The municipal right-of-way includes the street and the municipal-owned land between the street and the water service box, a small, round, metal valve located outside on the property line between your home or business and the road.
- An easement is where Peel Region has legal access to enter your property to maintain and improve Peel’s infrastructure.
Since this project is in the early stages of planning, the exact location of this work may change. We’ll provide an updated map closer to the start of construction.
Before construction begins
Before construction starts:
- We'll use spray paint or flags on roads, driveways, and lawns to locate underground gas, hydro, and cable.
- We may drill holes in the road or municipal right-of-way to collect soil samples, determine ground conditions, or confirm utility locations.
- We’ll take pictures and videos to help restore the area as close as possible to its former condition, after construction.
We expect these activities to happen between November 2025 and April 2026.
Temporary Trail and Park Closures
Temporary closures may be required along / within the following trails and parks during construction. We’ll deliver more detailed information closer to the start of the project:
- Burnhamthorpe Trail
- Cooksville Creek Trail
- Stonebrook Park
- Cooksville Common
- Richard Jones Park
- Cooksville Park
- Queensway Trail
Keeping you informed
We’re currently in the early planning stages, so we cannot give exact dates. As your city’s future planning activities may change, we may also update our plans to improve sanitary sewers. We’ll deliver more detailed information closer to the start of construction.
We understand construction can be disruptive, and we appreciate your patience as we work to improve our community’s infrastructure. This work both maintains and improves Peel’s world-class water systems, allowing us to provide reliable wastewater services to support a thriving community for life.
