North Central Drainage Project
The North Central Drainage Project is a three-year project to reduce the risk of surface and basement flooding. This project will replace and upgrade the storm sewer system along both 2nd Avenue and Athol Street.
Project Outcomes
- Installation of new storm sewer mains
- Reduced risk of basement and street flooding in the area
- Approximately 50 homes will see a reduction of ponding directly impacting their property
- Approximately 10 ponding areas that are looking to be reduced

North Central Drainage Project
To reduce the risk of surface and basement flooding, the North Central Drainage Project will replace and upgrade the storm sewer system along both 2nd Avenue and Athol Street.
Looking south at the intersection of 2nd Avenue and Athol Street. The middle excavator is removing the existing storm main and ground to install the new reinforced concrete pipe.
The vault structure in the intersection of Athol Street and 2nd Avenue. The vault is required due to the size of pipe coming into it. Once installed, barrels placed onto and from the surface look like any other manhole.
The excavator delivering the concrete pipe to install in the newly excavated trench.
The storm and residential sewer services for a private home reconnecting to the existing mains to restore their services after the watermain was installed on Athol Street.
Installed storm main west along 2nd Ave as well as the reconnected domestic main in the intersection of 2nd Ave and Argyle St.
Newly installed reinforced concrete pipe with maintenance access along 2nd Ave.

This carrier pipe will house the 200mm PVC wastewater pipe. This work is part of some re-routing work that is needed to take place to allow installation of the large diameter (1600mm) storm pipe.

This view is looking south towards 600 Block Athol Street. These two pipes will allow stormwater from North Central to cross under the train tracks and enter into the North Storm Channel. A special coring methodology was used to install these pipes under CN rail.
A concrete box structure is installed on either side of CN rail to allow access to these pipe crossings.
Concrete pipe is on-site ready to be installed further south along Athol Street and further north through Pony Park to connect to the North Storm Channel.
Sending a smaller pipe along the path of where the new pipe is going as a helpful guide.
This is the 1.5 meter diameter steel pipe that will be installed under CN Rail. This pipe will support and will contain the plastic (PVC) pipe that actually is used to transport storm water.
This is the 1.2 meter diameter plastic (PVC) pipe that will be within the steel pipe used to transport the stormwater from the North Central neighbourhood to the North Storm Channel.
Concrete vault structure installed on either side of the CN rail pipe crossing. The pipe travels through Pony Park and into the North Storm Channel.
The North Central Drainage Upgrade will help prevent ponding during large storms and reduce the risk of basement and street flooding, benefiting approximately 450 homes within this neighbourhood. Over the duration of the project, about 24 blocks will be impacted.
The project will be very intrusive to the community and each block will have various levels of construction from curb to curb.
In future phases, residents may be without water for emergency shutdowns of eight hours for short term water pipe replacements. If residents are on a block receiving full block water main replacement, they will be connected to the water system through an above ground water connection for the duration of the water main replacement until they can be safely returned to the underground water system.
