Sewer crews walking through a construction site

Oakridge Trunk Sewer Upgrades

We are upgrading critical sewer infrastructure along sections of W 49th Avenue, W 46th Avenue, Tisdall Street, and Fremlin Street.

This project was initiated in response to multiple flooding events that occurred during August and September 2013, and June 2014. We will replace the existing Oakridge Trunk, installed in 1957, with a larger capacity and separated sewer system – one pipe for rainwater runoff and one pipe for sanitary sewer.

The new sewer will have a life expectancy of 100 years and will help to serve this growing neighbourhood.

  • Full closure of Tisdall St from W 49th to W 49th Ave
    • Restricted through-traffic and parking
 
 
During the week of August 21, construction will begin along W 46th Ave and along Fremlin St. The construction will result in:
  • A full closure of W 46th Ave will be in effect from Willow to Fremlin St.
  • A full closure of Tisdall St will be in effect from W 46th to 49th Ave

During the first week of July, construction will begin along Tisdall St. The construction will result in:

  • Full closure of Tisdall St from W 49th to W 46th Ave
  • Restricted through-traffic and parking

Parking

During construction, changes to street parking will occur. Please ensure to watch for No Parking signs as work progresses.

Access to residences

Residential street access will be impacted by construction activities, but back lane access will be maintained.

Sidewalk access and pedestrian street crossings will be generally maintained and detoured as necessary.

What is a trunk?

A sewer trunk line collects waste and storm water from smaller sewer lines.

Waste and storm water collected in the larger trunk eventually flows to the Iona Island Wastewater Treatment Plant located in Richmond.
