Oakridge Trunk Sewer Upgrade Project

We are upgrading critical sewer infrastructure on 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. The existing trunk sewer was the likely cause, as it was built in 1957 according to criteria of the day.

The new sewer will help increase the capacity and well-being of the system, and will have a life expectancy of 100 years. 

Project details


  • W 49th Avenue, Cambie Street to Tisdall Street
  • Tisdall Street, W 49th Avenue to W 46th Avenue
  • W 46th Avenue, Tisdall Street to Fremlin Street
  • Fremlin Street, W 46th Avenue to W 43rd Avenue

Expected duration:

  • Start: March 2017
  • End: Late spring 2018

Hours of work:

  • Monday to Friday: 7:00am to 3:30pm
  • Weekends and extended hours as needed

Additional details regarding the construction schedule will be made available as the project progresses.

How this project may affect you


During construction, we are planning to maintain one travel lane in each direction on W 49th Avenue.


During construction, street parking will be removed and regulations may be changed on adjacent streets. 

Access to residences

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