Oak Street sewer separation upgrades

This project will result in 1 kilometre of new sewer pipes with a life expectancy of about 100 years.

Separating a sewer system 

We are replacing aging combined sewer infrastructure along Oak Street, West 70th Avenue, and Fremlin Street with separated pipes. 

The upgrade of the sewer system will:

  • Accommodate population growth in the Cambie Corridor
  • Effectively manage heavier rainfall expected with climate change
  • Handle higher capacities of rainwater and sewage separately 
  • Help protect the water quality in the Fraser River

The project is primarily funded by developers through the Development Cost Levy, with additional funding from local development projects.

What's happeningConstruction on West 70th Avenue is underway

Construction on West 70th Avenue will take place from Fremlin Street to Oak Street until summer 2024.

There will be temporary removal of parking and changes to access. Watch for signage.
