southwest marpole upgrades construction

Southwest Marpole Infrastructure Upgrades

We’re upgrading critical water, sewer, and street infrastructure in the southwest portion of Marpole. Construction will occur on various streets from 64th to 70th Ave, and Cartier to Osler St. 

The existing water and sewer lines are at capacity and upgrades are required to help serve this growing neighbourhood. We’ll replace the existing sewer trunk with a larger-capacity and separated sewer system – with one pipe for rainwater runoff and another pipe for sanitary sewer. 

The new storm mains will accommodate new rainfall intensity with a design that accounts for climate change.

The project will also rehabilitate sections of 67th Ave and Cartier St, and improve safety for people walking along routes to David Lloyd George Elementary School.
