​Project Overview

The New Westminster Interceptor is a large pressurized sewer pipe that carries wastewater collected throughout the Metro Vancouver region to the Annacis Island Wastewater Treatment Plant in the City of Delta. To ensure continued protection of public health and the environment, this aging pipe needs to be repaired.

Construction will take place along Columbia Street from Front Street to McBride Boulevard. Crews will begin construction for the most vulnerable section of pipe extending from Front Street to Blackwood Street in summer 2021. Work for this section is expected to be complete in spring 2023.

The next section of work, extending from just past Blackwood Street to the Pattullo Bridge, will begin in summer 2022 and will be completed in coordination with the upcoming Pattullo Bridge Replacement Project.

  Location: Columbia Street, from Front Street to McBride Boulevard, City of New Westminster
