Graham has been selected by Metro Vancouver as Construction Manager for the North Surrey Interceptor Storage Tank project, a major infrastructure initiative that will increase wastewater system capacity and help protect the Fraser River.
The North Surrey Interceptor is a major sewer that conveys wastewater from Maple Ridge and North Surrey to the Annacis Island Wastewater Treatment Plant in Delta, British Columbia. As the region’s population grows, additional capacity is required to manage increased wastewater volumes during periods of heavy rainfall and reduce the risk of sewer overflows entering the Fraser River.
Project Overview
The project includes construction of a new 10-metre-tall storage tank facility at 136 Street and King Road in Surrey. With a capacity of approximately 34,000 m³, the facility will temporarily store wastewater during periods of heavy rainfall, reducing pressure on the existing system and helping minimize overflows.
Additional project components include a new pump station, generator and fuel storage buildings, an operations yard, and a rooftop air-quality system designed to manage odours. Architectural and landscape features will also be incorporated to complement the surrounding natural environment.
The project marks an important milestone for Metro Vancouver as its first wastewater conveyance project to be delivered using a collaborative Construction Manager at Risk (CMAR) contract model, helping establish a foundation for the delivery of future projects.
Supporting a Healthier Fraser River
By increasing wastewater storage capacity and reducing the potential for sewer overflows, the project will support efforts to protect water quality in the Fraser River.
Metro Vancouver’s site restoration and landscaping plans will incorporate native plant species and targeted habitat enhancement measures designed to complement the surrounding environment and support long-term ecological health.
Construction Schedule
Preconstruction activities began in summer 2026, with major construction anticipated to start in summer 2027. Project completion is expected in summer 2031.
