Graham has been selected by Metro Vancouver as construction manager for the North Surrey Interceptor Storage Tank project.
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. 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.
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.
Preconstruction activities began in summer 2026, with major construction anticipated to start in summer 2027. Project completion is expected in summer 2031.
