The North Shore Wastewater Treatment Plant is a new tertiary treatment facility being built to replace the existing primary level Lions Gate Wastewater Treatment Plant on the North Shore.
The facility will feature an enclosed design and robust odour control system to prevent odour from reaching neighbouring residents and businesses, will recover heat for use in a nearby district energy system, and will include a public plaza, education, and community meeting spaces. Construction officially began in late August 2018. In 2019, the decision was made to move from secondary to tertiary treatment technology. In 2022, Metro Vancouver and PCL Constructors Westcoast Inc signed a pre-construction services contract to take the next steps to complete the North Shore Wastewater Treatment Plant and to create an updated plan to complete the project, including developing a revised project budget and schedule that is anticipated for 2023.
