The $9.9 billion projects at the Island of Iona Wastewater Treatment Plant (IIWWTP) in Vancouver, British Columbia, will focus on sustainable energy recovery from wastewater .

The multi-year program includes the construction of a new tertiary treatment facility and a series of ecological restoration projects and offsite works to improve the connection between infrastructure, community and environment.

Projects will be designed with local First Nations and community stakeholders in mind, with the goal of increasing the level of treatment to improve both water quality and the surrounding marine environment. Focused on sustainable energy recovery from wastewater, it will integrate with surrounding ecological restoration efforts and provide economic opportunities for First Nations entities.

The project also aims to improve seismic resilience to withstand earthquakes, combat potential sea level rise, and mitigate other anticipated impacts of climate change on the facility throughout the 21st century.

The IIWWTP projects are the largest capital program ever undertaken by Metro Vancouver, a federation of 23 municipalities, one electoral district and one treaty First Nation that collaboratively plan and deliver services across regional. As the selected PMC for the projects, global design firm Stantec will provide a multidisciplinary team of resources to provide a range of program management and engineering support services.

Completion of the IIWTP projects is currently scheduled for 2038 with commissioning of tertiary treatment in 2035.
