The $9.9 billion Iona Island Wastewater Treatment Plant (IIWWTP) projects in Vancouver, British Columbia, aim to recover renewable energy from wastewater.

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

The projects will be designed with local First Nations and community stakeholders in mind, with the goal of increasing treatment levels to improve both water quality and the surrounding marine environment. Centered on recovering renewable energy from wastewater, it will integrate with surrounding ecological restoration efforts and provide economic opportunities for First Nation entities.

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

The IIWWTP projects are the largest capital program ever implemented by Metro Vancouver: a federation of 23 municipalities, one electoral territory, and one First Nation state party that jointly plans and delivers services on a regional scale. As the selected PMC for the projects, global design firm Stantec will provide a multidisciplinary team of resources to deliver a range of program management and technical support services.

The completion of the IIWWTP projects is currently planned for 2038 with the commissioning of the tertiary treatment in 2035.
