About The Project

In Oct. 2025, Metro Vancouver’s Board of Directors voted to take a new approach to upgrading the Iona Island Wastewater Treatment Plant. Rather than building an entirely new facility, Metro Vancouver will rehabilitate the existing primary treatment plant and deliver phased upgrades to achieve compliance for secondary wastewater treatment. This approach is possible in part thanks to more space-efficient wastewater treatment technology. The Iona Island Wastewater Treatment Plant Projects plan has been updated to encompass a smaller scope of work, with a new cost estimate of $6 billion, compared to the previous $9.9-billion plan approved by the Board in 2022.
