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. •
