The Salish Sea Needs Tertiary Wastewater Treatment

Did you know Metro Vancouver’s largest wastewater treatment plant, Iona, discharges undertreated sewage directly into the Salish Sea?

Current plans are for the Iona Island Plant to be upgraded by 2030. In late June 2020, the Greater Vancouver Sewerage and Drainage District Board approved the preliminary design of the Plant’s upgrade, which includes plans for tertiary treatment methods. Tertiary treatment is the best option for Metro Vancouver communities because it will prevent the largest quantity of harmful toxins like nitrogen, ammonia, metals and microplastics from polluting the Salish Sea.

Despite this victory, the fight isn’t over yet. Metro Vancouver is set to vote on the final design in on May 28, 2021. We need to ensure the right tertiary treatment methods are approved and you can help.
