Did you know Metro Vancouver’s largest wastewater treatment plant discharges micro plastics, and toxins directly into the Salish Sea?
Iona Island Wastewater Treatment Plant is our last line of defense against what goes down our drains, and what ends up in our oceans.
Unfortunately, the facility which was built in the 60's has long been outdated and now poses a serious threat to the Salish Sea.
So, Whats the Problem?
Iona is only equipped with the technology to remove large suspended solids from city and household drain outflows before being sent to the marine environment. It's called 'primary treatment', and is decades behind the times- leavingt micro plastics and toxins to flow through the facility and into the Salish Sea.
To make matters worse, the plant is located right at the Fraser River Estuary, along the Salish Sea coastline - critical habitat for endangered Southern Resident Killer Whales, salmon, and one of North America's greatest migratory bird corridors.
A Rare Opportunity for Change
Current plans for Iona Island's treatment plant includes minimum standard secondary treatment by 2030. There is no question that a higher standard - tertiary treatment - should be implemented as soon as possible to stop toxins and microplastics from flowing into the Salish Sea and Fraser River.
With planning for the upgrade underway, there is an exceptionally rare opportunity to incorporate tertiary treatment into the current upgrade. These facilities are massive pieces of infrastructure, and renovations roll around once in a generation.
If included, tertiary treatment will be a significant step towards tackling the issue of pollution in the Salish Sea, and support the health of its inhabitants and surrounding communities.
Take action and let the government know why tertiary treatment at the Iona Plant is a key step towards a healthier Salish Sea.
“The Fraser River estuary is an internationally significant natural treasure; one that includes more than 17,000 hectares of wetland supporting an immense diversity of life ranging from 1.4 million migratory birds to more than 2 billion juvenile salmon. It’s an area that deserves the highest level of protection possible...”

The Fraser Estuary, Salish Sea, and Iona Island are critical pieces of habitat for all Pacific salmon species, orcas, and migratory birds. These populations depend on a healthy Salish Sea, free of harmful chemicals, microplastics, and pharmaceuticals.
Recognized as a Ramsar 'wetland of international importance', the diversity and function of the Fraser River and Salish Sea must be considered in this opportunity for for a healthier British Columbia.
"The Fraser estuary is one of the richest and most important ecosystems for migrant and wintering waterbirds in Canada.
This Important Bird and Biodiversity Area (IBA) supports globally or continentally significant populations of fifteen species, including American Wigeon, Northern Pintail, Mallard, Brant, Snow Goose, Trumpeter Swan, Western Sandpiper, Dunlin, and Great Blue Heron. In addition, the IBA supports nationally significant numbers of Barn Owl and Peregrine Falcon. The most numerous species found here is the Western Sandpiper - one-day, peak count estimates of at least 500,000 have historically occurred during spring migration, though more recent estimates range from 120,000-180,000, which is a substantial proportion of the global Western Sandpiper population. Iona Island itself is one British Columbia’s key birding hotspots as a total of 286 different bird species have been spotted on the island. The vast abundance and diversity of birds has led to the estuary receiving a number of international designations including a Western Hemisphere Shorebird Reserve Network site of Hemispheric Importance and a BirdLife International Important Bird and Biodiversity Area.

STAGES OF WASTEWATER TREATMENT
When it comes to the 'best' treatment, what are out options?
*Biological Oxygen Demand, or BOD is the oxygen demand needed by microorganisms to digest the organic pollutants in the water. Higher BOD implies that there are more organic pollutants to digest (mg O2/litre of sample)
