Constructed Wetlands for Wastewater Treatment Plant Resilience
Implementing Partner: Build Change
Project name: Constructed Wetlands for Wastewater Treatment Plant Resilience in Canada
This project evaluates wetlands’ ability to manage partially treated wastewater during extreme storm events, using a once-in-100-year rainfall simulation in Vancouver.
It examines how climate change amplifies storm intensity and flood risks, often leading to wastewater overflows that contaminate nearby rivers and lakes.
By analyzing wetland resilience in the Pacific Northwest, the study aims to enhance future climate adaptation strategies, improving stormwater management and protecting vital ecosystems from climate-driven disruptions.

Impact
1
Ammonia removal rates were analyzed to assess wetland efficiency in wastewater treatment during heavy storms. This evaluation provides valuable insights into their resilience under extreme weather conditions and fluctuating water levels, informing future climate-adaptive water management strategies.
2
Vertical flow wetlands proved highly effective in managing wastewater during floods, showcasing strong treatment performance and adaptability to storm intensity variations. Their resilience under extreme conditions highlights their potential as a reliable solution for flood-affected areas.
3
These wetlands improve municipal wastewater treatment resilience by adjusting to intense storms and fluctuating water levels. Their adaptability provides a sustainable solution, reducing pollution risks and strengthening environmental protection during extreme weather events.
