Following up from our Silver Anniversary conference, the CWA moves to Scotland to showcase some of the breadth of experience with the technology for the past three decades. We will discuss long term performance, evidence-led designs, and the latest research on constructed wetlands for improving water quality from a variety of sources.

We are pleased to announce our international keynote speaker, Dr Margit Kõiv-Vainik . Margit has conducted research on constructed wetlands under cold climate conditions for the past twenty years and will present her insights from a variety of projects looking at wetlands for diffuse pollution management in rural landscapes. See Margit's biography below to learn more about her and her work.
The conference will also include a site visit to mature constructed wetlands designer by Moir Environmental (one of our founding members!) and our dedicated New Wetland Professional sessions - with flash presentations, posters, prizes and facilitated networking opportunities in a friendly environment.
If you have insights and experiences on constructed wetlands for water quality improvement, please do consider submitting an abstract for peer-review to contribute a talk during the event. This years' themes are:
- Overcoming challenges and enabling success
- Turning policy into practice
- Achieving multiple benefits with constructed wetlands
- New approaches in wetland design and implementation
- Wetlands for nutrient control in both rural and urban settings
- Farm-based wetlands and catchment-scale solutions
- Resource recovery and circular economy opportunities
- Learning from long-term monitoring of full-scale systems
DEADLINE FOR SUBMITTING YOUR ABSTRACT
Invited Keynote Speakers
"In-Stream Treatment Wetlands for Mitigating Diffuse Pollution in Rural Landscapes in Estonia: Achievements, Challenges, and Lessons Learned”
Margit Kõiv-Vainik is an Associate Professor in Environmental Technology at the Department of Geography, in the Institute of Ecology and Earth Sciences, University of Tartu, Estonia. Her interdisciplinary research focuses on process-based development and optimization of nature-based water solutions, such as constructed treatment wetlands and sustainable stormwater solutions, to improve removal of highly problematic contaminants from polluted waters — including urban stormwater, agricultural diffuse runoff, landfill leachate, municipal and aquaculture wastewater, and greywater. She has contributed to ecological engineering and nature-based water treatment, with publications on plant-mediated pollutant removal, filter media performance, nutrient retention, and water management under cold-climate conditions.
Kõiv-Vainik’s research integrates ecological processes, phytotechnology, and environmental engineering to improve the performance and resilience of nature-based solutions under multiple stressors. Through experimental and field-based studies, she contributes to the development of scientifically grounded, climate-adaptive solutions for sustainable water management.
Margit will present on the decades of experience with treatment wetlands for diffuse pollution management in the landscape, under cold weather conditions. The work has been mainly led by Prof. Kuno Kasak (https://sisu.ut.ee/ecotech/) and carried out in collaboration with many working groups at the University of Tartu, spanning agricultural runoff and forest management areas.
