17th IWA Conference on Small Water and Wastewater Systems (SWWS) and 9th IWA Conference on Resource Oriented Sanitation (ROS)


10 NOV - 14 NOV 2024 

Welcome and invitation

Welcome to the 17th IWA Conference on Small Water and Wastewater Systems (SWWS) and 9th IWA Conference on Resource Oriented Sanitation (ROS), hosted by the International Water Association (IWA) Specialist Groups for SWWS and ROS, respectively.


After a long period of pandemic, we are thrilled to announce that we are returning to hold both Conferences in Curitiba, Paraná State, Brazil, 10th-14th November, 2024, in person.

Working in multidisciplinary teams, thinking innovatively and being bold is fundamental in order to elaborate solutions which can be carried out in future times aiming at adopting and mitigating climate change. The Conferences focus on current global and regional issues, attempting to foster innovation, as well as develop technologies and their applications to adress solutions for the challenges inherent to sustainable environmental sanitation.

Each theme is thought to create interesting and relevant discussions. This is only possible by bringing together the most influential and impactful water and wastewater researchers.

On behalf of the Programme Committee, you are strongly encouraged to participate in these Conferences through the submission of your outlines and papers on innovative and sustainable approaches. We expect to attract exciting and exceptional contributions.


These Conferences success largely depends on your participation, so please, join us in Curitiba in 2024. We confidently believe the exchange of ideas presented and 
developed by you will be stimulating.


We look forward to welcoming you to Curitiba soon!
