19th IWA LET Conference: call for papers is open!

The International Water Association (IWA) is excited to open the call for papers for the 19th IWA Leading Edge Conference on Water and Wastewater Technologies (LET 2024). We invite you to share your expertise, research, and insights at this premier event, set to take place in Essen, Germany on 24-28 June 2024.

The official theme chosen for the 19th Leading Edge Conference on Water and Wastewater Technologies (LET 2024) is “Closing the water cycle through efficient and innovative technologies”. This is a dynamic subject and one for which LET is ideally placed to provide leadership. Closing the water cycle is crucial to ensure sustainable water resource management by minimising waste, optimising resource utilisation, and addressing the growing challenges of water scarcity and pollution.


We invite you to submit a paper

Your active participation will be instrumental in shaping the discourse and driving innovation within the fields of water and wastewater technologies. We strongly urge you to contribute your valuable insights and submit your contributions to help make this conference an excellent event.

The conference technical programme will consist of platform presentations, poster presentations, workshops and panel discussions. Selected posters will be on display for the duration of the conference. Outline papers are now invited on the respective topics and should be submitted online. For more information on the topics, templates and submission details, please see the official conference website iwa-let.org or download the call for papers.
