Call for Expressions of Interest to host IWRA's 20th World Water Congress in 2027

IWRA’s World Water Congress is a well-established and globally recognised event in the water sector that is held every two to three years under the auspices of IWRA in different cities around the world.  Its objective is to provide a meeting place to share experiences, promote discussion, and present new knowledge, research results and developments in the fields of water sciences and policy from around the world.  For nearly half a century, our World Water Congresses have been at the vanguard of the development and identification of major global themes concerning the water agenda, while at the same time bringing together large cross-sections of up to 2,000 stakeholders who are engaged in the formulation and implementation of decisions in the water sector. 

 We invite you to read the terms of reference to learn how you can become our next host. 

We encourage you to submit applications before the end of 2024.
