The Congress welcomed 2,707 participants from 90 countries, bringing together the global water community to advance water, sanitation and climate resilience in low- and middle-income countries.

Co-hosted by the Asian Institute of Technology, the Congress explored the theme ‘Water, sanitation, and innovation – pathways to progress and a resilient future’. Its comprehensive programme featured 52 technical sessions, 52 workshops, and seven forums and summit events, built around five thematic tracks:

• Ensuring Safe Drinking Water: Innovative approaches for treatment and supply.

• Strengthening Governance and Financial Systems for Long-Term Development.

The Exhibition featured 100 exhibitors and formed a key part of the event, alongside forums and special platforms, including ‘From Land to Sea: Tackling Nutrient and Plastic at Their Sources’. Discussions at the High-Level Summit culminated in the release of The Bangkok Communiqué on Water Security and Resilience, setting out shared priorities and actionable pathways towards a more secure and resilient water future.

Bangkok provided a vibrant setting for knowledge exchange and collaboration. Its blend of tradition and urban innovation reflected the Congress’s focus on sustainable solutions for the future.
