IWA Water and Development Congress & Exhibition

The Water and Development Congress & Exhibition 2025 will take place in Bangkok, Thailand from 8-12 December 2025. It builds on the resounding success of the 2023 edition in Kigali, Rwanda, which was a landmark event for water, sanitation, and climate resilience in low- and middle-income countries. Attracting nearly 2,700 participants from 85 countries, the 2023 Congress featured an engaging programme of 39 technical sessions, 40 workshops, and 5 forums, including the High-Level Summit on Sanitation and the Climate Smart Utilities recognition programme.

The 2025 edition is co-hosted by Asian Institute of Technology and has the overall theme of Water, sanitation, and innovation – pathways to progress and a resilient future. The comprehensive programme will be built around five thematic tracks:

• Ensure Safe Drinking Water: Innovative approaches for treatment and supply.
• Advancing Wastewater Treatment and Sanitation Services: Sustainable solutions for all.
• Smart Water Management: Integrated approaches for effective water management and planning.
• Enhancing Utility Management and Operations for Sustainable Growth.
• Strengthening Governance and Financial Systems for Long-Term Development.

Additional features and activities will include the Exhibition – a key part of the event – and various forums and special platforms, including a forum ‘From Land to Sea: Tackling Pollutants, Protecting Health, and Restoring Ecosystems’.
