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.
