The International Water Association (IWA) is a self-governing nonprofit organization and knowledge hub for the water sector, connecting water professionals and companies to find solutions to the world's water challenges. It has permanent staff housed in its headquarters and global secretariat in central London, the United Kingdom, to support the activities, and has a regional office in Chennai, India. The aim of the IWA is to function as an international network for water experts and promote standards and optimal approaches in sustainable water management. Its membership is a global mosaic comprising 313 technology companies, water and wastewater utilities, 54 universities, and wider stakeholders in the fields of water services, infrastructure engineering and consulting as well as 7,791 individuals including scientists and researchers, with 53 governing members (2021).

IWA features regional associations, approximately 50 specialist groups covering key topics in urban water management, specialized task forces, and web-based knowledge networks.

Two significant conferences are organized by the IWA biennially: the World Water Congress & Exhibition (WWDE) and the Water and Development Congress & Exhibition (WDCE). IWA works across a wide range of issues covering the full water cycle, with four programmes – Basins of the Future (water security), Cities of the Future (urban metabolism, sustainable city), Water and Sanitation Services (wastewater management) including Water policy and regulation – that work towards achieving the Sustainable Development Goals adopted by the 70th UN General Assembly and addressing the threat to sustainable water supplies posed by climate change.
