The International Water Association is the network of water professionals striving for a world in which water is wisely, sustainably and equitably managed.

Drawing exceptional professionals from more than 140 countries, the membership of the International Water Association (IWA) brings together scientists, researchers, technology companies, water and wastewater utilities, and wider stakeholders involved in water management.

As the largest membership association for the global water sector, the Association was launched in its current identity in 2000, building on a 75-year heritage of connecting water professionals around the world. IWA is an international reference for the water and sanitation industry.

The IWA membership communities contribute and develop the IWA Agendas. Meet us at the IWA World Water Congress & Exhibition, the IWA Water and Development Congress & Exhibition and our Specialist Groups Conferences worldwide. IWA is science-driven and sets the agenda with the publication of 12 scientific journals and 40+ books per year by IWA Publishing.
