The International Water Association (IWA)

The International Water Association is the network of water professionals striving for a world in which water is wisely, sustainably and equitably managed. Water underpins every aspect of human and environmental existence. The severe water challenges facing the world today require an unprecedented global response. IWA members and staff are situated in 130 countries worldwide, forming the largest international network of water professionals working towards a water wise world. Innovative, solutions- and service- oriented, we work across a range of areas that contribute to the progression of water management worldwide. Transformation cannot take place on its own in a vacuum. Rather the ideas for solutions to these challenges will be fomented and rigorously debated among the IWA’s institutions and membership.

Our programmes develop research and projects focused on solutions for water and wastewater management; we organise world-class events that bring the latest science, technology and best practice to the water sector at large; we work to place water on the global political agenda and to influence best practice in regulation and policy making; and we do this via the IWA’s global membership.
