An influential confluence of people and ideas
In 2000 the International Water Services Association founded in 1947, and the International Association on Water Quality founded in 1965, joined together to form The International Water Association (IWA). Journey with us!


The International Water Services Association (IWSA), formed in 1947, was the premier international organisation concerned with the provision of water supply and wastewater management to homes, industry and agriculture. IWSA’s goals of promoting international freedom in the exchange of technical, scientific and managerial experience and expertise have brought wide support from all nationalities who recognise the value of an organisation whose ideals and actions are totally independent of particular ideological, cultural, religious and economic influences. IWSA strived to constantly promote it’s principal aims of securing a maximum exchange of information on all water-related subjects.
