IWA Membership

Together, towards a water-wise world

The International Water Association (IWA) continuously works toward a world in which water is wisely managed to satisfy the needs of human activities and ecosystems in an equitable and sustainable way. Our members, based across 130 countries, are committed water specialists who help achieve IWA’s goal by coming together, transcending disciplines, sectors, geographies and cultures; sharing pioneering science and leading practice; and ultimately, putting together innovative water-technology solutions for the world’s pressing water issues.

Are you looking to make a difference in the world of water? As an IWA member, you will find many ways to actively contribute to changing the water practice for a better future. Choose the membership package that suits you best and become an agent of change together with us.

Your membership,
your choice

  • IWA offers different memberships types, including Individual Membership, Corporate Membership, and University Membership.
  • Membership can be taken up for 1 or 2 years and is valid from the day of activation or renewal.
  • IWA operates a High/Low Income Country classification for its membership fees (HIC/LIC).
    This classification is based on the member’s country of residence, not on the country of origin. The IWA Country classification can be accessed online.
