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 over 140 countries, the membership of the International Water Association (IWA) brings together scientists, researchers, technology companies, and water and wastewater utilities.

Being the largest membership association in the global water sector the Association builds on a 70 years heritage of connecting water professionals and started official operations in 2000. The 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 Thought Leadership

Recognised for their unique and significant long-term contributions to advancing water science and management


Responding to global water challenges, IWA progressive agendas support sustainable urban and basin-related water solutions.

This international port city is no stranger to shifting tides. With limited land to collect and store rainwater, Singapore has faced drought, floods and water pollution in their early years of nation building.

Metro Pacific Water

As an investment company, Metro Pacific water is committed to investments in water utilities through Public Private Partnership in both green and grey infrastructure. With water utilities largely responsible for shaping the built environment, incorporation of Nature Based Solutions (NBS) to complement traditional infrastructure can be recognised as key to building sustainability and climate resilience.

Skanderborg Forsyning

The Danish water utility Skanderborg Forsyning affirms that when it comes to water security in a changing climate, using nature-based solutions at the local level was never a question. Climate change projects are an opportunity to adapt using nature to deal with increased rainfalls and prevent the flooding of urban areas.
