Amsterdam International Water Week The Amsterdam International Water Week (AIWW) is a global movement towards a sustainable water environment. This biennial event gathers experts from cities, industries, and utilities from all over the world to combine real-life water cases with innovative solutions. And so creating a circular and resilient water environment in high-density living areas. In 2017 we hosted the fourth edition of this event and we are looking forward to the next edition (our fifth anniversary) in 2019.
