World Water Week

27 August – 1 September, 2017

World Water Week is the annual focal point for the globe’s water issues. It is organized by SIWI. In 2017, World Water Week will address the theme “water and waste: reduce and reuse”. In 2016, over 3,200 individuals and around 330 convening organizations from 130 countries participated in the Week.

Experts, practitioners, decision-makers, business innovators and young professionals from a range of sectors and countries come to Stockholm to network, exchange ideas, foster new thinking and develop solutions to the most pressing water-related challenges of today. We believe water is key to our future prosperity, and that together, we can achieve a water wise world.
