About World Water Week

Organized by Stockholm International Water Institute (SIWI), World Water Week is the leading global conference for dialogue, collaboration, and innovation on water. As an independent and impartial non-profit event co-created with leading organizations, it brings together a diverse community of participants from many professional backgrounds and regions. We also maintain a longstanding partnership with the City of Stockholm, including through the Stockholm Water Prize and Stockholm Junior Water Prize.

World Water Week is held every year and centres each edition around a theme selected to both set and reflect the global agenda, aligning with UN World Water Day. The Week is designed to raise awareness of the theme, advance the debate, build new consensus, and facilitate learning across sectors.

As SIWI’s annual flagship event, World Water Week is central to our mission. Through this platform, we convene diverse actors, co-create knowledge, and strengthen capacity for more inclusive, resilient, and effective water governance.
