World Water Week

World Water Week is SIWI’s annual global conference on water and one of the world’s leading platforms for dialogue, collaboration, and innovation on water. Organized by the Stockholm International Water Institute (SIWI), the Week brings together decision-makers, experts, practitioners, businesses, civil society, and youth from across regions and professional backgrounds.

Why a global convening platform matters

As an independent and impartial non-profit event, World Water Week is co-created with leading organizations and partners. Each edition centres on a theme selected to both reflect and help shape the global water agenda, aligned with UN World Water Day. The Week is designed to raise awareness, advance debate, build shared understanding, and support learning across sectors and disciplines.

How SIWI contributes

SIWI organizes and governs World Water Week to provide a trusted space where science, policy, and practice meet. As SIWI’s flagship initiative, the Week is a central way we deliver on our mission: convening diverse actors, co-creating knowledge, and strengthening capacity for more inclusive, resilient, and effective water governance. While SIWI provides the overall framework and direction, the programme itself is built together with a global community of scientific advisors, partners, and contributing organizations.

What World Water Week enables

The impact of World Water Week extends far beyond the event itself. It helps catalyze new partnerships, strengthens international cooperation, and informs policy discussions across climate, development, and water governance. Ideas shared during the Week continue into institutions, networks, and processes worldwide.

Rooted in Sweden’s long tradition of environmental leadership, World Water Week also reinforces Stockholm’s role as a global hub for sustainability dialogue. SIWI works closely with the City of Stockholm and the Stockholm Water Foundation, which administers the Stockholm Water Prize and the Stockholm Junior Water Prize under royal patronage, both of which are central features of the Week.
