The World's Leading Youth Water Competition

The Stockholm Junior Water Prize (SJWP) is an international competition established in 1995 that encourages young people aged 15–20 to engage with water and environmental challenges through original research.

Organised by the Stockholm International Water Institute (SIWI) and sponsored by Xylem, the prize receives over 10,000 entries from more than 30 countries each year. National competitions serve as qualifiers, with winners representing their country at the international finals held annually during World Water Week in Stockholm.

The competition accepts projects addressing water from any angle — science, technology, social impact, policy, or engineering — as long as they propose a meaningful contribution to humanity's relationship with water. Crown Princess Victoria of Sweden serves as the prize's patron.

ATAST's Role

Tunisia's National Water Prize

ATAST organises Tunisia's national qualifier for the Stockholm Junior Water Prize — identifying and supporting the strongest Tunisian water research projects to compete internationally.

Through the national selection process, ATAST evaluates student research projects focused on water-related challenges. The national winner represents Tunisia at the international SJWP finals during World Water Week in Stockholm, Sweden — one of the world's most important water policy forums.

For Tunisia, a country facing significant water stress and resource challenges, this competition is especially meaningful. Tunisian students working on water conservation, purification, irrigation efficiency, or water policy have a genuine opportunity to make their research matter — both nationally and on the world stage.

The International Stage

Presenting to the World at World Water Week

Being Tunisia's representative at the Stockholm Junior Water Prize is one of the most prestigious achievements available to a young Tunisian researcher.

Since 1997, the SJWP international finals have been held during World Water Week — the world's most important annual gathering on global water issues. SJWP finalists present their research before an audience of thousands: water scientists, UN officials, government ministers, and NGO leaders from across the globe.

Past international winners have come from the USA, UK, Canada, and a growing number of developing nations — with projects ranging from PFAS detection to ocean carbon removal to algal bloom prevention. Every season brings a new winner and a new breakthrough idea.

Crown Princess Victoria of Sweden, the prize's patron since its founding, personally congratulates winners — making the SJWP ceremony one of the most memorable moments in any young researcher's life.
