Stockholm Junior Water Prize is a competition for students aged 15 to 20 who have developed school projects that can help solve major water challenges. The competition attracts thousands of entries from almost 40 countries.

Stockholm Junior Water Prize ceremony has been held every year since 1997 and has become a popular part of the World Water Week. The participants in the final round are winners from national competitions, and their work were carefully reviewed by a jury of international water experts. The prize is awarded to the winning student or group of students by The Prize’s patron HRH Crown Princess Victoria of Sweden.

Over the years, many ideas that started as Stockholm Junior Water Prize projects have proven to be important innovations that changed the lives of both the participants and their communities. Many previous winners have gone on to pursue successful careers within the water world and they have testified that the competition helped spark their interest in science and influenced their career choices.
