Stockholm Junior Water Prize

The Stockholm Junior Water Prize is an international competition that recognizes high school students who develop research projects related to water science, technology, management, or environmental protection. Organized by the Stockholm International Water Institute (SIWI), the program encourages students to tackle real-world challenges such as water quality, access to clean water, wastewater treatment, and aquatic ecosystem health. Projects may be experimental, engineering-based, or focused on data analysis and policy, as long as they are grounded in sound scientific methods.

This program is well suited for students who enjoy independent research, have a strong interest in STEM and environmental issues, and are motivated to explore how science can address global water challenges. Participants can strengthen skills in research design, data collection, analysis, and scientific communication. Recognition in this competition can be a meaningful addition to college applications, demonstrating academic initiative, problem-solving ability, and commitment to sustainability. Many national competitions also provide opportunities to present work to experts in the field, receive feedback, and connect with other students interested in water-related science.

Who is eligible for Stockholm Junior Water Prize?

Our catalog has Stockholm Junior Water Prize open to high school students in grades 9–12, unconfirmed against the program's own page — check it before you rule yourself in or out, since eligibility is often narrower than a grade range suggests (age floors, "must have completed" rules, enrolment status).
