U.S. Stockholm Junior Water Prize
The U.S. Stockholm Junior Water Prize (SJWP) was founded in 1997 by the Stockholm International Water Institute (SIWI) to complement the Stockholm Water Prize. The SJWP is the world's most prestigious award presented to a high school student for a water-research project.
Since the prize's inception, WEF has conducted the U.S. SJWP to send a national winner to the international competition. The 2025 USA National competition will be held June 19-22 at Washington University in St. Louis. State winners will be announced, here, the first week of May 2025.
The competition is open to all high school students in grades 9-12 who have reached the age of 15 by August 1 of the competition year, and have conducted a water-science research project.
