The Stockholm Junior Water Prize is the world’s most prestigious youth award given to a high school student for water research. 

In Australia, the Australian Water Association organises the national competition, with support from Xylem.

The winner of the Australian competition is invited to participate in the international competition held each year during World Water Week in Stockholm, Sweden, competing with over 30 countries in the international final.

The SODIS Sticker: Development and testing of a Film based detector system for appropriate Ultraviolet Solar Disinfection (SODIS) of Water
Macinley Butson, The Illawarra Grammar School
Macinley has developed the SODIS sticker, an innovative ultraviolet radiation sticker which accurately measures the solar UV exposure required to sanitise drinking water. This is done through a high accuracy transparent UV-sensitive film coupled with a partially UV blocking filter, which allows the SODIS sticker to measure direct UV exposure from the sun and reflected UV from other objects. At just over one cent to produce, it is also a cost-effective and safe way of purifying drinking water for developing communities
