The Australian Stockholm Junior Water Prize is an annual water science competition which allows high school students to create solutions for current and future water challenges. The Prize is awarded at the Australian Water Association’s leading international conference, Ozwater’22 in May 2022 and is proudly supported by Xylem.

The winner of the Australian Stockholm Junior Water Prize will go on to compete internationally for the Stockholm Junior Water Prize. Students will travel to Stockholm during World Water Week in August 2022* to participate in the week-long cultural exchange program with national winners from over 30 other nations.*Subject to travel restrictions

2021 Winner - Annabelle Strachan, Meriden School

 


Annabelle’s study investigated the feasibility of a bio-flocculant as an accessible, safe, affordable and environmentally friendly option to reduce turbidity. Using a combination of dried lemon peel and chitosan, Annabelle tested different concentrations to find the optimal dosages to reduce turbidity. The bio-flocculant identified offered an affordable treatment option for those with limited access to clean water while being environmentally friendly and offering no adverse health effects sometimes associated with flocculation.

2020 Winner - Emma Serisier, Bishop Druitt College


Emma’s study looked at potential biowaste adsorbents to decrease the phosphate run-off into natural waterways from agricultural fertilisers and animal manures. Identifying eggshell waste as an effective adsorbent for phosphate, Emma developed a mathematical model and website for farmers to calculate cost savings and application rates of eggshell on their soils. This free and accessible tool will help farmers counteract their environmental footprint.

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

Following Macinley winning the Australian Stockholm Junior Water Prize in May 2019, she went on to take home the International Stockholm Junior Water Prize in August 2019. The Prize was presented to Macinley by HRH Crown Princess Victoria of Sweden. Read more here about Macinley's win in Stockholm
