Stockholm Junior Water Prize has been held every year since 1997 and has become a popular part of World Water Week. The 2020 edition is however entirely held online and due to Covid-19, only 29 countries have been able to arrange national competitions. It is the winners of these international competitions who vie for the title Stockholm Junior Water Prize champion 2020.

Who the winner is gets decided by a jury of international water experts who review all projects and interview shortlisted candidates. The jury can also award a Diploma of Excellence to a particularly worthy project. The winners of the Stockholm Junior Water Prize 2020 will be announced during a royal award ceremony on 25 August at 2pm CET. The Prize’s Patron, H.R.H. Crown Princess Victoria of Sweden, will then present the Prize to the winning team.

In addition, the public can also vote for their favourite project in the People’s Choice Award. This is a great chance to meet inspiring young innovators and get a sneak peek at their trailblazing ideas before (almost) anyone else. You can check out their project descriptions and videos on the participants’ own web page WaterTank, where you also find all the information you need to vote.

“Our finalists could be tomorrow’s leading scientists and we know from experience that their innovations can solve real-world problems. Many projects that started as part of the Stockholm Junior Water Prize are now being used, helping thousands of people in different parts of the world,” says Ania Andersch, Senior Manager Stockholm Junior Water Prize at SIWI.

She is also inspired by the commitment the participants show when it comes to creating a more sustainable future. In 2019 the Stockholm Junior Water Prize finalists joined forces and issued a statement urging world leaders to accelerate action on climate change. The statement received great attention and was sent to both the United Nations General Assembly and the climate conference COP 25 in Madrid. Read the full statement here.

What does it mean to get to the international final?
Finalists from the participating countries are invited to Stockholm for five days where they take part in the global conference through a variety of activities. Inside the World Water Week conference venue, a poster exhibition of all student projects will give the finalists an opportunity to discuss their projects with the wide range of conference attendees, including researchers, politicians and media. Each of the finalists is further interviewed by a jury of international experts, who decide on the winner announced at the prize ceremony.

Finalists of the Stockholm Junior Water Prize are also invited to join WaterTank, an exclusive alumni network for finalists. Through this network, finalists are able to connect and collaborate with each other as well with expert mentors and advisors from leading organizations, such as Xylem Inc., Raincoat Foundation and SIWI.

H.R.H. Crown Princess Victoria of Sweden presented the Stockholm Junior Water Prize to Macinley Butson from Australia. Macinley Butson has developed a new, novel and innovative ultraviolet sticker to accurately measure large UV exposures for solar disinfection of water. The SODIS sticker deeply impressed the jury for its ability to accurately measure the solar UV exposure required to sanitize drinking water through two innovative products built together.
A Diploma of Excellence was also awarded to Diana Virgovicova, United Kingdom, for her discovery of a New Photocatalyst to Solve Water Pollution.
