As of this year the board of SIWI has decided to increase the prize sum to the winners and also to institute a new prize. Crown Princess Victoria of Sweden is the Patron of the Stockholm Junior Water Prize and Xylem Inc. SAS & Coca-Cola Environment Foundation is the official supporter of the prize.

Stockholm (2014-09-03) – Hayley Todesco from Canada received the 2014 Stockholm Junior Water Prize today for inventing a method that uses sand filters to treat oil contaminated water and recover water for reuse. Sand filters have traditionally been used to treat drinking water, but Hayley Todesco instead used slow sand filters on contaminated water in oil sands tailing ponds.

The winning entry is a new application of an old water treatment technology that dates back to 1804.

Crown Princess Victoria of Sweden presented the prize at an award ceremony during the World Water Week in Stockholm.

The method proved to treat wastewater at a faster rate than typical processes, as the sand filters grow bacteria that effectively break down toxic waste.

SIWI performs research, builds institutional capacity and provides advisory services in five thematic areas: water governance, transboundary water management, water and climate change, the water-energy-food nexus, and water economics.
