The Water Zone was funded by the Wellcome Trust, following the themes of its major initiative for 2016, The Crunch. Vinnie creates virtual simulations of equipment on construction vessels to test if they will survive real world conditions, Tam is a marine engineer who works at sea and on the docks managing the maintenance of ships, Mo is a civil engineer who builds water treatment facilities to process safe drinking water, Matt is a research engineer who studies chemical reactions to destroy pollutants in drinking water and Joe is a PhD student studying ways to protect people from flooding.
Students in the zone showed a general interest in engineering with many career based questions. This zone was the quietest out of all the June zones with just seven schools taking part, resulting in a below average number of questions approved.
