On 28 March 2017 we organised the Bruis Breinen (Sparkling Brains) Hackathon during Water Innovation Day, for our client Waterboard Brabantse Delta. With over 30 participants we spent 24 hours in a sparkling hackathon to solve this challenge: How can we create a culture of innovation at the Water Boards? During breakfast, the participants presented their results to the board. One of the participants about the hackathon: “It was a true rollercoaster. The best ideas came up in the middle of the night, making all tiredness disappear. It was really unique to have this much time and attention for one challenge.” It was a dynamic side event during Water Innovation Day.
