Eelko Portrait

Eelko Van Der Vaart

Master of Science in Civil Engineering, Delft University, the Netherlands (specialising in Environmental Engineering and Water Management)

Leaving the Netherlands in 2005, where he developed his expertise in water management and control systems, Eelko came to WA where he applied his highly transferable knowledge and design skills to an increasingly diverse range of water management and distribution projects. In 2010, he established OneStone with the mission to support clients in sustainably managing our state's most precious resource by employing a creative, integrated approach to water system design.

Eelko's passion for water management is born out of his insatiable appetite for analysing complex problems. He loves the dynamic nature of water and the inherent complexities of water systems, which give him the opportunity to combine his scientific knowledge with his creative design and engineering skills. And when he isn't working tirelessly to find new and better ways to manage water, you'll find him indulging his other water-based passion – surfing at Trigg Beach.
