The values that mean our culture really is dynamic.

We can prove our culture is more creative, collaborative and therefore effective than traditional water systems consultancy models. It’s in our approach, our solutions and our three core values.


Integrity

We do the right thing. Always. We do what we say we will do. And we never compromise our ethics for profits.

Quality
We exceed expectations because we love what we do. We thrive on the challenge of solving problems and making a positive difference to business, communities and the environment.

Innovation
We challenge the norm, constantly. We relentlessly pursue better, more efficient, more sustainable solutions and ways of working together.

 

Our people and culture

Meet our founder Eelko, whose passion for engaging the logical left-brain with the creative right-brain to analyse and solve complex water engineering challenges is at the heart of OneStone. 

Eelko Van Der Vaart
CONSULTANT AND DIRECTOR

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.

Rhys Gustafsson
WATER SYSTEMS ENGINEER

Rhys joined One Stone Consulting in 2018, having previously worked for Murdoch University as a Research Assistant assessing the feasibility of decentralised water supply systems in regional Western Australia. He has experience in sustainable water systems planning and design, hydraulic and water balance modelling, instrumentation and control for water systems, and a range of field-testing expertise including water quality, aquifer performance testing and pipeline flow and pressure testing.

Rhys uses hydraulic modelling software for a range of applications including conducting water wammer analyses on water supply pipelines and wastewater pressure mains, hydraulic design of borefield water supply networks, pump station control system analysis, and security of supply assessments for potable water distribution systems.

Rhys enjoys developing a thorough understanding how water systems work from both a strategic and hydraulic perspective, and using modelling software to solve client’s problems.

Rhys is currently undertaking further studies in the field of Water Engineering and loves to spend time in nature – in the ocean surfing, in the bush mountain biking, or working on the family farm.
