As part of the The Dewatering Institute‘s commitment towards knowledge sharing, TDI is developing a series of monthly interviews of industry leaders and professionals from different parts of the world.
Niel Kriel, appointed as TDI Advisory Council Member, operations Hydrogeologist at Rio Tinto, Perth, Western Australia, brings a wealth of knowledge and a global perspective to his new role on TDI’s Advisory Council.
With a strong foundation in hydrogeology and a focus on dewatering and groundwater management, Niel’s career spans multiple regions, from Africa to the Middle East, and now Australia. His commitment to environmental stewardship and operational efficiency aligns with TDI’s mission to promote knowledge sharing and industry advancement.
Can you tell us more about your work history and how you got into the dewatering industry?
My journey in dewatering started as ageology vacation student in Zambia’s Copper Belt, where I first encountered groundwater and mine dewatering. After completing my undergraduate studies in geology, I pursued an honours and master’s in hydrogeology while gaining hands-on experience through hydro and geophysical investigations. I then took on a role in Qatar as a dewatering design engineer, which exposed me to extensive dewatering work during the country’s rapid expansion. After moving to Australia, I became a consulting hydrogeologist, supporting dewatering projects around Perth. Today, as an operations hydrogeologist in the Pilbara, I manage in-pit dewatering and groundwater operations. Each location and aquifer system has brought unique challenges, from managing drawdowns to navigating regulatory restrictions.
What are your favourite projects that you’ve worked on in your career?
Each project has contributed to my professional growth in its way. A few standouts include Al Sa’ad Plaza in Lusail, Qatar; the ECU City Campus project in Perth; and my ongoing work with the Greater Nammuldi project.
What are some of the biggest challenges you’ve seen in the industry?
One consistent challenge is the accountability and management of dewatering discharge. Regulations around water discharge are increasingly strict, affecting where and how much water can be safely discharged. Every project must navigate this landscape, often requiring innovative solutions.
How have you seen the industry develop over the past decades?
While I haven’t yet observed decades of change, I’ve seen the field evolve to emphasise hydrogeological insights. The approach has shifted from simply drilling and pumping to conducting detailed investigations that predict system responses more accurately.
How do you see technology playing a part in the industry in the future?
Dewatering is well-positioned to benefit from advancements in technology. Today, we can monitor bore output and groundwater levels in real time, often from remote locations. This data integration enables dynamic modelling and forecasting, and I expect these tools to become even more sophisticated, further enhancing efficiency and response times.
Why would you recommend younger generations a career in the dewatering industry?
Dewatering is a universal field—whether it’s constructing infrastructure or mining, water management is essential. The industry offers diverse opportunities and attracts like-minded professionals who thrive on overcoming technical and regulatory challenges.
What aspects of the industry do you think need improving?
I’d highlight the need for better knowledge sharing and engagement across the industry. These improvements could help streamline operations and reduce repetitive challenges.
Why do you think TDI is important for the industry, and how can it help the industry develop?
TDI provides a platform for professionals worldwide to exchange ideas and solutions. Challenges that one team faces today may have been solved elsewhere. TDI’s commitment to facilitating this exchange strengthens the industry and helps all of us move forward.
What was the greatest encouragement someone gave you regarding business?
“If you don’t know, ask.” This advice has guided me through many projects and continues to encourage a mindset of constant learning.
What is your life motto?
Question everything. The very foundation of science is to keep the door open to doubt – Carlo Rovelli.
This curiosity has been essential to my work.
As a participant of the TDI Awards judging committee, what are your impressions of this year’s entries? Do you think businesses benefit from participating in such events?
The entries showcased impressive innovation, with many projects prioritising reduced impacts and improved performance. It was inspiring to see the focus on supporting young engineers and scientists. Events like the TDI Awards not only highlight individual achievements but foster the mentorship and knowledge sharing crucial for our industry’s future.
