KEEPING THE Water FLOWING Clean water is something that is often taken for granted and it is enlightening to find the amount of work it takes to keep the water flowing smoothly and reliably. When you do find out the level of activity and expertise needed to do this you may never turn the tap on in the same way again. I was lucky enough to speak with cofounder and director Dr. Leon Geustyn regarding the remarkable and essential GLS Consulting. WRITTEN BY DON CAMPBELL


Founded in 1989 with the key intention of providing a comprehensive and expert service, GLS Consulting has become one of the key names in water keeping all the bases covered. Having a 50% share in IMQS they have been able to further expand upon their services and offer their clients a comprehensive solution to their projects.


ur business today focusses on water and sewer system modelling and master planning,” Leon explains, “This includes areas such as water quality modelling;

risk based pipeline replacement prioritization analysis and water and sewer system asset management planning.” While being a South African company their level of expertise has attracted clients from across the globe. “We operate from a single office in Stellenbosch, South Africa,” he continues, “Serving more than thirty municipalities, including five metro’s in South Africa. Through specialist assistance to associated companies we also provide our services to clients in South East Asia, the United States of America, Holland and Turkey.” The Source Of The Company’s Strength “GLS employ highly skilled people with over half the staff having obtained tertiary qualifications,” Leon tells us, describing the sourcepool for his company’s strength, “Three of them hold PhD’s and twelve are either holding or in the process of completing Masters Degrees in Engineering as well as one holding an MBA.” With forty three staff members working for the company financial and mentoring support is provided at all levels of advanced education. Over and above this continuous high level training is provided to staff on the sophisticated technology and methodology applied by GLS and the software training courses provided by GLS are accredited for trainees to obtain CPD points. “Staff development is incredibly important,” Leon indicates strongly, “And it’s important that everyone has the necessary

qualifications and most importantly the working experience to keep our offering at the cutting edge of our industry.”

Keeping The Customers On Course GLS has a programme of continuous research, development and improvement of skills and technology that allows for state of the art and a cost-efficient service to customers. Over the years they have managed to maintain a strong position in the market with large growth potential in its niche. This has been accomplished through their ability to apply internationally competitive software supported by a very high level of expertise and experience. When it comes to implementing this expertise into a customer focus Leon believes that individual development is not only expected but strongly supported. “All of our projects are performed against a strictly controlled and detailed scope of works and quality control processes,” Leon explains. GLS is in the process of becoming ISO 9001 Compliant and they approach each of the clients through focussed teamwork, “We perform our services via a structure where the client is the responsibility of a single team with only a small percentage of their time being taken by other projects.”
