Mark has over fifteen years of experience in water-related engineering, with a specialist emphasis on water treatment (drinking water, stormwater, mine water and wastewater) and the assessment of effects associated with the discharge of the treated water into the environment.

With recent project experience varying from drinking water upgrades (filtration and UV disinfection), leachate management and treatment, and design of mine water and municipal wastewater treatment plants – from locations within Canterbury through to outback Australia and South Africa; Mark is able to draw upon his wide breadth of knowledge and expertise to provide his clients with a holistic service to manage project risks.

Mark also has a particular interest in the field of turbulent mixing and dispersion of pollutants in rivers and from ocean outfalls. He has been involved in several dye dispersion and numerous numerical (CORMIX) studies of treated water and thermal discharges into water bodies, and the assessment of the potential effects of these discharges on the environment.

In several recent high-profile projects, Mark has been called upon by his clients to provide expert evidence at Council and Environment Court hearings in relation to their proposed projects and possible environmental effects.
