I am an associate professor in the Department of Civil Engineering at Queen's University. I am also an Associate Editor with the ASCE Journal of Water Resources Planning & Management, and a licensed professional engineer (P.Eng.) with 15 years' research and consulting experience in municipal and environmental engineering. In that time, I have been developing decision support tools and technologies to support the water and municipal engineering community in making cost-effective decisions to design and rehabilitate water distribution systems. My expertise in water distribution systems analysis and optimization and my expertise in hydraulics has been sought by PEO, scientific advisory committees for international conferences in water distribution network modelling, and the Natural Science and Engineering Research Council (NSERC) to review scientific proposal.
I have also had the opportunity to work in the consulting industry. Before undertaking a Ph.D., I spent some time in the employ of the consulting firm R.V. Anderson Associates Limited in Toronto, Ontario, Canada. My consulting experience is wide-ranging and includes the design of drinking water, storm water, and wastewater systems, as well as infrastructure-renewal planning. I am currently a licensed Professional Engineer (P.Eng.) in the province of Ontario.

As a leading researcher in sustainable water systems, Dr. Filion is developing innovative solutions to the high energy costs and water quality problems associated with aging municipal water systems. As water systems age, they require more energy to operate. Dr. Filion is exploring ways to reduce the energy and environmental footprint of water systems. His research is intended to help municipalities deliver safe drinking water to Canadians more cost effectively and with less energy; to achieve this, he has been developing whole-of-life design approaches to optimize the rehabilitation of water main assets that will reduce energy use and the greenhouse gas emissions linked to water provision. Dr. Filion is also developing a novel energy analysis to help municipalities better understand how reducing leakage, conserving water, and rehabilitating old pipes can save energy in water systems. Dr. Filion has recently been recognized by his peers for his leading contributions to the field of sustainable water systems with a keynote lecture at the 2014 International Water Distribution System Analysis Conference. Additionally, Dr. Filion’s pioneering work in life-cycle energy analysis of water systems has also been recognized with “best paper” awards from the Journal of American Water Works Association.
Dr. Filion is also working to improve drinking water quality in water distribution systems. His research in this area focuses on studying biofilm growth and mobilization–two mechanisms that can lead to drinking water quality problems in municipal systems. Dr. Filion was recently awarded funding from the federal and provincial governments to establish a large-scale pipe research facility that will allow him to examine the influence of fluid flow and water quality conditions on biofilm growth and mobilization in pipes. Ultimately, Dr. Filion’s research goal is to help evaluate the effectiveness of new pipe liner technologies and other strategies in improving water quality in municipal water distribution systems.
WATER DISTRIBUTION SYSTEMS
Area 1: Climate Change Mitigation of Drinking Water Systems
Building, operating, and decommissioning drinking water systems has a large impact on the environment in relation to energy use and greenhouse gas (GHG) emissions. With plans for future carbon tax and cap-and-trade agreements in Canada and the US, water utilities will be expected to track and reduce their carbon emissions. This first research area is focused on developing planning, design, and optimization methods to help water utilities reduce GHG and air emissions, non-renewable energy use, and environmental releases in their drinking water systems.
Area 2: Climate Change Adaptation of Drinking Water Systems
Anticipated changes to our climate (IPCC 2007) are expected to create important changes in the water industry ranging from a possible increase in water demand to important changes to source water quality. A big challenge that municipal water utilities face is to plan the upgrade and rehabilitation of their water systems with limited information on future water demand, on future source water quality, and on the future condition of buried water main infrastructure. This second research area is focused on developing methods to design and optimize drinking water systems so that they are more resilient and adaptable to anticipated changes in climate to avoid unplanned and expensive retrofits in the future.
Area 3: Discolouration in Drinking Water Systems
Ageing water pipes cause water quality problems ranging from bad odours to 'red water' discolouration events that undermine public confidence in Canada's drinking water infrastructure. The deterioration of grey cast iron and unlined ductile iron mains can contribute iron corrosion products to bulk water and solids and colloidal particles (e.g., manganese "slimes") can accumulate on pipe walls. Discolouration is caused by the long-term accumulation of particles on pipe walls and subsequent mobilization of these particles triggered by sudden increases in flow and shearing forces. The short and medium term objectives of the research are to: (i) examine the fundamental processes of particle accumulation and mobilization in buried water mains assets found in Canadian networks; (ii) examine the effect of fluid velocity and conditioning shear stress on material accumulation and biofilm formation, (iii) examine the effect of flushing velocity & scouring shear stresses on material mobilization; (iv) establish how deteriorated pipes and repaired pipes influence water quality. In the long term, guidance will result for water pipe operation, maintenance and replacement.
STORM WATER MANAGEMENT
Area 1: Sustainable Water Re-Use for Non-Potable Applications at Residential and Community Scales
This research area is focused on investigating the feasibility of capturing and treating storm water (at the residential or watershed scale, or both) for re-use in non-potable applications such as lawn irrigation, and other outdoor municipal water uses. The feasibility of integrating storm water collection with non-potable water distribution will be examined with respect to capital costs, operational costs, source water and community protection performance (e.g., reduction in combined sewer overflows), improvements in water quality, sustainability of the urban water balance, and hydraulic and hydrologic robustness and resilience.
Area 2: Adaptation Planning of Storm Water Systems for Extreme Weather Events
Climate change impacts in Ontario have the potential to produce extreme storm events with higher rainfall intensities and larger rainfall volumes. The changes in extreme events are of particular importance to the design, operation and maintenance of municipal water management infrastructure. There is a need to understand how higher-intensity storm events will affect the performance of existing storm water infrastructure in Canadian cities. The ongoing research is directed to: (i) developing rainfall forecasting models that account for a possible climate change in the coming decades; (ii) developing distributed hydrologic/hydraulic SWMM models to evaluate the performance of urban drainage systems under status quo (no climate change) and climate change scenarios; (iii) using the information generated with SWMM models to help Canadian municipalities make changes to design standards of storm water infrastructure and to plan and implement flood protection infrastructure to protect urban areas from flooding.
If you are thinking of pursuing graduate studies in one of the areas outlined above, I would be pleased to hear from you.
