Andrew Hellebust, M.S.E., P.Eng.

Andrew Hellebust, President and Senior Engineer at Rivercourt Engineering, is a recognized expert in the reuse of wastewater effluent, natural biological treatments and constructed wetland design in small, communal systems. He studied chemical engineering at the University of Toronto, did research work in microbiology at Princeton University, and holds a Masters Degree of Science in Engineering. For over 20 years, Andrew has been designing on-site and distributed water infrastructures ranging from non-potable urban water systems to advanced wastewater treatment systems for remote sites. He also provides environmental assessments for soil contamination, as well as spill clean ups and remediation.

 

Andrew is a leader in non-potable and on-site sewage code regulations, serving with the Canadian Standards Association (CSA B128 committee on non-potable water systems), the International Association of Plumbing and Mechanical Officials (IAPMO technical subcommittee on Reclaimed Water Conservation Systems) and the Ontario MMAH Building Materials Evaluation Commission (BMEC). He has been the main designer for Aqua Treatment Technologies, an installer of constructed wetlands, and is Senior Engineer at Canadian Shield Consultants who are active in northern Ontario water, wastewater and hazardous materials projects. Andrew has also acted as a Research Associate with Fleming College's Centre for Alternative Wastewater Treatment, and has been a speaker and teacher at various academic institutions, including The University of Toronto. Andrew's own home design project won The Canada Green Building Council Award in 2015.

 

Long-term goals of his designs include providing water services with lower greenhouse gas emissions, maintaining a high capacity of water for ecological services within watersheds in terms of quality and availability, and optimizing nutrient and resource recovery and reuse to build soil, sequester carbon and make food production sustainable.

 

Andrew believes that, by practising sustainable design, every building or community project is an opportunity to provide clean energy and water, support nutrient cycles and maintain year round local food growth – for the benefit of healing the environment and the habitat for all life.

 

Greg Allen, B.A.Sc., P.Eng.

Greg Allen has been one of the primary proponents and most passionate advocates of sustainable design for over 40 years. He has recognized the need to reduce our reliance on fossil fuels since the 1970's and has since been a fearless voice for change. Not only has Greg been a pioneer in the area of renewable energy, but his ability to creatively envision how humanity must adapt to our changing climate has led to many award-winning and groundbreaking achievements:

 

  • Design of homes for the 1st NRCan Advanced House Project in which energy consumption was reduced by 2/3

  • Established Canada's 1st solar collector manufacturing operation, which was the first to design and produce solar energy equipment

  • Co-design of the 1st Heat Recovery Ventilator (HRV)

  • Implementation of the Deep Lake Water Cooling System, which uses Lake Ontario as a cooling resource for many of downtown Toronto's office buildings

  • Design of an off-grid, energy efficient building at the Boyne River Ecology Centre, which the Toronto District School Board uses to teach renewable energy

  • Founded the Renewable Energy Co-operative Movement, which pioneered the use of wind turbines

  • Co-founded the Ontario Sustainable Energy Association with Rivercourt General Manager Kevin Best, which led to the creation of The Green Energy Act

Greg's work is critically acclaimed and has received awards such as:

 

  • The 2008 Green Toronto Award for Leadership

  • The 2005 Lifetime Achievement Award for green building design

  • Service to the Environment Award from the Ontario Association of Landscape Architects

Professionally, Greg has acted as a Sustainable Design Strategist at HOK, President of Allen-Drerup-White Ltd. and as founding Senior Associate of Sustainable EDGE Ltd.

He now brings his illustrious background as a designer, builder, community planner, inventor, researcher, manufacturer, policy adviser, university-level teacher, community activist and environmental consultant to Rivercourt Engineering as Senior Associate. Greg hopes to impart his knowledge, to teach, to inspire, and to be part of a team that is working to make a difference.

 
 

Mariko Uda

Mariko holds a bachelor's degree in Biology & Chemistry, a bachelor's degree in Civil Engineering and a certificate in Architecture. Her advanced PH.D in Civil Engineering specialized in low-impact development stormwater management, creating a costing tool for The Toronto and Region Conservation Authority, as well as sustainable neighbourhood design which encompassed climate change adaptation and place based design.

Mariko has served as an environmental specialist and technical writer for Ontario Power Generation and as an assistant to architects at Stevens Burgess Architects.

Mariko is a holistic teacher, analyst and strategist in the fields of academia, research and community development. Her passion for the environment is evidenced not only by her teachings at the University of Toronto, but also by her extensive public presentations and volunteer activities as a community organizer.

Pratima Sharma

Pratima was raised in Nepal and obtained her Ph.D in Environmental Science from Saitama University in Japan, focusing on aquatic systems management. During that time, she also worked for a Civil Engineering and Eco Technology Consulting Co. In Tokyo as a water quality analyst. After graduation, she worked for environmental consultants in Nepal and as a guest lecturer on fresh water ecology to graduate students.

Upon moving to Canada in 2012, Pratima attended the Environmental Technician program at Seneca College, graduating with honours. She also has studied Sustainable Energy at Humber College and taken online courses from various universities and training programs in both Ontario and Nepal.

 

Pratima has co-authored several published articles on water quality. She actively volunteers for the Toronto Green Community as a Community Ambassador and recently served as an Executive Assistant through a co-op program for York University's Regenesis program.

 

Eric Rozema

Eric studied at the University of Guelph earning a a Bachelor of Science with a major in Environmental biology and then a Master’s degree in Environmental Sciences. Eric's thesis research evaluated the potential of using wetland plants to improve the treatment of greenhouse wastewater in constructed treatment wetlands, specifically focusing on the removal of contaminants that prohibited reuse. He has published multiple papers based on his thesis research as well as on constructed wetland performance in cold climates. Eric has experience working on the treatment of wastewater in several industries: landfills, wineries, breweries, vegetable farms, and greenhouses. Much of his experience has involved the use of constructed treatment wetlands and other biological systems. Eric is interested in sustainable water management, green technology, and environmental conservation.
