Environmental Hydraulics Group Inc. (EHG) provides engineering consulting services across Canada and internationally. Even the largest firms rely on EHG's stable team, with its specialist focus on fluid transients, to solve their most difficult hydraulic problems. EHG has a solid track record of technical excellence in resolving complex challenges faced by the public, mining and energy sectors when dealing with environmental and hydraulics issues:

Alan Fok, Ph.D. (Water Hammer), P.Eng. , was designated by PEO as a "Hydraulics Specialist" in 1983 for his contributions to the field of hydraulics and transients. He subsequently completed his Ph.D. and founded EHG over 15 years ago. Alan's opinions are backed by 30 years of experience in consulting, project management and advanced research. Alan has authored over 30 technical papers and developed or contributed to many analytical tools.

Sheldon Zemell, Ph.D. (Wave Propagation) has 30 years of experience with simulations of hydraulic transients, seismic response and risk. Sheldon's decade-long association with EHG has led to the solution of several intractable problems. He has developed computer models for transients, risk, water demand and power generation scheduling.

Jean-Luc Daviau, M.A.Sc. (GIS), P.Eng., has over 10 years of experience interfacing hydraulic and hydrologic models with statistical post-processors, databases and geographic information systems (GIS). He has unique expertise investigating surge-related breaks and improving hydraulic efficiency in plants and networks using advanced pressure and flow measurements. A bilingual technical writer, Jean-Luc manages projects and delivers training worldwide.

Shelley Kuan, P.Eng., has over 10 years of experience in modeling and design of hydraulic structures (physical and numerical models), sewer and water networks and river systems. Shelley has particular expertise in water disinfection using reservoir mixing models backed by field tracer tests. Shelley is an expert highway and urban drainage designer.

Who are we?
We are hydraulic engineers and applied mathematicians with advanced scientific methods, test procedures, modeling technologies and a can-do attitude. With a 15-year track record of innovations and successes, we contribute the best available expertise to solve your toughest hydraulic problems. We have multi-sector expertise in open-channel and piping hydraulics and our specialty, hydraulic transients (e.g. waterhammer). Please read-on to see how we can collaborate to meet your goals...

Who are you?
Whether you are a long-time client or just curious, chances are you and your organisation can benefit from EHG's services:

For front-line workers or plant operators: EHG saves lives and jobs. We save lives in pre-start reviews by ensuring that transients (such as waterhammer) will be controlled safely during normal or emergency operations.

We investigate industrial machinery breaks to explain the causes and help prevent future breaks. We save jobs by training you and empowering you to maximize safety and plant productivity every day: something for which a computer program is only a tool. Due to our expertise, we also routinely identify ways to help processes and plants run more efficiently, which helps companies increase revenue and avoid job cuts.

For production managers and supervisors: EHG helps you get the most out of your plant. No process can function without adequate transport, solids combination/separation and reaction/contact times. We identify hydraulic bottlenecks and transient risks to improve day-to-day efficiency while minimizing the risk of equipment breaks and interruptions to production due to transients.

Waterhammer can cause pressure cycling and fatigue or even sudden failures due to overpressures during emergency conditions. By focusing on the constraints imposed by piping and equipment characteristics and control system algorithms to identify hydraulic bottlenecks, we help you bridge the gap between management's production targets, workers' limited time and energy - and everyone's safety concerns.

For management and finance directors: EHG maximizes your shareholders' return on investment. Everyone wants an efficient and injury-free plant to guarantee predictable, reliable and high-quality production. EHG's track record with peer reviews, break investigations and plant optimizations (pre- and post-construction) ensures that improvements in productivity and safety can be identified for your plant.

Our approach is successful because it involves your organization's best resource: its people's experience and focuses it on the verifiable physics of hydraulics which are fundamental to an efficient and safe process. We help you leverage your investments in knowledge and infrastructure using our specialist skills and multi-sector experience.

You and your organization deserve to break-through to the next level of safety and productivity. Please contact EHG to find-out how we can help.
