Engineering for a better, more resilient future

Ready to help solve some of the world’s most pressing energy, climate change, and sustainability challenges? Environmental engineers are making a difference!

At Waterloo, you’ll merge your strengths in math and physics with biology and chemistry, then put them to use with the latest technology to address problems at the interface between engineered and natural systems. Meanwhile, you’ll gain two years of paid experience through six co-op work terms.

Find out how to develop food, water, air and energy systems that protect our health while also helping to protect and restore the world around us. You'll gain the skills needed to design smarter water treatment and distribution systems, clean contaminated soil, or even build a better city.

By graduation, you'll be ready for a future in energy sustainability analysis, pollution control and restoration, water resource engineering, air quality modelling, and more.

If providing solutions to pressing problems such as climate change, unequal access to clean drinking water, and global decreases in biodiversity is your passion, you’re in the right place. Lead the way to a more sustainable future with this in-demand field. Opportunity awaits!

Common questions about Environmental Engineering

What's the difference between Environmental Engineering and Environmental Sciences?

Engineering is more than advancing tech and machinery. In Environmental Engineering, you’ll create practical solutions to environmental challenges. You'll use science, math, and engineering to design systems and implement technologies that prevent or reduce pollution, improve water and air quality, and manage waste. Environmental engineers often work with other professionals to advance projects that promote environmental sustainability. With two years of co-op experience under your belt, you can graduate with hands-on experience in engineering consulting, government agencies, and technology-driven private firms. 

Environmental Sciences focuses on understanding natural processes that occur in the environment. You’ll look at how ecosystems function; how pollutants impact air, water, and soil; how climate change affects the Earth; and the interactions between living organisms, like plants and animals, and their surroundings. You'll investigate ways to protect and preserve the environment through research and analysis. With 25+ field courses to choose from, you’ll graduate with the hands-on skills needed for careers in fields including government and research, resource management, and environmental or ecological consulting. 

Both programs aim to protect the environment, but they take different approaches. Environmental Engineering is solution-focused and applies engineering principles to design systems solving environmental problems. Environmental Sciences is exploration-focused and studies natural processes to understand environmental issues and inform policy and conservation efforts. Engineers build tools and technologies, while scientists uncover data and insights to guide their use.

What's the difference between Environmmental Engineering and Geological Engineering?

If you’re invested in solving pressing environmental issues affecting vulnerable populations, Environmental Engineering may be for you. In this program, you’ll use math, chemistry, physics, and environmental engineering to model ecosystems, analyze pollution, and design sustainable solutions for mitigating and adapting to climate change, decreasing biodiversity, inaccessible clean drinking water, and more. You’ll learn to develop systems that protect human health while protecting and restoring the environment, whether that be through designing water treatment and distribution systems or building more eco-friendly cities. 

If you want to work outdoors while creating a safer world and better infrastructure, you’ll feel at home in Geological Engineering’s tight-knit community. By taking civil engineering, earth sciences, math, chemistry, and physics courses, you’ll come to understand geotechnical design, rock and soil mechanics, hydrogeology, and geophysics. You'll use your expertise in the real world to develop sustainable energy and mineral resources to ensure the safety of infrastructure, remove groundwater contaminants, and more. Plus, you’ll graduate with the academic qualifications for two professional designations: Professional Engineer and Professional Geoscientist. 

While both programs address challenges related to the Earth and environment, their approaches are different. Geological Engineering focuses on the subsurface, working from the ground down to understand and manage rock, soil, and groundwater systems. This work supports safe infrastructure and responsible resource development. Environmental Engineering overlaps with Geological in some areas, such as groundwater remediation, but generally takes a ground-up approach, designing systems that improve air and water quality, reduce pollution, and protect ecosystems and human health. Both fields contribute to a safer and more sustainable world, but they do so through different lenses.
