Department of Water Engineering Technology

Water Engineering Technology student works in the field

Experienced faculty teach students to monitor, assess and protect both public health and water in the environment. Students will learn about water quality, water testing, treatment, biology and chemistry, through classroom, laboratory and field learning. Water Engineering Technology students who participate in the Co-operative work semesters average $25 per hour. After graduation, 84% of graduates are employed in a water related field with an average wage of $32 per hour.

Studying microplastics in fresh water

OC Water Engineering Technology students have teamed up with community partners to determine if there are microplastics in Okanagan Lake and municipal wastewater.

Joshua Sztanko, who hails originally from Niagara Falls, was one of the Okanagan College students who worked on the project.

“Our work involved isolating, verifying and measuring microplastics from the samples provided,” explains Sztanko, who will graduate this year. “This was a phenomenal capstone project in that it offered a real-world learning opportunity with microplastics and the chance to contribute to a study that has an impact right here in the Okanagan where we live.”

I am a professional engineer with more than 12 years of civil and environmental engineering experience. I have consulted on projects primarily located in British Columbia and Alberta with a focus on brownfield redevelopment. I have been with Okanagan College Water Engineering Technology program since 2004, and am currently the Department Chair. During my time with OC, I have taught a wide range of applied courses including hydrology, hydrogeology, municipal distribution and collection systems, surveying and environmental law. I am also a long-time member of the Okanagan Water Stewardship Council. I was elected to the EOCP Board of Directors in June 2018 and am currently the Board Treasurer.

Water Engineering - David Teasdale


My background includes more than 18 years of operational and management experience across several Class IV Water and Class IV Wastewater Treatment plants located in British Columbia and Alberta. I was the primary lead for the construction and management of the worlds largest and most state of the art Class IV enhanced membrane water treatment plants in North America from pre-design stage to completion. This 48-million dollar project presented extensive research opportunities working with various government agencies and organizations. I was also a key player in a 38-million dollar wastewater treatment plant expansion completed in 2014. My industry experience compounded with several technical and academic research projects provide students enrolled in the Water Engineering Technology Program a solid background for success after graduation.
