Civil Engineering Intern - Water (Summer 2026)

Learning begins in the classroom but there’s no better place to gain real-world experience than with Stantec. Interns are an integral part of our teams, working to solve some of the world's most complex challenges.

As an intern, you’ll work alongside our experienced practitioners and with our clients and communities. This hands-on experience will equip you with practical skills, build your network, and provide opportunities that set you up for success.

Stantec is a place where you can apply your passions and collaborate with top talent on water infrastructure work that is impactful to our clients, our communities, and the industry at large. We see water in California a bit differently here—as a single, holistic system rather than disconnected networks split by jurisdictional and socio-economic boundaries. Throughout the life cycle of capture, treatment, use, reuse, and discharge, our team optimizes every facet of a water system to help communities tap into water’s full potential. Whether a project calls for planners, designers, construction managers, or facility operators, we have the right experts to provide creative, yet practical, water solutions that address our communities’ unique water needs, now and into the future.
