Hazen and Sawyer

About Hazen and Sawyer

Since 1951, Hazen and Sawyer has focused on two critical activities – helping our clients provide safe drinking water to their customers, and controlling water pollution and its effects on the environment.

We are an employee-owned firm with over 1200 people, all working to help our clients protect public health and the environment. Our primary focus is on planning, designing, and overseeing construction of environmental infrastructure – water, wastewater, and stormwater management.

Throughout our history, our mission has remained constant – provide top-quality, client-focused environmental services. To do this, we endeavor to recruit the best people, provide them with challenging, interesting, and creative assignments, and furnish them the tools they need to succeed.

As environmental engineers and scientists, we have a deep respect for public health, ecology, and the quality of life of our neighbors, both locally and around the globe. As such, we strive to provide our clients with the best, most responsible work possible: work that ensures clean, safe drinking water; sensible wastewater management; durable, sustainable infrastructure; energy- and resource-efficient facilities – the foundation for a prosperous world.

Beyond our work for our clients, we also participate in a wide range of activities that advance the science of water engineering and help improve living conditions in communities around the world. Whether with Engineers Without Borders or Water for People, or for any number of prominent research foundations, the opportunities to learn and grow while you contribute and achieve are plentiful and span the globe.

Hazen and Sawyer, an Equal Opportunity/Affirmative Action Employer, fosters a work environment low on bureaucracy and high in creativity.

“Hazen is a large national company with a "frontier" branch in Detroit. The smaller office environment provided unique opportunities to be involved with many different projects in meaningful ways. Hazen is also very open to "flex time," which is critical when a student is trying to balance classes, work, and life.”
