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.

Our focus brings us exceptional challenges – such as the largest drinking water UV disinfection installation in the world, upgrade of major wastewater treatment plants to reduce nutrient discharges to sensitive receiving waters, and recharging vital drinking water aquifers with highly-treated wastewater effluent, renewing a valuable resource.

Our focus also makes us home to many of the world’s most knowledgeable and experienced environmental engineers and scientists, each seeking a challenging and rewarding career while making an important contribution to the communities in which we work.

Our commitment to our clients is absolute. Our expert process groups contribute to the latest research and determine how to apply the most effective and efficient technologies to engineer solutions to your challenges. Your goals are our goals, and we offer the insight and experience needed to achieve and exceed them.

Our Vision

“…to be a successful, technically-focused environmental engineering firm specializing in the water environment, meeting the needs and exceeding the expectations of our clients and staff.”

Our Core Values

We endeavor to…

  • Perceive the Firm as more than just a business, and focus instead on the professional and technical aspects of our work.
  • Maintain the highest standards of integrity, to build trust with our clients and staff and protect our reputation.
  • Stay the course in terms of our core practice areas of water and wastewater, and broaden our services within these core practice areas, incorporating the latest technologies and sustainable solutions to meet our clients’ needs.
  • Keep bureaucracy to a minimum, to encourage creativity and give staff a sense of contribution and personal responsibility for the quality of our work and the satisfaction of our clients.

As society’s waste stream grows and becomes more complex, many wastewater treatment providers face competing priorities – having to contain costs while upgrading their process and/or operating strategies to meet regulations.

Hazen and Sawyer conducts and sponsors innovative research that links the latest technical thinking to the needs of the industry, enabling us to deliver the most practical, efficient, and sustainable solutions to our clients. We utilize an extensive network of experts, including professors and academic institutions, governmental agencies, and engineers and scientists of the Firm to ensure that we provide our clients with well-balanced perspectives and solutions.

Whether it’s researching the importance of dissolved organic nitrogen (DON) in achieving the most stringent nutrient limits, applying Integrated Fixed Film in Activated Sludge systems (IFAS) to enhance nutrient removal without expanding infrastructure, testing leading diffusers to inform the development of cost-saving designs and operating strategies, or continuing to research how to best use the industry’s most tried-and-true tools, Hazen and Sawyer continues to push the limits of technology to help providers strategically and efficiently meet their current and future effluent requirements.

As worldwide populations continue to rise and clean water sources become more stressed from both increased freshwater withdrawals and treated wastewater discharges, providers find themselves faced with limited sources of high-quality water to meet the myriad needs of society.

Since our founding, Hazen and Sawyer has advanced the limits of technology to meet the needs of providers and protect the public health. We’ve the largest DAF and UV disinfection facilities anywhere in the world, hundreds of plants ranging from 0.5 mgd to 20 mgd, and today we’re researching the drinking water solutions of tomorrow.

Whether it’s facing the growing challenge of endocrine disrupting compounds and pharmaceuticals/personal care products in our water supply, controlling corrosion and disinfection by-products in a distribution system, making the most efficient use of membranes, or assessing and managing the risks of climate change and extreme weather events, Hazen and Sawyer’s leading experts are working with top research foundations and some of the world’s largest utilities to find the most effective and efficient solutions.
