Hazen and Sawyer



About Us

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.

If you have a water engineering challenge, Hazen and Sawyer has your solution.
