About us
Since 1951, Hazen and Sawyer has focused on two things: providing safe drinking water and controlling water pollution.
Our range of services encompasses the planning, design, and construction management of water and wastewater-related projects – from clean water treatment, storage, and distribution to wastewater and stormwater collection, treatment, and reuse.
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 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.

Achieving stable nitrogen removal while uncovering millions in potential cost savings? That’s a pretty amazing project outcome. And it’s a result that the Los Angeles County Sanitation Districts (LACSD) has demonstrated with great success at its A.K. Warren Water Resource Facility, unlocking exciting opportunities for other wastewater plants to do the same. How did the team do it? By modifying the facility’s high purity oxygen activated sludge (HPOAS) system, which isn’t typically used for nitrogen removal, to a configuration called high purity oxygen Ludzack-Ettinger (HPOLE). This required no new infrastructure, maximizing the plant’s existing equipment and highlighting opportunities to significantly reduce the capital and operational costs of implementing nitrogen removal. 💡 Read more about this innovative method, its results, and its potential future benefits: https://lnkd.in/esiVev9r #allthingswater

When the Springfield Water and Sewer Commission celebrated the groundbreaking of its new West Parish Water Treatment Plant last October, it marked a generational reinvestment in water infrastructure for the region. It was also a major milestone for Hazen. More than a century after Richard Hazen's father, Allen Hazen, designed the original West Parish Slow Sand Filters, a new generation of Hazen engineers tackled the plant redesign. The replacement plant will improve treatment resiliency for western Massachusetts while resolving water quality and disinfection byproducts issues using dissolved air flotation (DAF) technology. Plant operations will continue throughout the construction process. ⛲ Learn more about the history of this project and the benefits of this new state-of-the-art facility: https://lnkd.in/gJxBF8wh Photo Credit: Springfield Water and Sewer Commission #NEWWASpring #allthingswater

World Water Day 2025—recognized March 22—is highlighting one of the planet’s most precious and precarious freshwater resources: glaciers. Seventy percent of the Earth’s freshwater exists as snow and ice. As this frozen water melts, it plays an inimitable part in feeding the world’s rivers and ultimately providing drinking water to populations around the globe. Freshwater conservation is a crucial strategy for protecting public health and the planet.

Water reuse projects are often generational opportunities to positively impact communities, with benefits that spill across public and private sectors. They also often require generational investment, meaning that buy-in from diverse stakeholders is needed to actually make them happen. So how can utilities move beyond conceptual partnerships and establish concrete collaborations that can fuel large-scale infrastructure initiatives? 🤝 See how Hazen helped facilitate the working relationships that are driving exciting reuse projects in North Carolina and Florida: https://lnkd.in/gnHszSVC #waterreuse #allthingswater

Protecting the health and ensuring the sustainability of groundwater is a crucial piece of the water management puzzle. With over 44% of the U.S. population relying on groundwater as a primary water source, it is a key element of the national drinking water supply and an essential resource for irrigation and food production. This National Groundwater Awareness Week (and throughout the year) we encourage you to help bring awareness to the importance of a healthy groundwater supply for the environment and society at large. 📸 Below: A swath of land irrigated from the Ogallala Aquifer, which spans more than 174,000 square miles and holds more than 2.4 billion acre-feet of groundwater. #GWAW #allthingswater

States like Florida and Virginia may not seem like they’re hurting for water at first glance. But a variety of water challenges—the depletion of aquifers, demands of population growth, changing effluent disposal regulations, saltwater intrusion, land subsidence, and more—are fueling the adoption of water recycling strategies even in traditionally wet regions across the country. Potable reuse approaches in particular have entered the spotlight over recent years. Learn more about potable reuse and see how these practices are helping utilities solve for a variety of challenges here: https://lnkd.in/gj7WwBth #waterreuse #allthingswater

To see a sewer system consent decree terminated is rare, almost unheard of. Yet Alabama’s Jefferson County achieved this historic milestone in September 2024, when a federal judge released the county from the consent decree that had governed its sewer system for nearly 30 years. This settlement was the result of decades of investment in rebuilding infrastructure and rebuilding trust between the county and environmental advocates, both guided by a robust Collection System Asset Management Program. It is an inspirational example for other counties and cities under similar consent decrees across the country. Get the full story: https://lnkd.in/gJ6n3jrY #allthingswater
