Achieving water quality and quantity objectives with practical, forward-thinking solutions that return lasting benefits.

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

    “New plants that serve populations this size are generational investments, and we don’t see that every day.” Springfield Water and Sewer Commission in Western Massachusetts, one of our oldest clients, just released this inspiring video about their new West Parish Filters Water Treatment Plant featuring Kristen Barrett, lead engineer, and Mr. Allen Hazen himself, designer of the original 1905 plant! This is a story 100 years in the making and we couldn’t be prouder to help write this new chapter in Springfield history. https://lnkd.in/g_9t4vPZ

    Wouldn't it be nice if you could destroy PFAS in biosolids AND generate net-positive energy ⚡ in the process?    It's not as far-fetched as it sounds. AirSCWO is a technology that uses supercritical water oxidation (SCWO) to remove organic contaminants like PFAS from biosolids. At a big enough scale, the process can generate enough heat to produce electricity. Hazen recently partnered with 374Water, the company behind AirSCWO, and Orange County Sanitation District to pilot this innovative technology.   Read more about the innovative pilot here: https://lnkd.in/eusETFDp

    ✔ Known: Gasification and a similar process called pyrolysis can remove PFAS from biosolids. ❓ Unknown: Where do the chemicals go after that?   In March, a Hazen-led research team collected air, solid, and liquid samples from a biosolids gasification facility in Edmonds, Washington (below). The goal? Determine whether, and where, gasification could be destroying PFAS after removing them from biosolids. The Water Research Foundation (WRF)-funded project includes Ecoremedy, LLC, faculty and students from Manhattan College and the University at Buffalo, and Mostardi Platt.   What they find could help an industry facing potential new PFAS regulations. Those results are pending—but the sampling is done. Here's what it looked like: https://lnkd.in/g8xwM7ug

    Trivia time: What contaminants could complicate how drinking water plants manage hundreds of millions of tons of residuals (waste) generated annually by their treatment processes?    Hint: Four letters that are often in the news right now 🔲🔲🔲🔲   ....   🧪 Answer: Chemicals called PFAS, or per- and polyfluoroalkyl substances. Experts from Hazen (including Conner Murray, below) and the American Water Works Association recently published a trailblazing study on PFAS in drinking water residuals. It estimated the total amount of residuals generated annually in the U.S., offered a framework for estimating PFAS concentrations in those residuals, and warned that drinking water plants could be affected by new hazardous waste rules from the EPA.    Read more: https://lnkd.in/eMtf-QSy

    🔬 Pioneering PFAS Research Underway!  Hazen, in partnership with Aclarity and The University of Texas at El Paso, is leading a groundbreaking 60-day pilot study on electrochemical oxidation (EO) technology for destroying PFAS in drinking water waste residuals. This research is taking place at the Bureau of Reclamation's Brackish Groundwater National Desalination Research Facility in New Mexico.  Key Project Goals:  ✅ Test electrode durability  ✅ Assess water quality impacts  ✅ Determine cost-effectiveness Results will push the industry forward in managing PFAS-impacted waste. Stay tuned for insights and innovations in the race to eliminate these "forever chemicals" from our water systems. https://lnkd.in/gbMYEM-Z #WaterTreatment #PFAS #Innovation #Sustainability #Aclarity #UTEP #Desalination #CleanWater #ACE24 American Water Works Association

    🙋♂️ Q: EPA's new PFAS rule means you need to choose a new treatment technology, which can take six months to a year. If you don’t have that kind of time, how can you speed up the process? 📢 A: With great modeling tools—and great experts to make sense of them. In just a month, Hazen used both to zero in on a good PFAS removal option for a client on a very tight schedule. One of the models we used was Hazen GAC. This machine learning tool can predict PFAS removal performance in days, delivering results that rival those of lab tests while shaving months off the decision-making process.

    🦀 Happy Chesapeake Bay Awareness Week 2024! 🦀   From June 1-9, we celebrate the culture, history, and beauty of the U.S.'s largest estuary, home to the iconic blue crabs. The Chesapeake Bay watershed weaves together rivers, streams, and communities across 64,000 square miles. More than 18 million of us, along with 3,600 species of plants and animals, call it home. Sustaining and restoring this national treasure is a responsibility we all share.   This week features two key events: the Patuxent River Wade-In in Maryland and Clean the Bay Day in Virginia. The Patuxent River Wade-In monitors water clarity, highlighting the health of Maryland's largest river. Since 1989, Clean the Bay Day has seen over 165,500 Virginians remove more than 7.18 million pounds of debris from our waterways.   Join us in celebrating and protecting our precious Chesapeake Bay! #ChesapeakeBayAwarenessWeek #CleanTheBayDay #PatuxentRiverWadeIn #WaterQuality 🌿💧🦀

    🏞️🚨 Today is National Dam Safety Awareness Day! This day reminds us of our shared responsibility to maintain and fortify dams, essential for water supply, flood control, irrigation, and hydropower. At Hazen, we partner with communities to ensure dam safety through construction, maintenance, rehabilitation, and emergency repairs. Let’s prioritize dam safety and protect our communities together. #DamSafety #DamSafetyDay Association of State Dam Safety Officials (ASDSO)

    After being recognized for excellence by their regional ACEC chapters, two projects supported by Hazen were recently named National Recognition winners at the ACEC National Engineering Excellence Awards – the Noman Cole PCP Disinfection Project and the NYC Cloudburst Citywide Feasibility Study. Both projects were recognized for incorporating skill and ingenuity while providing significant benefits to the public and the engineering profession.
