💧 What U.S. city is reducing its reliance on imported water by ramping up potable reuse? 🔔 Los Angeles. As climate change intensifies droughts, LA’s reliance on imported water has grown riskier. That’s why the Los Angeles Department of Water and Power (LADWP) partnered with the Los Angeles Bureau of Sanitation (LASAN) to build a 20 mgd Advanced Water Purification Facility at the Donald C. Tillman Water Reclamation Plant. The facility will produce enough recycled water for 250,000 people—and a chance to strengthen LADWP and LASAN’s relationship ahead of even bigger joint potable reuse projects. https://lnkd.in/gTWAAmCr Pictured: The Japanese Garden at Tillman.

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.

🌎 One of the first plants in the world to operate the next-gen nutrient removal process known as PANDA (partial nitrification-denitrification-anammox), the Noman M. Cole Jr. Pollution Control Plant in Fairfax County, VA is making history. 🐼 What makes PANDA so revolutionary? It dramatically cuts energy consumption while efficiently treating nitrogen, a critical component in water quality management, using colonies of reddish-colored anammox bacteria. 💧 The plant is still refining the new system with Hazen’s help. But it has already seen promising initial savings, and the successful startup marks a paradigm shift in wastewater treatment. 💡 Check out how tapping into next-gen nutrient removal processes is creating new possibilities for energy efficiency and wastewater resource recovery. https://lnkd.in/e9zGbCNg #PANDA #Wastewater #AllThingsWater

🔮 What will the next-generation of wastewater nutrient removal look like? You don't need a crystal ball. Just checkout these two pilot projects in LA. 🌴 ⚡️ In the world of wastewater, nutrient removal tends to be an energy- and chemical-intensive profess. Next-gen approaches can reduce those costs, simplify operations, and increase treatment capacity. 💧 Hazen partnered with the Los Angeles County Sanitation Districts' (LACSD) on two innovative nutrient removal pilots—one using densified activated sludge (DAS) and another using partial nitrification-dentrification-anammox (PANDA)—to see if they could achieve low nutrient targets while saving money. 📈 The results? These new processes show promise in saving millions in capital expenses compared to traditional biological nutrient removal systems. 🌇 Learn more about how these projects are helping transform the future of wastewater nutrient removal: https://lnkd.in/eiKV46V4

❓ Can EPA’s required LCRR notifications be an opportunity to strengthen relationships with your customers? 👷♂️ Eddie Torres (below left) thinks so. As a master plumber for Denver Water, he didn't just remove thousands of lead service lines for customers of all stripes. He spent time with them in their homes and yards, helping them understand lead removal work and patiently answering their questions. 🏁 We asked utility leaders (and Torres, who just joined Hazen) how to unlock the opportunities in LCRR notification requirements. Here's what they shared: https://lnkd.in/dFqd_fUi #AllThingsWater #LCRR

As the Association of State Dam Safety Officials (ASDSO) kicks off its 40th(!) annual conference next week in Denver, CO, we're reminded that dam safety is a shared responsibility. Maintaining and fortifying dams is essential for water supply, flood control, irrigation, and hydropower. It takes collaboration and hard work to safeguard these critical—and often visually stunning—structures. One such example is the Savage River Dam in Maryland, where Hazen helped the Upper Potomac River Commission replace its gate system on an emergency schedule. The gates control 6.3 billion gallons of water used by hundreds of thousands of people. Here's to the ongoing collaboration that ensures the safety and resilience of our dams for generations to come. https://lnkd.in/eMn9SGJS #DamSafety #AllThingsWater #ASDSO

🎉 We are thrilled to share that an article co-authored by seven Hazen experts was selected as a 2024 winner of the prestigious Gascoigne Wastewater Treatment Plant Operational Improvement Medal! The award, which will officially be given at WEFTEC 2024, recognizes exciting advancements in water knowledge and practice. The article delves into how densified activated sludge (DAS) can improve sludge settleability while allowing for increasing capacity ratings of existing infrastructure, enabling utilities to get the most out of limited facility footprints. Congratulations to the authors, including Ronald Latimer, Alonso Griborio, Paul Pitt, Wendell Khunjar, Gayathri Ram Mohan, PhD, PE, Haley Noteboom, and Yewei Sun, all from Hazen, and David Jones and Melissa Meyer, PE from the Gwinnett County Government Department of Water Resources.

💧 Rethinking Water Security in a Drier World 🌵 As droughts stretch on in the western U.S., many communities will need to make the most of what’s already there. The Chino Desalter Authority (CDA) made this choice long ago, transforming contaminated groundwater into a clean, reliable supply with advanced treatments like GAC, RO, IX, and air stripping. With the more recent addition of a real-time digital dashboard, CDA is now optimizing every step, proving that innovation and smart management can secure water for generations to come. 🎥 Check out our video, featuring Hazen's own Cindy Miller and Mary Hambel, to see how CDA is pioneering sustainable water solutions that could change the game for water-stressed regions. https://lnkd.in/g7XacRu4 #allthingswater #watersupply #reuse

Customer acceptance of potable reuse: the final frontier. 🚀 From a water supply perspective, that is… As part of a potable reuse feasibility study, Rancho Water asked Hazen to gauge potential community support for the project. We interviewed key stakeholders in the surrounding community, the local government, and the water industry, and surveyed more than 20,000 Rancho Water customers. We learned that while Rancho Water is loved and trusted by its customers, a little education goes a long way in gaining public acceptance of potable reuse.

📰 🚨 New research alert! Three Hazen experts recently published a paper in Chemical Engineering Journal (CEJ) about an innovative pilot project in the Pacific Northwest. The pilot combines four advanced bioprocesses – partial nitrification, endogenous denitrification, PANDA, and enhanced biological phosphorus removal – into one advanced pilot design. Hazen’s Yewei Sun and Bryce Danker, P.E. will be presenting about this promising pilot later today at the Pacific Northwest Clean Water Association Conference in Boise, ID.
