Global infrastructure firm Gannett Fleming announced today that Greg Bowden, Ph.D., joined the company as its national wastewater process leader. In this role, he is responsible for delivering advanced wastewater planning and process technology to the firm’s municipal, utility, regional authority, and industrial clients across the U.S.
“Dedicated to lifelong wastewater learning and research, Greg brings tremendous technical acumen to our team,” said Gene Koontz, PE, BCEE, vice president and director of the firm’s Water Business Line. “He is on the leading edge of wastewater process expertise, aggressively pursuing new and emerging technology to solve today’s concerns and prepare the industry for the future. As clients are continually charged to do more with less, and in the face of overburdened water resources, Greg is delivering new and innovative solutions for wastewater challenges, especially reuse.”
Bowden brings more than 25 years of wastewater research and process experience to Gannett Fleming. An expert in modeling and operations design for aerobic and anaerobic treatment systems, he has specialized knowledge in biological, physical, and chemical nutrient removal processes. Based in the South Plainfield, New Jersey, office, he also provides leadership support for the company’s national Water Business Line.
Most recently, Bowden managed an alternatives analysis study to identify biological and physical/chemical technology options for the treatment of high-strength filtrate at DC Water’s Blue Plains Advanced Wastewater Treatment Plant in Washington, D.C. A high-profile project, the study sought to identify the most cost-effective option for reducing the ammonia load returned to the mainstream plant, ultimately leading to the selection of the DEMON® deammonification technology and the largest facility of its type in the world. He also served as technical director for the Nitrogen Removal Applied Research Program, an initiative of the New York City Department of Environmental Protection. In this role, he led a team in the piloting of a step-feed BNR process to identify optimum operating conditions for nitrogen removal and piloting of the DEMON® process for treatment of high-strength centrate. Bowden put his technical expertise to work for the City of Toronto, Canada, for the expansion of the centrate treatment process at its Disco Road source-separated organics digestion facility. The digestion facility was implemented by the City to divert residential food waste from landfills and digest it to generate biogas for energy recovery and solids for composting and land application.
Bowden holds a Doctorate in chemical engineering from the University of Texas at Austin and a Bachelor of Science in chemical engineering from Oklahoma State University. As a contributing author to the 5th Edition of Wastewater Engineering: Treatment and Resource Recovery textbook – a widely used and industry-recognized technical resource for wastewater treatment published by Metcalf & Eddy – he has focused on bringing advanced and innovative technologies to the forefront and promoting their implementation and practice where they bring value to municipal agencies and owners of water reclamation facilities. He is member of the Water Environment Federation, a national non-profit organization dedicated to increasing the awareness of the value of water and providing a platform for water sector innovation.
