The American Council of Engineering Companies (ACEC) of New York recognized three Gannett Fleming projects at the 49th Annual Engineering Excellence Gala, held March 19, 2016.
In the Energy category, the Great Neck Water Pollution Control District’s (GNWPCD) Microturbine Cogeneration Facility (MCF) in Great Neck, New York, was awarded a Platinum Engineering Excellence Award. The project team creatively applied two emerging technologies to design an MCF that powers a 5.3 million-gallons-per-day wastewater treatment plant. By combining cogeneration, also known as combined heat and power (CHP), with the use of microturbines—a relatively new technology for the generation of electric power, GNWPCD is able to recover waste heat for sludge heating and power its plant buildings. The process delivers one of the most efficient heat and power generating systems available and introduces a combination rarely seen in the wastewater industry. GNWPCD’s 130 kilowatt CHP system produces an energy efficiency rate of 80 percent, which translates to an attractive $110,000 annual savings in utility spending. Additionally, the MCF’s roof is outfitted with 13 kilowatt solar panels. This renewable source of energy offers a cost-effective, low-maintenance, natural, and reliable source to offset the energy demands of the plant.
A Platinum Engineering Excellence Award in the Waste and Storm Water category was given to the Village of Northport Phase II Wastewater Treatment Plant (WWTP) Upgrades project in Northport, New York. An estuary of national significance, the Long Island Sound is home to an array of plants and animals, and a major source of food and recreation for more than 8 million people. Point source discharges from surrounding WWTPs have become a critical environmental issue, causing an unhealthy increase in nitrogen and a corresponding drop in dissolved oxygen levels in the Sound. To reduce nitrogen in its effluent, the Village of Northport made significant upgrades to its WWTP, which discharges into the Northport Harbor and flows into the Sound. The project cornerstone, a deep-bed sand denitrification and filtration system and associated methanol supply system, provides for the growth of bacteria to consume unwanted nitrogen. Thanks to the project, Long Island’s Centerport Beach was able to be reopened following a five-year closure.
The Sewer District No. 21 State University of New York (SUNY) Stony Brook Wastewater Treatment Plant Improvements in Stony Brook, New York, was awarded a Gold Engineering Excellence Award in the Waste and Storm Water category. This project also focused on reducing nitrogen in the Long Island Sound. To address this critical problem, the Suffolk County Department of Public Works turned to Gannett Fleming to seamlessly incorporate nitrogen removal upgrades to the WWTP without interrupting its daily operations. These improvements maximized the performance of existing treatment facilities and included the installation of a new denitrification filtration process to optimize nitrogen removal and ensure compliance with the new nitrogen permit limits. In addition, increased plant flow and loading capacity accommodated the SUNY Stony Brook University Master Facilities Expansion Plan to the year 2025.
The ACEC New York Engineering Excellence Awards are presented to projects that encompass both the public and private sector in the following categories: studies, research, and consulting services; building/technology systems; structural systems; surveying and mapping technology; environmental; waste and storm water; water resources; transportation; energy; industrial and manufacturing processes and facilities; and special projects.
Each year, over 60 member firms submit projects that are judged on a rigorous set of criteria, which includes complexity, innovation and value to society. These projects are judged by a panel of industry experts, which includes military and government officials, ACEC National and International leadership, educators from colleges’ and universities’ engineering departments, and leadership from other organizations dedicated to the built environment.
