Hunts Point WWTP New Anaerobic Digester Facilities

Project Description: This project serves to maintain stable operations for solids processing and serve as the backbone to achieve future energy and emission reductions and resource recovery goals. With four brand-new digesters, reuse of digester biogas, and sustainable roofs, the project at Hunts Point Wastewater Resource Recovery Facility in the Bronx epitomizes this mission. As an example, new digester waste gas burners enhance the quality of air by more efficiently destroying air pollutants. Replacing aging components of the treatment plant with state-of-the-art technology improves the digestion process and reduces the sludge loads requiring dewatering. This, in turn, reduces disposal truck traffic from the plant and produces less volume of dewatered sludge that must be sent to landfills.

A comprehensive sustainability management plan was developed to assess and prioritize sustainability goals across economic, social, and environmental dimensions. Specific targets were established around, for example, sustainable sourcing of new construction materials; use of recycled materials; construction and demolition waste diversion from landfills; and use of renewable energy, including digester gas produced by the facility and photovoltaic panels on the digester feed pump station and control building roofs.
