Parsons selected by New York for Sewer Overflow Storage Tunnel project

Parsons (PSN) Corporation announced that the company has been selected by the New York City Department of Environmental Protection, or DEP, to provide construction management services for the Newtown Creek Combined Sewer Overflow Storage Tunnel project in New York City. Parsons will serve as a member of Newtown Creek CSO Partners, a joint venture with AECOM and EPC Consultants Inc., supporting the delivery of a major underground infrastructure program designed to eliminate untreated sewer discharges into local waterways. The 16-year program represents one of New York City’s most significant wastewater infrastructure investments, addressing longstanding environmental challenges across Brooklyn and Queens. Parsons will provide construction management services for the large-diameter storage tunnel, tunnel dewatering pump station, and other structures, drawing on its experience delivering complex tunnel and sewer programs in dense urban environments. The project, which includes approximately 3.25 miles of tunnel and related facilities, is critical to improving water quality and protecting public health in surrounding communities. Once complete, the system will capture and store excess combined sewer flows during storm events, reducing environmental impacts and supporting long-term sustainability goals.
