combined sewer overflow technical

"Newtown Creek Combined Sewer Overflow Storage Tunnel project in New York City."

A combined sewer overflow happens when a single pipe system that carries both sewage and rainwater becomes overwhelmed during heavy rain or snowmelt and releases untreated wastewater into rivers, lakes or streets; imagine a bathtub with one drain that spills when too much water is added. Investors care because overflows can trigger cleanup costs, regulatory fines, infrastructure upgrades and reputational damage for utilities, municipalities and property owners, all of which can affect revenues and asset values.

construction management technical

"to provide construction management services for the Newtown Creek..."

Construction management is the professional coordination of people, schedules, budgets and materials to deliver a building or infrastructure project on time and on budget. Think of it as the project’s conductor who oversees planning, hires contractors, controls costs, and manages risks; for investors it matters because effective construction management reduces delays and cost overruns, protects contract margins, and preserves a developer’s or contractor’s reputation and future revenue.

tunnel dewatering pump station technical

"services for the large-diameter storage tunnel, tunnel dewatering pump station, and other structures"

A tunnel dewatering pump station is a system of pumps and pipes that removes groundwater and seepage from underground tunnels to keep them dry and safe, like a building’s sump pump scaled up for long underground passages. For investors, it matters because reliable dewatering prevents construction delays, costly repairs, safety incidents and regulatory fines, all of which can affect project timelines, operating costs and the expected returns on infrastructure or mining investments.

construction management information system technical

"utilize the DEP’s Construction Management Information System (CMIS), which the company originally helped develop"

A construction management information system is a software platform that centralizes project plans, budgets, schedules, contracts and field reports so teams can share updates, documents and progress in one place. For investors it's like a project's control panel: it improves visibility into costs, timelines and risks, helping detect overruns or delays sooner and providing clearer data to judge project health and cash-flow implications.

ocean outfalls technical

"With more than 250 tunnels and ocean outfalls around the world, Parsons’ projects span..."

Ocean outfalls are large pipes or tunnels that carry treated or untreated wastewater, storm runoff, or industrial discharge from land out into the sea, acting like a city’s long drainpipe that releases water offshore. Investors care because outfalls are tied to regulatory approval, cleanup and upgrade costs, legal and reputation risks, and local permitting or shutdowns that can affect utility bills, capital spending and the value of coastal assets.

CHANTILLY, Va., April 14, 2026 (GLOBE NEWSWIRE) -- Parsons Corporation (NYSE: PSN) announced today that the company has been selected by the New York City Department of Environmental Protection (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 (CM) 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.

“Parsons brings decades of experience delivering complex tunnel and water infrastructure programs that improve environmental outcomes and strengthen community resilience,” said Mark Fialkowski, president, Infrastructure North America for Parsons. “We are proud to support New York City on this critical project that will reduce sewer overflows, enhance water quality, and help meet important regulatory commitments.”

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. As the construction manager, Parsons will utilize the DEP’s Construction Management Information System (CMIS), which the company originally helped develop and deploy, to support efficient project delivery, coordination, and oversight.

Parsons is a global leader in critical infrastructure excellence, with more than 80 years of experience planning, designing, and overseeing the construction of complex tunnel projects throughout the world, including the Rondout-West Branch Bypass Tunnel, Kensico-Eastview Connection Tunnel, and Catskill Aqueduct Repair and Rehabilitation projects; each of these signature NYCDEP projects, in which Parsons provided comprehensive CM services. With more than 250 tunnels and ocean outfalls around the world, Parsons’ projects span the full range of challenging geologic environments, from seismically active Southern California to the Chesapeake Bay’s alluvial coastal plain to the mixed-face and hard-rock conditions found in and around New York City.
