NYC awards CSO tunnel supervision

Newtown Creek CSO Partners is a joint venture comprising AECOM, Parsons Corporation and EPC Consultants Inc., and AECOM published a project announcement on March 16, 2026. (investors.aecom.com) The project design calls for a roughly 3.26-mile tunnel reaching depths of about 80–130 feet with a planned storage volume of approximately 50 million gallons. (nyc.gov) Diversion facilities at the four largest Newtown Creek outfalls will route wet-weather flows into the tunnel, which includes a tunnel dewatering pump station (TDPS) and a discharge connection to the Newtown Creek Wastewater Resource Recovery Facility. (nyc.gov) The project stems from the NYC–NYSDEC CSO Order on Consent (2005) and the Newtown Creek LTCP approved by NYSDEC in June 2018, with a DEIS Notice of Completion on September 5, 2025, a public hearing held January 7, 2026, and a Final Environmental Impact Statement issued February 5, 2026. (dec.ny.gov) City capital-project records list the tunnel budget in the multi‑billion‑dollar range (Databook shows a $3.421 billion budget figure), and journalism and procurement reporting have cited roughly $3.3 billion as the project cost; industry coverage notes a target completion stretching into the late 2030s–2040 (Smart Water cites 2040). (databook.nyc) (spartnerships.com) (smartwatermagazine.com) Members of the supervising joint venture publish digital‑delivery and asset‑management platforms—AECOM’s digital twin offerings and Parsons’ Paradim cloud asset solution—that provide BIM‑linked, cloud-hosted asset data, real‑time monitoring and lifecycle workflows typically used to integrate telemetry and IoT feeds on large water infrastructure projects. (digital.aecom.com) (parsons.com) The procurement trail shows the construction‑management solicitation listed under PIN 82626P0004 with publication on August 26, 2025 and a proposal due date of September 30, 2025 via NYC PASSPort.
