New York grant backs 36-inch sewer main replacement in Port Chester
(UI) — The Village of Port Chester, New York, has secured $10 million in state funding to advance Phase 3 of its sanitary sewer revitalization program, a project that will replace an aging sewer main and more than double capacity along a critical corridor.
The funding was awarded through New York State’s Water Quality Improvement Project (WQIP) grant program, part of a broader $200 million allocation announced in January by Gov. Kathy Hochul for water infrastructure projects across the state.
In Port Chester, the funding will be used to replace the existing sanitary sewer main along Boston Post Road between Olivia Street and Purdy Avenue with a new 36-inch sewer main. The upgrade is designed to significantly increase flow capacity, reduce sanitary sewer overflows during storm events and improve overall system performance and resilience.
The project is expected to support adjacent residential neighborhoods and redevelopment of the former United Hospital campus, where preliminary grading and demolition began in 2025. In addition to system capacity improvements, the sewer upgrade is intended to reduce storm-related discharges into the Byram River, a shared regional waterway.
“Thank you to Governor Hochul and the Department of Environmental Conservation for your continued support,” Mayor Luis A. Marino said. “This project remains our village’s premier, forward-looking investment that the State’s Water Quality Improvement Program is designed to support. By addressing known capacity constraints in our sewer system, the Village is protecting public health, improving water quality, and strengthening infrastructure resilience in the face of more intense storm events and the continued revitalization and redevelopment of Port Chester.”
Village officials said the sewer investment aligns with state water-quality and climate-resiliency goals, while also supporting long-term watershed health.
