Long Island’s $13.7M sewer project completed, revitalizes Central Islip
(UI) — A $13.7 million sewer infrastructure project has been completed along Carleton Avenue in downtown Central Islip, marking a major step in the area's revitalization.
The project, part of New York's Downtown Revitalization Initiative (DRI), aims to support mixed-use development and create a vibrant downtown around the Long Island Rail Road station.
Governor Kathy Hochul emphasized the project's impact on local growth: “This new sewer line will unlock a host of opportunities for Central Islip, creating more housing for residents and driving economic revitalization for businesses and local communities.”
The new sewer system replaces outdated septic infrastructure, which previously limited development, especially for restaurants and multi-story buildings. The upgrade includes 4,500 feet of sewer line, with a capacity for 277,000 gallons per day. Funding came from multiple sources, including $2 million from the New York Department of State, $7.2 million from the U.S. Department of Commerce, and additional support from local and county governments.
Assembly Deputy Speaker Phil Ramos noted the project’s importance for the community: “These improvements are paving the way for new businesses, enhancing services, and ensuring that Central Islip remains a vibrant and diverse place to live, work, and thrive.”
Central Islip received its DRI award in 2018 as part of New York's ongoing efforts to revitalize downtowns across the state. Other Long Island communities, such as Westbury and Riverhead, have also benefited from similar initiatives.
