Sewer Expansion Grows Opportunities for Central Islip

A $13.7 million sewer expansion for downtown Central Islip has been completed, New York State Sen. Monica R. Martinez, Gov. Kathy Hochul, and local officials announced.  The project installed approximately 4,500 feet of new sewer line, which will serve the Central Islip business district with an average flow of 277,000 gallons per day.  This increased capacity is critical for Central Islip’s ongoing redevelopment and revitalization efforts along Carleton Avenue, including compact, mixed-use development near the Long Island Rail Road station, walkable streetscapes, and other public amenities.

Funding for the project flowed from multiple levels of government, including:

• $2 million from the New York Department of State’s Downtown Revitalization Initiative;
• $7.2 million from the U.S. Department of Commerce;
• $1 million from the Town of Islip IDA;
• $1.8 million from Suffolk County; and,
• $1.7 million from the Town of Islip.

"Suffolk County’s economic potential is tied to the capacity of its wastewater infrastructure,” said Sen. Martinez.  “Investing in water treatment capacity is one of the most important ways municipalities support a community’s growth, and completing the Central Islip Sewer Project will sustain and enhance the vitality of this downtown corridor.  Today is a recognition of that investment and of the collaboration between New York State and its federal, county and town partners to make it happen.”

New York State's contribution toward the expansion came through the Downtown Revitalization Initiative, which was launched in 2016 to accelerate and bolster the revitalization of downtowns and neighborhoods in all 10 regions of the state.  It aims to create vibrant centers of activity that serve as catalysts for increased local investments.  This funding highlights the critical role state-level support plays in driving infrastructure improvements and fostering community revitalization.

With work on the Carleton Avenue wastewater project now complete, residents and businesses in the expanded sewer area are encouraged to visit the Town of Islip’s informational page for details on the service and how to connect.
