Sewer Line Repair & Hookups in West Islip, NYSewered, Unsewered and Next in Line

About 73% of the hamlet's area is in Suffolk County Sewer District 3, by our overlay of the county's map. The Long Island Commission for Aquifer Protection says the district was approved by voters in November 1969 and that its Bergen Point plant went online in October 1981. Suffolk Public Works says problems inside the building or between your house connection and the main aren't the county's responsibility, so the lateral is the owner's. With 65% of West Islip homes built in the 1950s and 1960s, by the Census Bureau's latest survey, many laterals are clay or cast iron with roots and sags. We clear, repair or replace them. For a problem in the main, the county's Sewer District 3 emergency line is (631) 854-4150.

The county's 2025 Subwatersheds Wastewater Implementation Plan lists a project (CP 8518) to sewer an area north and east of Arbor Street and Kime Avenue, with about 518 residential connections and construction completion scheduled for December 2028. When the main reaches your street, the house side of the hookup is typically:

• a new line from the house to the street connection, at the right depth and pitch;
• rerouting the house drain to leave toward the street, if it now exits toward the backyard cesspool.

We do both. Taking the old cesspool out of service is cesspool work for a separate contractor. If your line to the cesspool is failing before the sewer arrives, it has to be fixed now; we can plan that repair with the future hookup in mind.
