In most cases, the homeowner is responsible for the sewer pipe that runs from the house to the public sewer main, called the sewer lateral or building sewer. The public sewer in the street is maintained by the local sewer authority, which for Elmont is Nassau County.
The Homeowner’s Part of the Line
The lateral carries all of your home’s wastewater out to the main. Clogs, root growth, cracks, and sagging sections in this pipe are usually the owner’s job to fix. That is true even when part of the pipe runs under the front yard or sidewalk.
Rules can vary, so check with the county if you are unsure exactly where your section ends.
The Public Sewer’s Part
The large pipe under the street is part of the public system. If it is blocked or overloaded, several homes on the same street may have problems at the same time. In that case, contact the Nassau County Department of Public Works.
How to Tell Where the Problem Is
- If only your house has slow drains or a backup, the problem is likely in your lateral.
- If neighbors report the same issue at the same time, the public sewer may be involved.
- A camera inspection through your cleanout can show the condition of your line and where a blockage sits.
Why Knowing the Boundary Helps
Knowing who is responsible helps you call the right people faster. It also helps you plan for repairs, since lateral work can take time and may involve digging. Some homeowners keep records of past inspections to make future decisions easier. Photos or video from a camera check can also help if you sell the house later.
