What Is a Sewer Lateral?

You'll hear plumbers and inspectors talk about your 'lateral.' It's a simple idea that has big financial implications for every homeowner.

The Definition

The sewer lateral is the private pipe that carries wastewater from your home to the public sewer main, which usually runs under the street. Think of it as your home's personal on-ramp to the municipal system.

Why You Should Care

In most New Jersey towns, the lateral is 100% the homeowner's responsibility — frequently including the part under the street. Nearly all residential sewer problems happen in the lateral, which means they're on you, not the town. That's why keeping it healthy pays off.
