Where Is My Sewer Lateral

Put simply, the sewer lateral is what connects your home’s bathrooms and other outputs to the city’s sewer system. They usually run below your home, under your yard, and onto the street, where they connect to the larger communal pipe. There’s a strong chance you don’t think about the sewer lateral under your property.

How do I locate my sewer line?

Go to the city office directly or call them to see if they can tell you where the sewer line is located. Usually, they can show you where the line goes from your home to the city’s main line. If you are unable to reach the city, see if there is an interactive underground utility map of your area online.

What is a lateral sewer connection?

The sewer lateral is a buried pipe (typically 4 inches in diameter) that connects a building’s plumbing system from the foundation to the public sewer main located in the street, an alley, or an easement. Laterals carry sanitary sewage (human waste) and industrial waste.
