What a lateral is
The lateral is the pipe that carries wastewater from your building to the public sewer main. The part under your property is usually the owner's responsibility, and the part in the street may belong to the city, but rules vary.
How laterals are lined
A liner is installed through a cleanout or from the main, depending on access. It is cured and the connection at the main is sealed.
Cleanouts matter
A proper cleanout makes inspection and lining much easier. If you do not have one, installing one is often the first step.
Check local rules
Some cities have programs, permits or inspection requirements for laterals. Ask your contractor and your city about the requirements.
