A house sewer is a sewer pipe that carries sewage from a building for immediate disposal. It is typically made of PVC or cast iron and is buried underground. The house sewer connects to the main sewer line, which carries sewage to the treatment plant.
A lateral sewer is a sewer pipe that carries sewage from a building to the house sewer. It is typically made of PVC or cast iron and is buried underground. The lateral sewer connects to the building’s drain pipes.
An intercepting sewer is a sewer pipe that collects sewage from several houses and carries it to the main sewer line. It is typically made of concrete or brick and is buried underground. The intercepting sewer is located between the house sewers and the main sewer line.
A main sewer is a sewer pipe that carries sewage from several intercepting sewers to the treatment plant. It is typically made of concrete or brick and is buried underground. The main sewer is located between the intercepting sewers and the treatment plant.
