Trenchlesspedia Explains Building Sewer

The building sewer is usually comprised of two sections:

  1. The section of pipe between the building and the property line – This section of the sewer line is the responsibility of the homeowner. The property owner is, therefore, required to ensure that the length of pipe in this section is clear of blockages and is responsible for repairing any broken or collapsed section of pipe.
  2. The section of pipe between the property line and the public sewer – This section of the sewer line is the responsibility of the public works department and they are, therefore, authorized to perform all maintenance and repair of the sewer line within the public right-of-way.
