The sewer has a lower section (1) with tube (2) and base (3), and sewer pipes (4) branching off the sewer tube. A hollow-cylindrical insert (5) with base (6) is fitted into the sewer tube. The sewer base has a connection tube (7) at the top, and branch tubes (8) fastened to the connection tube. The lower end (9) of the insert is connected to the insert base via the connection tube. The ends (10) of the branch tubes away from the insert base are each fastened to a connection tube (11), and a pipe section is moved into it. The other tube ends are butt-joint to ends of the sewer pipes, and connection tubes and sewer pipes are connected fluid-tight via pipe connectors.
