In the paper the solution applied in Hamburg in the process of extending waste water treatment plant was presented. Due to limited space available the second part of the waste water treatment plant was built on the other side of the River Elbe. The waste water is transferred there by the siphon tunnel made of reinforced concrete. In order to ensure the safety of the construction the designers suggested the installation of the siphon tunnel in impermeable soils, which required its installation around 80 meters below ground surface. In contrast to the solution applied in Czajka where two GRP pipes are placed in the tunnel, in Hamburg waste water is transferred by the whole reinforced concrete siphon tunnel cross section. The good quality of the siphon tunnel project carried out in 1986 is confirmed by its trouble free operation for 34 years.
