Since the mid-19th century the River Emscher in the German Ruhr District has been used for disposing of wastewater. In the early 1990s, it was decided to replace the existing open wastewater system with a sewer system and to restore the River Emscher to its natural state.

By applying the pipe jacking method interlinking conduit sections with section lengths in excess of 1100 m are produced.
