High-pressure flushing and rehabilitation of sewers at Rosenheim Central Railway Station

Munich, Germany /

In the course of the project, the first task for THORN Abwassertechnik was to record the condition of the sewer. The next steps were the closure and insulation of unused sewers and the brick lining of the connections in the corresponding shaft structures.

The rehabilitation or partial renewal of the sewers in operation was carried out in various procedures. The technologies used here were sewer rehabilitation up to DN 1500 with winding pipe technology and annular space insulation as well as pipe lining up to DN 300 with inversion technology and hot water curing.
