Sewage Project Designed to Renaturalize the Area and Serve 2.2 Million People (Video Case Study)

The River Emscher was considered a "cesspool of the Ruhr": an open channel, extremely polluted with wastewater from coal mining and heavy industry and the feces of local residents.

HerrenknechtAG, a construction company specialized in building tunnels, was then assigned a major sewage project in the area:

10 Herrenknecht-TBMs were used to build an efficient underground pipe and tunnel system that carries the wastewater from a catchment area of 865 square kilometers and around 2.2 million inhabitants to the three central wastewater treatment plants.

This video case study explains the process in its entirety.
