Bunnik, The Netherlands, 23 January 2012 - Wayss & Freytag Ingenieurbau, the German tunnel specialists of Royal BAM Group, have been awarded a contract in Germany to the value of €420 million for the construction of a 35 kilometre-long underground waste water pipeline. The project is part of a large-scale modernisation of the waste water system of the Emschergenossenschaft water management association.
The project involves the construction of a pipeline between Dortmund and Bottrop, which is intended to carry wastewater to a water purification plant near Bottrop. The underground pipeline, which will be built in the form of a tunnel, will vary in diameter from 1.6 to 2.8 metres and will run parallel to the River Emscher.
The work will start next spring and is expected to take five years.
