Wastewater Treatment Plant ‎Czepel
Hungary, Budapest

Budapest invested in a new sewage system. On the Danube Island Czepel, only four kilometers away from the center of the metropolis with more than one million inhabitants, a new treatment plant had been constructed. Two parallel running sewage tunnels were planned to connect the treatment plant with the district Buda located on the west bank of the Danube River. The tunnels were driven from a 35-meter-deep launch shaft near the Lágymányos Bridge toward the Danube Island. The performance of the tunnel crew and the AVN1200TB was record-breaking. The two 500-meter-long sewage channels could be completed in only 17 and 20 days respectively. The new treatment plant was put into operation in 2010.
