Reconstruction and Extension of the Sewer Network in Debrecen

The second lot that was implemented with HOBAS Products was situated in the rapidly growing south-eastern part of Debrecen where a 7.5 km long new collector was established with HOBAS® SewerLine® Pipes. The diameters of the SN 10000 pipes varied between DN 400 and DN 800. HOBAS® Pipe Systems were chosen because of the products’ light weight and easy installation. The construction consortium for this project con-sisted of TEERAG-ASDAG and Swietelsky. With two successfully completed projects in hand, HOBAS Hungary is kept on the go: The construction works for the extension of Debrecen’s waste water treatment plant for which have already begun in October. Just as the proverb says, “there is no rest for the best”. After a thorough preparation phase the construction works were taken up in June 2007. The pipes’ diameters in the city center range from DN 350 to DN 1400 and have been produced with a stiffness of SN 10000. 3 m long HOBAS Pipes were used aside from the standard 6 m lengths to facilitate the installation in the narrow streets and deep trenches. Head of the construction consortium was the company Keviép and its partners were Betonút and KÖZGÉP.
