New Solution for Sewer Pipeline Rehabilitation in Szczecin
Szczecin is the seventh largest city in Poland, located about 120 km north-east of Berlin on the River Oder estuary, and has one of the biggest ports on the Baltic Sea. The contract for rehabilitating 47.6 km of sewers running under 52 city streets was signed by the consortium PBG S.A. and Diringer &, Scheidel Rohrsanierung GmbH &, Co. KG in December 2004. Rehabilitation had proved necessary because the old brick sewers and concrete pipelines built in 1904/1905 and the 1930s had become considerably damaged with cracks, corrosion and infiltration. In fact, some of the pipes were no longer capable of bearing loads and in danger of collapsing. Having carefully inspected the state of the sewers, the contractor recommended GRP pipes and sections as being the most suitable material for rehabilitating the circular and non-circular interceptors. HOBAS Products’ corrosion resistance, low weight, high structural load capacity and easy installation convinced the contractor straight away and the HOBAS NC Line® Experts’ wealth of experience helped the designers to find the right shape for the sections and the appropriate wall thickness.
