Trenchless Rehabilitation of DN 750 and DN 1000 Sewer Pressure Pipelines Poses Special Challenges
For the first time and on behalf of the Berliner Wasserbetriebe as the water supplier of Germany's capital city Berlin, the company Karl Weiss Technologies GmbH presented the fabric-hose relining technology of a DN 1000 sewer pressure pipeline with an MAOP (PN) of 10 bar made of low-carbon steel using the starline®HPL-S technology (Figure 1 and 2) in conjunction with the Exhibition Wasser Berlin International and International NO DIG Conference in May 2011. This construction project is carried out using the fabric-hose relining technology in two sections to permanently restore operational safety of two sewer pressure pipelines with a DN 750 diameter (construction section 1) and a DN 1000 dia-meter (construction section 2) with a total length of about 1300 m in Frankfurter Allee in Berlin-Friedrichshain.
