In the spring of 2002 Aarsleff implemented one of the biggest cured-in-place pipe linings ever implemented in Denmark.The pipeline consisted of a 124-year-old, brick built, oval sewer pipe dimensioned 1,725 x 1,600 mm. The joints of the existing pipe were crumbling and therefore the 136m long pipe did not live up to the functional requirements.The renovation was executed with a traditional water relining and the installation lasted approx. five hours. After this the liner cured for 1½ days followed by a cooling period of another 1½ days. Finally the 32 laterals to the buildings in the street could be cut free.During execution of the renovation work, Pipe Technologies established a 140m long bypass pumping that transported approx. 400 litres of water per second.
