Stadtwerke Flensburg GmbH operates a drinking water siphon through the Flensburg Fjord in the area of the harbour. This important main supply line was manufactured from PE 80 in the 1970s and flushed into the bottom of the fjord. The fjord pipeline runs 1,240 m from the Ostseebad waterworks in an elongated arc to a bank path on the north-east bank. Due to the location of the siphon, it was difficult to construct a new building for economic and temporal reasons. To ensure the supply of drinking water, the responsible persons opted for preventive maintenance of the pipeline section and to rehabilitate it using relining technology. The rehabilitation system used was to pass through bends of up to 30 degrees, in accordance with the requirements of the client, and to withstand an operating pressure of up to 10 bar.
