Amiblu renovates NC sewer in Essen, Germany

In the middle of a residential district in Essen, Germany, an aged sewer has been relined with 180 m Amiblu NC Line egg profiles in merely six weeks. Traffic and citizens were not affected by the installation works.


Poor structural condition, insufficient flow capacity: These two properties of an old sewer made it clear for Stadtwerke Essen that a renovation was necessary. Initial thoughts about a completely new construction were quickly dropped in favor of a more effective relining rehabilitation. And it was Amiblu NC Line to prevail as pipe material: With the high structural strength at small wall thickness and corrosion as well as abrasion resistance, the new pipeline guaranteed an optimal flow rate combined with a very long, low-maintenance service life.


In order to reconstruct the partly curved old channel and exploit its height and width in the best possible way, Amiblu custom-manufactured non-circular profiles in lengths from 0.5 to 3 m. The GRP segments were lowered into the aged brick sewer through one pit located in the middle of the pipeline and then transported to their final positions with a special sewer wagon. The annular space between the old and new sewer channel was filled with liquid mortar and the installation completed after only six weeks.


The client, contractor, planner, and also local residents are very happy about the professional, fast, and noiseless implementation of the project. Holger Hörnemann, Amiblu Germany GmbH: “It was a pleasure to work with such experts to achieve this great result.”


The project was optimally planned and implemented thanks to the outstanding communication and cooperation of all participants.” – Johannes Leewe, Aarsleff Rohrsanierung GmbH, Contractor
