Pipe Bursting in Esslingen

Stadtwerke Esslingen rehabilitated an old cast iron pipeline using trenchless pipe bursting. Compared to traditional rehabilitation methods, they were able to significantly reduce effort and costs. Due to the high requirements, they used the egeplast SLM® DCT pipe system with integrated quality inspection.

For the rehabilitation of the parallel gas and drinking water lines made of cast iron with an outer diameter of 160 millimeters each, Stadtwerke Esslingen opted for trenchless rehabilitation using the pipe bursting method. The rehabilitation
of aging cast iron pipelines often involves considerable effort and high costs. To keep both as low as possible, installation of the new pipelines using the pipe bursting method is recommended.

In trenchless old pipe rehabilitation using the pipe bursting method, a plastic pipe is pulled into the existing line. The old pipe is burst in the process and the fragments are displaced into the surrounding soil. The end result is a rehabilitated plastic pipeline with the same or larger diameter than the previous old pipe. Since this special installation technique places particularly high demands on the pipe material due to the forces involved and the sometimes sharp-edged fragments of the burst material, egeplast expressly recommends the use of protective casing pipes for this purpose.

Stadtwerke Esslingen went one step further and opted for the egeplast SLM® DCT, a pipe system with integrated quality inspection for trenchless installation. Integrated tracer wires enable inspection of the pipe system for integrity directly after installation. This means that security of supply can not only be restored relatively easily, but can also be documented beyond doubt at the same time. Stadtwerke Esslingen are very satisfied with the product.
