Major trenchless project on Sardinia realised with Primus Line®
The ageing asbestos cement pipeline, which supplies the region around Bosa with drinking water, runs for sixkilometres through a nature reserve without public access roads. The comprehensive execution of such a large-scale rehabilitation project exclusively with trenchless technology is so far the exception not only in Italy.
The dimension of this 3-million-euro project has a signal effect: Trenchless technologies for the rehabilitation of pressure pipelines are quite suitable and useful as a complete solution for comprehensive reconstruction projects. Their performance is by no means exhausted with the rehabilitation of individual, smaller critical points in the course of a pipeline, such as the crossing of a traffic route.
The initial situation
The ageing of the DN 500 water main led to frequent breaks with water leakages. The repairs repeatedly led to interruptions in the water supply. Since this is the only source of supply, the construction of a bypass was planned for the duration of the rehabilitation project.
The choice of the rehabilitation method and the implementation were also influenced by the nature of the pipe made of asbestos cement. However, the decisive factor in the choice of the rehabilitation technology was
