New filter well secures water supply in Trubschachen
Strabag has installed a filter well in Trubschachen. The well was installed at a depth of 25 metres using a hydraulic cable excavator and will secure the region's drinking water supply for the next 70 to 80 years.
Strabag ‘s specialised civil engineering department has built a stainless steel filter well for the construction of a new drinking water pipeline in Trubschachen. Employees dug the borehole with a hydraulic cable excavator weighing more than 60 tonnes and 21 metres high. The well was then drilled to a depth of 25 metres, according to a press release. The installation will secure the drinking water supply for the municipalities of Trub, Trubschachen and Langnau for the next 70 to 80 years, writes the Schlieren-based construction company.
The new well location had become necessary due to new cantonal legislation. The required protection zones, particularly for areas close to roads, can now be complied with. From a technical point of view, the existing drinking water pipeline would have functioned for several more years.
The Langnau-Lucerne cantonal road is only a few metres from the existing well. “In the event of an accident, oil could get into the ground. Which is a no-go in a groundwater protection zone,” it says.
Preparations for the special construction project started in parallel with the renewal of the drinking water pipeline in the direction of Langnau, so that the new well can be seamlessly integrated.
