Jonen village flood protection


Extensive measures have been implemented to protect the settlement area of Jonen from a hundred-year flood. These include a fish-friendly block ramp, a sewer line crossing, flood control walls in the village centre, lowering of the stream bed, flattening the slope of the banks, and various stream bed structuring projects. HOLINGER was responsible for the implementation of the entire CHF 8 million project. The scope was from the tender to the completion of construction.
