Sorba is an alpine torrent that gives birth to the eponymous valley. It flows past the village of Rassa which counts only 63 inhabitants but boasts ten thousands visitors each year coming from all over the world to appreciate its virgin beauty. Sorba's waters are unspoiled; they are home to many species particularly sensitive to even minimal pollution. The construction of the hydropower station requires the laying of a one meter width steel pipeline along 1 km of the bank. To destroy the rocks and give space to the pipeline, it will be necessary the use of chemical compounds that will inevitably enter the unspoiled water and compromise its balance. The modification to the bank will destroy the habitat where the European Bullhead and Rainbow Trout lay their eggs.
The mini power station will be built a few meters from the Middle Age bridge of Rassa and it will produce a noise that despite the soundproofing will overpowers the 60db of the Sorba and Gronda put together. It is unlikely that the noise pollution of working engines will be considered a touristic highlight of an alpine village.
The municipality of Rassa emphasises that the mini power station design will be reminiscent of Walser architecture. Imagine to find yourself on the bridge of Rassa looking towards the peaks: today you would see little glaciers, free flowing water, a natural bank, herons and if you are lucky some deer. An alpine paradise. On that same bank will be laid a one kilometer long steel pipeline. The municipality has no Walser architecture solution for this.
