EDF tunnel

At around 2,000 m in altitude, in the valley of Villeneuve, a straight-lined construction indicates the presence of an underground tunnel 16.8 km in length which pipes the waters of the Doron de Termignon from Entre-Deux-Eaux and along the way captures all the torrents of the southern slope of the Vanoise massif to discharge them into the Plan d´Aval dam in the neighbouring town of Aussois. Commissioned in August 1941, the water intake of the Doron de Termignon is one of the thousands that EDF has installed in the Alps.
