Located at the foot of the Matterhorn at an altitude of 2,180 metres, the Stafel pumping station pumps some 70 million cubic metres of water per year. It is fed by the meltwater from the Z’Mutt glacier. The station channels this water up to the level of the collection conduit, 250 metres higher up. The pumping station has two large sand traps and a compensating basin.
