Kandersteg produces 100% of the needed drinking water out of the Oeschinensee. This water isn’t only good for the fishes and the tourists to have a cold swim in it, its quality is also so high, that it can be used for drinking water.

| Thirsty? Oeschinensee provides Kandersteg with delicious fresh water on tap! |
At the upper hydro-electric power plant, water is collected both to generate electricity, and to become drinking water.

| The UV light treatment process |
Two simple steps are between lake water and the refreshing liquid we get out of our taps.
The first step is a natural filter the clean the water from glacial mineral, little stones and other big dirt. Water leaves Oeschinensee through the ground - the porous bedrock filters the water before it flows out of the ground upstream of the turbines.
In the second step the water gets treated with UV light to kill all the germs. And that is it already! No chlorine or other chemicals need to be added. The water is constantly monitored for cleanliness and is consistently many times cleaner then the recommended limit.
The average use of Kandersteg is at about 1000l/hour. But per hour Kandersteg can also produce about 2500l of fresh water. So there is no danger that you ever run out of water in Kandersteg!
The overflow comes out of water fountains all around the village.
So come and enjoy one of the best and freshest waters of Switzerland.
