Water for Everybody!

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.

Electricity in Kandersteg

For the most of us water comes out of the tap and electricity comes out of a socket. But who knows where both are actually coming from?? We do!!

On our last Staff Night Out the Pinkies had the possibility to see all this.

Jack (UK), Pedro (PT) and Melanie (UK) finding out all where their electricity comes from

Kandersteg produces 85% of it’s electricity needs with it’s own hydro-electric power plants powered by the rivers coming down from Oeschinensee and from the Ueschinen valley.

In fact in summer Kandersteg produces more electricity then it uses and sells the excess to the rest of Switzerland. In winter, water levels are lower and some electricity has to be brought in.

Together with our guides from the Water and electricity supplier – the LWK, we saw all three power plants with the different turbines.

The oldest turbines are from the 1940’s and the newest one is from 2010.

Producing its own electricity with water has a long tradition in Kandersteg. The first power plants were built in the early 1900’s to electrify the hotels in town.

From those early days Kandersteg grew and so did the power plants.

It is quite impressive how this little village in the Swiss Alps tries to be independent and environmental friendly at the same time.

Producing electricity with water doesn’t cause any CO2 or anything dangerous for the environment.

The only thing which gets produced besides electricity is heat from the turbines. But this heat gets used to heat the LWK’s headquarters, Kandersteg Village School and the local swimming pool. Everything is taken care of… Swiss efficiency!!

A Story Of Frogs

It’s spring time at Kandersteg! After a very sunny and warm March, April is (until now) cloudy and alternates between rain and snow with a little bit of sunshine.  Even if it is quite annoying you can consider it as typical “April weather” for this region. This constantly changing weather in April is triggered by a big temperature gradient between Northern Europe and Southern Europe in spring. The air temperature tries to balance itself bringing constant weather changes in Central Europe.

Pinkie checking out the frog eggs



The frogs around the Centre don’t seem impressed by the changing weather and are happily reproducing themselves.

One lunch time we had the chance to observe them at close range around the Centre. Their behavior raised plenty of questions and lead to an interesting discussion about what they are exactly doing, where they come from and where they’ve spent the winter.

I did some research and I would like to introduce you to the secret life of the frogs.

Frogs are hibernating animals, they “sleep away” the winter and when spring arrives the animal “wakes up” again. A high concentration of glucose in the frog’s vital organs prevents them from freezing. When they wake up from their winter dormancy they migrate to their breeding sites. The female frogs lays between a hundred to a thousand eggs while the male attaches itself to the female’s back to fertilize the eggs. This position is called “Amplexus”. The male frog sits on top of the female’s back and grasps behind her front legs around her middle section. This can actually last for several days.



The "Amplexus" position



Did you know that frogs are a good sign for an intact environment? Having lots of frogs in an area tells you that the environment is healthy and complete. If for some reason frogs are suddenly missing, then this is telling us about problems in our environment. The frogs are also beneficial to humans because they eat so many insect pests. So it is an important matter to protect them.

Many frogs don’t survive the migration because there are many roads to cross. How can you help?

Make people aware that there is a place where a lot of frogs are crossing the street. In some streets there are constructions built to prevent frogs crossing these roads. In the evening people go and collect the frogs in baskets and then carry them across the busy roads.

So in conclusion the KISC frogs say “quak, quak”.
