Electricity from drinking water

Did you know? We supply the city of Chur with around 80% spring water and 20% groundwater. We obtain around 95% of the spring water from springs in the Parpan and Valbella area. On the way between Parpan and Chur, we use the water to produce green electricity five times over – always using the same principle: the water keeps a turbine turning, which then drives a generator to produce electricity.

10,655 m³
is the total capacity of our eight reservoirs
The spring water falls 900 meters between Parpan and Chur
12.5 million liters of water are used on average every day
Our water supply network is 260 km long

How does electricity production with drinking water power plants work?

It’s quite simple: spring water from higher elevations flows through drinking water pipes into the lower reservoirs. The difference in height creates a lot of energy in the pipes. In the past, the pressure was eliminated using shafts. Today, we drive turbines to produce ecological electricity.
