The Kläffer Spring - Water for Vienna

Every day, up to 217 million litres of water are transported from this spring in the Styrian Salza Valley to Vienna, overcoming an altitude difference of 360 metres in 36 hours.

The Kläffer Spring is one of Europe's richest drinking water springs. It rises at a distance of 14 kilometres from Wildalpen in the Styrian Salza Valley, on the northern slope of the powerful Hochschwab Massif.

In the winter months, the yield of the spring is small. But in spring, with the thawing of the snow, a staggering 10,000 litres of water per second gush from the mountain, equalling 860 million litres per day. During this period and after heavy rainfall, lovely waterfalls attaining a drop height of up to 70 metres form along a section of 300 metres near the spring.
