Ischgl Snow Reservoir, Austria

WALO successfully constructed a snow reservoir 2,500m above sea level for Silvrettaseilbahn AG, expanding the ski resort's capabilities for artificial snow production. The reservoir has a storing capacity of around 165,000m3 and was completed over one summer with a logistical challenge involved.

Case Study Description

Silvrettaseilbahn AG, the owners of a ski resort located at Ischgl in Tyrol, Austria wanted to expand their capabilities for the production of artificial snow.

 

WALO has constructed a snow reservoir 2,500m above sea level, with a storing capacity of around 165,000m3. This is filled mainly by natural melting water and flood water flow. The water can also be pumped from another storage tank.

 

Once the design had been agreed and drawn up, a drainage layer was applied with specialist equipment called a slope paver, followed by a layer of binder course and then a layer of Dense Asphaltic Concrete (DAC) over the slope and the floor level.

 

Finally the whole asphalt area was covered with a mastic sealing. A raised barrier, known as a berm, was also installed 3 meters underneath the crest. This berm was covered with rock fill as well as an asphalt coat. This prevents the natural looking rock fill placed in the upper 3 meters of the reservoir basin from slipping down.

 

The whole project including earthworks, pipe construction and the concrete and asphalt works was completed over one summer. Many different teams were all working at the same time on different parts of the scheme, creating a logistical challenge.
