Pumping station at the Lej Alv natural reservoir

Pumping station as event location

The pumping station can be used as an event location for corporate or private events and offers a unique atmosphere, located in the middle of the skiing and hiking area Corviglia. This exceptional location is ideal for small events such as a standing aperitif. The catering, which can be booked individually for the event, is provided by the catering establishments on Marguns, which also belong to Engadin St. Moritz Mountains.


Technical Visits

Engadin St. Moritz Mountains also offers technical visits to the pumping station located under the Lej Alv natural reservoir in order to show interested parties the high level of technical development in the high alpine management of mountains. The offer is primarily aimed at organizations and experts in the context of major events in the field of snow sports, at developers and operators of mountains used for tourism, and at resort developers and operators. However, people interested in individual technical topics can also book a guided tour and learn a lot about technical snowmaking, water management, piste creation, mountain railroad and life cycle management. The guided tour is ideal for groups between 6-20 people.
