Careful handling of natural resources is one of the basic principles in the planning of large construction projects. The Brenner basic tunnel – one of the largest building sites in Europe with 230 tunnel kilometres – is a prime example of this. To minimise environmental influences on the surrounding area, various containment measures have already been introduced by the responsible project promoter. Furthermore, different technical environmental compensatory work has been agreed with local and regional public authorities – in the Eisack Valley alone, work to a value of 50 million eurosis planned.
This includes the construction of a collection basin made from 100%natural rock for collecting spring water from an already existing sewage system in the valley. The water collection basin with a holding capacity of 18,500 m³is to be built in Aicha, Natz-Schabs (BZ), along the connecting road at the river Eisack in Spinges, a district of the township of Mühlbach (BZ).
