A strategic project for the safety of Lake Resia: the doubling of the gates for the second relief spillway of the San Valentino Dam in Bolzano.

As part of the project initiated by Alperia ATB Riva Calzoni provided a turnkey supply of two wheel gates, engineered to ensure maximum reliability and ease of maintenance.

The civil works were carried out by Semat – Civil Construction and Industrial Services, part of ATB Group – which handled the foundations and all the civil structures.

To guarantee smooth operation even under the harshest winter conditions, we integrated an advanced anti-icing system to keep control mechanisms ice-free, protecting both the equipment and the structure.

With this intervention, Lake Resia is now better prepared to face extreme weather events and ensure a controlled water flow in every season.
