Work on the Piora portal on the Ritom site is currently suspended. By the end of March, when the winter break is expected to be over due to the weather, the construction work on the portal will be continued.

The outside work on the central, equalizing basin and outlet structure in Piotta (1001 meters above sea level) as well as the excavation work on the Stalvedro window gallery are continuing. At GALPI, injection work is in progress to improve the rock.

Further information on the project can be found on the reference sheet.
