Fiastra Dam (Macerata – Italy): supply of monitoring instrumentation

The lake of Fiastra is the largest hydroelectric reservoir in the region of Marche and was built in 1954.
Today the lake carries out, besides its hydroelectric function, an important tourist role thanks to its position between mountains and woods.
The lake water, fed by the Fiastrone River, is conducted by means of derivation works in the Valcimarra power plant where it is swirled and released into the Borgiano Basin.
These works allow the connection between the Fiastrone and Chienti sides.

The Fiastrone tank has a total capacity of 20 million cubic meters and a useful capacity for production of 16 million cubic meters.
The barrier is of symmetrical gravity arc type in reinforced concrete; the height of the crowning varies according to the riverbed from 82 to 87 m and its development is equal to 254m.
Its altitude is 650 meters above sea level .

In June 2018 Pizzi Instruments signed an important “framework agreement”, with a three-year duration, for the supply and installation of monitoring equipment for the dams managed by Enel Green Power SpA.
With reference to the framework contract signed, Pizzi Instruments receives the order for the supply of monitoring equipment for the Fiastra dam; the supply includes among its most important instruments as the automatic laser coordinometer LAC 3000, together with the direct and inverted pendulums, which are really important instruments for the monitoring and control of translations and rotations in large structures as the dams are.
The supply was successfully completed, obtaining the certificate of regular execution of the works.
