A bit of history...
The Conza dam was built by the Irrigation Development and Land Transformation Authority in Puglia, Lucania and Irpinia, which still manages the works.
Practices are underway for the final test of the dam which will allow to reach the maximum capacity foreseen for the reservoir, equal to 435 m a.s.l.
The reservoir on the back of the dam has a capacity of approximately 64 million cubic meters, with the possibility of regulating up to 90 million cubic meters.
The retained waters are intended for drinking and irrigation use; for the latter is foreseen the return of the water in the river bed of the Ofanto downstream of the dam and the subsequent collection near the Traversa of Santa Venere followed
by the derivation works.
Overall the Ofanto aqueduct consists of:
- Intake work of the dam
- Pipeline of adduction of raw water to the water purification plant
- Water purification plant
- Storage tank
- Gravity pipeline to Canosa
The planned works will allow to treat an average capacity of 1 mc/sec, or an annual volume of 31.5 Mmc to taken from the Conza reservoir; in order to have the necessary elasticity in operation and to allow the effective treatment of the indicated
water volume (31.5 Mmc), it was also envisaged that the derivation works of the dam and the individual treatment stations of the plant are proportionate for the flow rate of 1.8 mc/s.
The maximum flow rate of 3.6 mc/s is reached during the irrigation season.
