 average productivity: 400 m3/day  maximum productivity: 800 m3/day Dredging activity has been developed along three shifts, therefore 24 hours per day, using the noise reduction tool to avoid any impact on the nearby village. In the following picture we can appreciate the dredged profile (blue line) compared to the original bed of the reservoir (green line).

CONCLUSIONS Dredging activity has been concluded fulfilling the total time allowed by the Client, taking into consideration supply and installation of the equipment, preparation of the jobsite area, assembling and testing of the dredging sys- tem, maintenance of equipment, and finally the disassembly of the equip- ment, and the restoration of the jobsite area to the original situation. Selection of the dredging system demonstrated its validity to fulfil Cli- ent’s requirements, and maintenance activity was really reduced, demon- strating that DRAGFLOW pumps are really a good and cost-effective solution 624
