The Negri Company uses floating anti-pollution dams for all its dredging work in close proximity to sensitive areas.
These dams are adapted to the sites’ constraints, and can be deployed at relatively rough sites.
Dredging of the water intake for the Cycofos power generating station
This operation for the dredging of 12,000 m3 of polluted sand allowed the piping to be laid for the water intake for an electrical power generating station.
The sand removed was treated by hydro-cycloning in order to isolate the polluted portion, which was then disposed of.
