ABSTRACT:
A method for cleaning a water area including dredging, via a dredging apparatus, waste from the water area through a suction pipe into a sedimentation basin, generating a flow of the dredged waste from the water area to the sedimentation basin via siphonage and variations in heights of the suction pipe relative to a bottom of the water area, and converting energy caused by the flow of the dredged waste in the suction pipe into energy for driving the dredging apparatus.
