Method and apparatus for cleaning a water area, such as a lake, pond, river or a similar water basin, wherein the water basin is provided with a suction pipe system (4) arranged in connection with the lake (1), pond or equivalent and connected to a dredging apparatus working under water, by means of which the sludge or similar waste produced or at least part of it is passed into a suction pipe (4) and through it further into a sedimentation basin (8), where the flow is retarded so that, as it advances through the basin, extra humus and sludge material is separated from it via sedimentation, and that the water thus purified is passed back into the water area, e.g. into an inflow ditch.
