Abstract

Water drains off the surface freely up to a certain water level, above which the air space above the water in the drainage channels (15-17) becomes blocked off, so that the column of water in the downpipe (18) creates a vacuum inside this space, raising the level of water inside the channels. An Independent claim is also included for the drainage system.
