Abstract
Improvements in the land drainage system, characterized by the fact that on a waterproof bed there are filtering panels formed by a mesh enclosure or grid of appropriate material, inside which aggregates or any other material of equivalent mechanical resistance allow the passage of water through it, whose panels are in turn covered with a permeable layer of vegetal or non-vegetal earth that constitutes the surface of the land, so that this layer is perfectly supported by the panels, which allow the storage and water passage to lower collectors.
