The present invention refers to a system for collecting the rain water stored in substantially horizontal slabs and roofs after raining, which may produce flooding or swamping in a construction. Said system uses physical and mechanical principles which allow the same to work without an external power supply. The invention is described as a system that uses gravity, which includes a collecting concave plate having a protrusion at the lower portion thereof with an inverted truncated cone shape, this latter being assembled in a triangular-shaped base that is fixed in a predetermined area in the roof or slab; the plate has a mesh cover at the upper portion thereof; the central portion of the mesh cover has a perforation through which a tube is introduced, where the upper portion of said tube is coupled to a stopper that has a mineral carbon filter, while the lower portion thereof has a plurality of wavy perforations for flowing the liquid towards the inner portion thereof, so that a shut- off valve, attached to a plunger, is upwardly slid for allowing the liquid to flow to a shutting chamber when the water level is raised in the collecting plate; the tube is placed in a cap with a central perforation where the shut-off valve is placed and which is coupled to an outlet for forming a shutting chamber where a turbulence is generated by pressure during the water fall; said effect is useful for producing a suction and, once the water level is descended in the collecting plate, the flow is closed by the central perforation with the shut-off valve, and the descending water flow, by means of an outlet hose, generates a vacuum, which opens a torque valve located at the bottom of the chamber, the bottom portion having a perforation at the lower portion for allowing the stored water around the base of the outlet to flow by suction towards the shutting chamber and then to a nipple which is connected to an outlet hose that leads to a specific area of filtration, storage, reuse or d rain outlet; the water that may cause a flooding is drained from the roof of a construction avoiding damages to the same.
