AbstractA principal catch basin defining a certain storage capacity, the catch basis situated below the level of the ground, having an upper level opening for receiving surface water drainage thereunto, and having side walls partially constructed of permeable geotextile fabric for allowing both sub-surface air to flow into the catch basin for providing additional water absorption by the ground, and for allowing water flow and sub-surface air to flow into the catch basin for providing additional water absorption by the ground, and for allowing water flow into the sub-surface water flow through the permeable basin to serve as a collection for sub-surface drainage. The system would include the ability to create a siphon within the system so that as water drains into the principal collection basin, the water may be automatically siphoned to a distant exit point or to an exit cylinder, so that there is a constant movement of water from the principal collection point to the distant exit point. In addition, there may be a plurality of collection basins which siphon into the principal collection basin which would then siphon into the distant exit point.
