A principal catch basin defining a certain storage capacity, the catch basin 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 water flow into the permeable basin to serve as a collection for sub-surface drainage. The system would include the ability to automatically pump the drainage water out using the energy of a pressurized water system in conjunction with a venturi pump without the need of any electrical sensors or signals. In addition, there may be a plurality of collection basins which could be joined together as a system to pump the water from various locations through one transport line.
