  • Patent number: 7661904
    Abstract: Rainwater collected from roof gutters is poured into the vertical portion of an “ell” shaped perforated drainage pipe. The horizontal leaching pipe portion of the drainage pipe discharges the rainwater into a catch basin. Water from the catch basin flows into another perforated leaching pipe that is set in the bottom of a trench. In turn, the lower part of the trench is filled with crushed rock to a height of about three quarters of the trench depth. A water impermeable barrier of asphalt shingles or thirty pound asphalt roofing felt is placed over the top of the crushed rock and the balance of the trench is filled with soil up to the ground level.
