Stormwater collects at hardscape surface points , entering into surface drains that are accurately placed where the largest volume of water flows . |
Water flows through the surface drains , traveling through silt and chemical removing filters before it enters the leach field . |
Water then enters a pre-engineered water storage field of void spaced aggregate , naturally filtering the water before migrating into the aqueduct . |
As water travels to the aqueduct , it slowly percolates through a permeable lens , eventually leaching into the natural local soil base . |
