20120230767 | PASSIVE CAPILLARY AND GRAVITY DRAINAGE SYSTEM AND METHOD - A system for draining liquid from soil is disclosed. The system includes a passive capillary drain in combination with a core for gravity flow, including a sand topdressing layer, a native soil interface, and a rootzone, a curtain traversing from the sand topdressing layer through the native soil interface to at least one tube element, the at least one tube element pulling the water out of the soil with capillary suction, and a core central to the at least one tube element that moves excess water via gravity flow with capillary suction. The elements may be installed parallel at a 3 feet center and a depth of 10 inches, and/or may be installed vertically. | 09-13-2012 |
