20080205987 | METHOD AND APPARATUS FOR CONTROLLING DRAINAGE AND IRRIGATION OF FIELDS - A method of and apparatus for controlling drainage/irrigation of a field includes laying out a network of drainage tiles, which typically may include a main line and a number of lateral lines, extending from higher elevations to lower elevations and exiting through a manually controlled main valve to a drainage ditch. | 08-28-2008 |
20100092240 | AGRICULTURAL WATER RETENTION AND REPLENISHMENT SYSTEM - A water retention structure is provided below the surface of the soil in which plants are to be grown. The soil is excavated to a depth d below the plant's root structure and one, or more, water impervious polymeric sheet | 04-15-2010 |
20110070026 | Methods and Systems to Maintain Accessibility and Integrity of Equipment Contained in Underground Housings - Disclosed herein are methods, devices and systems to maintain the accessibility and integrity of equipment contained in underground housings. The methods, devices and systems and methods of the present invention maintain the accessibility and integrity of equipment contained in underground housings by providing at least one barrier that prevents burrowing animals from off-loading displaced ground dirt or other debris into the space created by the underground housing. | 03-24-2011 |
20110188933 | WATER-STORAGE AND WATER-PURIFICATION SYSTEM - The present invention relates to a water-storing and water-cleaning system. Said system is designed in such a manner that it can be used irrespective of location. It is used, inter alia, in agriculture, in horticulture and in reforestation. Said system comprises a reservoir ( | 08-04-2011 |
20110200390 | Free Draining Seal Device and Installation Method for Mechanically Stabilized Earth Wall Structures - A mechanically stabilized earth (MSE) wall system that permits water drainage through joints while also preventing undesirable migration of backfill through joints, thus dramatically reducing or eliminating undesirable vegetation by incorporation of a free draining seal (FDS) in panel joints, wherein the FDS structure blocks backfill but permits water migration. | 08-18-2011 |
20130101351 | Base For Turf System - An underlayment layer is configured to support an artificial turf assembly. The underlayment layer comprises a core with a top side and a bottom side. The top side has a plurality of spaced apart, upwardly oriented projections that define channels suitable for water flow along the top side of the core when the underlayment layer is positioned beneath an overlying artificial turf assembly. | 04-25-2013 |
20130129420 | BERM AND METHOD OF CONSTRUCTION THEREOF - A berm to increase capacity of an existing landfill comprises a reinforced portion and backfill material. The landfill comprises a waste-receiving recess having a surface and an outer perimeter, an edge surface peripherally adjacent at least a portion of the outer perimeter, and an existing accumulation of waste within the recess having a collective top surface. The reinforced portion has opposing inner and outer surfaces and comprises structural fill material and a plurality of reinforcing members disposed therein. The backfill material has an inner surface adjacent the inner surface of the reinforced portion. The backfill material comprises contaminated fill material and is at least partially encapsulated by an impermeable membrane. At least a portion of the berm sits on at least a portion of the edge surface of the landfill. Portions of the berm are substantially parallel to corresponding portions of the outer perimeter. | 05-23-2013 |
20130209172 | Subsurface Barrier Retention System and Methods Related Thereto - A subsurface retention barrier system installed in situ to retain water in a projected root zone of one or more plants is disclosed. An apparatus and system for installing the subsurface retention barriers and methods related thereto are also disclosed. | 08-15-2013 |
