  • Patent number: 7857546
    Abstract: A method of and apparatus for controlling drainage/irrigation of a field includes laying out a network of spaced, interconnected water level-responsive valves coupled to 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. When the water level adjacent a valve is below a predetermined level, the valve is open allowing water to flow down to the lowest level. As the ambient water level in the soil rises, the valve's float also rises, causing the valve to close when the water reaches a predetermined level and producing a “terracing” effect wherein the rising water is sequentially stored at increasingly higher elevations for irrigating these elevated areas. Overflow conduits associated with each valve allow water to discharge into the drainage ditch when the sub-surface water level is too high.

  • Publication number: 20040175235
    Abstract: Devices and methods for streamlining the completion of work functions within a lateral pipe connected to a main pipe. A variety of different lateral devices may be used to aid in the process of relining the main or lateral pipe. A lateral location device is inserted into the lateral pipe prior to relining of the main pipe and is subsequently used to aid in the conventional cutting of the main-lateral interface. A lateral cutting device actually performs the main-lateral cutting process from within the lateral or from within the main. A lateral inspection device crawls up the lateral for inspection via camera. A lateral relining device aids in the placement of a liner used to reline the lateral pipe. Each of these interchangeable work functions may be optional performed by one or more lateral devices, often carried and inserted by a delivery device.

  • Patent number: 6709198
    Abstract: An irrigation system comprising a closed-loop piping system, a portion of which is a condensing section extending on or below ground surface, and at least another portion of which is a cool-collecting section buried under ground at a cool ground zone. The closed-loop piping holds a liquid which is propelled by a circulating system through the piping system. The liquid is chilled by heat exchanging at the cool ground zone and then flows to the condensing section where moisture from the vicinity is extracted by condensation over the condensing section. The moisture is readily available for consumption by agriculture growth.

  • Publication number: 20030077123
    Abstract: A subterranean irrigation system comprises a conduit that is attached to a soaker sheet having upper and lower permeable membranes that define a hollow interior there between. The hollow interior facilitates fluid flow there through while minimizing fluid flow resistance. The sheet typically includes a heat welded side seam along three sides of the upper and lower membranes to prevent the flow of water there through, wherein the remaining edge of the sheet is secured to the conduit. The sheet further includes a plurality of holes cut into the upper and lower membranes, wherein the hole pattern extends over the entire sheet. The holes allow the roots of grass or ground cover to grow through the soaker mat and simultaneously define channels of water flow around the holes between the upper and lower membranes.

  • Patent number: 6517284
    Abstract: A reservoir drainage system drains water away from a soil around a footing foundation of a structure and collects the drained water outside of the same. The system includes a network of drainage tubes externally rounding a perimeter of the footing foundation and connected to a collecting tube. The latter collects the drained water from the network and directs it by gravity into a collecting reservoir member located outside of the structure below a bottom level of the foundation. The drainage network has a first part that is substantially horizontally leveled and longitudinally runs along a first portion of the perimeter and generally against the same. The network also includes a second part that continues the first part, is connected to it at an upper end and longitudinally runs along a complementary second portion of the perimeter. The second part slightly outwardly diverts away and is downwardly inclined from the footing foundation down to a lower end connected to the collecting tube.
