  • 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.

    Abstract: A subirrigation system 10 includes a water-impervious member 16, and keeps water content in soil of a cultivated land 200 in a proper state for growing a plant. The water-impervious member 16 is formed into an upper opening vessel shape, and has a water reserving function. Water is fed to an inner portion of the water-impervious member 16 from a water tank 12 via a feed water pipe 14, whereby a soil portion 26 in a gravitational water state is formed. A water level 28 of the gravitational water within the water-impervious member 16 is properly controlled to a desired water level by a water level controller 18 provided in the feed water pipe 14. The gravitational water within the water-impervious member 16 controlled to the desired water level is appropriately sucked up to the soil in an upper layer in accordance with a capillary phenomenon. Accordingly, a soil portion 30 in a capillary water state having proper water content is formed in the cultivated land 200.

  • Patent number: 7572378
    Abstract: A process for irrigation involves monitoring reclaimed water, and treating it when necessary. The reclaimed water is tested with monitors to obtain results for water quality characteristics, including: pH; residual chlorine; and, sodium. These results are inputted to a computerized data handling system for data collection, storage and analysis for comparison to predetermined acceptable ranges for water quality characteristic, and to show any deviation from said acceptable ranges. Either alarms are set off or treatment occurs or both, when deviations are observed. Treatment includes a dechlorination system to correct active chlorine, and, optionally, an oxidation system. There is also a reverse osmosis step for reduction of salts, such as sodium. Other monitors may include one or more of hardness; turbidity; alkalinity; conductivity and nitrates.

  • Patent number: 7358626
    Abstract: A large number of irrigation system devices connected to a common two-wire cable can be powered and individually controlled from a central location by transmitting over the cable DC pulses of alternating polarity. Control information is conveyed by transmitting a command pulse train consisting of a series of pulses, separated by short no-power intervals, whose polarities indicate logic ones or zeros. Following a command pulse train, a selected watering station decoder acknowledges receipt of instructions by drawing current during a predetermined pulse of an alternating-polarity power pulse cycle, while a sensor decoder returns binary data by drawing current during one or the other of the alternating-polarity pulses of a series of power pulse cycles.
