  • Publication number: 20090175683
    Abstract: Disclosed are an even-irrigation apparatus for an underground root zone and an even-irrigation method using the same for evenly supplying water into the root zone of a variety of crops. The even-irrigation apparatus includes a plurality of irrigators buried in the entire underground root zone, to directly and evenly supply water into the root zone. Once water is introduced into a pressure-reduction valve after passing through a main pipe, limb pipe and capillary pipe connected in sequence, the water is supplied to the irrigators by way of a plurality of diverged-capillary pipes. With this even-irrigation of water, unnecessary consumption of water due to adsorption of the water into the surrounding soil except for the root zone is minimized, enabling effective irrigation of water and even growth of roots of crops. Further, even nutrition throughout the roots enables balanced growth of crops.

  • Patent number: 7273330
    Abstract: An adapter is used with a leaching chamber or like article to change the invert elevation for a pipe which carries water to the article. The first end of the adapter fits a hole or other port on the article. The body of the adapter rotates about that first end, changing the elevation of the second end relative to the base. Stops on the adapter body limit rotation: in one direction so the first and second ends are vertically aligned; and in the opposing direction so that the lengthwise axes of the first and second ends lie in an inclined plane. Thus, three positive invert elevations can be set for an inlet pipe for a particular article: a first and second at each limit of rotation of the adapter, and a third and lowermost elevation, wherein the adapter is not used.

  • Patent number: 5360556
    Abstract: An on-site wastewater treatment system distributes septic tank effluent over a particulate media filter bed through a distribution manifold at a sufficient volumetric flow rate relative to the cross-sectional area of the distribution conduits to inhibit undesirable biological growth in the conduits and in the filter by creating a scouring effect in the conduits. This effect prevents clogging of the conduits and maximizes the even distribution of effluent in the filter. A mesh fabric intercepts the downward flow of the effluent in the filter to further aid in the even distribution of effluent in the filter. Orifice shields also aid in such distribution by preventing clogging of orifices embedded in the filter media. A high pressure switch in the distribution manifold and a high water alarm in the filter pump basin indicate when required maintenance is necessary, and the switch controlling the high water alarm temporarily disables the septic tank pump as well.

  • Patent number: 4928427
    Abstract: A hollow, cellulose acetate fiber having a wall permeable to water is formed into a coil of constant dimensions. The coil is placed at the root level of the plants to be irrigated. Where the plants are spaced at intervals (as opposed to being immediately adjacent) a number of coil turns are positioned at the plant location and the coil stretched out between plant locations. In this manner, irrigation is concentrated at the plant and minimized in the intervening distance. Consequently, even though the coil is of constant dimensions and porosity, the quantity of water dispensed can be varied as desired. Similarly the spacing between parallel coils can be varied. This spacing variation is desirable where the pressure of the water varies because of height changes, on a slope for example. The subterraneon watering by coil has an additional beneficial effect because the roots of the plants tend to concentrate within the turns of the coil so as to become anchored thereto.
