Patent number: 5360556Abstract: 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.Type: GrantFiled: August 7, 1992Date of Patent: November 1, 1994Assignee: Orenco Systems, Inc.Inventors: Harold L.

Patent number: 4293237Abstract: The present invention constitutes an improved subsurface irrigation and drainage apparatus and system for its use that includes at least one main pipe or line arranged to receive a water flow therein that can include a water born fertilizer and, optionally, the main pipe or line can incorporate a fan or like arrangement for injecting an air-flow therein and, as required, an airborn fertilizer. The main line preferably includes spaced cross-pieces that are joined to lateral lines or laterals and may incorporate sleeves therewith, which main line, laterals, and sleeves may contain weirs for maintaining a desired water head therebehind as appropriate, and may include slots, holes or like openings formed therein above and/or below a water line therein.Type: GrantFiled: June 29, 1979Date of Patent: October 6, 1981Inventors: Melvin J. Robey, David E. Bingaman, Arthur E. Read

Patent number: 4246305Abstract: This invention relates to drainage by use of elongated strips of such a physical structure that they allow an exchange of fluids between their core and the medium in which they are placed. The drainage strips are used by vertically placing them in wet soils to evacuate water contained in said soils by use of a pressure differential exerted upon the water due to the pressure of the soil layer over the atmospheric pressure in the interstices of the drainage structure.Type: GrantFiled: March 22, 1978Date of Patent: January 20, 1981Assignee: Solentanche-EntrepriseInventor: Henri Delattre

Patent number: 4180348Abstract: An irrigation and drainage system for cultivated fields, croplands and the like for supplying and extracting water and similar liquids through a subsurface conduit network automatically responsive to the ground water table occurring above or below a predetermined subsurface reference level near the depth of the conduit network. A plurality of elongated subsurface perforated conduit lines are located throughout the field at a uniform depth below ground along one or more ground elevation contour line or lines for outflow or inflow of water through the conduit line perforations when the ground water level is respectively below and above the predetermined subsurface reference level. Distribution boxes having an adjustable weir and supply water and excess water connections are provided for the conduit lines at each elevation.Type: GrantFiled: November 22, 1978Date of Patent: December 25, 1979Inventor: Richard H. Taylor

Patent number: 4128107Abstract: An outlet fitting construction for thin-walled, flexible plastic tubing for fluid distribution systems. The outlet fitting includes first and second outlet members that in the preferred embodiment are threadedly engaged and have aligned axial passageways. One outlet member is provided with an annular rim with a riding surface that facilitates insertion of the outlet fitting into an aperture in the flexible surface irrigation tubing. In an alternative embodiment a tube piercing member is provided that is engaged with the outlet members so that the outlet fitting may be inserted into a tube which does not have pre-existing apertures.Type: GrantFiled: March 1, 1977Date of Patent: December 5, 1978Assignee: Blumhardt Mfg., Inc.Inventor: Harold Blumhardt
