Patent number: 7661903Abstract: A drain field assembly includes a distribution pipe for receiving liquid effluent that has a plurality of holes through the wall. A plurality of generally cylindrical void pipes receive effluent from the distribution pipe, retaining the effluent for a time, and distributing the effluent to an area of soil. The void pipes are positioned in a trench atop one another so that the cylindrical axis of a bottom void pipe is substantially vertically aligned with the cylindrical axis of a top void pipe, and the cylindrical axis of a middle void pipe is offset from those of the bottom and top void pipes. A distribution pipe is positioned within the top void pipe. In some embodiments a second distribution pipe can be positioned atop the top void pipe. A protective soil-impervious, liquid-permeable sheeting is placed atop and beneath the assembly for protecting the holes pipes from intrusion by soil.Type: GrantFiled: March 26, 2008Date of Patent: February 16, 2010Assignee: Plastic Tubing Industries, Inc.Inventors: Michael D. Maroschak, Douglas G. Everson, Marc H. Maroschak, Scott M. Thomson

Patent number: 7638445Abstract: This invention generally relates to the production of a composite yarn or non-woven strand wherein a core of super absorbent fibers or polymers (SAP's) having a swell factor of approximately 25% and greater are encapsulated by a nonwoven membrane of defined porosity. The membrane is then sealed in a fashion to generally deter or prevent the SAP material from migrating out of the core as water is freely absorbed and desorbed from the composite yarn structure. The strands of yarns or strips of non-woven material are subsequently constructed into an open or unorientated fabric formation. When used as a subterranean fabric, structure or material, the resultant fabric structure retains moisture while permitting normal root growth and allowing excess water to pass through and beneath the fabric while facilitating movement of water from lower levels to the surface.Type: GrantFiled: April 11, 2007Date of Patent: December 29, 2009Inventor: Gilbert Patrick

Patent number: 7632408Abstract: A passive drain field assembly reduces nitrogen in wastewater by facilitating nitrification and denitrification. A first chamber receives effluent into a multi-pipe bundle. An air vent is provided that extends from the atmosphere into the first chamber. A second chamber receives effluent from the first chamber, and contains a medium, beneath which is positioned a drainage pipe for releasing treated effluent into the soil therebeneath. A berm creates a retention area in the second chamber that is lined with a water-impermeable liner. In use, ammonia present in the effluent is converted to nitrate in the presence of the oxygen admitted by the air vent in the first chamber. The liquid retained upstream of the berm and above the liner undergoes anaerobic reactions. The remaining liquid proceeds to a place in the second chamber from which the drainage pipe can be entered, from which the treated wastewater can enter the soil.Type: GrantFiled: June 27, 2008Date of Patent: December 15, 2009Assignee: Plastic Tubing Industries, Inc.Inventor: Douglas G.

Patent number: 7628565Abstract: A drainage pipe to be inserted into the ground, presents a plurality of openings (5) for the passage of water, wherein each of the openings is closed by a cap (9) containing one or more holes (11) filled with water-soluble material (13), adapted to prevent the passage of debris during drilling, which the material dissolves in contact with the water in the soil. In particular, the caps have a hollow body (9) with a plurality of holes (11) in the wall for the passage of water, which the body and holes are filled with water-soluble material (13). Moreover, the caps present an undercut (12) on the end wall of the cavity, to prevent the exit of the water-soluble material (13) which fills the hollow body (9).Type: GrantFiled: October 2, 2007Date of Patent: December 8, 2009Inventor: Cesare Melegari

Publication number: 20090297271Abstract: A perforated pipe network beneath a playing surface. A blower connected to the pipe network drawing an air flow through the pipe network to create a vacuum. A drain pipe connecting to the pipe network. An air/water separator connected upstream of the blower for separating water from the air flow prior to entering the blower and channeling the water into the drain pipe for discharge. A flow control unit having a unit inlet connected to the drain pipe downstream of the air/water separator and a unit outlet discharging water to a drain outlet. The flow control unit blocking air flow through the unit inlet into the drain pipe when the blower is in the vacuum mode, and opening the unit inlet when a waterhead buildup at the unit inlet exceeds the vacuum level established by the blower to discharge water through the drain outlet.Type: ApplicationFiled: February 21, 2006Publication date: December 3, 2009Inventors: George T. Hummert, Fredrick O. Hartenstein

Publication number: 20090290937Abstract: Synthetic rocks are used as a substitute for natural gravel to fill in a water drainage trench. The synthetic rocks may be used around perforated drain tiles in a basement water drainage system, or they may be used without such tile. The synthetic rocks may be of a size and shape that mimics the natural rock they replace, but they are preferably significantly lighter in weight. The synthetic rocks may alternatively be tubular or cubic shaped, for example, and may include one or more lumens or other passageways to facilitate the flow of water through and/or around the rocks. The synthetic rocks may be provided in mesh bags to facilitate placement in a water drainage trench.Type: ApplicationFiled: June 2, 2009Publication date: November 26, 2009Inventor: Scott Nordhoff
