  • Patent number: 8562250
    Abstract: A method and pumping/drainage channel member for injecting surface water into the soil beneath a ground area includes drilling a series of holes and inserting an elongated pumping/drainage members into each hole extending downwardly into the soil. The pumping/drainage channel members comprise a cluster of integrally joined channel features each formed with a lengthwise extending slot opening. Surface water flows to the pumping/drainage member, enters the channels and drains down the pumping/drainage members to enhance water movement down into the soil to reduce runoff and help to recharge acquifers. Longer members may be installed between shorter members in a pattern to achieve more rapid injection of water deep into the subsoil.

  • Patent number: 8056629
    Abstract: A system is disclosed for supplying water to a desalination plant from a subsurface feedwater supply using one or more slant wells. A method is disclosed for constructing a slant well feedwater supply system for supplying water from a subsurface feedwater supply. A system of angled wells (slant wells) is constructed. The slant wells obtain a desalination feedwater supply from permeable aquifer systems near and/or beneath a saline water source (i.e., an ocean, sea, or salty inland lake). The slant wells induce recharge of the aquifer system through the floor of the ocean, sea, or inland lake due to the hydraulic head difference between the slant well pumping level and the level of the ocean, sea, or lake. As the supply source is relatively constant, the water supply to such a slant well system generally provides a long-term, sustainable water source for a desalination plant.

  • Patent number: 7993076
    Abstract: A system and method to remove surface water from a watershed atop a hill behind a bluff to an outfall point near a toe of the bluff, and a method to build the system. The system includes a catch basin structure and a catch basin drain pipe directionally bored from the catch basin structure to the outfall point. The location of the catch basin is determined based on a location of the outfall point and a desired slope of the catch basin drain pipe. The catch basin structure has a catch basin with an opening near its bottom, and a cover structure that provides a sculpted, rounded and smooth transition from the opening to a reducing pipe coupled with the catch basin drain pipe.

  • Patent number: 7993729
    Abstract: Disclosed is a substrate for artificial turf that includes a base pad with a channel that extends across an upper surface of the pad and a tube that lies within the channel. The base pad has a generally flat lower surface and a generally flat upper surface that is spaced apart and oppositely disposed from the lower surface. The channel has a sidewall and a bottom surface, the sidewall extending from the upper surface of the base pad to the bottom surface of the channel and the bottom surface being spaced apart from the lower surface of the base pad. The tube has a sidewall defining an inner diameter surface and an outer diameter surface, with at least one aperture through the sidewall adjoining the inner diameter surface and the outer diameter surface. The channel and the tube are operable for liquid to flow through. In some instances, a radiant heating wire can extend across the upper surface of the base pad.

  • Patent number: 7988851
    Abstract: A stormwater control system including conveyance, filtration and discharge systems. The conveyance system includes a set of conduits and connections providing a flow path through a compacted soil embankment from an upper inlet to a lower discharge area of an underlying soil infiltration zone. The control system has configurations for transferring stormwater from pervious and impervious surfaces to the soil infiltration zone. The control system optionally includes a media filter device that may be installed within the conveyance system to intercept sediment and other contaminants prior to discharge within the underlying soil infiltration zone.

  • Patent number: 7938597
    Abstract: A subsurface drainage assembly for directing fluid drainage from a surface is disclosed. The subsurface drainage assembly includes a plurality of drain structure panels linked together in a manner that permits movement of one drain structure panel relative to the adjacent drain structure panel. The drain structure panels have a laterally extensive backing grid and a plurality of spaced apart tubular support members projecting therefrom. The tubular support members are tapered so that the tubular support members are nestable with the tubular support members of an identical drain structure panel when the drain structure panels are stacked.

  • Patent number: 7918996
    Abstract: The invention is a particle and sediment filter for stormwater. A long permeable filter bag is laid out horizontally within an enclosure. The bag is formed of at least two layers of parallel tubes that give each layer the pleated look of a typical air mattress. Stormwater is collected from the filter bag by perforated pipes held within the creases between the tubes of the layers of the bag, with the pipes draining to the outside of the enclosure. The bag is also supported above the bottom of the enclosure by additional perforated pipes located within the creases between the tubes, thus allowing the filtered liquid to also drain off beneath the bag. The stormwater input is from a pipe that feeds a manifold formed in the bag and connected to each tube. The top of the enclosure is removable for replacing the filter. The filter bags are constructed of flexible material so that they are flat during initial transport and installation, but they expand as they are filled with liquid and solid material.
