  • 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.

  • Patent number: 7364384
    Abstract: A thermoplastic chamber for leaching wastewater or other use, which is designed so that when jointed to a like chamber the horizontal plane angle between the chambers can be adjusted, has one or more stops which can be selectively used to prevent rotation, for instance, to make the joined-together chambers lie along a straight line. Preferably, the stop is integral part of the chamber base flange; and it hinges and bends upwardly when moved to its working position, so the stop engages and limits movement of the end of the mating chamber.

  • Patent number: 7351006
    Abstract: Arch shape cross-section leaching and stormwater chambers are connected together so that swiveled angling is obtained at the joint. Angling is accomplished by means of an integral or detachable dome end comprising a conical section. A like chamber with an ordinary end mates by overlapping the dome. Or a like chamber may have an opposing and overlapping end, which also comprises a dome. A coupling for connecting two ordinary end chambers is comprised of two spaced apart conical domes spaced apart by a connector. The connector between the domes is optionally straight or angled. The couplings enable chambers to be connected at diverse angles to each other, as well as to be connected parallel with offset, i.e., with zigzag path.

  • Patent number: 7351005
    Abstract: A leaching device having slots to frictionally engage soil to permit the introduction of water through the slots and into the soil while prohibiting the excessive passage of soil particles through the slots. A method of introducing water into soil by passing water through slots that frictionally engage soil to permit water to pass through the slots and which prohibits the excessive passing of soil particles through the slots.

  • Patent number: 7311467
    Abstract: A leaching chamber, particularly a chamber which lacks ribs and is therefore flexible along its length, has a length in the range 4 to 5 ft, a length to width aspect ratio of between 1.2 and 1.6 and a weight of less than 3 pounds per foot, preferably about 12 pounds for a 4 ft chamber. Since the chamber length is less and the mass is more favorably concentrated, handling of chambers, and installing chambers in trenches is improved. The ability of a string of interconnected chambers to curve is increased.

  • Patent number: 7300226
    Abstract: An assembly for receiving and diffusing stormwater in underground installations includes a horizontally elongated plastic chamber having an arched cross-sectional shape with an upwardly directed apex having an inlet portal. A sediment-accumulating compartment is positioned below the chamber in vertical alignment with the portal. A rigid riser pipe of circular cylindrical configuration penetrates the portal and extends vertically between a bottom extremity located within the chamber and a top extremity positioned substantially at ground level in association with a grated street-level stormwater receiving structure.

  • Publication number: 20070264082
    Abstract: A splash plate for use with an end cap or end portion of a chamber is provided, wherein the end cap or end portion defines an end cavity having an open end cavity bottom and includes an opening for containing a waste water pipe that introduces waste water into the end cavity. The splash plate includes a base panel for covering the end cavity bottom such that waste water introduced into the end cavity contacts at least a portion of said base panel and a means for positionably securing the splash plate relative to the end cap or end portion.

  • 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.
