  • Patent number: 7481921
    Abstract: Embodiments of a filtration device, kit and method related to filtration in storm water systems are disclosed. A filtering device generally includes a mat adapted to filter water flowing through an inlet. The mat may have a top with a mesh cover, a main filtering portion and a bottom. The main filtering portion is formed of randomly-aligned fibers and a binding agent which impart a porosity that allows water to flow through generally unimpeded while sediment is filtered by the mat. A filtration kit is provided which could include the mat or other filtering device, a plurality of attachment members and a plurality of disks which allow for securing of the attachment members. Filtration device and kit are generally easy to install and clean, durable, less expensive than competing systems, and reusable.

  • Patent number: 7040838
    Abstract: A catch basin filtration system having a filter body dimension to fit within a drain inlet forming a trough or reservoir obstructing at least a portion of the inlet. The filter body is supported by a filter body support dimensioned to cooperatively engage with the interior walls of the inlet and with the filter body to substantially maintain said filter body in a pre-selected shape and position within the inlet. One or more connectors removably connect the filter body to the filter body support. One or more adjustable high fluid flow bypasses prevent the system from backing up and flooding surrounding areas during periods of high fluid flow.

  • Patent number: 7033489
    Abstract: A drainage assembly (10) comprises a frame (11) for defining at least part of the surface boundary of a surface drainage aperture; and a grating (14) having formed therein a plurality of apertures. The grating (14) is hingedly secured to the frame (11) and is moveable, when so secured, between an operative position in which the grating (14) is contiguous with the frame (11); and an open position in which the grating (14) lies hinged away from the frame (11). The grating (14) includes protruding therefrom a pair of forks (34, 36). The frame (11) includes a pair of journal bearings (37, 38). The forks each have protruding therefrom a respective protuberance (39) that is receivable in a respective journal recess (42) formed in the journal bearings.

  • Patent number: 7008137
    Abstract: The invention relates to a cover (1) for a drainage channel (2) to be installed in the ground to drain the surface of an area. The cover (1) comprises a substantially planar portion (3) which is constructed so as to cover an opening at the top of the drainage channel (2) and which comprises a projection (5) that extends upward from the planar portion (3). The projection (5) defines an inlet (7) through which the water that runs off from the surface to be drained can enter the drainage channel. In addition, the planar portion (3) defines comprises supplementary apertures (9) to receive water that has percolated down to its lower level.

  • Patent number: 7005060
    Abstract: A surface water runoff filtration device comprises an intake which is adapted to receive storm water and other surface water runoff. The surface water runoff flows from the surface through the intake to a point below the filter media, and then up toward the surface through the filter media. This device may be used in both catch basin storm drains and inline drains.

  • Patent number: 7005061
    Abstract: A drain filter device includes a body formed from wire mesh having a plurality of side edge portions integral with each other and forming a substantially square shape. The body further has substantially planar top and bottom surfaces and includes a plurality of elongated support rods having opposed end portions extending along the plurality of side edge portions respectively. The device further includes a top section having a substantially cylindrical shape and connected to the body. The top section is adaptable to be positioned substantially centrally about drain and for filtering out particulate materials suspended in water entering the drain. Advantageously, the top section traps and maintains particulate materials about a perimeter of a drain and not directly above same.

  • Patent number: 6997636
    Abstract: An apparatus for connection of a drain inlet to a vertical fixed runoff drainage pipe includes an intermediate adapter plate with a cylindrical shank that can be inserted in an impervious manner into a drainage tube at an adjustable relative height. The drain is slidably mounted such that it is guided bilaterally in translation over the plate. In this way, the drain can be disposed at a final determined position in relation to a curb before being sealed to the curb.

  • Patent number: 6974540
    Abstract: A street curb drain filter is comprised of U-shaped brackets for attaching to an inside wall of a street curb drain adjacent an inlet. A horizontal retaining bar is attached to the outer ends of the brackets. The lower edge of a horizontally elongated flexible net is attached to the retaining bar. The upper edge of the net is connected to the interior ceiling of the drain with eye bolts and S-hooks. A horizontally elongated debris basin is supported within the brackets. A filter media pack is positioned inside the basin adjacent a perforated outer wall of the basin. Water flowing from the street into the drain is directed through the filter. When runoff is relatively light, debris flowing into the drain is collected inside the basin. When runoff is relatively heavy or when the basin is clogged, debris bypassing the basin is filtered by the net.
