Street Or Curb Inlet For Surface Drainage Patents (Class 404/4)
  • Patent number: 6972088
    Abstract: A pivotal gate system to be installed across the drain opening to a catch basin of a storm drain system and having a catch basin blocking gate that is adapted to rotate from a closed position extending completely across the drain opening at which to trap and prevent leaves, litter and other debris from entering the catch basin during dry periods and light rainfall to an open position removed from the drain opening at which to permit rainwater to enter the catch basin during periods of heavy rainfall. A water wheel is mounted for rotation within the catch basin. The water wheel is coupled to the catch basin blocking gate by way of a pulling cable. The water wheel rotates in response to impact forces caused by rainwater dropping downwardly on a plurality of scoops extending around the water wheel. A rotation of the water wheel generates a pulling force in the pulling cable to be applied to the catch basin blocking gate whereby to cause the blocking gate to move from the closed position to the open position.

    Abstract: A novel filtration media employing polymeric absorbents comprising a material selected from the group consisting of styrene, pentadiene, cyclopentadiene, butylene, ethylene, isoprene, butadiene, propylene and mixtures thereof; and a filtration enabler intimately mixed with the polymeric absorbent. Upon contact with a hydrocarbon containing liquid, the liquid partially dissolves the polymeric absorbent forming a partial filtration barrier prior to the filtration media substantially absorbing the hydrocarbons, and allowing hydrocarbon-free liquid to flow through the filtration media. In situations of a leak or spill wherein an excess of hydrocarbons are present, the filtration media forms a plug to seal and prevent further discharge of the hydrocarbons. The filtration media may be placed inside a portable container for insertion into an existing drain such that hydrocarbon containing liquid is filtered through the device allowing hydrocarbon-free liquid to flow from the device.

The surface water enters an inlet chamber which is separated from a settling chamber by a divider wall that has a lower opening between the chambers and a higher overflow. The inlet chamber traps floating contaminates and those that are heavier than the water. The opening between the chambers permits the surface water to flow into and through the lamella separator. The catch basin exit is from the settling chamber, but the water can reach the exit only through the lamella separator that separates out the fine sediment in the water. All of the accumulated contaminates can be removed through access holes in the top of the catch basin.

The locking device (34) includes a penetration (46) where a bolt (36) is inserted through the hole (60). As the bolt (36) is turned, the locking device (34) is raised until it contacts the frame (14), thereby securing the grate (12) within the frame (14).

    Abstract: A baffle insert for conversion of conventional gravity drains into siphonic drains. The baffle insert is placed into a sump bowl of a gravity drain and by nature of its design changes hydraulic condition in the drain to a siphonic condition. The baffle insert is composed of a baffle plate and a plurality of fin extensions coupled to a bottom surface of the baffle plate. In a preferred embodiment, the number of fin extensions is 12, and the bottom surface of the baffle plate has a concave shape.

  • Publication number: 20030132150
    Abstract: The present invention is a filter system for a curb inlet catch basin which catch basin includes a ramp in the curb front which feeds into a catch basin to allow storm water to run directly along the curb and down the ramp and which also has a grated cover so the water can enter directly through the grate. The water collecting trough is mounted inside the curb inlet catch basin at the bottom of the entrance ramp and has raised walls for collecting runoff water. A weir is formed into one of the raised walls allowing the water to run out of the trough. An elongated hydrocarbon collecting boom is removably attached adjacent the weir and positioned for the drain water passing through the weir to pass thereover. The catch basin is removably mounted to the trough adjacent the weir and positioned to receive water runoff from the trough through the weir and over the hydrocarbon collecting boom.

  • Patent number: 6562233
    Abstract: A drain filtering system is disclosed, having a filter placed within a basket which is suspended from frame positioned underneath a drain grate atop the inlet to a storm drain. The filter is constructed from materials that filter out heavy metals, sediments, debris and hydrocarbons from the water passing through. The system includes a riser tube having an inlet and an outlet, where the inlet is positioned inside the filer, and the outlet is positioned external to the filter. The inlet is placed close to the top of the filter to allow a bypass fluid path for periods of high flow.

  • Patent number: 6551023
    Abstract: A catch basin filtration system, comprising a filter body, dimensioned 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 the 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.

  • Patent number: 6551505
    Abstract: A filter for removing particulate matter from water flowing into an inlet, such as a catch basin is disclosed. The filter may comprise an envelope of filter material adapted to receive an inlet cover device, such as a catch basin grate. The inlet device may be inserted within the envelope and placed in an opening of the inlet. Water, for example, may then be double filtered before entering the inlet. A roll filter comprising porous material is also disclosed that may be used in combination or alone when filtering runoff entering a curb drain or other inlet.

  • Patent number: 6547962
    Abstract: An apparatus for separating floating and non-floating particulates from drain water wherein said apparatus includes a first chamber for collecting non-floating particulates, a second chamber for collecting floating particulates, and a third chamber through which treated drain water can be discharged from the apparatus. An inlet pipe for introducing drain water into the first chamber is provided tangential to the first chamber to provide a vortex flow of drain water into said first chamber. An outlet pipe providing flow of drain water from the first chamber to the second chamber has an inlet at the vortex of drain water flow in the first chamber and an outlet that is spaced a predetermined distance from the floor of the chamber.

  • Patent number: 6537446
    Abstract: An apparatus and system for removing debris and contaminants from water passing through a storm drain generally includes a debris trap adapted to fit within a storm drain a porous, filtering element adapted to separate debris from a water flow passing through the storm drain and a frame for directing the water flow into the porous element. The debris trap includes a frame element adapted to substantially prevent bypass of the debris trap, especially during low water flow conditions. The system may further include a debris block adapted to prevent debris from entering a back curb inlet opening of the storm drain. The debris block includes foam end members for adjustably securing and/or sealing the debris block to edges of the drain inlet.

  • Patent number: 6537447
    Abstract: A sewer basket and its support are to be positioned at any selected level within a vertical sewer pipe having an interior surface and an opening, of reduced size or not, at street level. The basket support is secured to the interior surface of the sewer pipe to receive the basket that includes a plurality of filter units adjacently and releasably resting on the basket support. Each filter unit is so sized as to get through the sewer opening while being in a substantially horizontal orientation. Each filter unit includes a frame, a filter screen secured to and extending across the frame, and a handle device accessible from the pipe opening to properly position, place and retrieve the unit on and from the basket support respectively. The basket support includes an intermediate support having a generally flat lattice shape that abuttingly rests thereon and that abuttingly supports the filter units.
