Publication number: 20080193217Abstract: A frame for retaining a grate over a trench for directing storm water to subterranean basins includes a frame that is embedded in the concrete surrounding the trench. The frame includes a vertical support that is sized and dimensioned to abut the pavement wall of the trench, and a horizontal flange extending from the vertical support to support a grate. The horizontal flange and grate each include a plurality of apertures that are configured to be aligned to receive coupling devices for securing the grate to the frame. A chute is positioned beneath each aperture in the frame to direct debris from the aperture to the trench.Type: ApplicationFiled: February 13, 2008Publication date: August 14, 2008Inventor: Steven M.

Publication number: 20080181725Abstract: A water collection and storage assembly for dispersion of water comprises a half pipe assembly comprising at least one half pipe having an inlet, an outlet, a top, a bottom, a corrugated exterior comprising alternating ribs and valleys, and at least one side port positioned above the bottom of the half pipe, and a sleeve positioned in an installed position within the half pipe and defining a smooth interior, wherein the sleeve extends from the bottom of the half pipe to a height less than the at least one side port. The half pipe assembly can define a chamber and the sleeve has a dimple which extends into the chamber. The sleeve can have an opening which allows projections of the port hole to extend through the opening and into the chamber.Type: ApplicationFiled: January 23, 2008Publication date: July 31, 2008Inventor: Joseph S.

Patent number: 7396188Abstract: A continuous curve arch shape cross section leaching chamber made of molded thermoplastic has closely spaced corrugations and sidewalls, portions of which are perforated with horizontal slots. Either or both of the slot height and the local wall thickness which defines the slots may vary with slot elevation from the base, so that a perforated sidewall configuration is achieved which resists entry of surrounding soil. In one embodiment, the slotted sidewall has slots with all the same slot openings and the wall thickness decreases with elevation.Type: GrantFiled: March 12, 2007Date of Patent: July 8, 2008Assignee: Infiltrator Systems, Inc.Inventors: Ronald P. Brochu, James J. Burnes, John R. Battye, Roy E. Moore, Jr., Bryan A. Coppes

Patent number: 7384212Abstract: A modular appendage for a septic gallery has a first modular section for connection to a lateral side of the gallery with the first modular section having a number of apertures thereon. The first modular section has a first area. The lateral side of the septic gallery has a second area. The first area is greater than the second area for increased drainage and thus adds capacity to the gallery.Type: GrantFiled: September 26, 2005Date of Patent: June 10, 2008Inventor: Frank Currivan

Publication number: 20080131206Abstract: A fluid injection and removal system to inject or remove fluids from a landfill or contaminated area. The system allows for treatment of waste in the landfill or the contaminated area. The fluid injection and removal system includes a permeable layer and at least one perforated pipe. The permeable layer enables essentially uniform distribution of the fluid into the underlying waste or contaminated area. The fluid injection and removal system can be combined with a leachate collection system to create a leachate recirculation system for use in a landfill. The leachate collection system includes at least one perforated collection pipe embedded in a drainage layer. Sensors can be provided in the permeable layer to enable the change in the physical characteristics of the waste adjacent the permeable layer to be monitored.Type: ApplicationFiled: October 29, 2007Publication date: June 5, 2008Applicant: Board of Trustees of Michigan State UniversityInventor: Milind V.
