Abstract: A drainage system includes a storm water chamber and riser assembly for gathering and dispensing liquids. The storm water chamber comprises a generally elongated arch shape with an arch top and bottom side walls, thereby defining an enclosure. The riser assembly has two generally parallel base assemblies, which each have an outer wall and an inner wall and a top wall connecting the outer wall and the inner wall. The top wall has a chamber seating area for receiving the base area of the chamber and a retaining element for retaining the base area of a chamber in position in the chamber seating area.

Abstract: A drainage system includes a storm water chamber and floor liner assembly for storing and conveying liquids. The storm water chamber comprises a generally elongated arch shape with an arch top and bottom side walls, thereby defining an enclosure, the enclosure having a plurality of liquid intake openings. The floor liner comprises two generally parallel sides each having a plurality of retaining members for connecting the storm water chamber. When the storm water chamber and floor liner are connected with each other, the system provides a substantially enclosed assembly for conveying liquids.

Abstract: A connection chamber for waste water and storm water collection, the connection chamber including an arch-shaped cut out in a side thereof, the arch-shaped cut out sized to receive an arch-shaped row connector, which is provided to couple rows of chambers to each other. The coupling of various rows of chambers to each other facilitates to relatively even flow of fluid throughout the field of chambers.

Abstract: A storm water and septic system using plastic galleries that have multiple layers provided having differing hardness characteristics, the exterior layer having a lower hardness rating than an inner layer; and a multi-layer gallery where the inner layer is treated to be resistance to degradation to a selected chemical that would otherwise degrade polyethylene. The gallery may further be provided with an interior layer having defined dielectric properties such that a fluid level measurement can be made of fluid in the galleries.

Abstract: A gallery for guiding liquid through a leaching or drain field and allowing liquid to seep into adjacent ground is provided. The gallery includes an elongated main body portion having an undulating wall defined by a plurality of laterally spaced apart ribs, the undulating wall defining an outer surface and an interior space for liquid and particles to flow therethrough. A plurality of area enhancing elements are formed on the outer surface of the undulating wall for increasing a surface area of the outer surface to promote the growth and flourishing of the bacteria and other microorganisms on the outer surface.

Abstract: A chamber is provided that is flexible and able to be contoured along the entire length of the chamber when deployed on rock and earth formations with variable gradings. The chamber has a multiplicity of stress relief notches (also known as flex ports) formed on both sides at the base of the chamber Substantially along the entire length of the chamber. Each stress relief notch is formed between a respective pair of protruding ribs along substantially the entire length of the chamber so the chamber can flex in an accordion-like or caterpillar-like manner. The chamber may be molded to include the strain relief notches.

Abstract: A first molded polymer field drain panel is made from a moldable polymer sheet material and has an elongated chamber with an arched-shape, a first end, a second end and transverse strengthening ribs protruding outwardly therebetween. The elongated chamber has a smaller transverse strengthening end rib, a transverse strengthening end rib and a smaller transverse strengthening intermediate rib. The smaller transverse strengthening end rib is molded at the first end shaped for being embracingly overlapped by a corresponding transverse strengthening end rib of a corresponding elongated chamber of a second molded polymer field drain panel. The transverse strengthening end rib is molded at the second end for overlapping a corresponding smaller transverse strengthening end rib of the corresponding elongated chamber of the second molded polymer field drain panel.

Abstract: A lightweight and durable utility pull box for storing splices and junctions of underground coaxial cables, electrical wires, and optical fibers, having an elongated main body portion and end walls. The elongated main body portion is made of durable and lightweight plastic material for providing chemical resistance and structural integrity, has sidewalls with an arch-shaped configuration defining an enlarged inner enclosure for storing splices or junctions for electrical, telephone, coaxial cable or optical fiber cable, and has side walls with outer laterally extending strengthening ribs. The end walls cover the ends of the inner enclosure defined by the elongated main body portion. The elongated main body portion has at least one inlet opening for receiving the electrical, telephone, coaxial cable or optical fiber cable for splicing or joining together and storing inside the enlarged inner enclosure.

Abstract: A system for filtering, storing, and distributing groundwater, which includes a gallery having an elongated main body portion with an arch-shaped configuration with an enlarged inner chamber, having end walls covering each end thereof with an inlet opening for receiving the liquid to the enlarged inner enclosure, having side walls with laterally extending outer ribs and inner corrugations within the elongated body portion. The system also includes a collapsible filter having a hinged frame with a filtering material and a side portion for sliding into the inner corrugations of the gallery.

Abstract: In septic systems for handling household waste water or in clear water drainage applications, lightweight molded polyethylene galleries are used to form the drain field. The galleries can be axially aligned in end-to-end relationship with each gallery defining an interior hollow chamber. A unique latching system is used to attach adjoining galleries to one another. A perforated delivery conduit extends through and introduces effluent into the hollow chambers of the galleries where it is allowed to seep therefrom into the surrounding earth through the open bottoms of the galleries or through infiltration apertures in the walls of the galleries.
