Nestable catch basin assembly with removable debris trap

Abstract

A catch basin assembly for draining water into an underground drainage conduit through a riser includes a housing having an open top and a bottom including an outlet section configured for connection to the riser. A debris trap is removably installed in the housing so as to capture and retain particulate debris from water flowing into the housing through the top thereof, the debris trap having an apertured portion that allows water to flow from the debris trap to the outlet section. The housing has a tapered configuration, whereby two or more housings, with the debris traps removed therefrom, can be stacked in a nesting relationship.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] Not Applicable FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002] Not Applicable BACKGROUND OF THE INVENTION [0003] This invention relates to catch basins for drainage systems used, for example, to drain rainwater from a field. In particular, it relates to a catch basin assembly, including a basin portion and a removable debris trap, that is configured so that a plurality of the basin portions can be stacked or nested for space-efficient storage and transportation. [0004] Drainage systems are typically used to drain excess surface water (from rain or watering devices) from an area of land, such as an athletic field or a golf course, or from a landscaped or hardscaped area. Such systems typically include a network of underground conduits or pipes leading to a storm sewer, reservoir, receptacle, or pond (“buried pipe” systems). Surface water or run-off is collected in a plurality of drain assemblies, each of which comprises a catch basin ...

Benefits of technology

[0010] Also, in the preferred embodiment, the outlet is configured for attachment to the upper end (inlet end) of a vertical pipe or riser, the lower (outlet) end of which is fluidly coupled to the buried drainage conduit. Thus, a single housing size can be used throughout a drainage system, with risers of different length allowing the accommodation of different depths of the drainage conduit at different locations. Furthermore, in the preferred embodiment, the housing has a tapered shape, whereby a plurality of housings (with the grates and debris traps removed) can be nestably stacked for space-efficient storage and transport. Likewise, it is advantageous to configure the debris trap for nestable stacking.

[0011] As will be more fully appreciated from the detailed description set forth below, the present invention provides improved capture and retention of particulate debris as compared with prior art devices. Furthermore, the housings and (optionally) the debris traps can be nested for efficient storage and transportation. Finally, the housing can be connected to underground conduits of different depths merely be selecting risers of the appropriate length.

Problems solved by technology

In prior art drainage systems, a grate covering each catch basin or receptacle prevents some of the larger items of debris carried in the run-off or surface water from entering the drainage system, where such larger items of debris can cause clogs or stoppage.

Nevertheless, smaller debris particles, such as sand and silt, can still enter the system and block fluid flow to a degree sufficient to cause water to back up through the drain assemblies.

Another drawback to prior drainage systems is that, due to variations in the terrain, the depth of the drainage conduits below the surface may vary from place to place within the system.

Finally, in prior art drainage systems, the catch basins or receptacles are not nestable or stackable, thereby taking up much unnecessary space in storage and in transit.
