Abstract
Description

- 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.
- 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 or receptacle that is connected to the underground conduit network by a vertical pipe or riser.
- 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. Therefore, the catch basins or receptacles may require housing extensions of various dimensions to connect to the conduit 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.
- Accordingly, it would be advantageous to provide a catch basin assembly that can be used with typical buried pipe drainage system, wherein the catch basin assembly has an improved ability to keep particulate debris out of the underground conduits, and wherein the catch basin assembly easily adapts to varying depths of the underground conduits. Moreover, it would be advantageous to make such an assembly with components that are nestable or stackable for ease of storage and transport.
- Broadly, the present invention is a catch basin assembly for a drainage system having a buried drainage conduit, the catch basin assembly comprising a housing having an open top and an outlet at the bottom adapted for connection to the buried drainage conduit; and a debris trap removably mounted in housing, wherein the debris trap retains particulate matter entering the housing with water flowing into the top of the housing, while allowing water from which the debris has been removed to flow through to the outlet. More specifically, in a preferred embodiment, the debris trap comprises a bowl for retaining the debris; a retention rim or lip that surrounds the top of the bowl, and that engages an internal shoulder within the housing; and a circumferential array of apertures below the rim, whereby, when the level of water in the bowl reaches the array of apertures, the water flows out of the bowl and through to the outlet. When the bowl of the debris trap is filled with debris (or at predetermined time intervals), the debris trap is simply removed and replaced with a clean unit. A preferred embodiment of the invention also includes a cover with a grate section removably installed in the top of the housing.
- 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.
- 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.

FIG. 1 is a perspective view, partially in section, of a catch basin assembly, in accordance with a preferred embodiment of the present invention, as connected to a buried drainage conduit by a riser; -
FIG. 2 is a perspective view of the removable debris trap used in the catch basin assembly ofFIG. 1 ; -
FIG. 3 is a bottom perspective view, partially in section, of the catch basin assembly ofFIG. 1 ; -
FIG. 4 is an axial cross-sectional view of the catch basin assembly ofFIG. 1 ; -
FIG. 5 is an axial cross-sectional view of a plurality of catch basin housings, of the type used in the catch basin assembly ofFIG. 1 , wherein the housings are stacked in a nested stack; and -
FIG. 6 is an axial cross-sectional view of a plurality of debris traps, of the type used in the catch basin assembly ofFIG. 1 , wherein the debris traps are stacked in a nested stack. - Turning first to
FIGS. 1 through 4 , acatch basin assembly 10, in accordance with a preferred embodiment of the present invention, is shown connected to a pair ofconduits riser 14 and an inverted “T” fitting 16. Theconduits riser 14 by the “T” fitting 16 by any conventional means well-known in the art. For example, theupstream conduit 12 a is inserted into one horizontal leg of the “T” fitting 16, thedownstream conduit 12 b is inserted into the other horizontal leg of the “T” fitting, and theriser 14 is inserted into the upright (vertical) leg of the “T” fitting. Theconduits 12 a, 12 and theriser 14 may be secured to the “T” fitting 16 by any suitable means. For example, if these components are made of PVC tubing, they may be secured by any suitable adhesive. - The catch basin assembly itself comprises a receptacle or
housing 18, adebris trap 20, anoutlet portion 22, and agrated cover 24. Thehousing 18 may be of any suitable shape that can be configured to be stacked in a nesting relationship (as will be described below). In the exemplary embodiment shown, thehousing 18 is in the form of a pair of inverted, truncated, right frusticones conjoined end-end-to-end (i.e., axially). Thus, thehousing 18 has a circular cross section and an outside diameter that decreases in the axially downward direction so that thehousing 18 tapers radially inward from top to bottom. The quality of nestability can be obtained with a housing having a rectangular (particularly, a square) cross section, wherein the perimeter decreases from the top of the housing to its bottom to provide the inward taper. Other housing configurations may also be suitable for this purpose. - The
outlet portion 22 is formed integrally with, and extends downwardly from, the bottom of thehousing 18. Theoutlet portion 22 is tubular, and it has a bifurcated wall that defines an annular slot 26 (seeFIGS. 3 and 4 ) that is dimensioned to receive the upper end of theriser 14 for connecting thehousing 18 to theriser 14 in a fluidly-coupled relationship, as shown inFIG. 1 . - The upper end of the
housing 18 defines a large inlet opening in which thecover 24 is advantageously installed. Thecover 24 typically includes anapertured grate 28, a firstannular lip 30 surrounding thegrate 28, and atubular portion 32 depending downward from thegrate 28. The diameter of thelip 30 is approximately equal to the diameter of the open upper end of thehousing 18, so that thelip 30 seats on the open upper end of thehousing 18, as shown inFIGS. 1, 3 , and 4. Thetubular portion 32 fits inside the top of thehousing 18 with a friction fit, and is unsecured, so that it is removable. In the exemplary embodiment shown, thecover 24 is substantially circular in cross section to conform to the circular cross section of thehousing 18. If the housing were to be square, for example, the cover would likewise be square. - As mentioned above, in the exemplary embodiment shown, the
housing 18 is formed of two axially-conjoined, inverted, truncated right frusticones. In this configuration, the exterior of thehousing 18 includes a radially inward-directedannular step 34 around its perimeter, approximately at its mid-section. Theannular step 34 corresponds to anannular shoulder 36 around the interior wall of thehousing 18. Theshoulder 36 supports thedebris trap 20, as explained below. - The
debris trap 20, as best shown inFIG. 2 , comprises a bowl orpan 38 having an exterior surface that tapers radially inward in the axially downward direction. Integral with the top of thebowl 38 is an annular flow-throughsection 40 defining a circumferential array ofapertures 42 separated byribs 44. The flow-throughsection 40 is topped by a secondannular lip 46, the diameter of which is approximately equal to the diameter of theannular shoulder 36 in thehousing 18, so that when thedebris trap 20 is installed in thehousing 18, the secondannular lip 46 seats on theshoulder 36. Thus, when thecover 24 is removed, thedebris trap 20 can be removably installed in thehousing 18, and then removed when full of debris, or whenever it is desirable to do so. - Referring again to
FIG. 1 , with thecatch basin assembly 10 connected to theconduits riser 14, water entershousing 18 through thegrate 28 in thecover 24. Thegrate 28 blocks the entry of larger objects. The water then flows down into thebowl 38 of thedebris trap 20, which captures and retains smaller debris particles, such as sand and silt, which settle out into thebowl 38. When the water in thedebris trap 20 reaches the level of the flow-throughsection 40, it flows out of theapertures 42 down into the bottom portion of thehousing 18 and through theoutlet portion 22 into theriser 14, and then into “T” fitting 16, from which it enters the buriedconduits 12 a and/or 12 b. Whenever it is desired to remove thedebris trap 20, thecover 24 is removed, and thetrap 20 is lifted out. Thetrap 20 can then be emptied of debris and replaced, or anew trap 20 can be installed. -
FIG. 5 shows how the external configuration of the housing, as described above, allows a plurality ofhousings 18 to be stacked in a nesting relationship to save space during storage and transit. Likewise,FIG. 6 illustrates a plurality of debris traps 20 stacked in a nesting relationship, as allowed by the external configuration described above. - While a preferred embodiment of the invention has been described above and is illustrated in the accompanying drawings, it will be appreciated that this embodiment is exemplary only. Thus, a number of variations and modifications may suggest themselves to those skilled in the pertinent arts. For example, the housing and the debris trap may be any convenient shape other than circular in cross section, and the debris trap may be removably retained or held in the housing by any suitable mechanism. Moreover, the
debris trap 20 described and shown in the accompanying drawings is merely one example of various functionally equivalent debris trapping means that would suggest themselves to those skilled in the pertinent arts. These and other modifications and variations are considered to be within the spirit and scope of the invention, as defined by the claims that follow.
