Abstract
A stormwater system for capturing and retaining trash and debris entrained in the stormwater. The stormwater system includes an outlet pipe disposed adjacent a stormwater pond. A bag-type filter is secured to the outer end portion of the outlet pipe for catching and retaining trash and debris and preventing the trash and debris from being discharged into the stormwater pond.
Description
- The present invention relates to a stormwater system that includes a stormwater pond, an outlet pipe for directing runoff into the stormwater pond and means to capture debris and trash entrained in the runoff prior to the runoff being discharged into the stormwater pond.
- Stormwater ponds are employed in commercial and residual areas to collect—from roads, parking lots, roofs, etc. The stormwater is typically channeled through various feeder pipes to an outlet pipe disposed in close proximity to a stormwater pond. Stormwater is discharged from the outlet pipe into the stormwater pond. The stormwater pond is typically designed to discharge the stormwater therefrom at a controlled rate over time which avoids flooding and erosion.
- There is one major problem with stormwater ponds. They must be periodically inspected, cleaned and maintained. Invariably, trash and debris of various types become entrained in the stormwater, flow with the stormwater into inlets, through feeder pipes and through the outlet pipe into the stormwater pond. Removing this trash and debris from the stormwater pond is time consuming, labor intensive, and in the end, extremely expensive. And, too, the cleaning requirement is never ending. It must be periodically done for the life of the stormwater pond.
- There has been and continues to be a need for a stormwater system that facilitates a more efficient way of dealing with trash and debris entrained in stormwater.
- The present invention addresses this problem. In one exemplary system, a trash and debris retainer in the form of a porous bag or netting, for example, is secured about the outlet end portion of the outlet pipe. Trash and debris entrained in the stormwater is captured in the retainer. Periodically or from time-to-time, the captured trash and debris are emptied from the retainer.
- In one exemplary design, the trash and debris retainer when secured about the outlet end portion of the outlet pipes includes an inlet or first opening that extends around the outlet pipe and a second closeable access opening. Trash and debris can be removed from the retainer by opening the second opening and gaining access to the interior of the retainer. Now captured trash and debris in the retainer can be manually removed through the second opening without removing the retainer from the outlet pipe.
- The present invention also comprises a method for treating stormwater. In one embodiment, the method includes capturing the stormwater in one or more inlets of a stormwater system. After catching the stormwater, the stormwater is directed, along with the trash and debris therein, to an outlet pipe disposed adjacent a stormwater pond. The stormwater is directed from the outlet pipe into the stormwater pond. Further, the method includes attaching a permeable bag-type filter to the outlet end portion of the outlet pipe. The method thus includes directing the stormwater from the outlet pipe through the bag filter and into the stormwater pond. As the stormwater flows through the bag filter, the method entails catching the trash and debris in the bag filter and preventing the trash and debris from being discharged into the stormwater pond. The method also includes retaining the trash and debris in the bag filter while stormwater flows through the bag filter. At selected times, the bag filter is opened and the accumulated trash and debris is removed therefrom.
- Other objects and advantages of the present invention will become apparent and obvious from a study of the following description and the accompanying drawings which are merely illustrative of such invention.

FIG. 6 is a fragmentary top plan view illustrating the retainer ofFIG. 5 . - With further reference to the drawings, the stormwater system of the present invention is shown therein and indicated generally by the
numeral 10. SeeFIG. 1 . Stormwatersystem 10 includes various stormwater inlets for receiving stormwater runoff from streets, parking lots, roofs, lawns, etc. In one example, the stormwater inlets may be catchbasins 12. These stormwater inlets are generally connected to one or more feeder pipes that collect the stormwater from the various stormwater inlets and direct the stormwater to an outlet pipe indicated generally by thenumeral 14.Outlet pipe 14 includes anoutlet end portion 14A. SeeFIG. 2 . In the example shown in the drawings, theoutlet end portion 14A is flared outwardly and a top portion of the flared end is removed. SeeFIGS. 2 and 4-6 . It is appreciated that the specific design of theoutlet pipe 14 can vary. The design shown in the drawings is simply one exemplary design of an outlet pipe. -
Outlet end portion 14A of theoutlet pipe 14 is disposed adjacent a stormwater pond indicated generally by thenumeral 16. Details of thestormwater pond 16 are not dealt with herein because stormwater ponds are well known. - As seen in the drawings, the
outlet end portion 14A of theoutlet pipe 14 is disposed in close proximity to thestormwater pond 16. That is, theoutlet pipe 14 is positioned with respect to thestormwater pond 16 such that the stormwater discharge from the outlet pipe is directed into the stormwater pond. The orientation of the outlet pipe with respect to thestormwater pond 16 can vary. The particular arrangement and relationship shown in the drawings is one example. - A trash and debris retainer, indicated generally by the
numeral 20, is associated with theoutlet pipe 14 for capturing trash, compost and debris, such as bottles, containers, toys, balls, etc., entrained in the stormwater passing through thesystem 10.Retainer 20 must be porous. That is, it must be sufficiently porous to allow water to freely flow through theretainer 20. But at the same time,retainer 20 is not so porous that targeted trash and debris pass through the retainer. There are a number of considerations when it comes to the placement of theretainer 20. First, the retainer must be upstream of thestormwater pond 16. The object of this invention is to prevent entrained trash and debris from entering thestormwater pond 16. A second requirement is that theretainer 20 must be positioned in place such that it is easily accessible by those charged with removing trash and debris from the retainer. Furthermore, it is advantageous if theretainer 20 is designed such that it can be opened and closed easily during the process of removing trash and debris therefrom. - The
retainer 20 can assume various designs and forms. In the case of the embodiment shown in the drawings, theretainer 20 assumes the form of a bag-type netting or mesh. As seen in the drawings, the retainer includes aninlet opening 20A that is sometimes referred to a first opening. As seen in the drawings, theinlet opening 20A is sized such that it can be extended over the outlet end portion of theoutlet pipe 14. SeeFIGS. 2 and 4-6 . In addition, theretainer 20 includes anaccess opening 20B. Theaccess opening 20B is normally closed so as to capture entrained trash and debris. When it comes time to remove the trash and debris from theretainer 20, theaccess opening 20B is easily opened and the trash and debris are removed therefrom.Access opening 20B can be designed in various ways. In this example, an end portion oppositeinlet 20A is provided with an opening. This opening, that is access opening 20B, can be gathered together and closed with a twist tie or other type of conventional closure devices in order to close the downstream end portion of theretainer 20 so that trash and debris cannot pass through the retainer. In addition, the access opening 20B may have associated therewith a drawstring. The drawstring is configured to close the access opening. In addition, the access opening can be pulled apart so as to form an open area that permits the retained or filtered trash and debris to be removed from theretainer 20. - There are various ways to secure the
retainer 20 in a proper position to capture trash and debris being discharged from theoutlet pipe 14. As shown in the drawings,retainer 20, when installed on theoutlet pipe 14, effectively forms a porous sock or bag with the access opening 20B disposed at the outlet end of the outlet pipe or downstream therefrom. In one embodiment, theretainer 20 assumes a porous bag-like structure. Indeed, the entire retainer can be elongated with theend openings - In one embodiment shown, the
retainer 20 is secured and held in place by twostakes 22. SeeFIGS. 1-4 .Stakes 22 can be constructed of metal, plastic, wood, etc. In one example, thestakes 22 are simply rebar. Note inFIGS. 2-4 that thestakes 22 are spaced just outwardly from the wall of theoutlet pipe 14 and driven into the underlying ground. Theinlet opening 20A of theretainer 20 is secured to thestakes 22 by any number of conventional fasteners, such as zip ties. Thus, the securement of theretainer 20 to thestakes 22 maintains the retainer about theoutlet end portion 14A of theoutlet pipe 14. Note that theretainer 20 extends completely around the outlet end portion of theoutlet pipe 14. Even though there may be a substantial flow of stormwater runoff passing through theoutlet pipe 14, this approach to securing theretainer 20 about theoutlet end portion 14A will maintain the retainer in place. Note that theretainer 20 does not have to extend around the largest diameter of theoutlet pipe 14. Note inFIGS. 3 and 4 that it is possible when there are heavy flow volumes for stormwater to pass over the top of theretainer 20. This is not concerning because generally that water will not include trash and debris. Trash and debris will almost always be entrained in the bottom portion of the stream where theretainer 20 will capture and hold the trash and debris. - Therefore, in use, it is appreciated that the
retainer 20 is placed and secured on the outlet end portion of theoutlet pipe 14 as discussed above. Over a period of time, trash and debris entrained in the stormwater will be captured in the downstream end of theretainer 20. From time-to-time, it will be necessary to remove the trash and debris from theretainer 20. Because of the design of theretainer 20 and how it is positioned on the end of the outlet pipe, accessing the retainer and removing trash and debris therefrom is a relatively easy task. To do so simply involves opening the access opening 20B and collecting the trash and debris and thereafter closing the access opening. - Various means and approaches can be employed to secure the
retainer 20 about theoutlet end portion 14A of theoutlet pipe 14. Another example of how this can be achieved is shown inFIGS. 5 and 6 . One will note that thestakes 22, shown inFIGS. 1-4 , have been eliminated. In order to secure theretainer 20 to theoutlet end portion 14A, there is provided a series of studs or screws that are secured in theoutlet end portion 14A. As shown inFIGS. 5 and 6 , the studs or screws 50 project out from theoutlet end portion 14A. As an alternative, the studs or screws 50 can be secured to an inside area of the outlet pipe. In addition, there is another stud or screw 52 secured to the top of theoutlet pipe 14. In this embodiment, the retainer is secured to thescrews 50. In one embodiment, zip ties are utilized to connect the mesh construction of theretainer 20 to the respective studs or screws 50. Note that the bottom portion of the inlet opening 28 is stretched or disposed along the underside of theoutlet end portion 14A of the outlet pipe. To finally secure theretainer 20 in place, theinlet opening 20A is provided with a drawstring. The drawstring is pulled to an appropriate tension such that theinlet opening 20A extends across theouter end portion 14A of theoutlet pipe 14. Once the retainer assumes a configuration similar to that shown inFIGS. 5 and 6 , the drawstring is extended upwardly and generally rearwardly to where the drawstring is attached to the stud orscrew 52. This securely connects or fastens theretainer 20 to theoutlet end portion 14A of theoutlet pipe 14. - The present invention may, of course, be carried out in other specific ways than those herein set forth without departing from the scope and the essential characteristics of the invention. The present embodiments are therefore to be construed in all aspects as illustrative and not restrictive and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
