Water containment systems are designed to hold water and various pollutants, particles, and objects found in the water until such time as the water can be removed in such a manner that those pollutants, particles, and objects are left behind. In some cases, the water containment system is a basin or container. In other cases, the water containment system is a water reservoir to hold water runoff during construction. Generally, a water containment system is designed to allow for an influx of water holding the various pollutants, particles, and objects and the outlet of relatively clean water. The water is clean relative to the amount of pollutants, particles, and objects found in the water containment system. Such water containment systems are usually not designed to purify the water exiting the system.
The rate of water influx and outlet is important to the design of a water containment system to insure the water containment system does not overflow, thereby sending the various pollutants, particles, and/or objects into the surrounding environment, or dry up, potentially clogging the outlet system and/or sending the various pollutants, particles, and/or objects into the area where the relatively clean water was being sent. Therefore, it is important to know the flow rate of the water exiting the system. The current invention provides for an apparatus and method for removing relatively clean water from a water containment system.

The present invention is a water skimmer for removing water from a water containment system through a water outlet. The water skimmer operates by limiting the movement of water from the water containment system to the water outlet using uniquely sized and numbered water apertures. The water in the water containment system A moves into and through the water skimmer 100, into a water outlet 5, and out of the water containment system A, as shown in
The water skimmer 100 as seen in
The water skimmer 100 may comprise float material 7, as seen in
The one or more air apertures 11 are inlets through which air passes to facilitate the movement of water through the water apertures 3 which are located on the side of the skimmer generally opposite said one or more air apertures 11. For example, the one or more air apertures 11 are located on the top of skimmer such that the air apertures 11 are at or above the surface of the water level 2 of the water containment system and the water apertures 3 are below the surface of the water level 2 of the water containment system such that the head 13 of water is between approximately 1.5 and 6 inches deep above the water apertures 3. The flow of water through the water apertures 3 is gravity fed and may additionally include pumping or suction, not shown, to further facilitate the flow of water. A gravity fed water skimmer will be known to those having ordinary skill in the art as referring to a device using the characteristic of water to move from a high point to a lower point without outside energy being applied to the system to move the water. In this case, the water moves through the water apertures 3, into the conduit 1, then to a water outlet 5 which is generally positioned to be lower than the conduit as seen in
The water outlet 5 is any structure which allows the water to move from its position in the conduit 1 to an area outside the water containment system. For example, in
The water skimmer 100 may include a connector 15 which is adapted to engage the water outlet 5 as seen in
The water skimmer 100 may further include one or more supports 17 integral to or in communication with said conduit 1 as seen in
In one embodiment, water skimmer 100 may comprise a cover, not shown, adapted to be adjustable to cover or uncover one or more of the water apertures 3 such that water may or may not, respectively, flow through said water aperture 3. The cover may be any material or structure which allows one or more water apertures 3 to be securely covered or uncovered. Examples of such material or structure are, but are not limited to, neoprene or rubber sleeves or PVC, ABS or HDPE structures. The one or more water apertures 3 are securely covered or uncovered if the status of the one or more water apertures 3 as covered or uncovered does not change during the use of the water skimmer 100. In one embodiment, the cover is a rubber sleeve (not shown) fitted over the conduit 1 in such a way as to allow the sleeve to be positioned over one or more water apertures 3. The cover may be adapted to simultaneously cover or uncover the one or more air apertures 11. In another embodiment, the cover is a rigid structure which mechanically engages the conduit to cover one or more water apertures 3 and/or air apertures 11.
The water apertures 3 are adapted to allow water into the conduit 1 at a predetermined rate. The predetermined rate is equal to the flow rate of water through one predetermined water aperture 30. The flow rate of water is the amount of water passing a point within a period of time where a known head 13 of water is above said point. “One predetermined water aperture” 30 refers to a single aperture of set size. The size of a predetermined water aperture 30 is different for a selected predetermined rate. For example, one predetermined water aperture 30 one inch in diameter has a selected predetermined rate of one, while one predetermined water aperture 30 two inches in diameter has a selected predetermined rate of 2. The current invention comprises one or more water apertures 3 having a size less than the size of the predetermined water aperture 30 to create a flow rate of water through said water apertures 3 at or about the flow rate of water through one predetermined water aperture 30. For example, to create a selected predetermined flow rate of 1.25, which would usually require one predetermined water aperture 30 of 1.25 inches in diameter, the current invention comprises one water aperture 3 of 0.75 inch in diameter and one water aperture 3 of one inch in diameter. The size and number of water apertures 3 may be adapted to create a flow rate of water through said water apertures 3 at or about the flow rate of water through one predetermined water aperture 30. Examples of differing sizes and numbers of water apertures can be found in Tables 1-3 and
In one embodiment, the conduit 1 comprises four water apertures 3 that are 0.5 inches in diameter to provide a flow rate of water at or about the flow rate of a one inch predetermined water aperture 30 as shown in
In one embodiment, the conduit 1 comprises nine water apertures 3 that are 0.5 inches in diameter to provide a flow rate of water at or about the flow rate of a one and one-half inch predetermined water aperture 30 as seen in
In one embodiment, the conduit 1 comprises four water apertures 3 that are 1.0 inches in diameter to provide a flow rate of water at or about the flow rate of a two inch predetermined water aperture 30 as seen in
In one embodiment, the conduit 1 comprises nine water apertures 3 that are 1.0 inches in diameter to provide a flow rate of water at or about the flow rate of a three inch predetermined water aperture 30 as seen in
Other nonexhaustive embodiments of the size and number of water apertures 3 can be seen in Table 4 and the corresponding Figures.
The current invention includes a method of removing water from a water containment system by providing a water skimmer having a conduit, which may be comprised of one or more conduit structures, and float material. The conduit has a defined height and defines one or more air apertures and one or more water apertures. The float material and height of the conduit may be adapted to maintain between approximately a 1.5 inch to 6 inch head of water above the water apertures while maintaining the air apertures at or above the water level of said water containment system. The number and size of the water apertures affects the flow rate of water through the water skimmer. The number and size of the water apertures are adapted to provide a flow rate equal to the predetermined rate of one predetermined water aperture as discussed above. The method of the current invention includes connecting the water skimmer to a water outlet. The water outlet may be a pipe. The water skimmer is placed into the water containment system allowing water from said water containment system to move through the water apertures to said water outlet. The flow of water through the water apertures may be gravity fed and may additionally include pumping or suction to further facilitate the flow of water. The water outlet is in communication with an area outside the water containment system.
In one aspect of the invention, the water outlet is adapted to move vertically in relation to said water level such that the water outlet does not impede the ability of the water skimmer to remain at or about the surface of the water level of the water containment system such that the head of water is substantially consistently between approximately 1.5 and 6 inches deep above the one or more water apertures and the one or more air apertures are at or above the water level as described herein.
Certain modifications and improvements will occur to those skilled in the art upon a reading of the foregoing description. All such modifications and improvements of the present invention have been deleted herein for the sake of conciseness and readability.
Numerous other aspects of embodiments, embodiments, features, and advantages of the present invention will appear from the description and the accompanying drawings.
