Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation-in-part of U.S. application Ser. No. 11/235,405 filed on Sep. 26, 2005.

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a septic system for handling household waste water. More particularly, the present invention relates to a septic system that can expand the amount of filtering material around or adjacent to a conventional new, existing septic gallery, or provide a new unitary gallery to expand a septic system capacity.
2. Description of the Related Art
Septic systems are well known in the art. One such septic system is disclosed in U.S. Pat. No. 4,759,661 to Nichols, et al. (hereinafter “Nichols”). Nichols discloses a leaching system conduit made from a thermoplastic member having lateral sidewalls with a number of apertures. The thermoplastic member is an arch shaped member in cross section and has the apertures for the passage of liquid therethrough. The lateral sidewalls also have a number of corrugations formed in a rectangular shaped manner.
Such septic systems are deficient in their operation. First of all, zoning ordinances for certain sized homes require larger septic systems. Such larger septic systems may not fit on the desired building lot. A large number of bedrooms in a new home construction require according to some zoning laws that a certain sized septic system be used or that the certain sized septic system have a predetermined volume. This can be problematic under certain circumstances because the desired septic system may not fit in a certain lot and the new home owner may be limited to only a second sized septic system that is less than desired. With this smaller septic system, the new home builder thus must reduced the size of the new home. Secondly, in other circumstances homeowners may wish to expand the capacity of the septic system in a retrofit manner from a first size to another second size to accommodate a larger home.
However, a known problem in the art is that the under this arrangement, the second sized larger septic system like Nichols' leaching system will require the homeowner to excavate the leaching system and remove the leaching system. Thereafter, the homeowner will have to remove additional soil and dirt and then insert a new second sized larger septic system. Thereafter, the homeowner may have to perform additional work to the home to accommodate the home with this replacement and further obtain all of the requisite permits and variances to the zoning laws.
Accordingly, there is a need for a septic system that increases an amount of filtering medium so smaller septic systems may be used with larger homes thus maintaining an amount of effluent entering the septic system. There is also a need for a septic system that does not require replacement of the entire septic system for an upgrade. There is also a need for a septic system that has a more productive filtering. There is a further need for a septic system that has an attachment that can expand a complementary filtering area of the septic system. There is a further need for a septic system that is entirely unitary an has a smaller foot
There is also a need for such a system that eliminates one or more of the aforementioned drawbacks and deficiencies of the prior art.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, there is shown a septic gallery 5 as is known in the art. The septic gallery 5 is preferably a container that is placed in a leaching field, such as ground or sand, and is utilized for drainage of effluent. Effluent is a term commonly used for waste materials such as liquid and solid industrial refuse or liquid and solid residential sewage that flows out of a source and is discharged into the environment. The effluent is carried from a source such as a bathroom to the septic tank, then to the leaching field for dispersion, diffusion, or percolation, into surrounding soil.
Known pipes carry the effluent discharge and release the material into a chamber, or vault such as the septic gallery 5. The gallery 5 as is known will have a number of perforation or holes leading from the septic gallery 5. The gallery 5 is usually buried in a trench to facilitate dispersion of the effluent into the soil. All of the solid effluent stays in the septic tank, and only the liquid and liquid effluent diffuses into the sand.
In some systems, the gallery 5 is defined by a large diameter perforated conduit. In other systems, the gallery 5 is perforated to provide direct dispersion into the sand. The effluent is then dispersed into the soil either through the soil serving as the floor of the gallery 5 or, when effluent accumulates in the gallery, through passages in side walls thereof.
One known problem in the art is that the interface between the gallery 5 and the ground only allows for a finite flow or dispersion rate of liquid waste from the gallery to the soil or sand on the other side. The inventor of the present invention has recognized this known problem and has solved the problem with the present invention that has a number of unexpected benefits that increase a capacity for liquid waste of the gallery 5, and allows an increased amount of liquid and liquid waste to diffuse into the ground.
A prior art septic gallery 5 is commonly concrete or formed of plastic resin material and corrugated for strength. This septic gallery 5 is formed in sections that are mated to vary the effective length of the leach field. Sometimes multiple septic galleries 5 are connected to one another to increase the length and capacity of the leaching field, for example a home.
Referring now to FIG. 2 a, there is shown the septic gallery 10 of the present invention buried beneath the ground. The septic gallery 10 is preferably connected to an effluent source, and has a first conduit 12 or pipe that is connected to a septic tank or pump chamber. In one embodiment, the septic gallery 10 has a four foot width although galleries can be provided in a variety of standard and/or conventional sizes to accommodate homes and or properties of differing sizes. The septic gallery 10 preferably has a first conduit 12 on a first side 14 of the gallery, and a second conduit 16 on a second side 18 of the gallery. The effluent is in a liquid form and preferably enters the gallery 10 from the first conduit 12 and the second conduit 16 to fill the gallery over time to capacity. Capacity is the number of gallons of effluent and depends on the size of the residence or waste source above ground. After a period of time, prior art galleries becomes full with liquid effluent, and must be replaced.
What is desirable is a device that may increase a capacity of the septic gallery while liquid effluent is not be stored therein. Instead, the liquid effluent is diffused to the surrounding environment to percolate through ground for filtering thereof. Most preferably, the present invention achieves this need in an unexpected manner.
The gallery 10 has a first appendage 20 on the first lateral side 14 of the gallery 10. Preferably, the first appendage 20 contacts the ground or sand in the ground contacting side, and also communicates with the first conduit 12 on the first side 14 of the gallery opposite the ground contacting side. The surrounding earth or sand presses appendage 20 to gallery 10. Alternatively, the appendage 20 and the gallery 10 may be formed as one integrated structure or as separate discrete pieces. The first appendage 20, in one embodiment, may be permanently connected to the septic gallery 10 by a connector. Alternatively, the first appendage 20 may be a modular member that is removably connected to the septic gallery 10, for easier replacement thereof.
Preferably, the first appendage 20 has a number of shaped members to permit enhanced diffusion of the effluent into the ground. The first appendage 20 has any acceptable shape to permit diffusion into the ground from the gallery 10 in a rapid manner. Preferably, the first appendage 20 has a number of three-sided or triangular shaped members generally represented by reference numeral 22 with each having an apex 24 and a base portion 26. The three-sided members could have a rounded tip. The triangular shaped members 22 collectively preferably form a baffle. Each member 22 is preferably a triangular member having two equal sides to form a substantially isosceles triangle. However, each member 22 can be a substantially equilateral triangle in which each angle includes approximately 60 degrees. Still further, each member 22 may be any three-sided member. Each member 22 is made from a material capable of withstanding the environment of the septic tank and gallery, such as, for example, a plastic resin material that would include resilient thermoplastic, polycarbonate, polyvinyl chloride (PVC), achrilonitride-butadiene-styrene (ABS), polyurethane, or acrylic resin.
In an alternative embodiment, a septic system 60 is shown in FIG. 7. Septic system 60 has a plurality of appendages 65 that each have a flattened tip to form a trapezoid, instead of an apex as shown in the previous embodiment. The plurality of trapezoidal shaped appendages 65 collectively form a baffle 70. Appendages 65 are on opposite sides of gallery 75 to effect the diffusion of effluent. Appendages 65 each have a pattern of holes therethrough to expedite the passage of the effluent into the surrounding soil. The dimensions of each appendage vary and can be from one foot to two feet long. The width of each appendage at its bases can be approximately 4 inches and taper to approximately 3 inches. Similarly, the length of baffle 70 can vary to meet the necessary septic system capacity.
In one non-limiting embodiment, the base portion 26 has a width of about one foot. A diffusion space 28 is formed between a first triangular member 30 and a second triangular 32 member of the baffle 22. The diffusion space 28 is also triangular shaped and is preferably allowed to fill in with an acceptable ground contacting material such as sand, gravel, or any combination thereof, for diffusion. Likewise, a second diffusion space 28 is formed between the second triangular member 32 and a third triangular member 34. This structure continues along the length of the septic gallery 10. A similar configuration is possible for the trapezoidal shaped appendages, in which successive trapezoidal shaped appendages have a trapezoidal or triangular space therebetween.
Referring to FIG. 3, there is shown a frontal view of the baffle with the diffusion spaces 28. The baffle 22 has a number of apertures 36 thereon. The liquid effluent preferably traverses through the apertures 36 and then diffuses into the soil, sand, gravel, or ground. The baffle 22 preferably increases a surface area of the lateral side of the first appendage 20 of the septic gallery 10 to allow an increased amount of liquid effluent to escape from the first appendage, and traverse through the apertures and for diffusion to the sand, or ground.
Referring to FIG. 4, there is shown a cross sectional view of the first appendage 20 along line 4-4 of FIG. 2 a. The base portion 26 of each triangular member of the baffle 22 has the apertures 36 in a configuration.
Preferably, the septic gallery 10 also has a second appendage 38 located on a second side 16 of the septic gallery 10 as shown in FIG. 1. Additionally, the first and the second appendages 20, 38 may form modular members to retrofit to an existing septic gallery 10 to increase a capacity thereof. Appendages 20 and 38 can be fabricated to accommodate existing and new galleries. Spaces between first and second appendages 20 and 38, respectively, can be filled with mason sand or any such material that can accept the fluid. Referring to FIG. 2 b. gallery 10 could also have an additional third appendage 39 affixed to an end thereof to provide diffusion capability on three sides.
Referring to FIGS. 5 and 6, a second embodiment of an appendage system 40 of the present invention, is shown. System 40 has two appendages 42 and 44 that are abutting each other. Each appendage 42 and 44 can have any number of triangular elements 46 to form a baffle 48. Each baffle 48 has numerous apertures 54 to allow for passage of effluent into leaching field. Triangular elements 46 can have rounded tips 50 to further increase the surface area of diffusion of liquid into the soil 52 in the leaching field. Baffle 48 preferably increases a surface area of the lateral side of the first appendage 42 and 44 to allow an increased amount of liquid effluent to escape from the appendages and channel 56, and traverse through the apertures and for diffusion to the sand, or ground.
In a third embodiment of the present invention shown in FIGS. 8 and 9, septic system 80 has an entirely unitary structure. System 80 has a first baffle 85 and a second baffle 90. Each baffle has a plurality of trapezoidal appendages 95 and 100, respectively, integrally connected thereto to form a unitary trapezoidal configuration. A center channel 105 or conduit extends through the center of baffle 85 and facilitates the flow of effluent from source and through appendages 95 and 100. Channel 105 has a relatively small diameter relative to the dimensions of the appendages 95, to maintain a small footprint of the entire system without compromising dispersion capability. Channel 105 has a length of approximately from 6 feet to approximately 8 feet long. The height and width are approximately 1 foot to 3 feet depending upon the required capacity of the system. Appendages 95 and 100 are approximately 1½ feet to 2 feet in length away from channel 105. The overall with of conduit 105 together with appendages 95 and 100 is preferable from 4 feet to 6 feet. The unitary configuration permits a high capacity septic system with a small footprint thus minimizing the amount of land required for placement beneath or near a residence or building.
It should be understood that the foregoing description is only illustrative of the present invention. Various alternatives and modifications can be devised by those skilled in the art without departing from the scope of the present invention. Accordingly, the present invention is intended to embrace all such alternatives, modifications and variances.
