Description:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to waste water control and, more specifically, to a septic system drainage field.
The septic system is a natural method of treatment and disposal of household wastes for those homeowners who are not part of a municipal sewage system. A septic system works by allowing waste water to separate into layers and begin the process of decomposition while being contained within the septic tank. Bacteria, which are naturally present in all septic systems, begin to digest the solids that have settled to the bottom of the tank, transforming up to 50 percent of these solids into liquids and gases.
When liquids within the tank rise to the level of the outflow pipe, they enter the drainage system. This outflow, or effluent, is then distributed throughout the drain field through a series of subsurface pipes. Final treatment of the effluence occurs here as the soil absorbs and filters the liquid and microbes break down the rest of the waste into harmless material. The drainage field in an often overlooked aspect of the septic system, yet it is more important than the tank for the proper operation of the entire system.
The present invention is a new drain field design for a septic system filter apparatus for filtering waste water as it travels from a septic tank to a septic field. Unlike septic system drain fields of prior art, the septic system drain field of the present invention does not require piping through the chambers and in turn improves the distribution of the waste water.
The drain field design comprises a header pipe leading from the septic tank to a series of chambers. A second header pipe is connected to the opposite end of the chambers. The unique chamber assembly of the present invention consists of a housing having a base forming support, top cover plate, end plate, a channel having drain apertures extending the length of said channel wall (both sides) and when necessary inner support members.
Each chamber assembly is interlocked end to end forming a desired length of the drain field and nominally spaced apart side to side forming a desired width of the drain field. The length and width of the drain field varies based on local code and project specification.
By eliminating the inner piping through the chamber typical of prior art, the septic system drain field of the present invention provides improved waste water distribution and in turn maximizes the efficiency of the drain field and reduces maintenance cost for the entire system.
2. Description of the Prior Art

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The following discussion describes in detail one embodiment of the invention (and several variations of that embodiment). This discussion should not be construed, however, as limiting the invention to those particular embodiments, practitioners skilled in the art will recognize numerous other embodiments as well. For definition of the complete scope of the invention, the reader is directed to appended claims.
FIG. 1 is an illustrative view of the present invention 10 in use. The present invention is a septic system drain field 10 apparatus for filtering waste water as it travels from a septic tank 18 to a septic field 22 . The drain field 10 design comprises a plurality of interlocking dominator chambers 12 that are subterraneanaly connected in end-to-end fashion to provide extended leeching lines 24 of a desired length. A plurality of leeching lines 24 are disposed side by side in parallel relation with one another. Waste water from the dwelling 20 is introduced to a septic tank 18 then gravity fed to the septic system drain field 10 via a front header pipe 14 and delivered into the leeching lines 24 through the first dominator chamber 12 thereof. An end header pipe 16 is in communication with the last dominator chamber 12 of each leeching line thereby creating a relatively closed drain field 10 wherein waste water escapes through a plurality of drain holes disposed in the dominator chambers and will redirect effluence to other leeching lines 24 in the event that one becomes clogged.
FIG. 2 is a perspective view of the dominator chamber 12 of the present invention including a housing 26 having walls 30 on either side of an effluence channel 32 and base support feet 28 disposed on the bottom ends of the walls 30 . A top cover plate 34 encloses the effluence channel 32 and an end plate 36 is secured to the ends of the first and last dominator chamber 12 of each leeching line and includes a recess 38 for receiving a header pipe therein. A plurality of drain holes 40 are disposed in the effluence channel 32 for the egress of effluence therefrom and a plurality of longitudinal slots 42 are further included in the walls 30 to aid in the dispersion of the waste water into the septic field.
FIG. 3 is a perspective view of the dominator chamber 12 of the present invention including a housing 26 having walls 30 on either side of an effluence channel 32 and base support feet 28 disposed on the bottom ends of the walls 30 . A plurality of drain holes 40 are disposed in the effluence channel 32 for the egress of effluence therefrom and a plurality of longitudinal slots 42 are further included in the walls 30 to aid in the dispersion of the waste water into the septic field.
FIG. 4 is a perspective cutaway view of the dominator chamber 12 including a housing 26 having walls 30 on either side of an effluence channel 32 and base support feet 28 disposed on the bottom ends of the walls 30 . A plurality of drain holes 40 are disposed in the effluence channel 32 for the egress of effluence therefrom and a plurality of longitudinal slots 42 are further included in the walls 30 to aid in the dispersion of the waste water into the septic field. The end plate 36 is secured thereto to accommodate a header pipe.
FIG. 5 is a perspective view of the optional inner supports 44 of the present invention. The present invention provides optional inner support members 44 for placement within the housing 26 . The separate inner supports 44 are used as necessary, and may not be required in an application where support can be built into the chamber.
FIG. 6 is a detailed view of the optional inner support 44 of the present invention. The present invention provides optional inner support members 44 for its drain field design. The drain field design comprises a housing having a base forming support, walls and top cover plate, end plate, and a channel having drain apertures extending the length of the channel wall (both sides) and each unit lockable to other units having header pipes at both ends. The optical inner support members 44 are used as necessary, and may not be required in an application where support can be built into the chamber.
FIG. 7 is a detailed view of the end plate 36 of the present invention. The present invention provides end plate members 36 for its drain field design. The drain field design comprises a housing 26 having a base forming support, inner pipe and top support, end plate members 36 and a channel having drain apertures extending the length of said channel wall and each unit lockable to other units having header pipes at both ends. The end plate 36 has a recess 38 to accept a header pipe therein.
FIG. 8 is a detailed view of the end plate 36 of the present invention. The end plate 36 is secured to the open end of each dominator chamber at the end of the leeching line. An extruded retaining flange 46 conforming to the shape of the housing of the dominator chamber is offset from the edge thereof for securing the end plate 36 to the chamber. A recess 38 is provided for connection to a header pipe and the passage of effluence therethrough.
FIG. 9 is a detailed view of the cover plate of the present invention. The present invention provides a top cover plate member 34 for its drain field design. The cover plate 34 resides on the housing 26 to enclose the effluence channel 32 .
FIG. 10 is a sectional view of the present invention 10 in use taken from FIG. 1 as indicated. Shown are six parallel leeching lines 24 , each comprising a plurality of interlocking dominator chambers 12 attached end-to end with end plates 36 disposed on the ends of each leeching line 24 . Recesses 38 in the end plate 36 are in communication with header pipes (end header pipe 16 is shown) and the respective effluence channel 32 to allow for the passage of effluence therethrough. Once installed, the septic system drain field 10 is covered by native backfill 48 , top soil 50 and established vegetative cover 52 . The effluence leeches into the septic field 22 through a plurality of recesses disposed in each effluence channel 32 where it continues the process of decomposition. The advantage of having header pipes on both ends of each leeching line 24 is to provide an alternate point of entry for effluence in the event of a clog thereby enabling the leeching line 24 to remain functional even if compromised.
FIG. 11 is an illustrative view of the present invention 10 . Shown are six parallel leeching lines 24 , each comprising a plurality of interlocking dominator chambers 12 attached end-to end. The arrows indicate possible flow of effluence within the system from the septic tank 18 . The advantage to having header pipes 14 , 16 on both ends of each leeching line 24 is to provide an alternate point of entry for effluence in the event of a clog thereby enabling the leeching line 24 to remain functional even if compromised.
It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claims, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
