Abstract
Apparatus and a method for constructing a sewage drain field without a rock media. The drain field includes a plurality of lengthwise connected drain pipes suspended above the trench bottom within a channel formed by a plurality of elongated mesh-like channel forming members and in overlying relation to which assembly a porous, conforming length of sheet goods is mounted. As necessary, mesh-like end caps seal the ends of the channel forming members. Independently mounted filter elements may be used to filter the grey water and/or channel the grey water in lieu of the conduit.
Claims22
In a sewage disposal system apparatus for distributing effluent over the trenched surface of an effluent absorption bed and wherein no filler gravel is required comprising:
- (a) a lightweight soil supporting framework including a plurality of rib members coupled to one another to subtend an elongated hollow chamber having an open bottom and ends and mountable in a prepared trench;
- (b) a rot resistant, soil supporting first meshwork mounted over said assembled framework, the porosity of said meshwork being dense enough to prevent the infiltration of dirt and rock into the chamber, yet permit evaporation and the permeation of liquid therethrough;
- and
- (c) means suspended within said hollow chamber for receiving and distributing effluent over the surface of the absorption bed;
- (d) the effluent thereby being absorbed by the underlying soil and evaporating through the air and liquid permeable walls of said apparatus.
In a sewage disposal system apparatus for distributing effluent over the trenched surface of an effluent absorption bed comprising:
- (a) a lightweight soil supporting framework comprised of a plurality of rib members coupled to one another to subtend an elongated hollow chamber having an open bottom and ends and mountable in a prepared trench;
- (b) a plurality of rot resistant meshwork layers mounted over said framework and each other, the porosity of each layer becoming successively more dense to in combination support overlying soil between said rib members and prevent the infiltration of dirt and rock into said chamber, yet permit evaporation therefrom and the permeation of liquid therethrough;
- (c) a length of conduit suspended within said chamber having a plurality of holes formed through the walls thereof for receiving and distributing effluent over the length of said chamber;
- (d) a filter member suspended beneath said conduit for filtering solids from the effluent before being deposited on said absorption bed;
- and
- (e) means for removably mounting said filter member within said chamber, thereby permitting the changing of said filter member;
- (f) the effluent thereby being absorbed by the underlying soil and evaporating through the air and liquid permeable walls of said apparatus.
Modular drain field apparatus comprising:
- (a) a lightweight, rot resistant, soil supporting meshwork member having a plurality of perforations therethrough over a substantial portion of the surface area thereof and subtending a lengthwise hollow chamber having an open bottom and ends upon being buried in a prepared trench of an evaporation bed;
- (b) a pair of meshwork end caps mounted to the opposed ends of the chamber forming member;
- (c) a rot resistant cloth fabric permeable to air and water mounted over said chamber forming meshwork member for supporting the overlying soil between the perforations and preventing the infiltration thereof into said chamber;
- and
- (d) means permeable to water mounted within said lengthwise channel for receiving and conveying effluent along the length of said chamber and filtering solids therefrom as said effluent is deposited along the length of the chamber and allowed to be absorbed into the evaporation bed.
Modular drain field apparatus comprising:
- (a) a lightweight, rot resistant, soil supporting wire meshwork member having a plurality of perforations therethrough over a substantial portion of the surface area thereof and subtending a lengthwise hollow chamber having an open bottom and ends upon being buried in a prepared trench of an evaporation bed;
- (b) a pair of wire meshwork end caps mounted to the opposed ends of the chamber forming member;
- (c) a rot resistant cloth fabric permeable to air and water mounted over said chamber forming meshwork member for supporting the overlying soil between the perforations and preventing the infiltration thereof into said chamber;
- and
- (d) means permeable to water mounted within said lengthwise channel for receiving and conveying effluent along the length of said channel and filtering solids therefrom as said effluent is deposited along the length of the chamber and allowed to be absorbed into the evaporation bed.
In a sewage disposal system apparatus for distributing effluent over the trenched surface of an effluent absorption bed and wherein no filler gravel is required comprising:
- (a) a lightweight soil supporting framework comprised of a plurality of rib members coupled to one another to subtend an elongated hollow chamber having an open bottom and ends and mountable in a prepared trench;
- (b) a plurality of rot resistant wire meshwork layers mounted over said framework and each other, the porosity of each layer becoming successively more dense to in combination support overlying soil and prevent the infiltration of dirt and rock into said chamber, yet permit evaporation therefrom and the permeation of liquid therethrough;
- and
- (c) means suspended within said hollow chamber for receiving, filtering and distributing effluent over the surface of the absorption bed;
- (d) the effluent thereby being absorbed by the underlying soil and evaporating through the air and liquid permeable walls of said apparatus.
