US 4,824,287 A · Septic system

Abstract

In a septic system for handling household waste water, used vehicle tires are employed to form the septic tank and the leaching galleries. Vehicle tires sealed to one another and in combination with end caps provide a watertight and lighttight enclosure in the septic tank. An inlet conduit permits the influx of sewage into the enclosure while an outlet conduit allows egress of effluent from the enclosure via hydrostatic pressure. The drain field used with the system and also useful for other purpose has tires axially aligned forming an array with each tire defining an interior hollow chamber. A delivery conduit leading from the outlet conduit of the septic tank introduces effluent into the hollow chambers of the vehicle tires where it is allowed to seep therefrom into the surrounding earth through apertures in the walls of the tires. The tires in the drain field can be horizontally aligned or can be in a vertical stacking arrangement similar to the arrangement found in the septic tank.

Dependent claims

In a septic system,

A. a septic tank in which household wastes are treated, with solid wastes being decomposed by natural bacterial processes and settling in the tank while effluent flows from the tank into an adjoining drain field, comprising:
i. a plurality of vehicle tires forming a vertical stack of tires;
ii. means sealing said vertical stack of tires to form a watertight and lighttight enclosure therewithin;
iii. an inlet conduit in at least one of said plurality of tires for permitting influx of household wastes into said enclosure;
said inlet conduit adapted to be connected to a sewage line;
and
iv. an outlet conduit in at least one of said plurality of tires for permitting egress of effluent from said enclosure, said outlet conduit connected to a pipe leading to a drain field;
and
B. a drain field permitting effluent from said septic tank to seep into adjoining ground, comprising:
i. an array of vehicle tires in axial alignment, each of said vehicle tires in said array defining an interior hollow chamber;
ii. delivery means operatively connected to said array of tires for introducing effluent from a septic tank into said hollow chambers of said tires;
and
iii. means permitting effluent introduced by said delivery means into said hollow chambers of said tires to seep into adjoining ground.
