Abstract
Abstract A compact nesting septic tank package comprising a plurality of prefabricated elongate septic tanks having one open end and successively diminishing cross-sectional areas with the tanks being successively and removably positioned one within the other. The inner septic tank preferably has a plurality of conduits positioned therein in a nesting package arrangement for use in forming sewage conduits. A sewage disposal system may be formed from the package comprising vertically extending, tandemly arranged septic tanks of diminishing cross-sectional areas to provide the desired capacity. The septic tanks include closures at the upper ends and are closed at the lower ends by being mounted on a base member. The system includes conduits interconnecting the septic tanks and arranged for conveying sewage from a source to the tanks, between the tanks and to an absorption field. Preferably, the conduits are so disposed for conveying the sewage throughout the absorption field.
