Abstract
A septic tank is constructed from top and bottom shells. The top and bottom shells are nestable within like top and bottom shells in order to allow greater numbers of septic tanks to be shipped one a cargo truck or railroad car. In a preferred embodiment, both the top and bottom shells have peripheral flanges that interlock together. The septic tank is assembled at its sight of intended use by placing the top and bottom shells together, inserting a gasket material between the interlocking peripheral flanges, and affixing a plurality of clips over the interlocking peripheral flanges to hold the top and bottom shells together. Preferably, the peripheral flanges serve the function of an integral antifloatation collar for the septic tank. The antifloatation collar increases the cross sectional area of the septic tank over which soil is applied, and allow the tank to be firmly held in the ground without the use of an anchor or ground screw.
