The septic tank of the subject invention can be provided in kit form, and preferably comprises a tank lid, a tank bottom, a pair of opposing side walls, and a pair of opposing end walls having a tank flow outlet and a tank flow inlet, where a flange is affixed within the tank flow outlet and the tank flow inlet. The tank lid comprises a pair of lid openings, which are covered by hatch covers.
