A septic tank structure having first and second lower tank members and a cover member supported on and forming a seal with respective upper ends of the tank members. The tank members each have a closed lower end, an open upper end, and side walls extending between the lower and upper ends to form a receptacle for receiving waste materials. The tank members have respective flat sides that extend in a substantially vertical plane and are placed together when the tank structure is assembled. The upper ends of the assembled tank members define an outer periphery having an oval shape. The cover member has a lower periphery, a manhole opening, and a steeply sloped wall portion extending between the lower periphery and the manhole opening. The lower periphery of the cover member has an oval shape that corresponds to the oval shape of the upper ends of the assembled tank members. A channel-shaped configuration on the lower periphery of the cover member enhances the seal between the cover member and the tank members. The side walls of the lower tank members are tapered outwardly from a lower end to an upper end to facilitate nesting of the tank members during transport and storage. A plurality of flat areas with raised thicknesses are provided on the side walls of the tank members to facilitate connecting a plurality of tank structures together in many different desired configurations. The lower tank members and cover member are preferably made of a polydicyclopentadiene thermoset material.
