A cover system for septic tanks adapted to be attached to the a septic tank and provide access for repair and maintenance. The assembly includes a base which is embedded into the concrete and provides a seal between the concrete and the base. A pipe member is joined to and sits atop the stationary base member. A wrap made of high density polyethylene surrounds the pipe and covers its corrugations to reduce outside forces upon the pipe. Finally, there is a top cover which is designed to engage the top of the pipe. Additionally, a channel is provided to catch the edge of the pipe and a seal is provided to prevent leakage between the pipe and cover.
