A pipe support for mounting a pipe within a pipe-receiving aperture of a concrete container. The pipe support includes an annular anchor, a pipe seal and a removable closure. The annular anchor is for being cast in place within the concrete container surrounding the pipe-receiving aperture. The pipe seal has a flexible, reversible, generally frusto-conical outer portion extending axially rearward and radially inward from the anchor to a joint of the pipe seal. A flexible, reversible, generally frusto-conical inner portion extends axially forward and radially inward from the joint to a smaller diameter end of the pipe seal for receiving a pipe in a generally water-tight manner. The outer portion of the pipe seal can be reversed so that the pipe seal will extend out of the concrete container so that a pipe can be inserted therethrough from inside the container. Alternatively, the inner portion of the pipe seal can be reversed so that the pipe seal will extend into the concrete container so that a pipe can be inserted therethrough from outside the container. The pipe support also includes a removable closure closing the smaller diameter end of the inner portion for sealing in a watertight manner the pipe-receiving aperture of the concrete container when the pipe support is not used to mount a pipe.

[ What is claimed is:] [1.] A container made of cementitious material for use as part of a low pressure waste disposal system, the container comprising:A) at least one wall defining at least one pipe-receiving aperture;B) a pipe support positioned in said at least one pipe-receiving aperture and including,a sleeve having an annular anchor extending radially therefrom and being cast in place within the wall surrounding said at least one pipe-receiving aperture; anda pipe seal extending generally axially inwardly from the sleeve to a smaller diameter end for receiving a pipe in a generally water-tight manner, and including at least two flexible and reversible portions extending generally axially in opposite directions, whereby one of the at least two portions of the pipe seal can be reversed so that the smaller diameter end of the pipe seal extends either into or out of the concrete container when the pipe support is secured in the pipe-receiving aperture.
