A subterranean coupler for slidably receiving a pipe therethrough and for coupling the pipe to a subterranean vessel. The coupler is mountable to a reinforcing grid prior to the coupler and reinforcing grid being cast in a concrete wall of the subterranean vessel. The coupler includes a longitudinally- extending axis and a cylindrical wall defined about the axis, the wall having an inner surface, an outer surface, and first and second ends. The coupler further includes a plurality of radially-extending, circumferentially-spaced engagement members integrally-formed with the outer surface. The engagement members are engageable with grid members of the reinforcing grid to mount the cylindrical wall to the reinforcing grid prior to casting. The coupler further includes pipe receiving means associated with the inner surface for slidably receiving the pipe therethrough and securing the pipe to the coupler, whereby the coupler may be releasably mounted to a reinforcing grid using the engagement members and then cast into a concrete wall of a subterranean vessel with the opposed first and second ends being exposed on respective opposite sides of the concrete wall, and a pipe may be slidably inserted through one of the ends into the pipe receiving means and thereby coupled to the subterranean vessel.
