Further providing, to earth-embedded surfaces of the integral conduit, elements for stabilization of the conduit within the earth; and providing, to upwardly directed, non-embedded surfaces of the conduit, a substantially flat surface including surface effects to aesthetically and functionally integrate into a surface environment associated with the conduit.
