ABSTRACT:
A system for detecting the location of an underground portion of a sewer line. A vibration or sound of a predetermined frequency is introduced into an accessible (e.g., above ground) portion of the sewer line. The vibration is allowed to propagate through the sewer line and into the underground portion of the sewer line. The location of the underground portion of the sewer is identified by sensing the vibration by means of a detector located at the ground surface or in an inserted "in ground" device above the underground portion of the sewer line.
