Underground pipes and utilities are mapped by Quality Geophysics by inducing a signal onto a subsurface utility and tracing the signal as it moves along or within the utility. Inductive locating is a one-person operation used for locating a particular object or several points along a buried pipeline or utility cable. It is a method for locating unknown or lost conductors. Conductive tracing is a one-person operation used for tracing an individual pipe or cable (conductor) or for use when other conductors or metal objects are nearby. In addition, this method may also be used to trace nonmetallic pipe by connecting to a wire, plumber’s snake, or electrical fish tape. Quality Geophysics also screens for loaded (active) underground power lines.
