A system for locating an underground utility having a conduit is disclosed. The system includes a fiber optic cable coupled to the conduit. The fiber optic cable includes at least one core and a plurality of strain sensors distributed along a length of the at least one core. A processing device is disposed in selective communication with the fiber optic cable. The processing device is configured to receive signals from the plurality of strain sensors. A service station is communicably coupled to the processing device. The service station is configured to determine a shape of the fiber optic cable. Further, the service station is configured to determine a position of the conduit relative to a predefined reference frame fixed with the service station based on the shape of the fiber optic cable.
