Most parts of sewer and drain line systems can be easily mapped by surveying the inverts of manholes and connecting the obvious pipe segments. In order to locate and identify the remainder of the system, UtiliSurvey uses a radio frequency sonde mounted onto video inspection equipment. This enables technicians to simultaneously inspect and map pipe segments, as well as laterals and manholes. The collected video and pipe data are digitally recorded on a DVD and the location is surveyed via RTK-GPS.
