Lateral cameras can also be used to identify sources of I/I, solids accumulation, root infiltration, pipe defects, and the overall structural condition of the laterals. Lateral systems are also the preferred inspection method to verify the absence of cross bores resulting from horizontal directional drilling (HDD) operations.
Not only are more laterals accessible with improved technology, but laterals can be located with GPS to update mapping and GIS records. Tele-Vac conducts lateral inspections in accordance with NASSCO’s Lateral Assessment Certification Program (LACP). In certain conditions, pushrod CCTV cameras are the preferred inspection method. All our push-rod cameras have a sonde attached which allow the technician to locate position and depth. Electronic sewer and tile locating can prove to be the cheapest preventative measure for finding buried lines prior to any type of excavation. See our Cross-Bore inspection for more details about the lateral launching equipment used by Tele-Vac.
