Definition - What does Manual Inspection mean?
Manual inspection refers to method of sewer pipe (or any other pipe) inspection that involves physical entry into the pipe to be inspected. This can be performed by having personnel physically enter the pipe while using a variety of tools to carry out the inspection, or it may entail the use of manually controlled CCTV cameras or similar remote equipment.
Trenchlesspedia explains Manual Inspection
Manual inspections, especially by CCTV equipment, allow pipe defects to be identified by trenchless means.
By manually inspecting pipes using CCTV cameras, the exact location of defects can be correctly identified and appropriate measures taken to repair only that section of pipe. This results in significant time and cost savings when compared to inspections via traditional excavations, which can sometimes be a trial and error exercise.
In addition, CCTV inspections can give a complete view of the sewer pipe which can potentially pick up defects that may not have been previously identified.
