CCTV inspection as an important part of ensuring the reliability of sewer network operation

Pipeline surveys with cameras (CCTV) are carried out with a focus on different objectives – mention, first of all, surveys related to condition assessment for specific technical rehabilitation projects, acceptance surveys afterward, and ongoing inspections of the network carried out to control its current technical condition. These objectives dictate a different approach to the surveys, as a result of their required accuracy, thus dictating appropriate equipment solutions. A derivative of this is the adequate recording of test results and their interpretation. No less important are issues of qualification of research participants. These issues are compounded by changes in equipment solutions occurring in recent years.
The presentation will cover the main principles of conducting CCTV inspections in sewers in the aspects mentioned above, along with the basic equipment solutions used in practice.
