This system utilises industry standard static pole cameras that can be introduced into manholes, thus negating the need for confined space entry. The camera is manoeuvred into position to view the sewer to be inspected then records video and still images. This allows silt levels within the pipe to be ascertained as well as, within view structural defects to be reported. The information is transferred into our COPS system which produces an automated longitudinal section of the sewer, showing silt levels along its length. It generates an average silt level for that sewer length which is “traffic light” colour coded, allowing Clients to decide if there is indeed a need to carry out CCTV surveys. COPS also host relevant photographic evidence relating to the manhole including location, cover and manhole photographs.
