In The Pipeline

The latest edition of Underground Utilities is available to read here

It includes a special feature on the CCTV industry, which gives a fascinating insight into how maintenance of underground utilities and pipelines have evolved thanks to the efforts of  a few good people at the forefront of engineering ingenuity. These systems have been transformed from hand-held black and white cameras that could only be used by men who risked their lives descending into large diameter pipelines holding red hot light bulbs, to sophisticated digital systems travelling on automatic transporters with panoramic cameras and internal LED lighting. Furthermore bespoke software packages can analyse hundreds of pieces of information and instantly send the results to the clients.
