Are you making the best-informed decisions following sewer CCTV surveys?
The inspection of our drains and sewers using cameras to determine their condition has been undertaken for the last 40 odd years. In its infancy, cameras were pulled through pipes and images were taken every metre to capture a view of the sewer. Today, the tools on offer to surveyors range from pole cameras and push rod systems to high-definition cameras mounted on tractor units, floats and even drones. While getting a CCTV camera into and along a pipe has largely been solved, the age-old problem of accurately and objectively interpreting what the images portray, in terms of asset condition assessing, is still a challenge yet of paramount importance.
WRc created the first image coding structure in 1980, which set out how to interpret key defects and then code them in a standardised format, resulting in the publication of the Manual of Sewer Condition Classification (MSCC) coding structure – now in its 5th edition. However, there remains a critical need to train surveyors in the interpretation of the captured footage and the correct method of coding and classifying defects observed, according to the MSCC. This knowledge ensures that a pipe’s internal condition can be consistently assessed and graded to prioritise repair and maximise investment and maintenance budgets.
It is essential that high-quality training at all levels is implemented and maintained to ensure the correct coding of defects, and that 
the generated reports represent an accurate condition assessment of the drain or sewer under review. Not only should operators seek the 0S19X certification in coding CCTV defects – all those working on an inspection are required to have a good understanding of how the survey was undertaken, how the codes were attributed and how the internal condition grade is calculated, as well as having knowledge of the standard itself to make the best-informed decision regarding any remedial action required.
To support the upskilling of the UK water industry, WRc is delighted to now offer one-day Awareness Training to people engaged in operational maintenance and sewer rehabilitation, as well as any engineers, consultants and regulatory officials who need to understand the application of the findings of a sewer CCTV survey. This course provides technical knowledge on sewer deterioration, the use of CCTV condition surveys and their use in sewer rehabilitation planning. Covering the key aspects of sewer inspection, attendees will gain an overview of the MSCC coding structure, how to recognise key features and the correct use of the codes and how the associated condition grading is generated using the WRc SRM methodology.
The next WRc Sewer CCTV Inspection Awareness training course will take place on 8th October in Swindon, and Online (live) spaces are also available for those unable to attend in person. Attendees will be trained by Wastewater Infrastructure specialist Peter Henley, who has worked on industry guides such as the MSCC, SRM and Drain Repair Book.
“The course will support consistency and up-skilling, which will then relate to reducing business risk on high grade defects within our sewer network, but also enable us to be less risk averse and therefore ensure money is spent where needed.”
