Large Diameter CCTV Surveys

Drain Doctor engineers use the latest drain inspection technology to conduct inspections of larger pipes. Our professional drainage surveys are capable of inspecting all the drains on your site to locate potential problems and give the condition of the infrastructure a thorough check. Large diameter CCTV surveys are much like our CCTV drainage survey but simply used to assess larger pipes such as the ones used in the sewer network. However, unlike normal CCTV drainage surveys, for large diameter, crawler cameras are used.

Our CCTV Drainage Surveys

There are numerous reasons why someone might require a large diameter drain survey and the service we provide depends entirely on the clients’ requirements. Our CCTV drainage service offering includes:

  • Checking the condition of the pipework infrastructure to identify any tree root ingress, leaks, wear and tear and blockages
  • Large diameter drain surveys for wider sewage pipes
  • Drainage and sewage mapping to find out where pipes run and who is responsible for them
  • Regular maintenance and upkeep as part of PPM work to prevent blockages and drainage issues
  • Pre-build surveys to ensure building work will not interfere with large diameter pipes
  • Pre-purchase surveys to ensure that a property’s pipework is up to scratch

Once we conduct a CCTV survey, we are then able to assist with everything from drain jetting to get drains flowing freely, to conducting and submitting reports to pass on to the relevant parties, for example, if there is an issue with large diameter sewage pipes then the Water Authority would need to be notified.
