WRc describes CCTV inspection as a tool for structural condition and operational serviceability. Agree deliverables against the decision the survey must support before comparing prices, including available plans and earlier reports.
Prepare the drain and access
Establish access and visibility along the camera route. Deposits, standing water and obstructions can limit inspection. Agree any preparation cleaning or clearance as a defined task with its own scope and cost.
Confirm chamber and shared-land access, accounting for traffic, occupancy and unusual substances. Keep the work area available, but do not enter chambers or attempt difficult cover lifting to prepare the visit.
Read the findings in context
Require run references, direction, inspected extent and findings. Record where the camera stopped and why. Without location references, footage is difficult to translate into an identifiable repair package.
Separate pipe defects from deposits and operational restrictions. Roots may conceal surrounding construction and require removal followed by inspection. A visible obstruction does not establish the condition of the unexamined section beyond it.
A camera does not automatically reveal surrounding ground or demonstrate every joint is watertight. Commission any additional test or investigation separately where the question requires it.
Turn evidence into an action plan
Link recommendations to observed conditions. Next steps may include cleaning, local repair, lining or replacement assessment, or improved access. Retain the connection between each proposal and its survey finding.
Keep repair evidence with the original survey so future managers can identify the location, finding and completed action without reconstructing the history.
Frequently asked questions
Can a survey be completed through a blocked drain?
An obstruction may prevent movement or visibility. Agree preparation and keep any remaining unexamined section explicit in the coverage record.
Does visible damage mean the whole drain needs replacing?
No. Repair choice depends on extent, surrounding condition and site constraints. Evidence may support a local intervention rather than whole-run replacement.
What should I receive after the survey?
Agree footage, a written report, referenced locations and recommendations matching the brief. The deliverable must show both completed coverage and limitations.
