DWA rules and guidelines on the condition assessment in sewers

Coding, measurement and assessment of findings in pipes

The condition assessment and quantification (measurement) of inspection findings in drainage and sewer systems is of critical importance. If and when required, follow-up processes are initiated on the basis of related outcomes in accordance with applicable legislation or contractual provisions. Inspection results also create the basis for related evaluation processes. Their quality depends on appropriate preparation of relevant pipeline sections, but also on the suitability and reliability of utilized equipment as well as on the skillset and expertise of staff operating such equipment.
