Validation
A TRL is a measure to indicate the matureness of a developing technology. When an innovative idea is discovered it is often not directly suitable for application. Usually such novel idea is subjected to further experimentation, testing and prototyping before it can be implemented. The image below shows how to read TRL’s to categorise the innovative ideas.

Why?
As sewer systems deteriorate, rehabilitation is needed. Current rehabilitation decisions are based on CCTV inspection and subjective condition rating. Shifting from rating-based to performance-based asset management is needed.
How?
Novel self-learning algorithms combine data from existing and novel sensors to speed-up and objectify defect detection. Failure models are used to assess performance on key objectives to prioritise asset management activities.
When?
The focus for the coming years is to increase the ability and reliability of automated defect detection and to assess the performance implications of defects and failure. Concepts will be validated using a multi-sensor inspection prototype.
