New Launch: UNITRACC Module "Coding of Damage (Findings), Causes, and Consequences of Damage"!

Sep 27, 2023

New e-learning module of the course BE-07 Investigation and Inspection of Sewers and Pipelines now available on UNITRACC!

Summary of the Module

Investigation is the first of four basic measures in the context of integral urban drainage and sewerage management. It aims to provide the basis for assessing the performance of drain and sewer systems. The results obtained will serve as proof of complying with due diligence obligations and, in particular, as a basis for planning all operations, maintenance, and rehabilitation activities.

This module builds on the module Application of Coding Systems Using the Example of EN 13508-2 and introduces the process of coding defects for sewers and drains. In great detail, it presents the causes and consequences of defects and, in some cases, the defect mechanisms. It is part of the more extensive online training course BE-07 Investigation and Inspection of Sewers and Pipelines that will launch by the end of 2023.

The e-learning material consists of over 200 pages showing 223 images and 8 videos. 

The net learning time is approx. 10,5 hours.
