Course “EN 13508-2 | Assessment of the Condition of Sewers Based on Visual Inspection (CCTV-2026)”
Urban water systems are essential infrastructures in modern societies, possessing significant asset value, and it is therefore necessary to ensure their sustainability — economically, financially, operationally, and structurally.
The visual inspection of sewers is a valuable tool for the effective management of urban water infrastructure. This course aims to promote the application of visual inspection techniques for wastewater and stormwater sewer systems, as well as to encourage the implementation of the standard EN 13508-2:2003 – Investigation and Assessment of Drain and Sewer Systems. Part 2: Coding System for Visual Inspection, which provides a standardized framework for the investigation and assessment of public sewer systems to support condition evaluation.
This standard defines a coding system for observations made during visual inspections, enabling the description of the internal condition of sewers, service connections, manholes, and inspection chambers. When deemed appropriate, it may also be applied to pressurized or vacuum systems, in accordance with the requirements of the managing authority. The coded information can be used for:
• assessing performance deficiencies within the context of developing rehabilitation plans;
• obtaining data to support maintenance planning activities, such as sewer cleaning programs;
• analyzing specific operational or maintenance issues.
This technical training course is designed to provide and strengthen knowledge on the visual inspection of sewer systems and on the application of the coding system defined in EN 13508-2 – Investigation and Assessment of Drain and Sewer Systems. It is intended for managers and technicians working in wastewater and stormwater systems, consultants, designers, inspection service providers, master’s and doctoral students, and other professionals interested in this subject area.
