The inspection of sewer networks is an essential task to ensure their proper operation and avoid the risk of damage. Whether it's to prevent blockages, detect cracks or assess the general condition of the infrastructure, visual inspection helps identify anomalies and anticipate any necessary work.
In this context, standard NF EN 13508-2 defines a precise methodological framework for the inspection and coding of anomalies observed in wastewater and stormwater drainage systems.
The Roview2inspection robot developed by Multinnovis an innovative, high-performance solution in this field. But does it meet the requirements of this standard? Let's take a closer look.
What is NF EN 13508-2?
Definition and objectives
The NF EN 13508-2 standard, originally published in 2003 and amended in 2011, is a European reference for sewer system inspection. It establishes a standardized method for coding defects and pipe characteristics, in order to standardize the assessment of pipe condition.
It applies to sewage systems located outside buildings, which operate mainly by gravity. This includes pipes carrying domestic and industrial wastewater, as well as rainwater, to treatment plants or receiving watercourses.
Why is this standard important?
The main aim of this standard is to ensure consistent interpretation of observations made during visual inspections. By using a standardized codification, professionals can :
- Describe pipe defects (cracks, obstructions, roots, corrosion, deformations, etc.) accurately and consistently.
- Facilitate decision-making for infrastructure maintenance and rehabilitation.
- Compare inspections over time to track changes in network condition.
- Improve communication between the various stakeholders (local authorities, wastewater treatment companies, network managers, etc.).
Standard-compliant inspection methods
Standard NF EN 13508-2 requires television inspection as the preferred method. This means that networks must be inspected using cameras mounted on robots.
or inspection vehicles, capable of capturing detailed images and pinpointing any anomalies detected.
This is where the Roview2 from Multinnov comes into play.
How does Roview2 meet the requirements of the standard?
The right solution for TV inspections
The Roview2 is a TV inspection robot specially designed for wastewater networks. Unlike conventional solutions, this autonomous robot is capable of moving on land as well as water, enabling it to explore pipes inaccessible to traditional vehicles.
Its high-definition 4K camera, mounted on a pivoting turret, guarantees crisp, detailed image capture, essential for meeting the visual coding requirements of NF EN 13508-2.
Technical capabilities in line with standard requirements
The Roview2 incorporates several features that are essential for standard-compliant inspections:
- High-resolution 4K camera : detects even the smallest defects (cracks, deposits, root intrusions, etc.).
- Motorized 360° horizontal and 180° vertical turret : Ensures complete pipe inspection, with no blind spots.
- Precise distance-measuring system : Thanks to an encoded wheel, the Roview2 is able to accurately measure distance travelled and pinpoint anomalies - a key requirement of the standard.
- Moving over water : Unlike conventional robots, the Roview2 can operate in partially flooded pipes. This feature is particularly useful for inspecting gravity sewer systems.
- Real-time transmission : The operator receives live images and data, enabling immediate analysis of detected faults.
Adapting to tough conditions
The environment of wastewater pipes is often hostile: humidity, lack of light, solid deposits, partial flow... The robustness of the Roview2 enables it to adapt to these extreme conditions and carry out precise, uninterrupted inspections.
What's more, its powerful LED lighting ensures optimum vision even in the darkest ducts.
The importance of Roview2 for the sanitation industryt
The use of Roview2 by companies and local authorities managing wastewater systems is a considerable advantage:
- Reliable, accurate inspections : thanks to its 4K camera and precise positioning system, the Roview2 provides reliable, usable data for infrastructure maintenance and rehabilitation.
- Reduced intervention costs : The use of an autonomous inspection robot avoids risky human intervention and limits the need to completely dry out ducts before inspection.
- Time-saving : Thanks to its autonomy and ability to travel on water, the Roview2 reduces inspection times, which is essential for optimizing maintenance operations.
- Improved network durability : By enabling regular, preventive monitoring, it helps prevent failures and extend the life of wastewater infrastructure.
Standard NF EN 13508-2 establishes an indispensable framework for the inspection of sewer networks. By imposing strict criteria for the description of anomalies and the use of television inspection, it enables more efficient and transparent management of underground infrastructures.
The Roview2thanks to its advanced technical features, fully meets the requirements of this standard. Its 4K camera, unique mobility on land and water, LED lighting and real-time transmission make it the ideal solution for visual inspections to European standards.
By adopting the Roview2sanitation professionals have a high-performance, reliable, standards-compliant tool at their disposal, guaranteeing high-quality inspections and helping to optimize drainage networks.
