Invisible but essential, the wastewater network is one of the pillars of our urban infrastructure. By 2025, monitoring and maintaining these installations will be an absolute priority for local authorities and network managers. To meet this growing demand, TV inspection cameras and inspection robots are being perfected every year, adapting to ever more complex and constrained environments. Among the most innovative solutions on the market, the Roview2designed by Multinnovhas established itself as an essential benchmark. So, how do you choose the right camera to inspect a sewer network? And why is the Roview2 the leader? Here are some answers.
Why inspect wastewater systems?
Sewerage systems collect, transport and sometimes treat wastewater and rainwater. These underground structures, often old and difficult to access, are exposed to multiple stresses: roots, corrosion, settlement, infiltration, obstructions and even collapse.
Regular inspections enable :
- Prevent breakdowns or overflows that could affect users or the environment,
- Check the general condition of pipes as part of a preventive maintenance policy,
- Evaluate the work carried out or establish a pre-renovation diagnosis,
- Comply with regulations, in particular standard NF EN 13508-2 governing television inspections (ITV).
In short, the aim is to optimize asset management by combining safety, efficiency and economy.
How do you inspect a sewer system in 2025?
Inspecting an underground network is no simple matter. Depending on pipe diameter, length, condition and presence of water, different methods can be used.
The main inspection technologies :
- Hand-held camera : used in very narrow ducts (DN 50 to 150 mm), it offers rapid inspection but limited range.
- Wired motorized cart : towed on wheels and connected by a cable, it enables live viewing over several dozen meters. However, its use is restrictive (weight, cumbersome cable) and less suitable in the presence of water.
- Autonomous inspection robot : wireless, versatile and often amphibious, it represents the most advanced technology. It offers great freedom of movement, excellent image quality, and can adapt to complex environments.
Today, to combine performance, autonomy and ease of use, the trend is clearly towards new-generation robots, like the Roview2.
Roview2, No. 1 for sewer network inspection
Technology unique on the market
Developed by Multinnovthe Roview2 is currently the only wireless inspection robot designed specifically for confined spaces. This compact, lightweight robot has been designed to meet all field constraints. It combines performance, safety and ergonomics, with a focus on productivity and cost reduction.
Its strengths:
- Zero cables, zero constraints : Unlike conventional ITV carts, the Roview2 operates completely autonomously. It connects via secure wifi to the control tablet, with a range of up to 500 meters, with no loss of signal.
- A high-performance 4K rotating camera : Its 360° (horizontal) and 180° (vertical) rotatable camera offers complete visibility of the environment. The result: sharp images for detailed inspections, and even photogrammetric analysis if required.
- High-intensity LED lighting : the 12,000 lumens built-in allow you to work in total darkness. Even in dirty or buried pipes, visibility remains optimal.
- Adaptable to any terrain : thanks to its amphibious design, the Roview2 is equally at home on dry ground or partially water-filled pipes. It can negotiate obstacles and slopes, and find its way through complex networks.
- Remarkable maneuverability : weighing just 4 kg, the Roview2 can be deployed quickly by a single person, without the need for a tripod or heavy equipment.
- French manufacturing, robust and durable : Like all the brand's products, the Roview2 is Made in France, designed with quality materials and built to last in the field.
Accessories designed for professionals
The Roview2 comes with a full range of accessories available for purchase on the Multinnov Storeto suit every mission:
- Set of small wheels : for exploring very small diameter ducts.
- Floating blades : to optimize navigation in flooded or muddy conditions.
- Range extender : a range extender for long-distance inspections, without losing the signal.
This modularity makes Roview2 a unique tool on the market, capable of evolving according to the needs of the field and the specifics of each worksite.
A response to tomorrow's challenges
In 2025, the expectations of local authorities and manufacturers have changed. They are looking for solutions :
- faster to implement, to limit service interruptions,
- to reduce operator exposure,
- more cost-effective, by reducing labor, emptying and scaffolding costs.
The Roview2 ticks all these boxes. It enables fast, autonomous inspections that comply with current standards, and provides a clear, structured report that is compatible with asset management software.
Its growing adoption by network managers, public works companies and infrastructure operators has made it a benchmark solution in the sector.
A new era in pipe inspection
Inspecting a sewer system no longer has to be synonymous with complexity, bulky cables or lengthy logistical preparations. Thanks to advances in technology, including the Roview2it is now possible to intervene quickly, safely and with unrivalled precision.
Multinnovwith its recognized expertise in confined environments, offers a complete solution designed for professionals in the field. Designed in France and tested in the most demanding environments, the Roview2 is much more than a camera: it's a genuine inspection robot, reliable and robust, ready to accompany sanitation professionals on their daily missions.
