Why choose the Elios 3 drone for sewer inspections?
The Elios 3 brings cutting-edge robotics to sewer management, elevating safety and efficiency without diminishing the quality of results.
Flying inside pipes as small as 60 cm in diameter, this solution empowers detailed reconnaissance with a 4K camera and centimeter-accurate LiDAR payload. These combined capabilities provide rapid insights into previously inaccessible areas, making it instrumental to streamlining complex sewer inspection and mapping projects.
Data from the Elios 3 can be viewed with the custom software solution Inspector, providing side-by-side comparisons of visual inspections with a 3D point cloud, making it easy to identify and localize points of interest or defects. For additional analysis of the point cloud, the Elios 3’s Surveying Payload offers custom presets in FARO Connect. The Elios 3 data can also be imported to WinCan Web for visual inspections and reporting. The insights gathered by this solution are enhancing situational awareness for planning, maintenance, and emergency response in sewer management worldwide.

The benefits of integrating drones for pipelines and sewage systems inspections
Safely inspect inaccessible places
Access sections of sewer systems through manholes and other small entry points. Quickly collect data from a safe distance, regardless of obstructions, access issues, or confined space entry procedures.
Pinpoint & document
any defects
In line with official reporting standards, you can localize the exact position of defects found during an inspection within the 3D model of your asset, for improved assessment and maintenance work processes.
Collect objective & precise data
Provide a crystal clear view of the pipe and assets’ conditions with 4K video footage and centimeter-accurate scans. The Elios 3 provides greater control over data capture compared to other RVI tools such as CCTV.

Exploring applications for our drones in the water & wastewater management industry
-
Culvert inspection (cockpit view)
Read moreUse a drone to precisely localize collapses, problems with joints or seams, and buildup of debris that could obstruct the flow of water.
-
Culvert inspection (software output)
Read moreOnce the mission is completed, download the drone data into Inspector, the Elios 3’s companion software. Review each flight frame by frame and precisely localize all points of interest within a 3D model of the asset.
-
Georeferencing of underground networks
Read morePrecisely geolocate detected networks in space and generate centimeter-accurate maps of inaccessible sewer systems.
-
Wastewater settling basin inspection & software output
Read moreUse the Elios 3 to rapidly assess tank condition, checking for deterioration, leaks, corrosion, etc. Conduct detailed inspections of ancillary equipment such as pumps, flanges, and joints inside the tank. Back in the office, analyze mission-recorded points of interest precisely using Inspector.
-
Sewage system inspection
Read moreFly the drone inside sewer systems with diameters as small as 75 cm. Scan galleries at a pace of 900 meters per day of inspection.
-
Canal inspection and photogrammetry
Read moreUse a drone to spot a collapse and make a photogrammetric model to localize and measure it in the pipe.
