Access Using outdated 2D maps as their guide, the Elios 3 was deployed during low tide to enter underground canals that hadn’t been accessed since construction. This allowed for a safe and effective drone river inspection. Data Quality The team captured high-quality visual data, including photos, videos, and a LiDAR scan that exceeded expectations. The client was impressed with the detailed results, which were gathered without extra effort or time. Safety Human entry into this environment is extremely dangerous due to fluctuating water levels and strong currents. The Elios 3 provided the only viable solution, ensuring the safety of the team. Speed All data was collected in just one day, compared to the several days typically required for traditional methods. This made the process much more efficient and cost-effective.

Key Benefits at a Glance
Planning a Drone River Inspection for an Underground Canal
Sater, a French company based near Lille, specializes in water and wastewater management. As part of the Veolia group, they have over 30 years of experience and operate across France. Sater frequently deals with complex environments where traditional methods fall short. To improve their capabilities, they invested in the Elios 3, a powerful drone designed for sewer and water network inspections.
Recently, Sater used the Elios 3 to inspect underground canals in Rouen ahead of a major construction project. With the drone’s proven track record, they were confident in its ability to gather the necessary data.
Inspecting Canals with Drones
At the Marché d'Intérêt National (MIN) in Rouen, a river runs beneath buildings and streets before flowing into the Seine. Before any surface-level construction could begin, the condition of the underground canal had to be assessed.
This type of inspection comes with significant risks, especially with tidal influences from the Seine. Sater planned the mission carefully, choosing the best time to minimize water levels and ensure a successful flight.
The canal consists of two parallel pipes, each 3 meters in diameter, stretching 540 meters underground. Inspecting both was crucial for the project’s success.
Conducting the Drone River Inspection Underground
Sater had no up-to-date maps, so they relied on historical records. They conducted the inspection at low tide, flying the Elios 3 through the narrow openings of the pipes. Despite the tight spaces and limited visibility, the drone successfully navigated the area using its visual camera and LiDAR technology.
The mission not only provided clear visual data but also captured detailed LiDAR scans, offering a precise 3D model of the canal. This information proved invaluable for future planning and maintenance.
Impressing the Municipality with Drone Results
The primary goal was to provide the client with video footage of the interior of the pipes. However, the additional LiDAR data amazed the client, who was pleased with the level of detail and accuracy.
The 3D model gave a complete view of the structure without exposing personnel to risk. Sater’s use of the Elios 3 not only met the project’s requirements but also set a new standard for future inspections. It showed how drones can push the boundaries of what’s possible in urban water management.
