ACCIONA has incorporated cutting-edge technologies—such as drones and robots—for the inspection and review of Bilbao’s sewerage networks. The company has already completed an initial pilot using this new technology across 11 of the 61 kilometers of network suitable for its application, defined as sections with a diameter greater than 80 centimeters.

Drones for hard-to-reach areas

The drones used are equipped with high-resolution cameras capable of detecting blockages, leaks, and structural deterioration in hard-to-access zones, enabling faster, more accurate diagnostics.

AI-enabled quadruped robots

The robotic “dogs”—which ACCIONA also uses to inspect tunnels and confined spaces—are designed to navigate tight areas and feature 360º cameras and artificial intelligence systems that help identify cracks, corrosion, or debris build-up inside pipes.

Operational and safety advantages

These tools enhance occupational safety by reducing the need for workers to physically enter potentially hazardous spaces. They also improve operational efficiency, as the technology can collect real-time data to anticipate potential failures.

Likewise, drones and robots allow resources to be optimized by preventing major breakdowns and reducing the environmental impact associated with emergency interventions.

The use of these technologies will enable more efficient and sustainable maintenance of Bilbao’s sewerage network.
