At Sacyr Water, we have a new system trained with artificial intelligence to detect damage in its collector networks. 
"We believe that AI can achieve very low error rate functionality by training a model that learns from common defects detected by the human eye, such as cracks, fissures, and blockages in the sewerage network.

This Machine Learning model helps us reduce the error rate in detecting these common defects. Additionally, Artificial Intelligence has been implemented to interpret text and generate final reports", explains Miguel Cebrián, head of digital transformation at Sacyr Water.

VIDIA is an asset intelligence platform developed by Sacyr for critical sanitation infrastructure management. 

This system transforms the traditional network inspection process into an automated, data-driven workflow. It doesn't just identify damage; it classifies it according to standardized typologies.

VIDIA utilizes generative artificial intelligence, advanced analytics, and integrated visualization, converting raw data into strategic information for decision-making. It is a tool that unifies everything: people, processes, and technology, providing a 360º view of the service. 

"First, camera footage is captured, which can be done via a drone or a robot within the sewage network. Then, this video is fed into our VIDIA system which, thanks to ML technologies, identifies images, and with Generative AI, analyzes texts and automatically generates reports," states Miguel Cebrián.

Furthermore, VIDIA is integrated with the GIS system. This means all alerts are georeferenced on a city map, allowing for the prioritization of actions in strategic or sensitive areas.

This machine learning model, trained with generative AI, has been jointly developed by Sacyr Water's technical department and the company's IT department. 

VIDIA differs from all similar systems in the water sector because it automates the entire workflow. It not only identifies damage but also contextualizes it: classifying it according to standardized typologies and precisely geolocating it within the collector.

VIDIA is positioned as a key tool to anticipate incidents, reduce operational costs, and ensure service continuity. 

"Digital transformation in sewage network management is no longer an option, but a necessity. This tool transforms a traditionally slow and costly process into an automated, intelligent, and results-oriented workflow", concludes Cebrián.

Understanding the seabed is key before initiating any marine construction project. Bathymetry, or detailed seabed mapping, consistently faces numerous challenges, including the inherent conditions of the sea itself.

These challenges have arisen during the Central Pier Extension, Phase 2, project at the Port of Bilbao. There, we conducted verification tests to enable operations with easily transportable semi-submersible uncrewed vehicles.

"We have innovated by installing a multibeam echosounder and a side-scan sonar on these units. Using acoustic waves, we acquire seabed elevation data," explains Alfredo Pérez, Head of Marine Works at Sacyr Engineering and Infrastructure’s Technical Services Department. Pérez was recently honored with the Natural Innovators 2025 award, a Sacyr internal program for the promotion and advancement of innovation.

"Thanks to this drone, we reduce CO2 emissions and enhance operational capability in the most unfavorable weather conditions," he explains.
"Tests have been conducted both in the open sea and within the port basin. This allows for a more thorough evaluation of the characteristics of this semi-submersible unit and enables a comparison with conventional methods," Alfredo Pérez adds.

Acoustic probes are the only ones that propagate effectively in turbid aquatic environments. This high-frequency echosounder generates a conical beam, providing a data point cloud with far more comprehensive seabed information than traditional single-beam echosounders. This point cloud is then used for data processing, interpolation, and noise reduction, ultimately rendered as contour maps for detailed seabed interpretation.

Bathymetric surveys performed with this method are compared with those obtained by conventional means, and an analysis is conducted to determine if the tolerances between both datasets are within acceptable values.

The echosounder used in Bilbao offers a scan that allows for real-time visualization of the seabed. It provides insights into the terrain's hardness and roughness and performs side scans for object detection. Its measurements can be taken in environments up to four times more challenging than those supported by conventional methods.

"In the future, our goal is to expand the inner data cone to 160 degrees. We also plan to install an antenna on the echosounder to use an airborne bathymetric lidar, which would provide both terrestrial and marine data in a single operation. This way, we will have complete terrain profiles, overlapping both the marine and terrestrial sections," says Alfredo.
