Automatic Detection of Defects in Sewer Networks

What is SEWDEF?

SEWDEF is an automatic detection system for defects in sewer networks based on artificial intelligence and computer vision that analyzes the videos of the sewer network in search of defects.

In use since 2017, SEWDEF is the first industrial solution worldwide, which solves the need for innovation, raised by EurEau (European Association of Supply and Sanitation Management Entities) and AEAS (Spanish Association of Water Supply and Sanitation), of apply artificial intelligence to asset management.

SEWDEF allows sewerage network management companies to obtain objective data for the planning and prioritization of investments, preventive, cleaning and maintenance work to avoid collapses, breakages or floods in times of rain.

The system detects 16 types of defects classified into 4 subgroups – structural defects, capacity defects, structural elements and others – also providing an assessment of the condition of the inspected section.

In this way, infrastructure managers will be able to obtain objective information on the state of the sewerage network and its temporal evolution in order to know its rate of degradation in order to plan and prioritize preventive maintenance actions.
