Water leakage detetion using satellite image

Abstract

Toyota City is replacing 40km of water pipelines annually, and effective and efficient renewal is required. AI based deterioriation prediction and diagnosis tool is introduced for prioritizing replacement. Satellite based SAR image with L-band is also incorporated to detect leakage from reflection properties. The accuracy of water leakage is 27%. Using this technology, required ground inspection length is redued from 2.210km to 257km, and further development and verification is inderway．
