The most operationally validated satellite-leak corpus in this cohort: SAR-derived subsurface moisture detections — wet soil carrying the dielectric signature of drinking water — overlaid on the utility's GIS pipe network to produce Points of Interest, which field crews then pinpoint and repair, closing a full detect-to-repaired loop. Run continuously since 2019 at AySA, the state-owned Argentine water and sanitation utility serving over 11.5 million people across Buenos Aires and 25 surrounding districts through over 23,000 km of pipelines, delivering quarterly and annual service rounds with cumulative leak counts, POI counts and crew field days recorded per round
