ASTERRA

ASTERRA — 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 r…

ASTERRA offers (Alternative, Geospatial) — Concrete scale anchor: over 23,000 km of pipeline serving more than 11.5 million people, screened repeatedly across quarterly and annual service rounds for five years (August 2019 to August 2024), with cumulative leaks identified, POI counts and crew field days reported by round. SAR revisit of the full Greater Buenos Aires urban area each round implies tens of thousands of square kilometres imaged and very large POI and verification counts by 2024, with exact figures reported per round in the case study tables.

Training SAR-based subsurface moisture and leak-detection models on verified urban outcomes, which is the single scarcest training set in this domain; false-positive suppression for satellite leak detection; detection-threshold and resolution studies in dense urban environments where the vendor claims specific advantage; non-revenue-water reduction modelling against a documented baseline of 37.4% loss and a 55,000 cubic metre per day savings target; utility asset-investment prioritisation across a 23,000 km network; and development-finance and regulatory benchmarking, given the Inter-American Development Bank mediated the original engagement
