Water utilities lose 20–40% of treated water to buried leaks — real money, lost out of sight. The satellite leak services we're aware of rely on tasking SAR, which can't economically cover a whole national network at the frequency proactive management needs. ETD's 2 m moisture indices (NDMI, MSAVI + a proprietary fusion) resolve the small, persistent soil-moisture anomalies a 2–8 m leak produces — invisible at native 10–20 m — every 2–3 days, nationwide, priced as a subscription rather than per scene, and delivered as geolocated alerts with confidence and persistence for the utility's GIS. Patent-pending.
