Municipal pipe-leak risk corpus

Name: Municipal pipe-leak risk corpus: per-pipe-segment leakage risk scores for Japanese water networks, fusing satellite-measured external drivers (surface temperature, land motion/subsidence) with utility-owned internal pipe attributes (age, thickness, pressure history) and actual survey/repair outcomes. Coverage now spans 100+ municipal water operators, plus adjacent sewer-inspection prioritisation and land-value/agriculture layers on the same COMPASS GIS platform

Type: not stated
Format: Multimodal — GIS vector layers of pipe networks with per-segment risk attributes, satellite raster time series (optical and SAR-derived land motion), and tabular survey/repair outcome records; delivered through the Tenchijin COMPASS online GIS platform
Volume: Target market context is concrete: Japan has over 189,000 km of water pipe older than 40 years and roughly 20,000 new leaks per year. Risk scoring is therefore applied to a pipe network measured in tens of thousands of kilometres across 100+ municipalities, re-scored on each satellite revisit, so the geocoded per-segment risk history plausibly runs to hundreds of millions of segment-epoch records
Users: 100+ municipal water operator contracts (stated milestone); end users are municipal water-utility staff — plausibly low thousands of seats. KnoWaterleak Cloud early access is scoped to 100 utilities from 1 September 2026
History: 5 years
Update frequency: not stated
Growth: Active and accelerating — September 2026 press releases (Nagaki water-exhibition exhibition, 16-municipality Oita deployment, water-DX strategy seminar, ESA/JAXA/CONSEO panel), 100-contract milestone, and KnoWaterleak Cloud browser successor shipping with early access 1 September 2026 and general FY2027 release
Launched: ~2019 (early director joined December 2019; JAXA-backed founding cohort; KnoWaterleak field-validated in FY2022 Cabinet Office projects, so the product existed before that)
