# WaterAtlas

> The AI-native home of the global water industry: a verified, provenance-backed
> directory of water companies (Asia-first), a daily intelligence engine, and an
> open, citation-anchored Water Wiki — welded together by a Wikidata-compatible
> knowledge graph. Structured data is CC0; prose is CC BY-SA 4.0; the WICS
> taxonomy is CC BY 4.0.

The directory contains 33 published company profiles and 0 product models
across 14 countries (58% Asia-Pacific), plus 150 wiki articles and
16 intelligence briefs. Directory records carry field-level provenance.
