Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-36b7787fe144b77f quantitative
In 2014 the BMC hired Suez Environnement India under a 275 crore rupee contract to GIS-map Mumbai's poorly documented water network, zone it into district metered areas, meter connections, detect leaks and move two wards to continuous pressurised supply
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The audit report as reported names the 2014 award to Suez Environment India at about 276 crore rupees and the two pilot wards; the 2021 report lists the ten contracted services including GIS mapping and leakage detection.
Caveat
The reported contract value is about 276 crore rupees; the entry's 275 is a rounding of the same award.

Awaiting operator and domain-expert review; publication of this revision implies neither.

Erratum on this revision's envelope. The snapshot, its hash and its permanent link are untouched.

  • createdAt previously read 2026-08-26T23:21:00Z. The batching script that produced this revision advanced createdAt into the future to satisfy the strictly-increasing order the validator requires per entity.

Known limits of this passport
  • Publisher names and source languages have not yet been classified; domains are recorded without guessing.
  • Existing source notes are descriptive locators, not page- or paragraph-exact citations.
  • A missing archive, publication date or content hash is shown as null rather than inferred.
  • The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
