Five years to map, meter and zone a water network nobody had documented. By the July 2019 deadline 18.6% of the contract value had been executed; the contractor filed for arbitration and the city wound it up.
what does this mean?
The strongest source is an independent non-academic evaluation: an audit office, a government or EU review, or an NGO. It grades who did the looking — not how well the project went. All four grades →Part of 1001 Smart Cities — 1,167 documented projects · 🏙️ 6 more in Mumbai · 💧 Water guide · 📡 Data & IoT projects
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. The five-year deadline passed in July 2019 with roughly a fifth of the work done; the contractor filed for arbitration and the BMC wound the programme up in March 2021 after paying about 47 crore rupees. Mumbai's supply is still intermittent and its non-revenue water losses remain well above India's 15 percent norm.
📊 Impact
The national auditor found that at the July 2019 deadline only 18.60% of the contract had been executed by monetary value. The city wound the programme up in March 2021 with about 20% of the work done, having paid the contractor about 47 crore rupees; the contractor had filed for arbitration. Mumbai still supplies 3,950 million litres a day against demand of 4,200, and an independent estimate puts non-revenue water at 38% including all unmetered consumption, against a national norm of 15%.
🎓 Lesson
The contract began with the part that had to come first — mapping a network nobody had documented — and that is the part with nothing to show when it stops. Five years produced 18.60% of the contract by value, two pilot wards and an arbitration claim; what the city bought for 47 crore rupees is not a map it can point to. The instruments Mumbai runs today, SCADA and metered-district pilots, are not attributed by any source to this programme. A measurement programme that is abandoned mid-survey leaves the same blind spot it was hired to remove.

Forensic record — source dossiers, gaps, hashes and the exact revision this page renders
This layer records what is known about each source, what is still missing, and the exact snapshot this page is rendering. A missing date, archive or hash stays visible as missing.
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.

The batching script that produced this revision advanced createdAt into the future to satisfy the strictly-increasing order the validator requires per entity. The value never recorded a real event; the corrected value is the moment the revision provably existed in the repository.

Current-state check on what BMC operates after the programme: SCADA plus district-metered-area pilots, automated meter reading, smart-meter pilots. None of it is attributed by the source to this programme, so none is claimed here.

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.
