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-09446e1ab3e2a381 descriptive
ASKİ runs Ankara's drinking-water network from a single SCADA control centre, staffed around the clock, with reservoirs, pump stations and network measurement points reporting in so that leaks and failures can be found without waiting for a burst to surface
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The operator's then general manager stated that 106 water reservoirs, 59 pump stations and 93 measurement points across Ankara were connected to the SCADA system, describing a 24-hour main control centre with three operators per shift.
Caveat
That page is dated 10 March 2011 and its figures are fifteen years old, although search engines surface them as if current. It is used here only to establish that centralised SCADA control predates 2011 — no start year for the original system could be established from any source, so none is claimed.

Claim 2 clm-a1c6e22bc81abaef quantitative
the utility's own 2025-2029 strategic plan opens the planning period at a 42% loss rate and sets 25% as the target for 2029
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The plan's core performance indicator table gives a plan-period opening value of 42 and an end-of-plan target of 25 for the loss-and-leakage rate, with strategic goal 1.5 being to reduce it.
Caveat
No claim-specific caveat recorded

Claim 3 clm-8b84fa74ee549fdc quantitative
The same plan lists "high loss rate" among ASKİ's self-declared weaknesses and records SCADA renewal as 0% complete in 2025, due to reach 100% only in 2029
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The plan's own SWOT lists the high loss-and-leakage rate as a weakness and the forthcoming SCADA renewal as a factor; indicator PG.1.1.1, the SCADA system renewal rate, carries a 2025 baseline of 0 and a 2029 target of 100, owned by the IT directorate.

Claim 4 clm-08f1d83e475c83a1 quantitative
Turkish press citing Court of Accounts (Sayıştay) audits reports roughly 38% for 2019-2020, 36.35% for 2021 and above 30% for 2023-2024
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The press account of the audit gives roughly 38 per cent for 2019-2020, 36.35 per cent for 2021 and above 30 per cent for 2023-2024, against a ministry regulatory ceiling of 30 per cent for 2023, and frames the losses as a risk of loss to the public purse.
Caveat
The underlying audit report itself was not retrieved: these year-by-year percentages rest on this press account, while the 42 and 25 per cent figures rest on the utility's own plan.

What the mapping says
The Istanbul comparison point already in the atlas records non-revenue water falling from 22.3 per cent in 2019 to 18.6 per cent in 2024 under the same architecture.

Claim 6 clm-cb2da8476911e575 quantitative
the gap between 18.6% and 42% is not explained by which of them owns the technology. A control room tells you where the water is going; it does not replace the pipe
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The peer-reviewed study of a district metering area in Gölbaşı without SCADA found that minimum night flow rose again a year after remediation — creating a metering zone without continuous monitoring does not hold the gain. Against that mechanism, the utility's own plan still opens at 42 per cent and schedules its SCADA renewal to finish only in 2029.
Caveat
The study supports the mechanism, not the citywide percentages, and the comparison between the two cities is the entry's own.

DATED 10 MARCH 2011 — the figures here are fifteen years old and are not current; search engines surface them as if they were. ASKİ's then general manager: "Ankara genelindeki 106 su deposu, 59 pompa istasyonu, 93 ölçüm noktası SCADA sistemine bağlıdır." Describes a 24-hour main control centre with three operators per shift. Used here only to establish that centralised SCADA control predates 2011.

"Su Dağıtım Şebekelerindeki Fiziki Kayıpların Önlenmesinde SCADA'nın Önemi: ASKİ Örneği". Studies a district metering area in Gölbaşı without SCADA: minimum night flow rose again a year after remediation, i.e. creating a metering zone without continuous monitoring does not hold the gain. Supports the mechanism, not the citywide percentages.

Secondary reporting of the Court of Accounts audit: ~38% for 2019-2020, 36.35% for 2021, above 30% for 2023-2024, against a Ministry of Agriculture and Forestry regulatory ceiling of 30% for 2023. Frames losses as "kamu zarar riski". The underlying Sayıştay report itself was NOT retrieved — the year-by-year percentages here rest on this press account, while the 42%/25% figures rest on ASKİ's own plan.

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.
