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-e5873b3fd273c797 quantitative
Operation Gcin'amanzi replaced Soweto's flat-rate water billing with re-laid pipes, plumbing repairs and prepaid meters, piloted in Phiri in early 2004 by Johannesburg Water, the City's utility.
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The Court's summary describes the project as piloted in Phiri in early 2004, involving re-laying water pipes and installing prepaid meters; the Mayor's 2008 statement says residents previously paid a flat rate for an unmeasured amount of water deemed to be about 20 kilolitres a month, and lists infrastructure upgrading and plumbing support among the pilot's dimensions. Johannesburg Water is the second respondent in the case.
Caveat
The City's own documents give earlier start dates for the wider programme (2003 in the Mayor's statement); 2004 is the dated start of metering in Phiri.

Sources carrying this claim

  1. Constitutional Court of South Africa — Summary of judgment, Mazibuko and Others v City of Johannesburg and Others, CCT 39/09 (8 Oct 2009)
  2. City of Johannesburg — Judgement of the Phiri case, statement by the Executive Mayor (14 May 2008)
Claim 2 clm-8949c86ca531451d quantitative
Each meter dispensed the free 6 kilolitres a month, then halted supply until credit was bought.
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The full judgment records the High Court's finding that pre-paid meters halt the water supply once the free basic water supply has been exhausted, until the resident purchases credit; the summary states the meters charged for use in excess of the 6 kilolitre per household monthly free basic water allowance.
Caveat
The City also issued a once-a-year emergency token of 4 kilolitres to prepaid households, per the judgment and the Mayor's 2008 statement.

Claim 3 clm-44239ed7374fa49a quantitative
the High Court ruled the meters unlawful on 30 April 2008
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The Mayor's statement opens with the ruling: on 30 April 2008 Judge Tsoka held the pre-payment water system in Phiri unconstitutional and unlawful and ordered 50 litres per person per day; the judgment records that the High Court handed down judgment in April 2008 in favour of the applicants.

Claim 4 clm-b661cad40cd803c5 quantitative
the Supreme Court of Appeal varied that on 25 March 2009
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The Court's case repository files the earlier judgment as 'Earlier judgment 25 March 2009 SCA'; the summary says the Supreme Court of Appeal varied the High Court order, held 42 litres per day sufficient, and found the meters unlawful because the by-laws did not provide for them, giving the City two years to rectify them.

Claim 5 clm-ef9da2ae16f68899 quantitative
on 8 October 2009 the Constitutional Court upheld the meters and the 6 kilolitre policy
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The summary is dated 8 October 2009 and states that the Court held, contrary to the lower courts, that national legislation and the City's by-laws authorise prepaid meters, that their installation was neither unfair nor discriminatory, and that it was not unreasonable for the City not to have supplied more than 6 kilolitres.

Claim 6 clm-7a64e7dd7f6035bd quantitative
The City claimed 80,000 meters on 6 May 2008 and 'over 95 300' eight days later.
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The 6 May statement says 80 000 meters have been installed since the start of the operation; the 14 May statement says that by April 2008 over 95 300 meters were installed out of 170 000 targeted stands in Soweto. The two counts are the City's own and eight days apart.
Caveat
Neither statement explains the difference; the atlas reports both rather than choosing one.

the 2023–25 switch of open-mode meters to prepaid found meters bypassed or vandalised
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Johannesburg Water announced on 25 July 2023 that it was switching from open mode to prepaid smart meters from 31 July in Cosmo City, Orlando East and West, Diepkloof and Orange Farm, pairing open meters with Customer Interface Units; the City's 2024/25 annual report says open mode meters were switched to prepaid and some newly installed meters were bypassed or vandalised shortly after installation.

Claim 9 clm-8a65b7713650f8dc quantitative
monthly consumption per property in Soweto fell from 66 kilolitres before the intervention to an average of 11 kilolitres where meters were installed, and unaccounted-for water fell from 40% to 32% in 2007
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The City's statement says consumption per property was 66 kilolitres before the intervention and dropped to an average of 11 kilolitres in areas where meters were installed, and that prepaid meters reduced unaccounted-for water loss from 40% to 32% in 2007.
Caveat
Operator self-report, not an independent measurement; the City's statement eight days later gives 12 kilolitres, and the 85 per cent reduction it quotes is its own arithmetic.

in the year to 30 June 2015 the City collected R9.1 million of a possible R100 million from the 138,723 prepaid meters installed in Soweto since 2004, and Johannesburg Water admitted most had been illegally bypassed

mapped · no interpretation or interpolation added by this file
What the mapping says
TimesLIVE, citing a report to a council committee, states that in the year ending June 30 the city collected only R9.1-million out of a possible R100-million from the 138723 prepaid meters installed in Soweto since 2004, and that Johannesburg Water had admitted most of the meters were illegally bypassed.
Caveat
The 'possible R100 million' is the council report's own estimate of billable revenue, as relayed by the newspaper.

Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The City's 2024/25 annual report says some newly installed meters were either bypassed or vandalised by customers shortly after being installed, that by-law enforcement is being intensified, and that Johannesburg Water is working with JMPD to perform level 3 disconnections; it counts 40 537 STS meters installed in Soweto, Orange Farm and Alexandra.
Caveat
Johannesburg Water's own reporting; the report does not say how many of the 40 537 meters were bypassed.

What the mapping says
The report on the 2017/18 budget says residents will no longer receive their first 6 000 litres of water free, and that the Executive Mayor had announced that from 1 July only indigent households would receive free water, between 10 and 15 kilolitres depending on their poverty-index score.

Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The approved 2026/27 water tariff schedule lists the 0-6 kilolitre band as free for both prepayment and conventional domestic meters, and a residential indigent table with monthly free-water caps of 10 kl, 12 kl and 15 kl for bands 2 to 4 of the City's poverty index.
Caveat
The schedule is a tariff table, not a narrative; the date on which the free 6 kilolitres returned for non-indigent households is not in this entry's sources. Deemed-consumption areas carry a separate line of 5 kilolitres free.
