Water cut for two days or more
Official: Stats SA, General Household Survey 2025 · Data as of General Household Survey 2025
Stats SA: “a smaller percentage of households in metropolitan areas reported water interruptions (30,0% compared with 37,6%). Water interruptions were most common in eThekwini (43,9%), which is almost six time more common than in the City of Cape Town (7,8%).”
Cut 2+ days: households that answered yes to a water cut of 48 hours or more at a time, in thousands as Stats SA prints them (Table 2.8: Water and sanitation variables by metro); all households from Table 3.7. A sample survey. Sources: GHS 2025: selected development indicators, metros (P0318.3); the quotation is from the main GHS 2025 release (P0318), section 9.3.

Water lost before it reaches a meter
Official: audited annual financial statements · Data as of 2024-25 financial year (audited statements) · Next update expected Jan 2027 (2025-26 annual reports) · Last updated
Water a metro buys or purifies but never bills: leaks, burst pipes, illegal connections and faulty meters. Treasury’s norm is 15% to 30%.
What these words mean
Distribution losses
Water or electricity a metro buys or produces but never bills: leaks, theft, illegal connections and faulty meters.
Non-revenue water
All water that earns no money, including water given free to poor households. Close to, but not the same as, water lost.
Treasury norm
A target National Treasury sets for every municipality in MFMA Circular 71, so metros can be compared on the same scale.

Ml a day
Megalitres a day. One megalitre is a million litres, about half an Olympic swimming pool.
Water-use licence
The national Department of Water and Sanitation’s permission for Rand Water to take water from the Vaal system: a permanent amount, and a higher temporary one. Rand Water shows each metro’s share as a level in Ml a day.
3 641 Ml a day
The three metros’ average use of Rand Water’s water in the week of 21 Sep 2026: 20% above the 3 045 Ml a day Rand Water sets for them under its permanent licence, and 1% more than a year earlier (3 620 Ml a day).

Average megalitres a day each week, read from Rand Water’s bulk meters. This is water the metro buys, not water residents use: some is lost in the metro’s own pipes (see “Water lost before it reaches a meter”). Rand Water states its licences as 1 600 million m³ a year (permanent) and 1 803 million m³ a year (temporary), and shows each metro’s level in Ml a day.

Each metro’s main water supply system
Official: DWS weekly State of Reservoirs, copied 10 Oct 2026 · Data as of see the copy date · Updates: DWS publishes weekly; we copy by hand
DWS: these summaries cover only the dams in its State of Reservoirs report. Several metros share a system: Johannesburg, Tshwane and Ekurhuleni all draw mainly on the Integrated Vaal River System. Each metro’s main system is confirmed from its own documents. Cape Town and Nelson Mandela Bay publish their own dam levels; their Water pages show them first. The DWS site refuses automated requests, so these figures are copied by hand from its summary pages each week (copied 10 Oct 2026; the report’s own date was not copied).

Planned and unplanned water interruptions each metro announced since 1 Jan 2025, matched to wards by the places they name. Metros publish very differently, so the counts say more about how each metro publishes than about how often the water is off.
