On Randjesfontein Reservoir, its one outage lasted 41 hours
This is not a forecast. It is how long past outages lasted. Each dot is one past outage, placed by its length: the one outage on Randjesfontein Reservoir. A hollow dot with an arrow had no reported end: JW's reports stopped before it ended, or it was still going at JW's last report. Either way it lasted at least that long (0 of 1).

In words
2026 so far: JW reported it at “poor pressure to no water” or “critically low” on 2 days. JW published a report for it on 9 of the 272 days in the record; the other 263 days have no report, and we do not count them as normal. The median supply in the city had 4 such days.
2025: JW reported it at “poor pressure to no water” or “critically low” on 0 days. JW published a report for it on 45 of the 304 days in the record; the other 259 days have no report, and we do not count them as normal. The median supply in the city had 1 such day.
The one outage JW reported on this supply lasted 41 hours. This is a record of the past, not a forecast.
JW's boards first named Randjesfontein Reservoir on 3 March 2025 and last on 3 June 2026: 57 statuses on 57 boards, over 54 days. 1 of those statuses announced a scheduled overnight closure, which we count apart, never as an outage.
Month by month
Days JW reported Randjesfontein Reservoir at “poor pressure to no water” or “critically low”, out of the days it reported it at all. A month with few reported days says little.

Past outages
Each row is one outage: a stretch of time JW reported Randjesfontein Reservoir at “poor pressure to no water” or “critically low”, newest first. An outage has no reported end when JW's reports stopped before it ended, or when it was still going at JW's last report; its length is then a minimum.
| Start | End | Length |
|---|---|---|
| 1 Feb 2026, 20:20 | 3 Feb 2026, 13:30 | 41 hours |
What JW's boards cannot tell you
- Whether water reaches your street or your tap.
- Which streets lose water first: JW warns of higher-lying areas but does not name the streets.
- Why a supply ran low, unless a JW notice gives a reason.
- Pipe bursts, tankers and valve work, which are not on the boards.
