Witpoortjie Reservoir over time

In 2026 so far, JW reported Witpoortjie Reservoir short of water on 2 days

What JW reported each day, 3 March 2025 to 29 September 2026, one row a month; the number at the right is the month's days short of water. Based on 242 days with a JW report. A day counts as short of water when JW's worst report for it that day was “poor pressure to no water” or “critically low”. Gaps: Witpoortjie Reservoir: no report from 3 March 2025 to 20 May 2025; Witpoortjie Reservoir: no report from 25 July 2025 to 31 January 2026.

From April to September 2026 (six months), JW reported Witpoortjie Reservoir short of water on 2 of 161 reported days

Days per month short of water, stacked: critically low at the base. The tick is the median supply in the city that month. The strip under each bar is the share of days with a JW report; a month with none says gap. 3 March 2025 to 29 September 2026.

In 2026 so far: 2 days short of water for Witpoortjie Reservoir, from 189 days with a report. The median supply in the city: 4 days.

On Witpoortjie Reservoir, half of its last 3 outages lasted at least 25 hours

This is not a forecast. It is how long past outages lasted. Each dot is one past outage, placed by its length: the last 3 outages on Witpoortjie 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 (1 of 3).

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 189 of the 272 days in the record; the other 83 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 1 day. JW published a report for it on 53 of the 304 days in the record; the other 251 days have no report, and we do not count them as normal. The median supply in the city had 1 such day.

The last 3 outages JW reported on this supply lasted a median of at least 25 hours; the longest at least 36 hours. 1 of them had no reported end (still open, or JW's reports stopped), so they count at the length so far. This is a record of the past, not a forecast.

JW's boards first named Witpoortjie Reservoir on 21 May 2025 and last on 29 September 2026: 433 statuses on 433 boards, over 242 days. 30 of those statuses announced a scheduled overnight closure, which we count apart, never as an outage.

Past outages

Each row is one outage: a stretch of time JW reported Witpoortjie 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.
