From April to September 2026 (six months), JW reported Illovo Reservoir short of water on 3 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: 5 days short of water for Illovo Reservoir, from 189 days with a report. The median supply in the city: 4 days.

On Illovo Reservoir, half of its last 10 outages lasted at least 28 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 10 outages on Illovo 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 (2 of 10).

Still out at JW's last report (29 September 2026): Illovo Reservoir, at least 3 hours so far.

JW's notices gave 8 end times for Illovo Reservoir. By the stated time, JW's boards showed the water back on none of the 8 that have passed

The water came back after the stated time 8 times; half of those times it was back within 20 hours 22 minutes of it. Each row is one end time a JW notice stated for one supply, in date order (hollow dot), against the first board on which JW reported the supply supplying fairly or better and off bypass (filled dot). This asks more than the end of an outage, which comes at JW's first report better than “poor pressure to no water” or “critically low”. An arrow: no such board yet. From 11 notices.

In words

2026 so far: JW reported it at “poor pressure to no water” or “critically low” on 5 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 13 days. JW published a report for it on 94 of the 304 days in the record; the other 210 days have no report, and we do not count them as normal. The median supply in the city had 1 such day.

The last 10 outages JW reported on this supply lasted a median of at least 28 hours; the longest at least 3.6 days. 2 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 Illovo Reservoir on 3 March 2025 and last on 29 September 2026: 481 statuses on 481 boards, over 283 days. 46 of those statuses announced a scheduled overnight closure, which we count apart, never as an outage.

Days JW reported Illovo 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 Illovo 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.
