Doornkop

Last Johannesburg Water (JW) report: Tue 29 Sep 2026, 20:15

Both of Doornkop's supplies: short of water on 10 and 18 days this year.

Each from 189 days with a JW report. A typical reservoir or tower in the city had 4.

At JW's last report: Supplying fairly (1) Short of water (1)

JW lists Doornkop under both supplies and does not say which streets each one reaches.

Your street may differ: each report covers a reservoir or tower and the area it feeds, and higher streets lose water first. What JW's words mean

Day by day

In 2026 so far: 18 days short of water for Zondi Reservoir, from 189 days with a report; 10 days for Doornkop Reservoir, from 189. A typical supply in the city, the median one (half had fewer), had 4 days.

Each square is a day, as JW reported it for a supply: a reservoir or tower that JW reports on. The number at the right is the month's days short of water.

In 2026 so far, JW reported at least one of Doornkop's 2 supplies short of water on 27 days

3 March 2025 to 29 September 2026, from 570 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”, as happening or expected (expected most often means higher streets). A warning that it may occur does not count.

In short

The latest JW report on this site is from 29 September 2026; the site last read JW's website on 1 October. That day Zondi Reservoir had weak water or none at 13:20 and was supplying fairly at 20:15. Doornkop Reservoir was supplying fairly. This year Zondi Reservoir was short of water on 18 of the 189 days JW reported it. A typical reservoir or tower in the city had 4 such days. On Zondi Reservoir, half of its last 8 outages were over within 13 hours; the longest since March 2025 lasted 8.9 days. No JW notice we have read names Zondi Reservoir. None of the 9 passed end dates on its page was met.

Latest JW report

Zondi Reservoir, 29 September 2026: weak water or none at 13:20 (JW: “Outlet closed to be opened in the afternoon”), then supplying fairly at 20:15 (JW: “Supplying fairly”).

Where Doornkop gets its water

Doornkop draws on two supplies at once: Doornkop Reservoir and Zondi Reservoir. JW does not say which street each one reaches.

Outages

JW reported 18 outages on Doornkop's supplies since March 2025. The longest lasted 8.9 days. Every outage, with how long it lasted: Doornkop Reservoir and Zondi Reservoir.

JW's end dates

JW posted 9 notices with an end date that list a suburb or system Doornkop's supplies feed. Most name only suburbs, not the reservoir or tower, so the summary at the top uses only a notice that names the supply itself. By the stated time JW's boards showed the water back on none of the 12 end times that have passed. Each end date against what happened: Doornkop Reservoir and Zondi Reservoir.

Under strain

In 2026 so far, Doornkop had 41 days under strain: days when JW reported any of its supplies low or worse, or warned that higher-lying areas may lose water. This is a wider count than days short of water.

The network is linked. Doornkop draws on all its supplies at once, and when one runs low the others carry more. At such times JW's boards sometimes warn of “poor pressure to no water in higher-lying areas”: under strain, higher streets lose water first. JW does not say which streets those are.

What JW's boards cannot tell you

JW's boards report reservoirs and towers, so some things are not in this record:
