Riverglen

Last Johannesburg Water (JW) report: Tue 29 Sep 2026, 21:05

Both of Riverglen's supplies: short of water on 5 and 9 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) Water as normal (1)

JW lists Riverglen 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: 9 days short of water for Diepsloot Reservoir, from 189 days with a report; 5 days for Bryanston 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 Riverglen's 2 supplies short of water on 14 days

3 March 2025 to 29 September 2026, from 561 days with a JW report.

Bryanston Reservoir

In 2026 so far: 5 days short of water, from 189 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. Bryanston Reservoir and Diepsloot Reservoir were supplying fairly or better. This year Diepsloot Reservoir was short of water on 9 of the 189 days JW reported it. A typical reservoir or tower in the city had 4 such days. On Diepsloot Reservoir, half of its last 7 outages lasted at least 23 hours; the longest since March 2025 lasted 3.3 days. No JW notice we have read names Diepsloot Reservoir.

Latest JW report

Bryanston Reservoir, 29 September 2026: supplying fairly at 13:20 (JW: “Supplying fairly”), then water as normal at 21:05 (JW: “Supplying adequately”).

Where Riverglen gets its water

Riverglen draws on two supplies at once: Bryanston Reservoir and Diepsloot Reservoir. JW does not say which street each one reaches.

Outages

JW reported 15 outages on Riverglen's supplies since March 2025. The longest lasted 3.3 days. Every outage, with how long it lasted: Bryanston Reservoir and Diepsloot Reservoir.

JW's end dates

JW posted 12 notices with an end date that list a suburb or system Riverglen'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 9 end times that have passed. Each end date against what happened: Bryanston Reservoir and Diepsloot Reservoir.

Under strain

In 2026 so far, Riverglen had 18 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. Riverglen 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:
