Kaalfontein
Last Johannesburg Water (JW) report: Tue 29 Sep 2026, 20:55
At 20:55 JW wrote: “On bypass. Supplying fairly. Poor pressure may occur.”
On 3 more days JW printed a warning. President Park Reservoir: 35 of 189. A typical reservoir or tower in the city had 4.
JW lists Kaalfontein 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: 87 days short of water for President Park Tower, from 189 days with a report; 35 days for President Park 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.

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.
Is anyone fixing it?
No JW notice we have read names President Park Tower.
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 President Park Reservoir had weak water or none at 13:00 and closed overnight on purpose at 20:55. President Park Tower had water, weak in some places. This year President Park Tower was short of water on 87 of the 189 days JW reported it. A typical reservoir or tower in the city had 4 such days. On President Park Tower, half of its last 10 outages were over within 21 hours; the longest since March 2025 lasted 40.6 days. No JW notice we have read names President Park Tower. None of the 2 passed end dates on its page was met.
Latest JW report
President Park Reservoir, 29 September 2026: weak water or none at 13:00, the worst status in this report (JW: “Low and supplying, poor pressure to no water is expected in certain parts”), then closed overnight on purpose at 20:55 (JW: “Outlet closed overnight to build capacity”).
JW put it on its website 1 October 2026 at 13:40. JW's page for this board ↗ · JW's image of the board ↗
President Park Tower, 29 September 2026: water, weak in some places at 20:55, on bypass, the worst status in this report (JW: “On bypass. Supplying fairly. Poor pressure may occur”).

“On bypass” is JW's term. When JW repaired Hursthill 2 Reservoir from December 2025, it put the reservoir on bypass so that teams could work safely inside, and customers still received water; the news reports said this could bring periods of low pressure or no water (EWN ↗, The Citizen ↗). A reservoir or tower on bypass does not count as back when this page checks JW's end dates.

Where Kaalfontein gets its water
Kaalfontein draws on two supplies at once: President Park Reservoir and President Park Tower. JW does not say which street each one reaches.

Outages
JW reported 42 outages on Kaalfontein's supplies since March 2025. The longest lasted 40.6 days. Every outage, with how long it lasted: President Park Reservoir and President Park Tower.
JW's end dates
JW posted 7 notices with an end date that list a suburb or system Kaalfontein'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 6 end times that have passed. Each end date against what happened: President Park Reservoir and President Park Tower.
Up the supply chain
Kaalfontein's supplies are in JW's Midrand system.

Under strain
In 2026 so far, Kaalfontein had 111 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. Kaalfontein 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:
- 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.
