Ridgeway
Last Johannesburg Water (JW) report: Tue 29 Sep 2026, 20:30
Crown Gardens Reservoir and Crown Gardens Tower: short of water on 12 and 13 days this year.
Each from 185 days with a JW report. A typical reservoir or tower in the city had 4.
At JW's last report: Shut for the night (1) Supplying fairly (1)
JW has not reported Alan Manor Reservoir this year.
JW lists Ridgeway under all three 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

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. Crown Gardens Tower was supplying fairly. Crown Gardens Reservoir closed overnight on purpose. JW's last report of Alan Manor Reservoir is from 5 June 2025. Ridgeway gets its water from two reservoirs and a tower. This year Crown Gardens Tower was short of water on 13 of the 185 days JW reported it. A typical reservoir or tower in the city had 4 such days. On Crown Gardens Tower, half of its last 8 outages were over within 30 hours; the longest since March 2025 lasted 3.8 days. No JW notice we have read names Crown Gardens Tower.

Where Ridgeway gets its water
Ridgeway draws on three supplies at once: Alan Manor Reservoir, Crown Gardens Reservoir and Crown Gardens Tower. JW does not say which street each one reaches.

|---|---|---|

| Crown Gardens Reservoir | Central | Listed on JW's pages, as Ridgeway Ext.4, Ridgeway Ext.5, Ridgeway Ext.8. Source 1 ↗ Source 2 ↗ |

Outages
JW reported 15 outages on Ridgeway's supplies since March 2025. The longest lasted 3.8 days. Every outage, with how long it lasted: Alan Manor Reservoir, Crown Gardens Reservoir and Crown Gardens Tower.
JW's end dates
JW posted 18 notices with an end date that list a suburb or system Ridgeway'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 14 end times that have passed. Each end date against what happened: Alan Manor Reservoir, Crown Gardens Reservoir and Crown Gardens Tower.
Under strain
In 2026 so far, Ridgeway had 42 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. Ridgeway 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.
