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. Chiawelo Reservoir and Power Park Reservoir had water as normal. JW reported Chiawelo Reservoir and Power Park Reservoir short of water on 0 and 4 days this year. A typical reservoir or tower in the city had 4 such days. On Power Park Reservoir, half of its last 4 outages were over within 19 hours; the longest since March 2025 lasted 34 hours.
JW reported 4 outages on Klipriviersoog's supplies since March 2025. The longest lasted 34 hours. Every outage, with how long it lasted: Chiawelo Reservoir and Power Park Reservoir.
JW's end dates
JW posted 6 notices with an end date that list a suburb or system Klipriviersoog'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: Chiawelo Reservoir and Power Park Reservoir.
Under strain
In 2026 so far, Klipriviersoog had 12 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. Klipriviersoog 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.
