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: 11 days short of water for Randjieslaagte Reservoir, from 189 days with a report; 4 days for Linbro Park Reservoir, from 189; 4 days for Linksfield Reservoir, from 102. 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 Kew's 4 supplies short of water on 18 days
3 March 2025 to 29 September 2026, from 708 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. Linbro Park Reservoir, Linksfield Reservoir and Randjieslaagte Reservoir were supplying fairly or better. Kew gets its water from four reservoirs. This year Randjieslaagte Reservoir was short of water on 11 of the 189 days JW reported it. A typical reservoir or tower in the city had 4 such days. On Randjieslaagte Reservoir, half of its last 10 outages lasted at least 18 hours; the longest since March 2025 lasted 3.9 days. No JW notice we have read names Randjieslaagte Reservoir. None of the 4 passed end dates on its page was met.
Linksfield Reservoir, 29 September 2026: water as normal at 13:20 (JW: “Supplying adequately”), then closed overnight on purpose at 21:05 (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 ↗
Kew draws on four supplies at once: Linbro Park Reservoir, Linksfield Reservoir, Parktown 1 Reservoir and Randjieslaagte Reservoir. JW does not say which street each one reaches.
JW posted 5 notices with an end date that list a suburb or system Kew'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: Linbro Park Reservoir, Linksfield Reservoir, Parktown 1 Reservoir and Randjieslaagte Reservoir.
Under strain
In 2026 so far, Kew had 32 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. Kew 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.
