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: 3 days short of water for Northcliff Tower, from 58 days with a report; 1 day for Northcliff Reservoir, from 54. 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 Waterval Estate's 2 supplies short of water on 3 days

3 March 2025 to 29 September 2026, from 175 days with a JW report.

Northcliff Reservoir

In 2026 so far: 1 day short of water, from 54 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. Northcliff Reservoir and Northcliff Tower had water as normal. JW reported Northcliff Reservoir and Northcliff Tower short of water on 1 and 3 days this year. A typical reservoir or tower in the city had 4 such days. On Northcliff Tower, half of its last 3 outages lasted at least 25 hours; the longest since March 2025 lasted at least 2.5 days.

Latest JW report

Where Waterval Estate gets its water

Waterval Estate draws on two supplies at once: Northcliff Reservoir and Northcliff Tower. JW does not say which street each one reaches.

Outages

JW reported 4 outages on Waterval Estate's supplies since March 2025. The longest lasted at least 2.5 days. Every outage, with how long it lasted: Northcliff Reservoir and Northcliff Tower.

JW's end dates

JW posted 10 notices with an end date that list a suburb or system Waterval Estate'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 11 end times that have passed. Each end date against what happened: Northcliff Reservoir and Northcliff Tower.

Under strain

In 2026 so far, Waterval Estate had 4 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. Waterval Estate 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:
