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

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. Waterval Tower was critically low. This year Waterval Tower was short of water on 13 of the 180 days JW reported it. A typical reservoir or tower in the city had 4 such days. No JW notice we have read names Waterval Tower.
On JW's list of towers, June 2024, as Bergbron, Bergbron Ext.1, Bergbron Ext.2, Bergbron Ext.6, Bergbron Ext.8, Bergbron Ext.9. Source 1 ↗
Outages
JW reported 12 outages on Bergbron's supply since March 2025. The longest lasted 2.8 days. Every outage, with how long it lasted: Waterval Tower.
JW's end dates
No JW notice we have read stated an end time for this supply. Each end date against what happened: Waterval Tower.
Under strain
In 2026 so far, Bergbron had 17 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. When a supply runs low, the reservoirs and towers around it 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.
