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: 87 days short of water for President Park Tower, from 189 days with a report; 35 days for President Park Reservoir, from 189; 6 days for Grand Central Tower, from 189; 4 days for Erand Reservoir, from 189; 4 days for Rabie Ridge Reservoir, from 189; 3 days for Grand Central Reservoir, from 189; 1 day for Erand Tower, from 189. 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 Glen Austin AH's 7 supplies short of water on 95 days
3 March 2025 to 29 September 2026, from 1,855 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.
Is anyone fixing it?

“On bypass” is JW's term. When JW repaired Hursthill 2 Reservoir from December 2025, it put the reservoir on bypass so that teams could work safely inside, and customers still received water; the news reports said this could bring periods of low pressure or no water (EWN ↗, The Citizen ↗). A reservoir or tower on bypass does not count as back when this page checks JW's end dates.
Glen Austin AH draws on seven supplies at once: Erand Reservoir, Erand Tower, Grand Central Reservoir, Grand Central Tower, President Park Reservoir, President Park Tower and Rabie Ridge Reservoir. JW does not say which street each one reaches.
Listed on JW's pages, as Glen Austin A.h.. JW fills this tower from Erand Reservoir, which also supplies Glen Austin AH: “The Erand 1 Reservoir level is satisfactory, hence pumping to the tower is in progress.” JW ↗Source 1 ↗
On JW's list of towers, June 2024, as Glen Austin A.h.. JW fills this tower from Grand Central Reservoir, which also supplies Glen Austin AH: “The level of the Grand Central Reservoir was stable overnight. The reservoir is pumping to the tower but will be stopped once the threshold is reached.” JW ↗Source 1 ↗
Glen Austin AH's supplies are in JW's Midrand system.

No JW report for taps. See the supplies above: when they are supplying, a tap can still be dry, most often in higher streets.

Under strain
In 2026 so far, Glen Austin AH had 113 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. Glen Austin AH 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.
