Noordwyk
Last Johannesburg Water (JW) report: Tue 29 Sep 2026, 20:55
Both of Noordwyk's supplies: short of water on 1 and 4 days this year.
Each from 189 days with a JW report. A typical reservoir or tower in the city had 4.
At JW's last report: Supplying fairly (1) Level low (1)
JW lists Noordwyk under both supplies and does not say which streets each one reaches.
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: 4 days short of water for Erand Reservoir, from 189 days with a report; 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 Noordwyk's 2 supplies short of water on 5 days
3 March 2025 to 29 September 2026, from 482 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. Erand Reservoir was low. Erand Tower was supplying fairly. JW reported Erand Reservoir and Erand Tower short of water on 4 and 1 days this year. A typical reservoir or tower in the city had 4 such days. On Erand Reservoir, half of its last 6 outages were over within 23 hours; the longest since March 2025 lasted 2.1 days.
Latest JW report
Erand Reservoir, 29 September 2026: level low at 20:55, the worst status in this report (JW: “Supplying fairly but low”).
JW put it on its website 1 October 2026 at 13:40. JW's page for this board ↗ · JW's image of the board ↗
Erand Tower, 29 September 2026: supplying fairly at 20:55, on bypass (JW: “On bypass. Supplying fairly”).
JW put it on its website 1 October 2026 at 13:40. JW's page for this board ↗ · JW's image of the board ↗
“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.

Where Noordwyk gets its water
Noordwyk draws on two supplies at once: Erand Reservoir and Erand Tower. JW does not say which street each one reaches.

JW fills this tower from Erand Reservoir, which also supplies Noordwyk: “The Erand 1 Reservoir level is satisfactory, hence pumping to the tower is in progress.” JW ↗ Source 1 ↗ Source 2 ↗ |
Outages
JW reported 7 outages on Noordwyk's supplies since March 2025. The longest lasted 2.1 days. Every outage, with how long it lasted: Erand Reservoir and Erand Tower.
JW's end dates
JW posted 18 notices with an end date that list a suburb or system Noordwyk'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 26 end times that have passed. Each end date against what happened: Erand Reservoir and Erand Tower.
Under strain
In 2026 so far, Noordwyk 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. Noordwyk 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.
