Greenstone Park
Last Johannesburg Water (JW) report: Mon 26 May 2025, 21:45
JW has not reported Greenstone Park's supplies on its status boards this year.
JW lists Greenstone Park 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

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.

Where Greenstone Park gets its water
Greenstone Park draws on two supplies at once: Modder Hill Reservoir and RW1963 Direct Feed. JW does not say which street each one reaches.

Outages
JW reported no outage on these supplies since March 2025. Every outage, with how long it lasted: Modder Hill Reservoir and RW1963 Direct Feed.
JW's end dates
JW posted 3 notices with an end date that list a suburb or system Greenstone Park'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 2 end times that have passed. Each end date against what happened: Modder Hill Reservoir and RW1963 Direct Feed.
Under strain
In 2025, Greenstone Park had 0 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. Greenstone Park 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.
