In words
2025 so far: JW reported it at “poor pressure to no water” or “critically low” on 0 days. JW published a report for it on 42 of the 304 days in the record; the other 262 days have no report, and we do not count them as normal. The median supply in the city had 1 such day.
JW's boards first named Erand 1 Reservoir on 3 March 2025 and last on 26 May 2025: 42 statuses on 42 boards, over 42 days. 0 of those statuses announced a scheduled overnight closure, which we count apart, never as an outage.
Month by month
Days JW reported Erand 1 Reservoir at “poor pressure to no water” or “critically low”, out of the days it reported it at all. A month with few reported days says little.

Past outages
Each row is one outage: a stretch of time JW reported Erand 1 Reservoir at “poor pressure to no water” or “critically low”, newest first. An outage has no reported end when JW's reports stopped before it ended, or when it was still going at JW's last report; its length is then a minimum.
JW reported no such outage for this supply.
What JW's boards cannot tell you
- 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.
