Reservoirs, 2025
JW reported Hursthill 2 Reservoir short of water on 32 days in 2025, the most of any reservoir
Every reservoir JW reported on in 2025 so far, by the days JW reported it short of water, most first. The number at the right is the days it was reported on: a short record cannot look like good service. The rule is the city median for all supplies. The ranking counts reports; it does not say why. 65 reservoirs.

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.
