Key Facts
- 130 water reports since February 2026 (1.2% of all reports); 47 of them in September
- Most water reports came from the Ionian Islands and Crete (about 29 each), then Central Macedonia (16) and Attica (about 14)
- EYDAP (Athens & Attica): 1022 or 210-2144444 (24/7); EYATH (Thessaloniki): 2310-966600
- Everywhere else: your local DEYA municipal water utility
- Counts do not compare utilities: they depend on where our users are
Water outages are a small share of Outage.gr's data, but they affect daily life more directly than almost anything else. This page sets out what our 130 water reports show, what they cannot show, and who to call when the taps run dry.
The numbers
Since February 2026, Outage.gr has received 130 water reports, 1.2% of the 11,247 total. They grew with the site, and with the summer:
| Month (2026) | Water reports |
|---|---|
| February | 6 |
| March | 2 |
| April | 1 |
| May | 6 |
| June | 10 |
| July | 12 |
| August | 32 |
| September | 47 |
| October (to the 20th) | 14 |
Where the reports came from
The Ionian Islands and Crete each account for about 29 water reports, followed by Central Macedonia (16), Attica (about 14), the South Aegean (about 10), the Peloponnese (9), Epirus (about 6) and Thessaly (4).
Please read that carefully. We cannot conclude that these regions have worse water supply: the counts follow where people use Outage.gr, and a summer rise on islands could reflect tourist demand, drought, or simply more users. We do not know the cause, and we are not going to guess.
Who looks after your water?
Water is local in Greece, unlike electricity, which DEDDIE serves nationwide:
- EYDAP serves Athens, Piraeus and most of Attica. Fault line: 1022 or 210-2144444 (24/7).
- EYATH serves Thessaloniki. Fault line: 2310-966600.
- Local DEYA utilities serve everywhere else, one per municipality. Search "ΔΕΥΑ" plus your municipality name, or ask the town hall for the fault line.
When the water stops
- Fill containers as soon as you hear about a planned cut.
- Do not run a water heater or washing machine until supply is confirmed back.
- After a pipe break, run cold taps for a few minutes before drinking: water can be cloudy from sediment.
- Keep reserves of bottled water for the household (at least a few litres per person per day).
- Call the local utility if it lasts more than a few hours, and ask for an estimate.
What about power cuts and water?
In some buildings, a power cut also stops water because pumps and boosters need electricity. That is a power problem, and a UPS or power-cut kit cannot run a pump, but you can store water in advance.
