On Monday, there was still no electricity supply and no water in many villages in the flooded regions of central Greece.
In the port city of Volos, with its 150,000 inhabitants, the water supply network is still so badly damaged that the districts are only supplied in alternation, the news channel ERTnews reported on Monday.
It noted that the water supplied was not potable.
According to the fire brigade, almost 4,500 people have been rescued so far, but the rescue work by the fire brigade and the military is continuing.
People are still missing, and the fire brigade said the death toll from the flood was 15 on Monday.
The extent of the damage cannot yet be estimated because the water is still far from receding in large parts of the affected areas.
From Monday to Thursday last week, a heavy storm depression settled over central Greece.
Heavy rain flooded villages and towns.
Rainfall reached unprecedented levels of more than 700 millimetres in less than 24 hours.
