Source of Water in Kefalos, Greece
Kefalos’s tap water is delivered through the municipal water network operated by the Kos Water and Sewerage Company (DEYAK). Its supply comes from local groundwater wells and desalinated seawater.
Desalination helps supplement Kos’s limited freshwater resources, particularly during periods of high demand. The water is treated before it enters the distribution network.
Kefalos Drinking Fountains
Public drinking fountains in Kefalos are not automatically guaranteed to be safe; use one only if it is clearly marked as drinking water and appears maintained. If its status is unclear, choose bottled water, as Greece’s regulated water standards do not guarantee that every public fountain is potable.
