Is Serifos Tap Water Safe To Drink?
Yes! The tap water is safe to drink.
Tap water in Serifos is generally safe to drink when supplied through the municipal water network. It is regulated under Greek and European Union drinking-water standards.
Water quality can vary in taste and mineral content, especially during the busy summer season when demand rises. Properties using private storage tanks or wells may have different water quality, so bottled water is a sensible option in those cases.

Source of Water in Serifos, Greece
Tap water in Serifos comes mainly from local groundwater, drawn from wells and boreholes on the island. The water is stored in municipal reservoirs before being distributed through the public network.
During dry periods and the summer tourist season, Serifos supplements local supplies with desalinated seawater and, when needed, water brought in by tanker.
Serifos Drinking Fountains
Public drinking fountains in Serifos are generally safe to use when they are connected to the municipal water supply and clearly marked as drinking water. Greek public water supplies are required to meet national and European drinking-water standards.
Avoid fountains marked non-potable, untreated spring outlets, or those that appear poorly maintained, especially after heavy rain or long periods without use. When no status is shown, use treated tap water from an accommodation or food-service establishment instead.
