Source of Water in Chios, Greece

Tap water in Chios comes mainly from local groundwater, extracted through municipal wells and boreholes, together with water from springs. The island has limited surface water, so these underground sources are the main supply.

Desalination plants supplement the network, particularly during dry periods or when demand is high. Before distribution, the water is treated and disinfected by the local water utility.

Chios Drinking Fountains

Public drinking fountains in Chios are generally safe when they are connected to the regulated municipal water supply and clearly marked as drinking water. Greece follows EU drinking water standards, including routine testing for microbiological and chemical safety.

Avoid fountains marked non-potable, damaged, poorly maintained, or with stagnant water around the outlet. When no drinking-water sign is present, bottled water is the safer choice.
