Source of Water in Firostefani, Greece

Tap water in Firostefani is supplied by the Municipal Water and Sewerage Company of Thera, which serves Santorini. The main source is seawater treated by local desalination plants.

Local groundwater wells and storage facilities also supplement the supply. Because Santorini has limited, naturally mineralized groundwater, desalination is essential for the island’s public water system.

Firostefani Drinking Fountains

Public drinking fountains in Firostefani are safe to use when they are clearly marked as drinking water fountains and are connected to the treated public supply. Greece follows European Union drinking-water standards, including testing for bacteria and chemical contaminants.
