Source of Water in Hydra, Greece

Tap water in Hydra, Attica, comes mainly from seawater desalination plants on the island. The desalinated water is stored in local reservoirs and distributed through the municipal network.

During periods of high demand or limited production, Hydra’s supply can also be supplemented by potable water transported from the mainland by tanker. The island has limited natural freshwater resources, so desalination is its primary source.

Hydra Drinking Fountains

Public drinking fountains in Hydra are generally safe to use when they are clearly marked as drinking water and connected to the municipal supply. The island’s treated water is subject to Greek and European drinking-water standards.

Avoid fountains marked non-potable, decorative fountains, or those that appear poorly maintained. Use bottled water instead if the water is discolored, has an unusual odor, or the fountain is not operating normally.
