Water although the name implies water, Hydra has no natural water available. The water from the taps, etc, is supplied by the mains system via pipes that pump the water from a number of huge tanks above the town. The tanks are replenished on a daily basis with water that is shipped over from the mainland. Some houses on the island have their own fresh water cisternas and the town's water supply is augmented with this collected rainwater.

Understandably water is in short supply and at the height of the season, especially when everyone comes back for a shower in the early evening, houses higher up, tend to find a serious drop in pressure. You will also find that the hot water tanks in most houses are very small, so don't expect the shower to last long and wait for it to reheat between taking turns.
