Unreliable water source

Even in countries where most residents are connected to a water supply network, there may be frequent interruptions in supply. In southern Russia, water may be available for only a few hours a day. In Romania, some supply systems do not function for more than 12 hours a day. Around 30% of Italy's islanders also suffer interruptions in their water supply.
