Beyond municipal treatment, what compromises Bali's tap water quality?

Answer

The distribution system including pipes and storage tanks

Even if the water entering the municipal supply system undergoes initial treatment to remove immediate dangers, the journey to the consumer's faucet introduces significant risk. The distribution network, which comprises the network of pipes, localized storage tanks associated with buildings, and the final connection points, is often cited as a major source of contamination. These older or poorly maintained components can introduce bacteria or other foreign materials into the water before it ever reaches the tap in a hotel room or rental property, making pre-treatment effectiveness unreliable for tourists.
