Modern water systems for residential units normally include a plastic water tank mounted on the roof which provides water for the house or flat. The water is either piped in or the tank must be filled each week or so by trucked-in water. There are several "tricks" to learn about the system. Refrigerated tank water is rare, so during the summer the water in the tank becomes extremely hot due to the external temperatures. This is the water which flows to the showers, sinks and toilets.
Generally, people do not drink "tap" water, but buy bottles or have spring water delivered in five gallon drums that fit into a water machine. The tap water is safe as far I as know.
