Water to drink is usually provided from a mains pipe into ONE tap in the kitchen.
Many houses do not have the third tap in the kitchen. I do not necessarily advocate using the cold water tap from the roof tank but many people do without problems, because the mains water often has excess chlorine which kills off any bugs that might develop in the roof tank. This assumes constant daily use of water for showers etc. Do NOT do this unless you have a daily consumption of water (i.e., constant occupancy).
Quite a large proportion of the population purchase so-called mineral water (Greek or Cypriot, for the most part) in half litre or 1 1/2 L bottles for drinking water. These are handy to have in the fridge.
A third possibility is to use 25 L bottles in a dispenser of both hot and cold water – not very practical unless your supplier changes your bottles regularly because of the weight of the full ones.
Number four on the list is a below-the-kitchen-sink device for sterilising water, requiring maintenance.
A fifth choice would be a full-scale water purifier under the sink, costly to buy and run and not really serving much useful purpose other than to make the drinking water horrible to taste!
There, again, your choice from the six possibilities above may require rethinking if your water supply is very hard. Be aware that mains water may come from a dam when water is abundant or it may be re-mineralised ultrapure water when the dams run close to dry. Do not rely upon thinking that tap water is a constant: it ain't!
