Although covering some 70% of the Earth's surface, most water is saline. Freshwater is available in almost all populated areas of the earth, although it may be expensive and the supply may not always be sustainable. Sources where water may be obtained include:
- ground sources such as groundwater, hyporheic zones and aquifers.
- precipitation which includes rain, hail, snow, fog, etc.
- surface water such as rivers, streams, glaciers
- biological sources such as plants (See Gathering water from plants)
- the sea through desalination
- Water supply network[1]
