1.2  The different uses of water

Water is used in many ways: for domestic purposes, in industry, in commercial establishments (such as hotels and restaurants), in farming (for agriculture and animal-rearing), and for emergency uses such as fire-fighting. Note that the quality and quantity of water for each use is different. Water for domestic purposes needs to be of high quality but is used in relatively small amounts, whereas usage in industry or agriculture could cope with water of a lower quality but the demand is much higher in terms of quantity.
