Intensive industrilisation and urbanization have caused great pressure on the existing freshwater resources in the following ways :
(i) Water is used in industries in many ways. It is used as a coolant for machines.
(ii) Water is required to generate hydroelectricity, to run industries as well as homes.
(iii) As a result of the rapid increase in population and urbanization, the per capita consumption of water has also increased. Water is therefore, critically short of supply.
