Global water crisis fuels surge in desalination plants

The rise in the global demand for clean water has led to a record increase in fresh water processed from sea water. Global water shortages are driving the demand.

 Analysts Global Water Intelligence say around 9.5m cubic metres of fresh water a day is produced as a result of desalination or by reusing sewage water. This process is energy-intensive and has mainly been used by Gulf states. But the falling cost of technology means poorer countries such as India, Ghana and Algeria are using these techniques as rivers and dry up and rainfall becomes less predictable. Environmental group WWF has voiced concerns over the manufacture of water as facilities are often built in environmentally fragile costal and wetland areas.
