The graph below shows the location and spread of desalination plants by country. According to the Water Desalination Report, desalinated water is mainly used in the Middle East (mainly Saudi Arabia, Kuwait, the United Arab Emirates, Qatar and Bahrain), which constitutes 70% of global capacity; and in North Africa (mainly Libya and Algeria), which represents almost 6% of global capacity. Among developed countries, the United States is one of the largest users of desalinated water (6.5%), particularly in California and Florida.
