Top 5 leaders in the global desalination market

Countries that are dramatically impacted by the growing populations and drought have taken important decisions and strode towards a whole new pursuit with pride. They have taken drastic steps in creating sources of accessible water for their country with the establishment of the Efficient Desalination plants and more such renewable resources to purify water. Here we have listed the leading countries in the desalination market.

World’s first desalination plant was fabricated in Australia in the year 1903 due to which seawater and brackish groundwater became a common resource of drinking water supply in the country. Later, other countries in the world took ideas from the concept and started to have their modified versions of water desalination plants. In this article, we will talk about the different countries that are leading today in the establishment of Desalination Plants. Read on to know about it in detail.

Within the last ten years, the growth rate of Australia’s population has decreased below 1%. Also, the water resources in the country were imperiled because of the Millennium Drought, which further
exposed the country to water scarcity issues. Although Australia is the driest continent in the world, the installation of Efficient Desalination plants has transformed the scenario. According to the National Center of Excellence in Desalination (NCED), the establishment of desalination plants in the country can help eliminate the current water-crisis faced.

Australia is the first country in the world to have accepted the methods of water desalination, and the first-ever plant was constructed in 1903 to treat the brackish groundwater and was made drinking water efficiently. Further, in 2013, about 219 desalination plants were fabricated in the driest continent. And according to the reports of the Global Water Intelligence, the plants in Sydney, Gold Coast, and Perth serve more than 17% of the domestic water requirement in Australia.


In the past few years, Israel has experienced that the demand for domestic water consumption has increased gradually due to a significant increase in the growth rate of the country’s population. The increase in population is both due to immigration and natural habitation. Also, the living standards of
the citizens of Israel have increased, resulting in increased demand for domestic water. Therefore, the country now relies on Efficient Desalination plants to provide fresh water for the household as well as extensive agricultural purposes.

Israel has experienced recurring drought situations in the past few years, causing the groundwater to dry up. Hence, the establishment of the desalination plants has served the nation in many efficient
ways. Due to technological advances, Israel has been successful in reducing the cost of desalination of seawater, which has further incentivized the policymakers to invest in the building of desalination plants to cope well with the long-term water shortage issues, which prevailed in the country.

3-Saudi Arabia:

The annual water demand of Saudi Arabia is 24km 3 /year, yet the amount of renewable freshwater resources is limited to 2.4km 3 /year. And the Global Water Intelligence (GWI) suggests that the remaining water requirement is being compensated by desalination plants and non-renewable groundwater
sources. However, over the past few years, the sources of non-renewable groundwater have been declining, and the Efficient Desalination plants are meeting up the ends to satisfy the water demands of the country.

Also, the geographical location of the country is assisting it in enhancing the production of desalinated water using solar energy. The government of Saudi Arabia has heavily subsidized the establishment of desalination water plants throughout the country. Also, the production, distribution, and transportation of gallons of water is being carried out by the government, which is why the cost of desalinated water in the country is meager as compared to any other nation in the world.


The water sector in the USA is facing tremendous challenges as the supplies are falling short, while the demand for water is increasing exponentially. Additionally, recent droughts are depleting the aquifers, whose rate is way faster than the replenishment process. Therefore, the desalination of brackish water could help in a dramatic increase in water levels in the country’s portfolio and serve as a buffer to the water scarcity crisis in the US.

If we look at the desalination capacity of the USA when calculated annually, is positioned in the second rank in the desalination market, globally. Yet it leads in regards to the number of Efficient Desalination plants operating in the nation. More than 80% of the desalination plants of the United States are concentrated in parts of Florida, California, and Texas.


According to the Ministry of Water Resources of China, the country is soon about to face water scarcity levels in a few years of time. The withdrawal level of water is estimated to be 700-800 km 3 /year, which will drastically exceed the level of available water resources in China. Even if practices for conserving water were in place, it wouldn’t be sufficient to satisfy the water requirements of the country.Therefore, the country is now taking significant measures to introduce desalination plants.

The country is being exposed to the adverse effects of water scarcity because of the growth in its population, urbanization, and industrialization. Notably, the Northwestern and Northern regions, the islands in the Northern country, and the coastal cities will be immensely affected due to this issue.
Therefore, the government of China is now adopting several methods to introduce Efficient Desalination plants in the country to combat the water depletion issues. Many cost-effective techniques are also being discovered to administer this upcoming issue of water scarcity in China.

Bottom Line:

All five countries listed here demonstrate a distinctive demand for the introduction of newer water technologies. And all of them have adopted various approaches and taken different ways to foster and promote Efficient Desalination plants. Many cost-effective methods are being identified as well to meet with the demands of their country-people. The five countries are leading in the list of the desalination
market. As a matter of fact, we can decipher here why the requirement of seawater desalination plants so crucial in these regions.

In this article, we have not only talked about the leading countries that are adapting desalination techniques to obtain freshwater but also have highlighted –what is the underlying reason behind it. And as we all know –water scarcity is one of the biggest problems, even the superpowers of the world are combating with.
