• Waste Water- Market Size & Forecast 2020-2030, USD Million
• Others-Market Size & Forecast 2020-2030, USD Million

Seawater holds the largest market share of approximately 47% of the total water treated globally. This is due to the abundant supply of seawater. More than 95% of the water on Earth is present in oceans and seas. Thus, it is an easily accessible water body worldwide. Moreover, seawater is present on the surface, hence, it does not disturb the groundwater level. Henceforth, the treatment of seawater is a feasible solution. Additionally, in the coastal regions, seawater can be easily transported to the plants. Thus, increasing the desalination of seawater.

By System Configuration

• Standalone System- Market Size & Forecast 2020-2030, USD Million
• Integrated System- Market Size & Forecast 2020-2030, USD Million

• Domestic-Market Size & Forecast 2020-2030, USD Million
• Others-Market Size & Forecast 2020-2030, USD Million

The Municipality segment has the largest market share with more than 30% of the total. This market share is observed due to its water supply management for several sectors. In various regions, such as hills, water-scarce areas, etc., where freshwater or drinkable water is not accessible, the municipal corporation provides desalinated water to households. Moreover, municipal corporations also supply this treated water to industries, where voluminous water is required for cooling systems, etc.

By Region

• North America
• South America
• Europe
• The Middle East & Africa
• Asia-Pacific.

The Middle East & Africa region is the fastest-growing region, holding more than 35% share of the total market. This is due to water scarcity, consumer inclination towards sustainability, and others. The Middle East & Africa region has deserts such as the Sahara, Arabian, and Syrian, which account for nearly 75% of the region’s land. This results in the arid climate prevailing over the region. Hence, the countries in this region require desalination of water for basic needs.

These divisions help clarify demand patterns and expected shifts.

Market Opportunities

Government Initiatives to Support Renewable Sources – The ecological disturbances have led worldwide government officials to undertake initiatives such as Energy Strategy 2050 and others. This strategy is initiated by the UAE authorities, under which they aim to achieve at least 50% of the energy produced from renewable resources. To meet this aim, the government is providing subsidies and tax relaxation on the production of electricity from renewable sources.

Moreover, the government and non-profit organizations are investing in developing the clean energy ecosystem across the globe. For instance, the United States officials had invested more than USD300 billion in 2024 to support energy production from renewable sources and conserve fossil fuels. Apart from these, several renewable energy collaborative projects are undergoing. Thus, this support from the officials and organizations creates an opportunity for solar water desalination manufacturers to enlarge their business globally.

Solar Water Desalination Plant Industry Prime Challenge

High-Installation Cost and Unpredictable Weather – The solar water desalinator comprises solar panels, pumps, and several other components. The cost of these solar panels and high-power water pumps is relatively high. Thus, this increases the price of the installation of these plants. Hence, the middle-income consumers do not prefer solar water desalination. As a result, the population is inclined towards pocket-friendly water desalinators and consumes conventional desalinators.

Moreover, solar water desalination is dependent on solar power to empower such plants. Thus, on lower sunlight days or on windy days, when a sufficient amount of sunlight is not accessible, it reduces the efficiency of the solar water desalinators. Thus, this restrains the market growth of solar water desalination globally.
