The global water desalination equipment market size was estimated at USD 18.36 billion in 2024 and is expected to grow at a CAGR of 9.6% from 2025 to 2030. The scarcity of freshwater reserves, coupled with the rising demand for water in various arid regions, as these areas lack sources of surface water such as lakes and rivers, has resulted in increased demand for water desalination equipment globally.
According to the World Economic Forum, global freshwater demand is projected to exceed supply by 40% by 2030, leaving an estimated 1.6 billion people without access to safely managed drinking water. Currently, approximately 4 billion people live in water-scarce regions, and one in four cities faces water insecurity.
As water scarcity intensifies, the demand for desalination equipment is growing to bridge the widening gap between supply and demand. Water is a fundamental resource for daily life and plays a critical role in industrial and construction activities. According to the U.S. Geological Survey (USGS), approximately 71% of the Earth’s surface is covered by water, with 96.5% found in oceans, seas, and bays as saline water. Only 3.5% of the world’s water is freshwater, sourced from groundwater, rivers, streams, and lakes, making its availability and sustainable management crucial for human and industrial needs.
The market growth stage is high, and the pace of growth is accelerating. The water desalination equipment industry is characterized by a high degree of innovation owing to rapid technological advancements. Key trends include intelligent and automated systems, which use IoT-enabled sensors and devices to monitor and control various aspects of the desalination process, such as water quality, energy consumption, and equipment performance. This real-time data collection and analysis enables predictive maintenance, allowing operators to identify and address potential issues before they lead to breakdowns or disruptions. By minimizing downtime and optimizing operations of water desalination equipment, these systems contribute to increased plant efficiency and cost-effectiveness.
Regulations significantly impact the global water desalination equipment market by shaping operational practices and market dynamics. Governments and regulatory bodies around the world enforce stringent standards to safeguard environmental and public health, and these regulations play a critical role in influencing the design, operation, and expansion of desalination facilities.
Regulations regarding the prevention of contaminants, such as brine, can drive up operational costs as companies invest in advanced treatment technologies and systems to comply with these requirements. In regions with rigorous environmental regulations, the increased costs of compliance can slow down the pace of new desalination projects and impact market growth.
The rising population in urban areas worldwide is straining the existing natural water sources. Deteriorating environmental conditions such as altered weather patterns, increased pollution, and deforestation have resulted in water shortages and drought-like scenarios globally. The governments of various countries are investing in the development of desalination plants to counter this challenge, which, in turn, is projected to drive the market growth.
The initial cost of desalination equipment, such as reverse osmosis membranes and multi-stage flash (MSF) systems, can be high. Ongoing maintenance and replacement of components like membranes also add to long-term costs, limiting widespread adoption.
Governments and private entities are focusing on sustainable water solutions, leading to increased investments in desalination infrastructure and equipment. This trend is particularly prominent in regions like the Middle East, Australia, and parts of Europe and Asia.
The seawater segment led the market and accounted for 60.3% of the global revenue share in 2024, driven by the abundance and widespread availability of seawater. As coastal regions face increasing scarcity of freshwater, seawater offers a reliable and consistent source for desalination. The ability to tap into the vast oceanic resources ensures a steady supply of potable water, especially in regions prone to droughts, population growth, and limited access to natural freshwater sources. This makes seawater a preferred choice for desalination, driving its adoption globally.
The brackish water segment is estimated to witness growth at a CAGR of 9.5% over the forecast period. One of the major advantages of desalinating brackish groundwater, compared to seawater, is its recovery rate. Seawater desalination yields around 50% of its volume in freshwater, whereas brackish water yields about 90% freshwater.
The reverse osmosis segment dominated the market in 2024 accounting for 55.9% of the revenue share. Reverse Osmosis is widely adopted due to its energy efficiency, lower operational costs, and the ability to produce high-quality freshwater. Technological advancements in membrane materials and system design have made RO increasingly cost-effective, making it popular for both large-scale and smaller desalination projects.
The adoption of MSF distillation is driven by its ability to handle high salinity levels in seawater, making it ideal for large-scale desalination. Its proven reliability and capacity to operate in various environmental conditions also make it a preferred choice in regions with limited freshwater resources.
The municipal application segment led the market and accounted for 52.2% of the global revenue share in 2024. The municipal sector is responsible for providing potable water to the urban population around the world. Moreover, the growing urban population coupled with expanding megacities globally is anticipated to limit the capacity of municipal sectors to provide water. Thus, this sector is expected to emerge as a key segment that will aid the Water Desalination Equipment growth over the forecast period.
The market for water desalination equipment is witnessing significant growth, driven by increasing demand across various industrial applications. Industries such as power generation, oil & gas, mining, food & beverage, and pharmaceuticals require large volumes of water for operations, making desalination a vital solution in water-scarce regions. In power plants, desalinated water is essential for cooling systems and steam generation, while in the oil & gas sector, it is used for enhanced oil recovery and process water needs.
Middle East & Africa led the water desalination equipment industry and accounted for 49.6% of the global revenue share in 2024. The Middle East & Africa (MEA) market is witnessing significant growth, driven by extreme water scarcity, rapid urbanization, and expanding industrial activities. The Middle East, home to some of the most water-stressed nations, relies heavily on desalination to meet municipal and industrial water demands. Countries such as Saudi Arabia, the UAE, and Qatar have made substantial investments in large-scale desalination projects, utilizing technologies like reverse osmosis (RO) and multi-stage flash (MSF) distillation.
