Water Desalination Equipment Market Report 2026

The water desalination equipment market size has grown rapidly in recent years. It will grow from $19.23 billion in 2025 to $21.45 billion in 2026 at a compound annual growth rate (CAGR) of 11.5%. The growth in the historic period can be attributed to freshwater scarcity in coastal regions, population growth in arid areas, government investments in water infrastructure, industrial water demand growth, urbanization pressure on water resources.

The water desalination equipment market size is expected to see rapid growth in the next few years. It will grow to $33.05 billion in 2030 at a compound annual growth rate (CAGR) of 11.4%. The growth in the forecast period can be attributed to climate change induced water stress, rising municipal desalination projects, declining membrane costs, expansion of industrial desalination, focus on sustainable water management. Major trends in the forecast period include expansion of large scale seawater desalination plants, growing adoption of reverse osmosis technology, focus on energy efficient desalination systems, integration of modular desalination units, rising demand for industrial water reuse.

The rising depletion of fresh water is expected to support the growth of the water desalination equipment market. As conventional freshwater sources become increasingly scarce and unreliable, demand for desalination technologies continues to rise to ensure a sustainable and secure water supply. Advancements in desalination processes, along with growing consumer demand for safe drinking water, further accelerate adoption. For example, in October 2023, the United Nations International Children’s Emergency Fund (UNICEF), a US-based humanitarian organization, reported that by early 2025, nearly 50% of the global population may be living in regions experiencing water scarcity. By 2030, an estimated 700 million people could be displaced due to extreme water shortages, and one in four children is projected to reside in areas with exceptionally high water stress. Therefore, the depletion of freshwater resources is driving the water desalination equipment market.

Major companies operating in the water desalination equipment market are focusing on developing advanced reverse osmosis (RO) desalination systems. Reverse osmosis is a purification technology that uses a semipermeable membrane to remove salts, contaminants, and impurities from water. For instance, in December 2023, R-evolution, a division of Hexagon AB, launched a new desalination initiative aimed at addressing global freshwater scarcity. The initiative leverages Hexagon’s digital twin technologies to enhance the efficiency, performance, and scalability of desalination plants worldwide.

In February 2023, Gradiant Corporation, a US-based provider of advanced water and wastewater treatment solutions, acquired Advanced Watertek for an undisclosed amount. The acquisition strengthens Gradiant’s manufacturing capabilities and expands its footprint in the rapidly growing Middle Eastern market. Advanced Watertek is a UAE-based manufacturer specializing in membrane-based water treatment systems.
