Desalination Technologies Global Market Report 2026

Desalination technologies are processes designed to eliminate salt and minerals from saline water, such as seawater or brackish water, in order to produce fresh water. These technologies play a crucial role in addressing water scarcity and ensuring a sustainable supply of fresh water for various applications, including drinking and irrigation.

The primary technologies employed in desalination include reverse osmosis (RO), multi-stage flash (MSF), and multi-effect distillation (MED). Reverse osmosis (RO) is a water purification method that utilizes a partially permeable membrane to eliminate ions, unwanted molecules, and larger particles from water. Desalination technologies draw water from diverse sources such as seawater, brackish water, river water, and others, catering to municipal, industrial, and other purposes.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report's Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs on desalination equipment, membranes, pumps, and related components have impacted the desalination technologies market by raising capital costs and affecting project timelines, particularly in regions such as the Middle East, Asia-Pacific, and North America. RO and MED systems are among the most affected segments. However, tariffs have also encouraged local manufacturing, innovation in energy-efficient and modular desalination solutions, and investments in cost-optimized technologies, supporting long-term market resilience.

The desalination technologies market size has grown rapidly in recent years. It will grow from $21.49 billion in 2025 to $23.89 billion in 2026 at a compound annual growth rate (CAGR) of 11.1%. The growth in the historic period can be attributed to rising freshwater scarcity in arid regions, growth of municipal water supply demand, expansion of seawater desalination plants, adoption of conventional msf and med processes, increasing industrial water requirements.

The desalination technologies market size is expected to see rapid growth in the next few years. It will grow to $36.69 billion in 2030 at a compound annual growth rate (CAGR) of 11.3%. The growth in the forecast period can be attributed to increasing need for energy-efficient desalination solutions, adoption of advanced ro and hybrid technologies, integration of ai and iot for smart desalination operations, expansion of desalination infrastructure in developing regions, focus on sustainable and low-emission water treatment processes. Major trends in the forecast period include increasing adoption of reverse osmosis (ro) technology, deployment of multi-stage flash (msf) and multi-effect distillation (med) systems, integration of hybrid ro and low-energy desalination processes, growing use of modular and small-scale desalination plants, implementation of smart monitoring and automation in desalination facilities.

The rising water scarcity is expected to drive the growth of the desalination technology market in the future. Water scarcity occurs when the demand for water exceeds the available supply, which can result from physical limitations or insufficient infrastructure and management. Factors contributing to increasing water scarcity include population growth, climate change, water pollution, over-extraction of groundwater, inefficient water use, deforestation, land degradation, and conflicts over water resources. Desalination technology offers a sustainable and reliable source of freshwater, especially in regions experiencing severe water stress and scarcity. This technology plays a crucial role in promoting water conservation and implementing efficient water management practices, which are essential alongside desalination efforts. For instance, in March 2023, the United Nations Educational, Scientific and Cultural Organization (UNESCO), a specialized agency of the United Nations based in France, reported that the global urban population facing water scarcity is projected to reach between 1.7 and 2.4 billion people by 2050. Therefore, the increasing water scarcity is a significant driver of growth in the desalination technology market.

Major companies operating in the desalination technologies market are focusing on developing innovative solutions, such as energy-efficient membranes, to improve water production efficiency and sustainability. Energy-efficient membranes are specially engineered filtration materials used in desalination that minimize the energy required to remove salt and impurities from water while maintaining high water output. For instance, in October 2025, Acciona S.A., a Spain-based renewable energy, water, and infrastructure company, launched dual-model AI technology to enhance desalination efficiency at its reverse osmosis plants. The system combines a simulation-based model for optimizing operational settings with a real-time AI tool that dynamically adjusts parameters to improve energy performance and water output. This advanced approach has been implemented in plants in Qatar, enabling centralized monitoring and enhanced sustainability through ACCIONA's Water Control Centre in Madrid. By integrating predictive modeling with adaptive AI, the technology substantially reduces energy consumption while ensuring high-quality water production.

In May 2023, Xylem Inc., a US-based company specializing in developing innovative water solutions through smart technology, completed the acquisition of Evoqua Water Technologies for $7.5 billion. This strategic move was aimed at establishing the world's largest pure-play water technology company. The acquisition was intended to address customers' mission-critical needs by offering an unparalleled portfolio of products and services. Additionally, it aimed to create a transformative platform to tackle critical water challenges on a larger scale.
