Desalination System Market

The global desalination system market is transitioning from a niche water-supply option to a core pillar of national water security strategies. Driven by accelerating water stress, climate variability and coastal urbanization, desalination systems are now embedded in long-term infrastructure plans across the Middle East, North Africa, Asia-Pacific, North America and parts of Europe.

Based on synthesis of leading industry reports and public-domain data, the global desalination system market is currently valued at around USD 22 billion in 2026 and is projected to expand to approximately USD 55 billion by the early 2030s, implying a robust high‑single to low‑double digit CAGR over the forecast period. Membrane-based technologies, particularly reverse osmosis (RO), dominate installed capacity, while thermal processes retain importance in specific high-salinity and cogeneration applications.

According to Global Infi Research, the desalination system market presents a structurally growing opportunity space, underpinned by:

• Structural water scarcity and tightening water‑quality regulations
• Rapid adoption of energy-efficient RO and hybrid plants
• Expansion of desalination into new segments such as green hydrogen, high‑tech manufacturing and agricultural reuse

Desalination System Market Drivers and Emerging Trends

Core Market Drivers

1. Rising Water Scarcity and Climate Stress

   • Droughts, shifting rainfall patterns and over‑exploited aquifers are pushing governments to secure non‑conventional water sources.
   • Coastal countries in the Middle East, North Africa, Southern Europe, Latin America and Asia-Pacific are prioritizing large‑scale seawater and brackish water desalination as a strategic hedge against hydrological volatility.

2. Urbanization and Municipal Demand

   • Rapid growth of coastal megacities in regions such as the Gulf, India, China and Latin America is driving sustained demand for municipal-scale desalination plants.
   • Long‑tenor public–private partnership (PPP) contracts and build–own–operate (BOO) models provide predictable cash flows, making desalination assets attractive to infrastructure investors.

3. Industrialization and High‑Purity Water Requirements

   • Power generation, oil and gas, petrochemicals, mining, food & beverage, pulp & paper and, increasingly, semiconductor fabrication and pharmaceuticals are turning to desalination and reuse to secure ultra‑pure process water.
   • Zero‑liquid‑discharge (ZLD) and near‑ZLD mandates are becoming more common in Asia-Pacific and Europe, further lifting demand for advanced desalination systems.

4. Falling Specific Energy Consumption and Technology Maturation

   • Continuous improvements in RO membrane efficiency, energy‑recovery devices and plant design have reduced the specific energy consumption for seawater RO to around 3 kWh per cubic metre in many modern plants, compared with much higher levels a decade ago.¹²
   • Integrated solar or wind power with RO is rapidly improving the economics and environmental profile of desalination, making it more competitive against long‑distance water transfer and reservoir expansion.

5. Water Security and National Sovereign Plans

   • National water‑security strategies in Saudi Arabia, the UAE, Israel, Singapore, Spain and Australia, among others, build desalination directly into long‑term supply portfolios.
   • Sovereign funds and state‑backed utilities are increasingly underwriting large-scale projects, reducing project risk for technology providers and EPC players.

Emerging Trends Shaping Market Evolution

• Hybrid and integrated plants (e.g., RO + MED, or RO + wastewater reuse) to optimize energy use, water quality and brine management
• Digitalization and AI/ML for predictive maintenance, dynamic energy optimization and fouling management
• Decentralized and modular systems for islands, remote communities, resorts and industrial clusters
• Green hydrogen integration, where desalination provides feedwater for electrolysis in large coastal hydrogen hubs
