Executive summary
Industry Landscape
Desalination capacity continues to expand in water-stressed regions, with reverse osmosis technology accounting for the large majority of new capacity additions due to its lower energy intensity relative to legacy thermal desalination processes still operating across parts of the Gulf.
Key Growth Drivers
- Gulf water security strategy: Saudi Arabia and the UAE continue to expand desalination capacity as a core pillar of national water security planning.
- Reverse osmosis technology shift: RO’s lower energy intensity compared to legacy thermal desalination is driving the large majority of new capacity additions.
- Post-oil economic diversification: Desalination investment is increasingly framed as part of broader Gulf economic diversification and sustainability strategies.
- Water stress in new markets: Countries across the Americas, Asia and Africa are increasingly turning to desalination amid rising water scarcity pressures.
Key Structural Trends
The database tracks facility-level detail including capacity in cubic meters per day, technology type, owner/operator, and commissioning status, with regional breakdowns highlighting the concentration of mega-scale capacity in Saudi Arabia and the UAE alongside significant municipal capacity in the United States, Australia, and Spain.

Research Methodology
The Global Desalination Plants Database is developed using a structured, multi-source research process designed to ensure accuracy and consistency across every tracked record.
Step 1: Scope Definition & Universe Mapping
The research team defines the full universe of desalination plants to be tracked within scope, drawing on regulatory filings, industry association membership lists, company disclosures, and prior desk research to establish an initial master list.
Step 2: Data Collection & Verification
Each record is populated using primary sources including company announcements, regulatory and permitting filings, government databases, and, where available, direct outreach to operators and developers, cross-checked against secondary sources such as industry reports and trade press coverage.
Step 3: Classification & Standardization
Records are standardized into a consistent schema covering location, capacity or scale, ownership, operational status, and timeline detail, allowing like-for-like comparison across all covered countries and regions.
Step 4: Quality Review & Update Cycle
The database is reviewed on a periodic basis to reflect newly announced projects, status changes, and ownership updates, with the 2026 reference year reflecting the most recent verified data snapshot at time of publication.
