Executive overview
Why this report matters
Summary Insight: Desalination is becoming a climate-independent component of national water security and integrated utility planning. Transformation is being delivered through reverse osmosis, private finance, clearer governance, renewable integration, and circular brine management. Global installed capacity reached approximately 130 million m3 per day in 2026, SWRO represents 95.6% of newly contracted capacity, and Saudi Vision 2030, the Global Clean Water Desalination Alliance, and the California Ocean Plan are shaping implementation. This strengthens resilience against future climate, demand, and environmental pressures.
This report evaluates the technologies, governance structures, financing models, energy pathways, and environmental controls determining whether seawater and brackish water desalination can scale as resilient baseline infrastructure.
Forecast annual global desalination capital expenditure by 2030, associated with a 12% annual growth rate from 2024 and forecast OpEx of USD 15.2 billion.

Buyer relevance
Who the report is for
- Utility Executives & System Operators: Understand how reverse osmosis is reshaping desalination system architecture, operating efficiency, and climate-independent supply planning.
- Regulators & Policymakers: Examine how the California Ocean Plan informs discharge regulation, environmental monitoring, and accountable brine management.
- Infrastructure Investors & Financiers: Assess how USD 11.7 billion in forecast annual CapEx affects project bankability, procurement risk, and capital allocation.
03
Decision scope
Questions answered
How much desalination capacity is installed globally?
Approximate global installed desalination capacity reached 130 million m3 per day in 2026. This is supported by the reported 130 million m3 per day capacity benchmark. National-scale deployment is being advanced through programmes including Saudi Vision 2030.
Which technology dominates new desalination contracts?
Seawater reverse osmosis dominates newly contracted desalination capacity. This is supported by SWRO representing 95.6% of newly contracted capacity. Deployment is enabled through BOO and BOOT procurement mechanisms.
How large could annual desalination investment become?
Annual global desalination capital expenditure could reach USD 11.7 billion by 2030. This is supported by a forecast 12% annual CapEx growth rate from 2024. Investment is mobilized through long-term BOOT and take-or-pay structures.
What environmental constraint does the report emphasize?
The report emphasizes energy-related emissions and hypersaline brine discharge. This is supported by 142 million m3 per day of reported global hypersaline brine discharge. Environmental controls are advanced through mechanisms including the California Ocean Plan.
