Water from the Sea: The Middle East Desalination Build-Out in Numbers
The facts, figures and project pipeline behind the Gulf’s race for water security.
Executive Summary
Desalination has moved from background infrastructure to the front line of Gulf economic and security policy, and the numbers explain why. The Middle East holds more than half of global desalination capacity, its regional installed base passed 52 million m³/day in 2024, and the region is on track to contract a further ~20.9 million m³/day between 2024 and 2028 — roughly 53% of all new capacity worldwide. The build-out is skewing decisively toward reverse osmosis, increasingly paired with solar power and, at the frontier, brine valorisation.
Gulf Reliance on Desalinated Water
The Arabian Peninsula has almost no renewable freshwater, so desalination is a survival requirement rather than an option. Reliance ranges from around 90% of municipal water in Kuwait and Oman to roughly 70% in Saudi Arabia; in the UAE, desalination supplies about 42% of total water requirement from more than 70 major plants.
Market Size & Capacity Growth
One market assessment values the Middle East desalination-plants market at roughly USD 8.3 billion in 2023, rising to about USD 15.5 billion by 2030 at a ~10% CAGR. Regional installed capacity climbed from about 40 million m³/day in 2020 to over 52 million in 2024, and the contracted pipeline points toward the low-70s million m³/day by 2028.
The Project Pipeline
The pipeline is concentrated in Saudi Arabia and the UAE and dominated by large reverse-osmosis IWPs procured through SWPC and EWEC. Abu Dhabi’s Taweelah RO (909,200 m³/day) is the world’s largest operating RO plant; Saudi Arabia’s NEOM targets up to 1–1.5 million m³/day of renewable-powered capacity by 2030.
Technology & Capacity Share
Thermal desalination (MSF/MED) is effectively closed to new build; reverse osmosis now accounts for more than 60% of new projects, cutting energy use sharply, especially when combined with pressure-exchanger energy recovery and dedicated solar. At the country level, the GCC holds roughly 45% of global capacity, with Saudi Arabia alone accounting for around 20%.
STRAGO Perspective — Talent & Advisory Implications
A multi-year, RO-weighted pipeline of this scale generates sustained demand for scarce, mobile expertise across the project lifecycle — much of it directly adjacent to STRAGO’s existing desks.
● Engineering & operations: RO process, membrane and pretreatment engineers; energy-recovery and high-pressure rotating-equipment specialists; plant O&M leadership.
● Commercial & structuring: IWP/PPP developers, project-finance and offtake structuring, and localisation (Saudisation / in-Kingdom content) leads for SWPC and EWEC requirements.
● Digital-infrastructure convergence: Water-positive data-centre concepts link the Digital Infrastructure practice to the same client base.
