Together with its partner SEPCOIII, ACCIONA will undertake the construction of the Jubail 3B desalination plant. Its capacity of 570,000 m3/day will supply 2 million people in the cities of Riyadh and Qassim.

The plant will be located in the industrial city of Jubail on the Arabian Gulf coast in eastern Saudi Arabia, around 100 kilometres from Dammam. ACCIONA previously built the Jubail desalination plant on the same site.


The plant is currently under construction and is scheduled to be commissioned in the first quarter of 2024. In addition, the BOO (Build-Own-Operate) contract includes a 25-year plant operation period.


With this contract, ACCIONA consolidates itself as one of the main water treatment infrastructure companies in one of the areas with the highest water stress on the planet, the Middle East, and more specifically Saudi Arabia.


Once Jubail 3B is completed, ACCIONA will supply around 2.37 million m3/day of desalinated water using reverse osmosis, consolidating it as the most efficient and sustainable desalination technology with the smallest carbon footprint.

The project will include storage tanks for daily production, as well as a solar energy plant to reduce the consumption of power from the grid. To do this, ACCIONA will also build a photovoltaic solar plant. The EPC contract will also include the construction of 58 kilometres of power lines, an electricity substation and the associated marine works.

ACCIONA will undertake the construction of the entire reverse osmosis system, including the civil works and the pumping of raw water.
