Construction completed for Shuqaiq 4 desalination plant

11 November 2025

Construction and commissioning works on Saudi Arabia's Shuqaiq 4 desalination plant have been completed, according to Spain's Acciona.

Located on the Red Sea coast, the seawater reverse osmosis facility has a capacity of 400,000 cubic metres a day (cm/d) and will provide potable water to about 3.5 million people.

The main contract for the project was awarded in 2021 by the Saline Water Conversion Corporation to a consortium of Acciona and local partner Al-Rashid Trading & Contracting.

The facility is located adjacent to the operational Shuqaiq 3 independent water project (IWP), a separate project and Saudi Arabia’s second IWP. 

The main contract was awarded by Water & Electricity Company – which is now known as Saudi Water Partnership Company (SWPC) – in January 2019 to a team led by Japan’s Marubeni and the local Abdul Latif Jameel.     

The consortium also comprises Acciona and the local Rawafid Al-Hadarah Holding Company.

Together, the two plants add nearly 850,000 cm/d of capacity to the national network, including Jizan, Asir and surrounding regions.

Additionally, SWPC is planning to undertake the construction of the Al-Shuqaiq 4 IWP, including a desalination facility with a capacity of 400,000 cm/d. 

Almost 40 companies have submitted statements of qualifications. The main contract has yet to be tendered.
