Saudi Water Partnership Company (SWPC), the principal off-taker for water and wastewater projects in Saudi Arabia, on Monday named the consortium of ACWA Power, Haji Abdullah Alireza & Co (HAACO) and Al Moayyed Contracting Group (AMCG) as the preferred bidder for its Rabigh 4 Independent Water Plant (IWP) project.

The project, located in Rabigh, 180 kilometres northwest of Makkah, on the Red Sea coast, involves the construction and operation of a 600,000 cubic metres per day (m3/day) desalination project and storage tanks with a total capacity of 1,200,000 m3 as well as extension and connection to the existing electricity transmission substation.

SWPC said in a statement the preferred bidder submitted levelised water cost tariff of 1.7162 Saudi riyals/m3, equivalent to $0.46/m3, for the reverse osmosis (RO)-based desalination project.

The consortium of Acciona Agua and Ajlan & Bros, which was named as the reserve bidder, submitted a tariff of 2.0386 riyals/m3 or $0.54/m3.

The IWP is expected to start commercial operations in the fourth quarter of 2025.

In November 2021, Zawya Projects had reported that SWPC had prequalified eight bidders for Rabigh 4 IWP.
