Award nears on ‘world’s largest desalination plant’

21 July 2025

 

The Iraqi government has approved the award of the contract to build what will be the world’s largest desalination plant, sending its decision to the project client to conclude negotiations with the selected contractor consortium. 

The grouping of Power Construction Corporation of China (PowerChina) and the local Al-Rida Group has been in talks with the Basra Governorate for over a year regarding the contract, which the authorities say has an estimated capital expenditure (capex) of $3.9bn. 

It is unclear when exactly the final contract will be signed, but in a public statement Prime Minister Mohammed Shia Al-Sudani said that the Council of Ministers had approved the project, and that the governorate is now “authorised to conclude the contract with the implementing company after completing all technical and administrative requirements”.

The 1 million cubic-metre-a-day reverse osmosis (RO) complex at Basra will be located in the Al-Faw Grand Port development area. 

It includes a 240-kilometre transmission system that will transport potable water to nine off-take stations, which link to the municipalities.

MEED understands that a 300MW captive power plant will produce the required energy for the plant.

Austria’s ILF Consulting Engineers is the project consultant. 

The massive complex is believed to be the world’s largest single-technology desalination plant ever built in one phase. Although there are larger desalination plants in Saudi Arabia and the UAE, they comprise a combination of hybrid technologies and were built in multiple stages.

The long-awaited Basra project has had a complex history, and a successful conclusion of the contract is by no means assured.

Various contracting groups have been associated with it since 2019, including the UK’s Biwater and South Korea’s Samsung C&T.  

Responsibility for the project was transferred from the Ministry of Construction, Housing, Municipalities & Public Works to the Basra Governorate last year as a means of completing it.

There is a pressing need for additional desalination capacity in Iraq. More than 90% of its water needs are met by the Euphrates and Tigris rivers, and thus depend on their sources in Turkiye.  

In periods of drought or low rainfall when its northern neighbour has to extract more water from the rivers than normal, Iraq suffers a severe shortage. Desalination plants on the Gulf coast will therefore alleviate any potential future water supply disturbances, particularly in the south, and are consequently considered a national strategic priority.
