Larsen & Toubro’s Water & Effluent Treatment (WET) business, in partnership with Spain’s Lantania, has secured a significant contract from ACWA Power to construct the Ras Mohaisen Desalination Plant in Saudi Arabia. The project, valued between $300 million and $600 million, will involve the design, procurement, construction, testing, and commissioning of a seawater reverse osmosis desalination plant with a capacity of 300,000 cubic meters per day.
The scope of the project includes the development of intake and outfall facilities, process units, pumping stations, and potable water storage with a total capacity of 600,000 cubic meters. Advanced automation and instrumentation systems will be implemented to enhance operational efficiency, while a dedicated solar photovoltaic plant will contribute to sustainable energy use.
Once operational, the desalination facility will supply drinking water to the Makkah Al-Mukarramah and Al-Baha regions, benefiting approximately one million people. This project marks L&T’s second major desalination contract in Saudi Arabia, reinforcing the company’s expanding presence in the Middle East’s water infrastructure sector.
