Doosan Heavy Industries & Construction Co., a major South Korean plant builder, said Monday it has clinched a 780 billion-won ($707.8 million) deal to build a seawater desalination plant in Saudi Arabia.

Doosan Heavy has inked a deal to build the Yanbu-4 facility with a consortium of French energy company Engie SA and Saudi Arabian firms Mowah and Nesma, the company said in a statement.

The facility will be built in Alrayyis, some 260 kilometers north of the western port city of Jeddah, with a capacity of producing 450,000 tons of fresh water per day. Doosan Heavy plans to complete the construction by 2023.
