Doosan Heavy Industries & Construction Co., South Korea's top power equipment maker, on Monday said it has clinched a 220 billion-won (US$185 million) deal to build a desalination plant. 
Under the deal with the Iran-based Sazeh Sazan, Doosan Heavy will construct the facility by October 2018. The South Korean company will also do operating and maintenance work for 12 years. 
Doosan Heavy's deal marks the first for a desalination plant in the Middle East country after international sanctions on it were lifted earlier this year. 
The facility will process 200,000 tons of sea water into fresh water a day, enough for 670,000 people, according to Doosan Heavy.
