South Korea’s Doosan Heavy Industries & Construction Co. won a 220 billion won ($185.9 million) worth order from Iran-based Sazeh Sazan Co., to build a seawater reverse osmosis desalination (SWRO) plant in the Middle East country.

The company said Monday that the deal marks the first SWRO procurement a foreign company clinched from Iran since international sanctions were lifted early this year.

The plant – dubbed SAKO SWRO plant – will be built at Bandar Abbas, the capital of Hormozgan Province in Iran. It will desalinate around 200,000 tons of water a day, which would be supplied to mines in the region in annual capacity enough for 670,000 people after its construction is completed in October 2018. Doosan will be in charge of engineering, procurement, construction and test operation of the facility and also provide operation and maintenance (O&M) services until October 2030.

Yoon Seok-won, the executive vice president and CEO of Doosan’s Water BG, said that the latest deal was product of persistent and all-around endeavors. The company signed a Memorandum of Understanding (MOU) agreement with Iranian National Water and Wastewater Engineering Company (NWWEC) in April. President Park Geun Hye’s state visit to Iran in May served as an impetus. He added that the company will keep up its efforts to cement its foothold in the Iranian reverse osmosis desalination market, which is expected to reach $2 billion by 2018.
