ACC was the civil and structural steel contractor for Doosan Heavy Industries for the Umm Al Nar desalination plant, which was completed in 2001.

The plant is able to produce 62.5 MIGD and was built on a fast track basis: out of a total of 65,000 cubic metres of concrete, 50,000 cubic metres were poured in less than five months. Output is achieved through five evaporators (12.5 MIGD each) with five attendant boilers.

The project consisted of five distillers (each 90 metes long, 30 metes wide and weighs 3,500 tons), five low pressure boilers, four water tanks (each 75 metres in diameter), a one kilometre discharge culvert, an outlet structure, five kilometre roadworks, a remineralization plant, a potable water pump station and other balance of plant structures (31 structures in total).
