Hung Long Co, which made the plant, said the cost was 40 to 60 percent lower than that of an imported plant.
The reverse osmosis process it uses filters substances like nitrate, metal ions, organic dirt particles, and bacterium, making seawater potable.
The plant was set up under a city program to make equipment domestically at lower cost instead of importing, and was aimed at reducing the annual expenditure of VND17 billion (about US$1 mil) on supplying fresh water to water-starved Can Gio.
