A WATER company is considering building a £20m plant to convert sea water into drinking supplies.
Southern Water, which treats waste water from homes around the Portsmouth area, says a desalination facility would ease water shortages.
The company, which also supplies water to other places in Hampshire, is carrying out an environmental impact assessment on the scheme to build a plant in Southampton.
It would produce around four million gallons of water a day for the city and parts of the Isle of Wight during times of low rainfall.
Southern Water says that if it goes ahead the plant should be ready by 2028.
