The sea water contains a lot of salt. Believe it or not there already exist a 50 metres long machine that is converting sea water into drinking water. The problem is that it is very expensive to do so. It cost $12 AUD to make a litre of drinkable water because it takes up to three weeks to remove the salt from the water. The Prime Minister of Australia visited the Victoria Water Plant last year but left immediately when he heard about the cost of $12 dollars a litre of drinkable water from sea water.

Because it takes lots of energy to do that, and generating energy costs money and produces pollution. Much better to just be more efficient at catching and using natural fresh water, like from rivers.
