They say SA is going to run out of water in the near future so why don't they build a couple of Desalination plants near the coast?

We can waste the seas water can we after all there is soooo much of it.
Desalination remains energy intensive! Like i said, for it to work you would also have to ensure losses e.g. due to evaporation is reduced drastically too.. else it increases the losses and remember we already have an energy issue
