Very interesting. But it looks like this hasn't been done yet - are you aware of pilot projects or anything like that?
See the Appropedia page
Desalination for some of the problems with desal. Until such time as a cost-effective, environmentally friendly method is proven to work, and we know how to safely dispose of a very large volume of deoxygenated brine waste, we're better off sticking to other sources, where possible.
Existing dams (not new ones - they're an ecological disaster), groundwater, rainwater and water recycling should be considered. And most importantly -
Water conservation.
