In a very dry state, turning to the sea as a source of water for drinking, bathing and irrigation has its attractions. Desalination is drought-proof - the ocean is one pond we can't empty so quickly. It's more expensive, but the cost is relatively stable, and as technology makes the process more efficient, those costs have been trending downward.
In some of the driest regions of the world, desalination will become an increasingly important source of fresh, potable water. However, the process of separating salt and water is an expensive and energy-intensive one that often includes chemical treatments, thermal distillation and filtration by reverse osmosis.
