SoCal has a very large population of people living largely in arid to semi-desert zones many of whom try to emulate an entirely different climate in their landscaping. It's unsustainable as are all the swimming pools and golf courses. Desalination plants are a good idea, but that water will be more costly. Perhaps it will bring a dose of reality to those who think that they are entitled to vast supplies of water in a place that rarely gets rain and where the aquifers in northern California are being sucked dry by the almond industry in particular.
