As far as I can tell there is no negative aspects... just positives aspects.
Energy consumption; Reverse Osmosis technology uses the least amount of energy, however still uses large amount of 3 KWh to 10KWh of electric energy to produce one cubic meter of fresh drinking water.
Maintainability; Reverse Osmosis membranes could “clog up” with dissolved salts, or could grow bio-fouling. They need to practice brine rejection; an expensive membrane replacement and the use of strong chemicals are the most common practices to deal with these costly and environmentally unfriendly issues.
Environment; what happens to all that brine of salt from Reverse Osmosis? Brine consists of mostly water saturated with salts along with some chemicals used in the desalination process. When desalination is used inland, solutions include dilution of the brine to minimize its ecological impact before putting it back into a water reservoir, evaporating it to make rock salt, or building pipelines to carry it back to the sea. In many cases all that salt goes back into the ocean disturbing ecosystem and polluting it
Can you imagine the amount of water they would have to process to keep a LAKE in the middle of a desert?
I don't think it is a realistic idea IMHO.

I thought that was what they were attempting to do with "carbon tax" and "cap and trade"
