Much ado is being made about the current drought in California, and it is a serious problem that does require citizens, government, and society as a whole to rise to the occasion in order to mitigate what could turn into a disaster. However, the reality is that water issues have plagued California since its inception as a state in the U.S.
So while it makes a lot of sense to cut back wherever possible, it is also imperative that we find ways to expand the water supply. A reverse osmosis water filter system, which rids water of contaminants at the molecular and ionic levels through membrane filtration, is a great option for doing that. Reverse osmosis, then, is a relatively new solution to a long standing problem.
