As I’ve said before, we’re not running out of water–just running out of cheap water. 

In Florida, the drought combined with population growth is putting a strain on the water supply from existing sources. 

Typically, well water is the least expensive to treat, and it’s the preferred source for communities where it’s available. Fresh surface waters, such as lakes and some rivers line up next on the cost scale.  And when the water is brackish or salty the price starts to soar.

The water war pitting north Florida against central Florida is just a result of everyone vying for the lowest cost alternative.  But since this debate has been in the news, I’ve heard several people say that using sea water would be the best bet.

There’s plenty of it–that’s true.  But the cost of treatment is astronomical.  And there’s a couple other things to consider along with the rising water bill. 

The process for treating sea water uses huge amounts of energy.  Not good if we’re all supposed to be watching our carbon footprints.

And when you take salt out of the water it has to go somewhere.  The concentrated brine solution is considered a pollutant.  So finding a discharge location can be a challenge.

Just something to think about before everyone jumps on the sea water bandwagon.
