The one that began operating in 2004 on Exuma produces an average of 165,000 gallons of desalinated water daily, with the capacity of 400,000 gallons. Yes, this water is more expensive than natural well water. But wells near shorelines frequently have higher saline levels than desired.

Reverse osmosis water plants
After spending a week on Exuma in the Bahamas using nothing but reverse osmosis water got me pondering why the United States has so few of these RO plants. James City County uses one of these plants to supplement our water supply. The largest such plant in the U.S. is a new one in Carlsbad, California. And many cruisers have small scale watermakers onboard.
