By definition, a water maker is a device used to obtain drinking water from seawater. The process to remove salt from water is called reverse osmosis. Water makers remove salt and other contaminants from seawater and brackish water. As a result, they produce a continuous desalinated seawater supply that is safe to drink

Not only do reverse osmosis systems solve the dilemma of making saltwater freshwater, but they are very convenient. These devices can be quite valuable to have on board because they reduce the need for large water tanks for a long passage.

Cruisers can produce 20 or 30 gallons of desalinated water per hour with the right setup. This changes everything! You can now enjoy daily showers, a freshwater deck, gear wash-downs at anchor, and freshwater flushing heads. The solution to how to make saltwater drinkable used to be enjoyed by the mega-yacht crowd only. It is now available to the average cruiser.

The Steps for Salt Water To Become Freshwater

There are five steps in making saltwater good to drink:

  1. Pre-filtration: This step removes larger particles and debris from the seawater.
  2. High-pressure pump: A pump pushes the seawater through a semipermeable membrane, leaving pure freshwater behind.
  3. Semipermeable membrane: Then, the semipermeable membrane separates saltwater into fresh drinking water and concentrated brine.
  4. Post-filtration: The polishing filter removes any remaining impurities, producing a clean water supply.
  5. Storage: The treated water is then stored in a tank ready for use.
