1. It starts with seawater used for cooling the Encina Power Station.
   
   
2. The seawater is piped through a series of filters to remove microscopic impurities.
   
   
3. Chemicals are added for further purification and the water is sent through a reverse osmosis (RO) system, a series of filtration membranes that removes the salt and any remaining impurities.
   
   
4. One of every two gallons of processed seawater becomes ultra high quality fresh water.
   
   
5. The other gallon is used to carry the salts removed in the RO process to the seawater discharged from the power plant as it returns to the ocean.
