The water plant uses reverse osmosis to desalinate sea water. It must also heat the sea water, as it is about 28 F (4 degrees Fahrenheit below freezing, which is possible due to salinity). There are two RO (reverse osmosis) filter set ups. They are just enough
to provide water for McMurdo at peak capacity. Each can process about 40,000 gallons of water per 24 hours, for a total capacity of 80,000 gallons for up to 1200 people - about 67 gallons per person per day.
