Desalination is the process of removing salt and other impurities from seawater to make it safe for drinking and other domestic uses. Gibraltar has several desalination plants that produce freshwater from the surrounding seawater, ensuring a constant supply of clean water for its population.
In addition to desalination, Gibraltar may also receive some freshwater from rainfall, but this is typically not sufficient to meet the territory's water needs, given its arid climate and limited land area. Therefore, desalination remains the primary method for providing freshwater to Gibraltar.
