Sea Water Desalination Plant - 4 piastre

Issued in 1974, this stamp commemorates Saudi Arabia's expanding sea water desalination program, one of the Kingdom's most important technological and infrastructure achievements. The design depicts a large coastal desalination complex with industrial installations, storage tanks, and processing facilities. In a country where freshwater resources are naturally limited, desalination became a vital means of supplying potable water to cities, industries, and communities throughout the Kingdom. During the 1970s, Saudi Arabia invested heavily in desalination technology, becoming a world leader in the production of fresh water from seawater.

By issuing this commemorative stamp, the Kingdom of Saudi Arabia highlighted the importance of water security and technological innovation in national development. The issue celebrated the successful application of modern engineering to address environmental challenges and emphasized the role of desalination in supporting economic growth, urban development, and improved living standards throughout the country.
