Worlds Tallest Fountain

Worlds Tallest Fountain

King Fahad’s Fountain, also known as the Jeddah Fountain, is the Worlds Tallest Fountain. Located in the coast of Jeddah, west coast of Kingdom of Saudi Arabia. The fountain jets water 1,024 feet (312 m) above the Red Sea. It was donated to the city of Jeddah by King Fahd, hence its name. The fountain is visible throughout the entire vicinity of Jeddah. The water it ejects can reach a speed of 375 kilometres (233 mi) per hour and its airborne mass can exceed 18 tons.  The fountain uses saltwater taken from the Red Sea instead of freshwater. It uses over 500 spotlights to illuminate the fountain at night.

The first construction of the fountain was developed between 1980 and 1983, after the style of Lake Geneva’s freshwater fountain, which reaches 460 feet into the air at speeds of approximately 124 miles per hour. This scale was found to be insufficiently impressive for planners.

The fountain as it stands today began operating in 1985, and has been running without any significant difficulties for over twenty years. A comprehensive maintenance system includes daily, weekly, bi-weekly, monthly, half-yearly and annual inspections and maintenance operations.

Because Jeddah’s Fountain operates using sea water running at unusually high speeds; corrosion and abrasion were key challenges to the builders, SETE Technical Services Latsis Group. The intakes for the pumps are in a special pit that is continually pumped dry and treated annually with anti-fouling paint that prevents growth of marine life. The water is passed through a series of screens before it reaches the pumps, filtering out soil, sand, and organic matter. The pipes and pump systems are isometrically designed and made of special stainless steel.

Water exits the pumps via a 350 meter high-pressure output line constructed with steadily decreasing diameters towards the nozzles. The nozzles are constructed of a specially designed alloy which can withstand a constant pressure of forty-two bar (over 609 pounds per square inch). The five hundred high-intensity spotlights that illuminate the fountain also had to be specially designed to withstand the constant barrage of thousands of tons of water an hour falling from several hundred feet.

The spots are mounted on special islands. A cathodic system was installed in 1987 to protect the pipelines from the corrosive effects of the falling seawater, consisting of fifty-seven anodes and twenty-nine reference electrodes at seventeen points along the system.
