'the reservoir'),[1] is a 61-meters tall conical-shaped cylindrical water tower and a prominent cultural landmark in the al-Futah neighborhood of Riyadh, Saudi Arabia.

[2] Designed by Swedish architect Sune Lindström and modeled after the Svampen water tower in Örebro, Sweden, it was the tallest structure in the country at the time of its inauguration in 1971 and is today located within the precincts of al-Watan Park in the King Abdulaziz Historical Center.

The then Saudi government led by King Faisal tasked the agriculture ministry to come up with a solution by constructing a water tower.

The ministry later gave the project to a Swedish architect Sune Lindström in 1969 who worked for the now defunct Stockholm-based Vattenbyggnadsbyrån (VBB) engineering company (later acquired by Sweco in 1997)[9][10][11] to develop and implement a plan for a modern water-supply system for Riyadh.

The ministry chose the site upon the ruins of a demolished casino[12][13][14] located in close proximity of the Murabba Palace compound for the construction of the water tower to cater the needs of neighborhoods in the vicinity like al-Malazz, Manfuhah and Shumaisi.
