Dubai Fountain is the center piece of the Downtown Burj Khalifa. Emaar, the developer of Burj Khalifa, and Downtown Burj Khalifa had announced the Dubai fountains in June 2008, at the expected cost of AED 800 million or USD 218 million, which is the total cost of the Fountain's lake, the fountain, and its filtration system. The Dubai fountain is one of the world's tallest fountains, surpassing the Fountains of Bellagio at Las Vegas. The Dubai fountains is 275 m (902.2 ft), which is more than the length of two football fields. It is 25 % larger than the Fountains of Bellagio at Las Vegas. The Dubai Fountains can be seen from over 20 mi (32.2 km) away up or horizontally if you have a clear line of sight. The fountains can shoot to the maximum height of 150 m (492.1 ft), which is equivalent to a 40-storey building or high enough to wash the windows a fifth of the way up the Burj Khalifa.
