The Fountains of Bellagio have been dancing for 20 years.
And in those 20 years, they've put on more than 225,000 performances. But what does it take to maintain the beloved fountains and 8.5 acre lake?
Quite a lot, actually.
A team of 30 people -- engineers, pool specialists and maintenance divers -- work to keep the fountains dancing several times a day, 365 days a year.
There are four types of water-emitting devices. Oarsmen spray water in a movable stream as high as 77 feet. Each is individually programmable and pumps water through at 140 gallons per minute. The mini-shooters, super-shooters and extreme-shooters shoot water straight up to a height of 100 feet, 240 feet and 460 feet respectively.
The Fountains of Bellagio currently have a catalog of expertly choreographed shows to songs by artists from Elvis Presley and Cher to Bruno Mars and Tiesto. The music is fed through 183 speakers which are situated along the lake's perimeter. There are 30 additional speakers solely for the bell tower bells. The speakers' output is equal to what two major concert venues would put out.
The shows happen several times a day, 365 days a year.
