The Fountains of Bellagio is a vast, choreographed water feature with performances set to light and music. The performances take place in front of the Bellagio hotel on the Las Vegas Strip and are visible from numerous vantage points, both from the street and neighbouring structures.
The show takes place every 30 minutes in the afternoons and early evenings, and every 15 minutes from 8 p.m. to midnight. Before a water show starts, the nozzles break the water surface and the lights illuminating the hotel tower turn to a purple hue (usually), or red-white-and-blue for certain music. Shows may be cancelled without warning because of wind, although shows usually run with less power in face of wind. A single show may be skipped to avoid interference with a planned event. The fountain display is choreographed to various pieces of music, including songs by Andrea Bocelli, Frank Sinatra, and Gene Kelly. The fountains are set in a 9-acre (3.6 ha) man made lake.
Contrary to urban myth, the lake is not filled with treatedgreywater from the hotel. The lake is actually serviced by a freshwater well that was drilled decades prior to irrigate a golf course that previously existed on the site. The fountains actually use less water than irrigating the golf course did. They incorporate a network of pipes with more than 1,200 nozzles that make it possible to stage fountain displays coordinated with more than 4,500 lights. It is estimated that the fountains cost $75 million to build. The fountains were created by WET, a design firm specializing in inventive fountains and architectural water features.
