Fountain Hills - Arizona -The eponymous fountain was built in 1970 by Robert P. McCulloch, the year before the reconstruction of the London Bridge in Lake Havasu City, another of McCulloch's projects. The fountain sprays water for about 15 minutes every hour. The plume rises from a concrete water-lily sculpture in the center of a large man-made lake. The fountain, driven by three 600 horsepower (450 kW) turbine pumps, sprays water at a rate of 7000 gallons per minute though an 18-inch nozzle. With all three pumps and under ideal conditions, the fountain reaches 560 feet (170 m) in height[4], though in normal operation only two of the pumps are used, with a fountain height of around 300 feet (91 m) feet. When built, it was the world's tallest fountain and held that record for over a decade. [edit]
