The lighting system is energy efficient because the lights are not on at full intensity at all times. The use of solid-state dimmers eliminates the need for frequent maintenance. Safety features include an automatic shutoff activated by the water level dropping below the surface of any light fixture or by a ground current rising above 5 milliamps; thus, any danger of shock is removed. Recirculating pumps ensure water conservation, and fresh water is added occasionally to replace any losses. The mechanical equipment for operating the fountains is located directly under the main fountain. The water is circulated by pumps, passes by gravity through a 24-inch cast-iron pipe to the lower fountains, and then flows to a concrete 30,000-gallon surge tank under the section of the terrace containing the bubbler fountains. The water from this tank is returned to the circulating pumps. Of the three circulating pumps, two have a capacity of 3,000 gallons per minute; the other can pump 1,650 gallons per minute. It is possible for all pumps to discharge against a 40-foot head. The main fountain is fabricated of Minnesota Pink granite, with a basin of Minnesota Green granite. The piers and other granite elements facing the Russell Senate Office Building terrace are made of Mount Airy granite, which blends visually with its surroundings
