Las Vegas, the largest city in the US state of Nevada, is also known as the "city in the desert," and its drinking water comes from the Hoover Dam reservoir (Lake Mead), 48km away. The drop in the water level of the Hoover Dam (about 150 ft since 2000) has become a major social issue in the United States.
Lake Las Vegas water intake pump (USA)
The world's largest pumps help protect the lives of the city of Las Vegas.
Three intake pumping stations (IPS1 to IPS3) are in operation to draw water from the dam, but each time a pumping station is added, it is necessary to draw water from deeper positions, necessitating the use of specialized pumps that require advanced technology. Ebara delivered pumps to two pumping stations, IPS2 and IPS3. The IPS2 uses a vertical shaft mixed flow multi-stage pump. It is designed to pump water 67m below the lake surface when it is full, and with a total length of 88m below the floor, it is the longest vertical shaft mixed flow pump delivered by the Infrastructure Company.
IPS3 uses a submersible motor pump with an output of 3351HP (2500kW), one of the largest in the world. It is designed to pump water from 100m below the lake level when it is full. The submersible motor pump is installed approximately 140m above ground and pumps water to the surface via a vertical pipe. This pump uses a unique method of designing the impeller with a double-suction single-stage structure, which allows for increased rotational speed and achieves high absorption performance and high head. Ebara has already delivered many large water pumps to the Nevada Water Department, and has earned a high reputation for this lake water intake application.
