Lake Las Vegas water intake pump (USA)

Las Vegas, the largest city in the state of Nevada, is also known as the city in the desert. Its domestic water is supplied from the Hoover Dam (Lake Mead), located 48 kilometers away. The low water level at the Hoover Dam (Approx. 150 ft lower since 2000) has become a major social problem in the USA.

Three intake pumping stations (IPS1 to IPS3) are in operation for water intake from the dam, but each additional pumping station requires to intake water from a much deeper location, calling for the specialized pumps that demand advanced technology. EBARA delivered pumps to two pumping stations, IPS2 and IPS3. The IPS2 uses a vertical-shaft, mixed-flow, multi-stage pump. Designed to pump water from 67 m below the surface of the lake when it is full, and the pump, with a total underfloor length of 88 m, is the longest vertical-shaft mixed-flow pump the Infrastructure Company has supplied.

The IPS3 uses a submersible motor pump with a world-leading output of 3351 HP (2500 kW). Designed to pump water from 100 m below the surface of the lake when it is full, the submersible pump installed at a location about 140 m above ground level and the ground pumps water to the surface through vertical pipes. This pump, with a unique double-suction, single-stage structure for the impeller, increases rotating speed to achieve superior suction and a high pump head. EBARA has delivered a number of large water supply pumps to the Nevada State Water Authority, which have been highly valued for the usage in lake water intake application.
