A pumping pant which is more compact in size and has reduced total costs required for construction work of the pumping plant and associated civil engineering works and has a shorter term of the entire construction work includes a pump building which is constructed in its entirely as an island-type building in the form of an island in a suction pond serving as a pump well, whereby the need to refill earth and sand around the pump building is eliminated, and the cost of associated civil engineering works is reduced. Water is sucked from all sidewalls of the pump building, and pumps are arranged within the pump building in at least two rows, resulting in a reduced length of the building. Horizontal portions of a suction pipe and a delivery pipe are extended from the pump in the same direction to reduce a width of the building and to make it compact. A total cost required for the construction of the pump building and associated civil engineering works can be thus reduced. Two ceiling cranes are installed in a one-to-one relationship to the pumps in two rows, enabling the pumps, etc., in both rows to be installed at the same time. This also contributes to cutting down a term of the entire construction work.
