Introductory paragraphs: The purpose of a pump is to add energy to a fluid, i.e., the energy of the water leaving a pump (the sum of elevation potential, pressure, and kinetic energies) is higher than that of the water entering the pump. Engineers must be able to assess the performance requirements for a pump or pumping plant and determine the appropriate type, number, and sizes of pumps for an application, as well as the size and type of power units required to drive the pumps. In addition, they should be able to design the pumping plant installation, estimate the cost of operation, and supervise construction and operation of the plant.

Pumping plant installations are most often required in drainage and irrigation enterprises. Pumping plants for drainage may provide outlets for open ditches and pipe drains or lower the water table by pumping from shallow wells. In irrigation, pumps typically move water from wells and storage reservoirs into other reservoirs, irrigation canals, or pressurized pipe systems.
