Introduction
The pumping plant generally accounts for a substantial
portion of the initial cost and a major portion of the
annual operating cost associated with a sprinkler
irrigation system. Over 90% of the energy used by an
irrigation system is used by the pump. The selection
of the pumping plant, then, has a significant influence
on the economics of irrigating. Careful planning and
selection of this essential component helps to ensure
both the adequacy, efficiency, and viability of the
entire irrigation system. An irrigation pumping plant
consists of a power unit, a pump, and all required
accessories such as piping, valves, gauges, safety
equipment, and mounting platforms. This bulletin
deals with the two primary components: the power
unit and the pump.
