Low Energy Precision Application (LEPA irrigation) is defined as: a low pressure irrigation method - details see: https://www.machineto.com/pivot-irrigation-machine-10183674

Center pivot irrigation

The center pivot system consists of one single sprayer or sprinkler pipeline of relatively large diameter, composed of high tensile galvanized light steel pipes supported above ground by towers move on wheels, long spans, steel trusses. One end of the line is connected to a pivot mechanism at the center of the command area; the entire line rotates about the pivot. The application rate of the water emitters varies from lower values near the pivot to higher ones towards the outer end by the use of small and large nozzles along the line accordingly.

The center pivot system consists of a single long irrigating pipeline attached to a central tower and moves slowly over the field in a circular pattern and irrigates the plants with sprayers, on it at frequent spacing, The central tower with a pivot mechanism and main control panel (electric) is anchored to a small concrete base at a fixed water supply point (hydrant) at the center of the field. The entire irrigating pipeline is supported above ground by “1” move on wheels, long spans, steel trusses and/or cables; the end of the pipe is over hung with a sprinkler gun. The whole system rotates slowly, around the fixed pivot, self-propelled, applying water in the form of overhead spray irrigation and covers the area in a circular pattern. An automatic alignment system keeps always the irrigating pipeline straight.
