The aim of this research paper is to design a drip irrigation system for a Pineapple orchard in the Federal University of Technology Owerri school farm. This work takes into account the preliminary studies of the study area (general relief, topography and soil nature), water quality and quantity assessment (water sample collection, testing and analysis), soil and field analysis (moisture content test, infiltration tests and grain-size analysis) and climatic influence on the area to make resolute conclusions on the parameters required for the design of the drip irrigation system. With reference to the peak consumptive use of pineapple (1.928mm/day) and peak potential evapotranspiration (4.794mm/day) obtained from application of empirical formulas; the drip irrigation system designed comprises of 48 laterals (Inside Diameter of 10mm, 1104 emitters, Discharge of 0.012L/S, and Friction Loss of 13.44m), 1 submain(Inside Diameter of 28mm, Discharge of 0.56L/S and Friction Loss of 3.65m) and 1 mainline (Inside Diameter of 42mm, Discharge of 0.57L/S and Friction Loss of 0.02m) with an actual emission uniformity of 85%.
