International Science Community Association Research Journal of Engineering Sciences 15 1 2026 01 26 Optimizing pumped water utilization from Modified water wheel for Drip irrigation 1 7 EN Quipo June C. 1 College of Engineering, Nueva Vizcaya State University, Bayombong, Nueva Vizcaya, 3700, Philippines > Research Paper 2025 3 1 2026 01 26 A study was conducted to improve the performance of a water-wheel pump for irrigation. The modified water wheel was tested in an irrigation canal and was capable of pumping water for 300 meters using a conveyance pipe with a head of 4 meters. Results showed that the pumping capacity achieve was 4.63m3/hr, 3.14m3/hr, 1.78m3/hr, and 0.90m3/hr at conveyance pipe lengths of 10m, 100m, 200m, and 300m respectively. Additionally, the minimum pumping capacity of the water wheel was determined to be suitable for planting 0.45ha of tomatoes, 0.22ha of eggplants, and 0.45ha of peppers. The resulting net benefit was PhP147,752 per year. The economic analysis indicates that the system is financially viable for a drip irrigation setup spanning 10m to 200m.
