This study seeks to justify design parameters that enhance the efficient operation of submersible pumps in support of Sustainable Development Goals (SDGs), especially SDG number 6, 7, and 9. Laboratory experiments and flow-path modeling were combined to assess water quality, suspended solids, and energy loss in pipelines. Pump performance under varying conditions was evaluated, including wear impacts on seals and thrust bearings, using vibration diagnostics. Bypass regulation improved efficiency and reduced required head, while valve throttling increased energy loss and caused overheating at low flow. Friction loss rose due to pipe scaling and corrosion. The study shows that performance degradation occurs because of mismatches between hydraulic resistance and impeller load, and insufficient cooling under sediment-rich conditions. The findings offer guidelines for intelligent pump control and predictive maintenance. These improvements are crucial for optimizing water resource infrastructure, reducing energy consumption, and ensuring sustainable irrigation and drainage in line with global development goals.
