The ABC facility is a packaging area at PT XYZ that plans to construct a pipeline to transport wastewater to the wastewater treatment plant (WWTP). Several factors must be considered in the design, including flow characteristics, pipe diameter, pressure head, and pump selection. The proposed pipeline is designed for a flow rate of 0.0015 m³/s using a 1.5-inch diameter pipe, resulting in a flow velocity of 1.32 m/s. Computational Fluid Dynamics (CFD) was employed to analyze flow behavior within the pipeline by integrating theoretical principles and numerical simulation. The simulation was conducted using the student version of SolidWorks to identify flow phenomena and evaluate the hydraulic performance of the proposed system. The results indicate that the flow within the pipeline exhibits turbulent characteristics, with a turbulence intensity of 1.87%. This turbulence intensity confirms the presence of turbulence in the pipeline connecting the ABC facility and the WWTP, indicating transitional flow behavior under the simulated operating conditions. The analysis also determined a pressure head of 42.87 m. Based on the calculated hydraulic requirements, the pump power capacity required to transfer wastewater from the ABC facility to the WWTP is approximately 3.92 kW. Considering the simulated flow conditions, pressure head, required capacity, safety factors, and pump efficiency, the EBARA GSD2 32-200.1 centrifugal pump with a 202 mm impeller diameter was identified as a suitable option. The selected pump can accommodate flow rates ranging from 4 to 37 m³/h and pressure heads of up to 52 m, with compatible motor capacities ranging from 2.5 to 7.5 kW. These results provide a technical basis for pipeline and pump selection to support reliable wastewater transfer from the ABC facility to WWTP
