This paper predicts and enhances the hydraulic problems in the Faraskour pumping station. Initially, water could not reach the first and fifth units of the operation. The main hydraulic problem of the suction basin of the new pump station is the sharp rotation of the suction guide from the sharp rotation of the quay station, and that caused the continuous discontinuation of the first and fifth units due to the lack of regular water entering the unit. A numerical simulation was conducted to investigate the hydraulic stability of the station. Computational fluid dynamic (CFD) is used to simulate the flow conditions at different working pumping units to predict the hydraulic problem at the suction side. The results indicate that the geometry of the intake is proper for running five parallel flow pumps with the designed flow rate and use guide walls with a curvature length of 6 m and width of 0.5 m for each pump.
