The purpose of this study was to evaluate retention time distribution and flow line clearwell in water works using computational fluid dynamics. With the finite volume method using the computational fluid dynamics (CFD), a technical diagnosis of clearwell in the water purification process was performed using an unstructured hexahedral grid system. A vector simulation showed stagnation for over 400 seconds at the circulation areas. Where clearwell have an average flow rate, a vector analysis at a height of 1.0 m showed a normal flow downstream. However, some sections of the L-shaped rear section at the left bottom of Clearwell No. 1 partially had the vortex that could cause stagnation. An analysis of flow speed contour line showed that a row of dividers in clearwell partially served as partitions. The results of the analysis can be used as basic data for the creation of alternatives such as the installation of supplementary training walls within clearwell.
