Abstract: The mechanism of flow in settling basin is so complicated that it is very difficult to establish a general regression model to accurately estimate the sediment removal efficiency. No general relationship is available which can be used for estimation of sediment removal efficiency of settling basin under flushing condition as well as without flushing condition. Even in the absence of flushing, considerable differences exist in efficiencies given by different methods. The present study aims to re-analyze the databases to develop a general regression model for the determination of sediment removal efficiency of settling basin. The equation for sediment removal efficiency of settling basin given by Ranga Raju et al. (1999) has been checked and it was observed that the Ranga Raju et al. (1999) predictor does not give the reasonable estimate of sediment removal efficiency of settling basin. Therefore, the data have been re-analyzed and a new equation is developed which is recommended in order to predict the sediment removal efficiency of settling basin. The qualitative performance of present predictor indicated that it has lowest 𝑨𝑨𝑫,𝑹𝑴𝑺𝑬, 𝑨𝑷𝑬 and highest 𝑹 as compared to Ranga Raju et al. (1999) predictor.
