Abstract: A deterministic-stochastic time series model for wastewater flow rates is used in simulated real-time operation of in-line flow equalization process. To size wastewater flow equalization basins a design method is proposed that utilizes the simulation to obtain a functional relationship between performance estimates and storage capacity. When applied to the case of Ottawa’s Green Creek Pollution Control Centre, the statements of expected performance given by the proposed method indicate that the range of storage capacities delivering the highest degree of flow-smoothing is close to the volume requirements suggested by previous methods. The proposed method, however, gives probability estimates about the expected performance of the flow equalization facility.
