Performance Analysis of the Maclean Avenue Detention Tank City of Toronto Lijing Xu1 and Barry J. Adams2* 1 XCG Consultants, 2620 Bristol Circle, #300, Oakville, Ontario, Canada, L6H6Z7 2Department of Civil Engineering, University of Toronto, Toronto, Ontario, Canada,M5S1A4 e-mail: adams@ecf.utoront.ca ABSTRACT The Maclean Avenue detention tank was constructed by the City of Toronto to decrease the frequency of beach closing caused by directly discharged stormwater and CSOs in the Eastern Beaches area of the City. The purpose of this study is to evaluate the performance of the detention tank for wet weather flow pollution control through a 5-year field monitoring program and to improve the engineering understanding of such stormwater control facilities. Tank performance measures on runoff quantity control are obtained from the analysis of 220 runoff events recorded in those five years, and the tank performance for pollution control is subsequently calculated from the quantity control analysis results and influent and effluent EMCs. According to the specific operational features of the Maclean tank and the principles of analytical probabilistic models, models are derived for both runoff quantity control and quality control analysis of the tank. Field monitoring data are used to calibrate and validate the derived models. A comparison among the observed results, predicted results from QQS continuous simulations and the derived analytical probabilistic models is made and conclusions are drawn on the current performance of the tank and on the utility of monitoring and modeling results.
