Performance Evaluation of a Sustainable Urban Drainage System for Highly Urbanized Areas 1: Toronto Metropolitan University, Canada; 2: University of Sheffield, UK Highly urbanized areas pose the most significant challenge for stormwater management due to limited opportunities for implementing sustainable urban drainage systems (SUDS). A SUDS termed Toronto Exfiltration System (TES) was developed to utilize the pore space within the storm sewer trench for stormwater retention and detention. A full-scale model of TES (46m x 2.3m x 1.7 m) was built and used to evaluate the associated runoff control performance. Both steady-state and unsteady-state hydrologic performances were tested using the model (with underlying sandy and clay soil environments). For the 12 m section of TES with clay underlying soil, the steady-state inflows (3 and 10 L/s) were reduced by 47% and 56%, respectively, and the unsteady-state inflow peak flows and volume (5-year and 10-year hydrographs) were reduced about 94% and 45%. For the 12 m section of TES with sandy underlying soil, the steady-state inflows (5, 10, and 15 L/s) were reduced by 71%, 92%, and 83%, respectively, and the unsteady-state inflow peak flows and volume (10-year abd 50-year hydrographs) were decreased about 98% and 50% respectively. Results indicate that TES can be an effective SUDS for highlighted urbanized areas. | |
