Efficient integrated model predictive control of urban drainage systems using simplified conceptual quality models

Integrated control of urban drainage systems considering urban drainage networks (UDN), wastewater treatment plants (WWTP) and the receiving environment seeks to minimize the impact of combined sewer overflow (CSO) to the receiving environment during wet weather. This paper will show first results of the integrated control of UDN and WWTP, obtained by LIFE-EFFIDRAIN, which is a collaborative project between academia and industry in Barcelona (Spain) and Bordeaux (France). Model predictive control (MPC) is applied for strategy optimization using conceptual hydraulic and quality variables, where the total suspended solid (TSS) concentration is selected as a representive of water quality. SWMM5 integrated with a lumped conceptual model of TSS (SWMM-TSS) is applied as virtual reality. The Perinot sewer network from Bordeaux is used as a case study for functional demonstration.Peer ReviewedPostprint (author's final draft
