Abstract

Veolia has developed an optimization platform for the operation of sewer networks (POSTEVENT) and drinking water networks (OPTIM’HYDRO). This platform couples a genetic algorithm NSGA-II with hydraulic network simulation tools (INFOWORKS CS and EPANET). The challenge is to optimize the design and operation of networks according to given objectives and constraints, by changing asset control parameters. This article deals with optimization challenges raised and developed off-line support tools. It ends with a case study on a French drinking water network consisting in upscale set points for pumping stations to optimize the procurement management of water and reduce the energy costs.
