The development and implementation of a real-time control strategy for the sewer system of the Vienna city was scheduled for completion in 2004, but the implementation of the first phase was finished in early 2005. The 4.5 years project comprises all planning and implemen-tation phases. A measuring system including 25 rainfall, 40 flow and 20 water level measurements was im-plemented to serve for model calibration and real-time control purposes. The detailed network of approx. 53,000 pipes was reduced to a coarse network of approx. 2,600 pipes. The land use data were derived from aerial photographs. Rainfall runoff simulations were used to examine the system behavior and to develop the rule base. In a simulated real-time control the rule base was improved, while further improvements will be done on-line with a self-learning sys-tem. A forecasting model using rainfall radar data will additionally influence the control deci-sions. The simulated results for the first phase of implementation, demonstrating the benefits of RTC for the Vienna sewer system are explained. The comparison between measured and simulated real-time control are not presented in the paper but in the oral presentation. The ex-perience gained from implementation is discussed.
