Propagation Non Linéaire

A number of reports on simulations of real-time control of combined sewer system runoff have been published. Most of the control strategies suggested use linear models to calculate discharge routing. We used a nonlinear model for discharge routing and some of our findings differ from those obtained in earlier studies. In particular, it appears that the prediction horizon used for control optimization could be favourably shorter than the time of system flow-through. Key words: combined sewer system overflow, real-time control, nonlinear programming, discharge propagation. [Journal translation]

Combined Sewer System

Emschergenossenschaft and Lippeverband have developed a method to use radar-measured precipitation as an input for a real-time control of a combined sewer system containing several overflow structures. Two real-time control strategies have been developed and tested, one is solely volume-based, the other is volume and pollution-based. The system has been implemented in a pilot study in Gelsenkirchen, Germany. During the project the system was optimised and is now in constant operation. It was found, that the volume of combined sewage overflow could be reduced by 5 per cent per year. This was also found in simulations carried out in similar catchment areas. Most of the potential of improvement can already be achieved by local pollution-based control strategies.

Set Up

The research project ‘Real Time Control of a Combined Sewer System by Radar estimates of Precipitation’ seeks to improve the water quality of a stream by reducing quantitative and qualitative discharges of combined sewage overflow (CSO). The complex monitoring and simulation system that has been set up for control purposes is described. Two advanced real time control (ARTC) strategies have been developed. First a pollution based real time control (PBRTC) strategy, and second a water quality based real time control (WQBRTC) strategy. The PBRTC strategy is already implemented, the WQBRTC strategy will be implemented during the course of the project. For the PBRTC an off-line analysis is presented to show the effectiveness of the strategy.

The City

Several simple quality–discharge models (concentration of suspended matter) are proposed for the atomatic real-time control of combined sewer system overflows. These models are calibrated and verified with data supplied by the City of Québec. They can be useful in setting up a control system which takes into account quality without using real-time measures, since their forecasting capability is interesting even if not perfect. Key words: urban runoff, combined sewer system, quality–discharge model. [Journal translation]

The application of real-time control to the sewer system in a district of Copenhagen is described. It enables the storage capacity of the sewer system to be better utilised, thus minimizing combined sewer overflow pollution.
