Emscher demo case: Real-time-control (RTC) of sewer network ready for implementation

The two demonstration technologies in the Emscher case focus on water quality issues. Aim is to decrease the amount and improve the quality of combined sewer overflow (CSO) into recipient rivers.

Five CSO facilities in the upper Emscher river section are now ready for implementation of the RTC system ADESBA. The function of the ADESBA communication software is the optimal utilization of the entire available underground storage volume. The final aim is to reduce pollutant input into streams by reducing the overflow frequency and volume from CSOs into streams.

To fulfil the preconditions, all facilities had to be equipped with online communication systems and their internal programming had to be adapted. One of the facilities required an additional outflow regulator. Simulations based on historical data and modelled data were run. Furthermore, safety functions were incorporated.

After a testing phase, the actual control operation will be initiated. During the entire pilot phase, the system’s performance will be monitored. Based on these findings, predictions on the effects on the ecosystem and its services will be made. Milestone 23 of the DESSIN project has been reached with these actions.
