Remote control system for the operation of 65 WWTPs

The present report discusses the monitoring system for approximately 340 facilities for water management of the Emschergenossenschaft and Lippeverband. It is based on the operation control system of the wastewater treatment plants (currently 61) and the pumping stations of the Lippeverband, which has been created since 1985. For the near future, the integration of the plants of the Emschergenossenschaft including storm-water tanks is scheduled. The current connection ratios of the WWTPs which are to be monitored vary between 500 and 1,940,000 Population Equivalents. The data recorded at each plant are transmitted to the allocated catchment area centre and then to the district centres. The encompassing monitoring centre serves the integrated control of all plants. The comprehensive remote control is managed through the presentation of relevant plant-type-specific system parameters. The investment costs of approximately 33,000 Euros/plant and annual costs of 9,400 Euros/plant stand against a considerable increase of the operation safety and the reduction of manpower.
