The municipality of Warth expanded the wastewater treatment plant due to the increasing number of overnight stays and increasing day tourism from 5000 to 8600 population equivalents. Due to the limited space, the general planner IBMR integrated the AnoxKaldnes - Veolia floating bed process into the existing system and thus implemented it for the first time in Austria on a municipal wastewater treatment plant.

Siemens Austria supplied the central cabling and control technology including the integration of control cabinets for sludge thickener, sludge dewatering and gas utilization for sludge digestion.   - A SIMATIC S7-1500 CPU 1511-1PN, expanded via SIMATIC ET200MP, is used as the central control unit in the control room. A WinCC-OA process control system takes over the system visualization. - Decentralized (PROFINET), 10 SINAMICS G120 CU240E-2 PN frequency converters ensure the speed control of pumps, positive displacement blowers and agitators. - The Siemens product range included SITRANS process measurement technology for flow, level and pressure, as well as the SIRIUS 3RA61 compact starter - in order to do consider the limited space available.    - The specially developed energy management of the system with network monitoring from the SENTRON PAC series should also be emphasized.    - Connection of external controls with Modbus-TCP
