By transmitting weather data from Citymonitor directly to the Dornbirn-Schwarzach wastewater treatment plant (ARA), overloading the plant in the event of heavy rain can be prevented by taking targeted and timely measures.
In Dornbirn, weather stations were placed at topographically and meteorologically interesting locations in the city's water catchment area. The selected locations have a significant influence on the performance of the sewage network, especially in the event of heavy rain. The sensors measure various environmental data, such as current precipitation, and transmit this to Citymonitor in real time. LoRaWAN — a particularly efficient, license-free wireless network that is characterized by a long range and minimal power consumption — is used for transmission. In the Citymonitor platform, the data is processed and visualized historically and geographically.

More efficient control of ARA through real-time information
Through the undelayed and automated transmission of data via the Citymonitor platform, the available information can be evaluated directly at the relevant points and measures can be initiated to improve control of the entire system. The real-time information provides information on how much water is currently expected in the plant. In combination with knowledge of which quantities can be processed by the plant, appropriate actions can be taken to counteract overloads and floods.
Automated reports, a basic function of Citymonitor, can be created for various data streams. Here, the data is forwarded directly to the ARA.
Internal analyses and citizen information
However, the collected data is also used internally by the City of Dornbirn for planning and evaluation. It is also possible to provide the data on “Dornbirn Live” - the portal for citizen information - to give interested persons a detailed insight into the current environmental data. In special cases, such as heavy rain or black ice, residents can even be informed at an early stage via push notifications.
