Abstract: An aspect of the invention relates to a method for verifying the plausibility of sensor information sensed by a sensor device associated with a plant process, in particular a water treatment process and/or a wastewater treatment process, wherein the sensor information relates to the plant process, the method comprising: receiving (S100), by a control unit, the sensor information; performing (S110), by the control unit, a verification model, the verification model determining an expected sensor information which the sensor device shall provide, wherein the verification model determines the expected sensor information based on at least one other information related to the plant process and having a relationship to the sensor information; comparing the expected sensor information with the received sensor information; and upon determining (S120) that the sensor information deviates from the expected sensor information, outputting (S130), by the control unit, a verification signal.
