摘要： A system (100) for and a method of monitoring water drainage is provided. The system for monitoring water drainage comprising a sensor interface (118), a storage (120), an atmospheric precipitation unit (130) and a signal generator (140). The sensor detects whether water is present at an associated surface (112) and generates a sensor signal (111). The storage stores water drainage information that relates to the associated surface and comprises characteristics of water presence on the associated surface in cases of atmospheric precipitation. The atmospheric precipitation unit receives recent atmospheric precipitation information. The signal generator i) obtains predicted water presence data by applying the water drainage information retrieved from the storage to the atmospheric precipitation information, ii) compares the sensor signal received from the sensor with the predicted water presence data, iii) generates a warning signal (151) indicating a problem with the water drainage if in the comparison a too large deviation is detected.
