US Patent 9989397 Water management sensing

In some implementations, a system obtains activity data for a sump pump associated with a property where the obtained activity data indicates a present operational status of the sump pump. The system obtains water level data associated with the property where the water level data indicates a level of water within the property, determines that the activity data indicates that the sump pump is operating and that the water level within the property satisfies a water level risk threshold, and, in response to the determination that the activity data indicates that the sump pump is operating and that the water level within the property satisfies a water level risk threshold, provides a notification that the property is at risk of suffering water damage.
