1. A system for detecting and utilizing rise rates when implementing control of a sump pump, the system comprising: a sump pump configured to pump water out of a sump basin; a sensor coupled to the sump basin; a sump pump control system coupled to the sump pump and the sensor, wherein the sump pump control system is configured to: detect, via the sensor, a first rise rate of water in the sump basin during a first time period before an activation of the sump pump; detect, via the sensor, a second rise rate of the water in the sump basin during a second time period after a deactivation of the sump pump; detect, based on a comparison of the first rise rate to the second rise rate, a backflow condition indicating whether or not water is backflowing into the sump basin; and implement control based on the detected backflow condition, wherein the control includes at least generating a signal indicating the backflow condition in the sump basin.
