Automated system for control of sewage pump station of water draining system has switch block, control block and inspection sensor, switch block is installed with possibility of its input connection to power source, and outputs with possibility of connection to electric motors of pump units, control block is connected to switch block, output of sensor of water level is connected to respective input of control block. The system is arranged as control cabinet with frequency transformer with power and control inputs and outputs, device for smooth start of electric motor of electric motor of pump unit and indicator of water level control with back coupling. Frequency transformer and device for smooth start are installed with possibility of connection to power source. Power input of frequency transformer and unit of smooth start are connected to input of switch block. Control output of frequency converter is connected to input of control circuit. Output of control circuit and output of sensor of water level control are connected to control inputs of frequency transformer, respectively.
