Zusammenfassung:	PROBLEM TO BE SOLVED: To monitor the operating situation of a small-scale pump facility at a point apart from sewage pipes. SOLUTION: A cylindrical body of a small-scale pump facility is furnished internally with a float type water level switch 1 and associate switch 2 as reserve which are to sense the water level when the pump is at a standstill, another float type water level switch 3 and associate switch 4 as reserve which are to sense the water level when the pump is in operation, and a float type water level switch 5 for sensing a high level of water surface. The results from sensing of these switches 1-5 are sent from a notification device 14 to a central confirmation device 15 via a telephone circuit 12. The central confirmation device 15 is located at a point apart from sewage pipes and registers the results from sensing given by the notification device 14.
