  • Sewage effluent volume control and alarm arrangement for pressurized sewage disposal system
    Patent number: 4230578
    Abstract: Sewage effluent from a septic tank collects in a holding tank before being pumped out into a disposal field. The pump is turned on and off automatically by a control circuit which includes maximum and minimum level float switches in the holding tank, so that a predetermined volume of the effluent is discharged under pressure into the disposal field during each on-and-off cycle of the pump. A third float switch in the holding tank triggers an alarm whenever the effluent rises above a predetermined maximum level. The alarm signalling system may be silenced or tested by a manual switch.
