Abstract of the Disclosure The macerator-sterilizer sewage treatment system, that is useful in an overall toilet system to collect, treat and discharge toilet wastes, comprises: macerator/transfer pump means to receive flushed human waste from toilets and urinals a collection tank connected by conduit means to the outlet of the pump means; a sterilization tank connected by power-operated rat d valved transfer means and transfer pump means to the collection tank; heater means in the sterilization tanks; power-operated valved discharge means connected to an outlet of the sterilization tank; and electrical means to control the operation of the macerator/transfer pump means, of the transfer pump means between the collection tank and the sterilization tank, of the heater means, of the power-operated valved dis- charge means connected to the outlet of the sterilization tank and of the power-operated valved transfer means. The electri- cal control means initiates in response to a flushing operation the operation of the macerator/transfer pump means for a predetermined peroid of time, initiates in response to a preetermined accumulation of the flushed human waste in the collection tank the operation of the transfer pump means for a predetermined time and opens the valve of the valved transfer means for a predetermined time to transfer waste from the col- lection tank to the sterilization tank, controls the operation of the heater means, and then after a preset time opens the valve of the valved discharge mean for a predetermined time. The electrical control means also prevents the operation of the macerator/transfer pump means during an initial portion of the transfer of waste from the collection tank to the sterilization tank even though flushed waste is provided to the macerator/ transfer pump means and prevents the operation of the transfer pump means and the opening of the valve of the valved transfer means that transfer flushed waste from the collection tank to the sterilization tank until the waste is sterilized in and discharged from the sterilization tank.
