A sewage system for handling human waste provides for comminution of excrement and other material processed therein. The system is primarily of use in a system wherein the toilets empty into sewage pipe leading to a septic field and avoids the need for frequent reaming of the sewage pipe. In this system, an electrically powered grinder of a size small enough to fit within the sewer pipe is fitted in said pipe at the outlet from the toilet. The grinder is supported in the sewer pipe and sealed in place so that all of the effluent from the toilet passes therethrough. The housing of the grinder has a supporting flange that supports it by being sealed between the bottom flange of the toilet and the sealing gasket on the floor.
