Small sewage ejectors are for homes and commercial applications where toilet usage and wastewater loads are modest.Ī typical home sewage grinder pump uses a 1/3 to two horsepower electric motor which powers a grinder mechanism that grinds the waste, and an actual sewage waste pump which moves the ground sewage/wastewater mixture up a riser pipe to its destination: the building main sewer drain, where the wastewater is carried to a septic tank or to a community sewer line. Septic grinders are intended for use at residential or small commercial locations.īecause the waste is ground and pumped under pressure, these pumps can lift high distances, say from a basement floor even to a street sewer which may be uphill from the home, or to a high pressure sewer main that may be located some distance away.įor example, we inspected a summer camp community which used this force-main sewer system to move waste from buildings across a site covering several acres to a common septic system. The building sewer drain then carries this mixture by gravity (a gravity main system) or by pump pressure (a forced main) to its destination at a septic tank and drainfield system or to a municipal sewer. Sewage or Septic Grinder pumps grind the solid waste entering the system, then pump it to the building drain. (Sketch is from the Environment One Low Pressure Sewer Systems Grinder Pump catalog.)

At left the sewage grinder pump parts include: The pump shown at the top of this page is a sewage grinder pump which grinds the waste and pumps the solid/liquid measure to the building main drain. When a float inside the reservoir indicates that the sewage level has reached a high level in the reservoir, the float turns on the grinder pump which grinds and pumps away the waste. The sewage grinder pump is housed in a plastic or steel reservoir which receives waste from the bathroom or other plumbing fixtures it serves.
