Some models incorporate an alarm system, such as a siren or flashing light, that activates if something goes wrong. Most septic ejector pumps designed for residential use require 110-120 to 220-240 volts of electricity to operate. Pumps that grind the solids before pumping are referred to as grinder pumps. The pumps are designed to transport solids up to a certain size, or to grind the solids into smaller pieces. Common residential models are designed to handle up to 30 gallons of effluent and waste material.

There are various sizes, horsepower and types of sump pumps to meet the demands of most applications. A check valve is added to the outlet line that prevents waste and effluent from draining back into the sump basin after it is evacuated. A tight-fitting lid seals the sump basin preventing waste or smell from escaping. As the wastewater is pumped out, the level drops and lowers the float, which deactivates the septic ejector pump.ДЄ vent attached to the pump connects to an existing vent stack or stubs up through the roof of the building to provide adequate ventilation. As wastewater fills the sump basin, a pre-set float attached to the septic injector pump activates the septic ejector pump, which pumps the wastewater out of the sump basin and into the main sewer line or septic tank. An outlet line - usually around two inches - attached to the septic ejector pump connects to the main sewer or septic line. The applicable drain lines are then graded and connected to an inlet on the side of the sump pump basin. The sump basin, a holding tank that is buried below ground, is designed to catch the waste and house the sump pump. Households with one or more bathrooms below septic or sewer line grade, require a septic ejector pump to remove unwanted waste from the structure.

A septic ejector pump, sump pump or grinder pump is a system designed to remove effluent and solid waste from a home when plumbing fixtures, such as a toilet or sink drain, are below the grade of the septic tank or sewer line.
