What is the main function of a sewage ejector?

The primary function of a sewage ejector is to lift sewage. This is essential in situations where the sewage needs to be moved from a lower elevation to a higher elevation, such as when a basement bathroom is installed below the level of the main sewer line. The sewage ejector works by collecting wastewater and using a pump to propel it upward into the sewer system. This mechanism ensures that sewage is effectively conveyed to the appropriate drainage or treatment facilities, thereby preventing any backups or stagnation in the plumbing system.

While there are other functions related to sewage management, such as treatment, disposal, and venting, those are not the primary role of the sewage ejector itself. The treatment of sewage is typically handled at wastewater treatment facilities, disposal refers to the final management of waste, and venting addresses air flow in the plumbing system. Therefore, the primary responsibility of the sewage ejector distinctly focuses on the lifting function to maintain effective sanitary conditions.
