What mechanism is used by sewage ejectors to discharge waste to a higher level?

The correct mechanism used by sewage ejectors to discharge waste to a higher level is pumps. Sewage ejector pumps are specifically designed to move sewage and wastewater from lower levels, such as basements or below-grade installations, to a higher elevation. The pump creates a pressure differential that allows the waste to flow upward through the discharge pipe, overcoming gravitational forces that would normally prevent the waste from moving to a higher point.

Pumps in sewage ejector systems are typically submersible and equipped with a float switch to activate the pump when the sewage level rises, ensuring that waste is moved efficiently and preventing backups. This mechanism is essential in settings where gravity alone cannot facilitate the necessary movement of waste, such as in homes with lower plumbing fixtures, ensuring proper sanitation and drainage.
