What does an ejector handle?

An ejector is designed to handle sewage, which consists of human waste along with water, soap, and other substances found in residential and commercial wastewater. These systems are specifically configured to transport sewage from lower elevation areas to higher elevation locations, such as when the sewage must be pumped from a basement or lower level to the municipal sewer system that is positioned at a higher elevation.

The ejector pump employs a motor-driven impeller to create centrifugal force that draws the sewage into the pump and then forces it upward through a discharge pipe. This functionality is crucial in ensuring that sewage moves efficiently out of buildings, particularly in situations where gravity alone would not suffice.

The other options, including stormwater, clear wastewater, and groundwater, relate to different systems and treatments. While ejectors can handle various types of water, their primary purpose in plumbing design is the effective movement of sewage through pressured systems, making them a vital component in managing sanitary drainage systems.
