Which type of sewage lift station houses the pumps and motors in a compartment separate from the one that receives wastewater?

The type of sewage lift station that houses the pumps and motors in a compartment separate from the one receiving the wastewater is known as a dry well. This design is advantageous because it keeps the mechanical components, such as pumps and motors, protected from the contaminants and corrosive environment of wastewater. By doing so, it reduces maintenance needs and enhances the operational efficiency and longevity of the equipment.

In contrast, a wet well contains both the wastewater and the pumps in the same compartment, which can expose the mechanical components to wastewater and potential clogging issues. The dry pit setup allows for easier access to equipment for maintenance and can improve the reliability of the system, as the pumps are not submerged in wastewater.
