What is the main function of pumps in a lift station?

The primary function of pumps in a lift station is to transport wastewater to higher elevations for further conveyance. In wastewater collection systems, lift stations are necessary when gravity alone cannot move wastewater to a treatment facility due to topographical constraints. Pumps are utilized to move wastewater from lower to higher points, ensuring that it can be effectively conveyed through the pipeline system to reach treatment plants or other designated areas for processing.

Transporting wastewater is a critical aspect of maintaining the flow and preventing backups or overflows in the collection system. The pumps must be powerful enough to overcome resistance from the elevation change and any friction loss in the pipes. This process allows for efficient management and treatment of wastewater, ultimately protecting public health and the environment.

Other functions mentioned, such as treating wastewater or measuring its volume, are typically handled by different systems or equipment in a wastewater treatment facility, not specifically by the pumps in a lift station.
