Lift Stations · Lift Station Purpose and Types
Why Does Wastewater Need a Lift Station?
Wastewater normally moves downhill through gravity sewers. Lift stations are also called pump stations or pumping stations. Where the land rises, a sewer becomes too deep, or gravity flow cannot reach the treatment plant, a lift station raises the wastewater. The station then sends it through another gravity sewer or a pressurized pipe.
A force main is a pipe that carries wastewater under pressure from a pump. Unlike a gravity sewer, it may travel uphill. The pumps must overcome elevation and resistance inside the pipe while moving the required flow.
A lift station does not provide wastewater treatment. Its job is reliable conveyance. A failure can cause a backup, overflow, equipment damage, or an interruption at the treatment plant.
Operators protect this link by observing conditions, testing equipment, recording results, and reporting problems before available storage is lost.
Key point: A lift station moves wastewater when gravity alone cannot provide dependable flow.
