Septic System Anatomy
Lift Station
A lift station (also called a pump station) is a wastewater pumping facility that collects sewage or effluent that cannot flow by gravity and pumps it uphill to a higher elevation in the system. In private septic applications, a lift station is typically a buried chamber with a submersible pump and float switches that activate the pump when liquid reaches a set level.
Lift stations are common in low-lying areas, neighborhoods with flat terrain, and systems where the treatment components are located uphill from the generation points. They require regular maintenance: pump inspection, float switch testing, and occasional cleaning of the wet well. Most residential lift stations have audible and visual alarms that activate if the pump fails or if the liquid level rises above normal — these alarms should be tested periodically and never ignored.
What This Means for You
If your property has a lift station, include it in your regular service schedule. A failed lift station pump that is caught early is a straightforward repair. One that is ignored until sewage backs up into the house is an emergency. Know where the alarm panel is and what a normal versus alarm condition looks like.
