What is a lift station or pump chamber, and when might it be used?

A lift station is a sealed chamber that houses a pump and float controls to move wastewater when gravity alone can’t do the job. It starts automatically when the wastewater level rises, pumping effluent to a higher elevation or into a pressure-distribution line to the drainfield. This is needed in areas with flat terrain, long sewer runs, or elevations that would prevent gravity flow from the septic system to the drainfield. The essence is lifting and moving wastewater to a higher point for distribution, rather than simply filtering solids or backwashing, and it creates or maintains the necessary flow when gravity isn’t feasible.
