Sewage Pump Station – Basic Information for Technical Support
How Sewage Pump Stations Operate
Most sewage pump stations operate on a float-type system. As the wastewater flows into the wet well by gravity, the water level in the wet well rises until the maximum operating level is reached. At the high level, a float switch is actuated to turn on a pump. With the pump running, the water level falls. The pump keeps running until the water level reaches the low level. At the low level, another float switch is actuated to turn off the pump. The cycle is repeated several times during the day. The station can include a high water alarm that alerts you when the pump has failed or isn’t pumping out fast enough to keep up with the flow.
Types of Sewage Pump Stations
Five types of commonly used sewage pump stations include:
1. Submersible Non-Clog
2. Submersible Grinder
3. Wet-well Mounted (Vacuum or Self-primed)
4. Factory-built Dry Pit station with separate wet well
5. Built-in-Place Station with separate wet well
