How It Works

1. Wastewater or stormwater flow via gravity from a residential, business, or municipal sources through underground pipes into the pump station wet well positioned at a lower elevation.
2. When the fluid rises to a calculated level in the wet well, a mechanical float switch triggers the pump to start discharging the wastewater out of the wet well.
3. The pump lifts the fluid upward and out of the wet well through a pressurized piping and valve system.
4. The fluid travels onward until it reaches a point of connection with a main storm or sewer system via gravity.
5. The main sewer or storm drain system conveys the fluid to its final discharge location at a detention reservoir, infiltration basin, or treatment facility for reuse.
