How It Works

1. Wastewater or stormwater flow via gravity from a residential, business, or municipal sources through underground pipes into the Mini-Muni Grinder 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 non-clog or grinder pump to start discharging the wastewater out of the grinder pump station wet well.
3. The non-clog or grinder pump lifts the fluid upward and out of the wet well through a pressurized piping and valve system.
4. The fluid exits the Mini-Muni pump station and travels onward until it reaches a point of connection with a main storm or sewer system via gravity.
