Wastewater Technology Fact Sheet: In-Plant Pump Stations

pumping can reduce the size and cost of the wet well and allows the pumps to operate at maximum efficiency under a variety of flow conditions. Because variable-speed pumping allows pump station discharge to match inflow, only a nominal wet-well storage volume is required and the well water level is maintained at a near constant elevation.
