The design of wet wells for storm water pumping stations requires careful study where vertical axial flow or diffusion vane pumps are installed taking suction directly from the wet well.

Inflow to the station will vary significantly between dry seasons and flood events. These pumps are very sensitive to inflow arrangements spacing between the units and clearances from the bottom and sidewalls. The most reliable pumps should be used together with a sound station design to ensure secure operation. The typical design process starts with understanding what type of water needs to be pumped and the volume of that water.
