As I mentioned I am working on wet well design.There are two submersible pumps (one duty+ one standby). I am not clear about pump cycle time and how to find out pump on/off switch depth in the wet well. The pump is not VFD . Its continuous.The invert elevation of the incoming sewer is 9.23 ft below from the top of the well. wet well is 7 feet dia. The depth of the wet well is 15.6 feet. The discharge pipe is 3.93 feet below the top of the wet well. The pump is flygt submersible pump.Inflow is 350 gpm @ peak flow.Please give me some tips. Thanks.

Wet-well maximum detention time with constant speed pumps is typically 20 to 30 minutes. Limit the pump cycle time to less than 10 starts per hour
