Wet Well Volume for Pumps w/ VFD

Wet Well Volume for Pumps w/ VFD

Wet Well Volume for Pumps w/ VFD

(OP)
In general what would you set the volume of a wet well to when using pumps with VFD's?  Max pump out rate is 2500 gpm.  The reason for the VFD is that the pump station receives flow from 8 pump stations and pumps directly into the headworks.  

Thanks

RE: Wet Well Volume for Pumps w/ VFD

Wet well volume depends on the method of pump operation. If you use variable speed pumps and the pumps match the flowrate to the inflow, the volume required is very small. This time is normally less than 1 minute retention. That time will allow for the change in capacity with a pump is started or stopped before the next start or stop point is reached.
