To be able to turn my machinery inside the mill, using 3 500 gpm pumps, instead of a mill dam which is not a possibility at this point.  

Anyone know of any overshot wheels that uses a recirculating pump to draw water out of tail race back up to flume? Any that I can go visit?

Does anyone know of mills with overshot wheels being fed water by use of inverted pumps in the SC, NC, VA, TN area?

Thank you Carl for the response.... I will utilize the info you shared.
If I want to make the components inside the mill work, then how would one go about figuring that up?

I am in the middle of restoring my family's old grist mill. My grandfather started using a power unit in 1947 instead of sluices and a mill dam.  I would like to return to a water run mill.
Instead of the original mill dam that was used, but now extinct, I am going to run water in by use of pipe. However; I need to know what size pipe I need to run my overshot wheel.  4,6,8,10 inch?
My overshot wheel is metal and is 24 ft tall, 72 buckets, buckets are 24 inches wide, and 7 1/2 inches deep.  Any ideas, formulas, or suggestions would be much appreciated.  
Thanks
