FWIW My well is 5 inch, 1.5 HP constant pressure variable speed pump that delivers 35 GPM at 60 psig. I can raise my approximate 1/4 acre 5 to 6 inches in 48 hours. I have a water table pond so the 35 GPM also has to make up the leakage back to water table during the 48 hours of pumping.

Edit: The reason I sized mine so large is it also provides water to the house and my geothermal pump and dump.
