We did this work today. The concrete rings will house the well equipment below the frost line. We trenches the power conduit and a frost free water line to the tennis court that will also be an ice skating rink. The rink needs year round water for making the ice and for the zamboni machine. We also have a 2" line for the irrigation system with will be seasonal. This property is a 14 acre estate that will have main house, guest house, barn, tennis/ice rink and two gunite pools. I have (3) 3hp submersibles each making about 45 gpm, 3 hunter 2 wire systems and 2" main everywhere. I will post more pics.
