I think you’re a real light on those estimates my $30,000 did not include well heads being drilled. I have eight well heads and it’s a closed loop system you have to check open loop, close loop. Closed loop is better but more expensive.
I'm not a fan of the open loop systems. We have schools here that have done that. I don't know why the DNR let them do a pump and dump system. Closed ground loop is better I think. With a natural gas or electric back up.
