Mine lay on the surface other then the first 700 feet which is buried 6 inches deep, we are quite rolling so just have taps and drain it in the low spots.
Edit: additional question: has anyone ever just let it freeze?> I know you can when an end is shallow as long is it is covered so it only freezes and thaws once per season, in other words it fully thaws before it freezes again.
I have a gravity system off a dugout with 1.75 miles of 1.25” 75psi poly pipe with 18” of cover. The lines are above ground where it fills open top tire troughs in 3 locations. There’s over 140’ of drop as it has over 60 psi at the end of the line.
I used it blow it out. One fall I had lots of grazing and just let it run wide open to keep the troughs open and the line from freezing while grazing. It worked till we had a week of below -20C 0F. It froze up and I just left it. Come spring I only had to replace one ball valve that had split.
Ever since I just close the shutoff valves at the troughs and walk away. I usually end up replacing a shutoff valve ( gate valves seem to handle the freezing better than ball valves) and sometimes a cheap Ritchie float valve. Been doing that over 20 years and no plans on changing.
