How do i insulate a piecr of corrugated pipe?

This 4' diameter piece of pipe is sunk in the ground and sits about 3' below ground with another 2' above ground and houses the pressure tank for our well. It is only covered by a piece of plywood and a tarp. Inside, the previous owner had a bunch of glass batts wrapped around the tank and tied with string. He says that he hasn't had a problem in the 5 years that it has been there but the winters haven't been that bad of late. I'd like to do a better job of this. I thought that I'd cut a 4" thick by 4' wide circle of foamboard and lay it on supports just above the tank to avert some of the cold from above but I thought that I'd like to insulate the sides of the pipe but with what and then I may have an issue getting the circle out if I need to service the tank, depending on what is done with the walls. I'd like to hear some suggestions for capping the top too, with relatively easy access in mind. TIA, Czzzzzz

A couple of suggestions: fill it with foam packing peanuts or rice or wheat straw. Attach 4" of foam board to the inside of the lid.

The foam/ lid attachment would be the most logical but it would leave the

2' of exposed pipe uninsulated and defeat the insulation. The peanuts and the straw are good insulators but not if I need easy... Ohhhhhhh, you mean to put them in large bags so they aren't all over the place, right?! Hmmmmm, that has some merit. I have lots of straw and no 'peanuts' so I guess I know what I'll be using. Thanks!

Depending on the "frostline" whereever you are, you may only want to insulate above the frostline. Ground heat would help keep it warm.
