southern MN | I'm sure. Others mentioned you can go as big as you can afford.
Dad put a whole lot of 8, 10, and 12 inch mains, very little pattern tiling.
So I'm adding on to that with the pattern stuff.
We put in a 15 inch dual wall main a few years ago, through me and to a neighbor 2,200 feet or so. It goes down to a 12" dual wall, and 12 inch single when it gets to the neighbor.
It gets expensive over 15" at least here, you start to need some bigger trenchers and so forth, moving a lot of dirt.
Look at how many acres of land are on the 'bowl' you are trying to drain and set up the tile main big enough for that all to drain out that main. Eventually everyone will add enough tile to get it all flowing there.
