Buying property tips?

Out here what type of septic system is governed by property size, or so I was told. What type of system is alloeed? How deep is the well? Gallonage? Lenders require a certain flow. Power? No easements? Rocky?
Trash service? Rural areas are often serviced by private companies.

I read somewhere that you should do several "perks". Maybe drainage changes, so may look into re perk request. I believe it's approved for 3 bedroom conventional system, but I need to verify that thanks. I've seen the well certificate, not sure of the depth, think it's a 6 inch and a nice pump house has been built, previous owner was going to bring power to that part of the property, which is nearer to the road/power source, and put a panel in the well house, then run power up to the house into another panel. He had already trenched it, but think that was several years ago. No easements, not too rocky and yep, no more city water/sewer/garbage bill, I'll be going to the dump I guess. Don't mind the dump. There is a charge for keeping the road maintained, it's a bit too but I guess it's a community thing.
