You make valid points, here. It seems to me that the best answer is for
Tony to get 3 or 4 estimates. Since he lives in Knoxville it really doesn't
matter what a septic field dug in a different locale, for a different sized
house, in different soil, and complying to a different health code will
cost. this is an "apples to oranges" comparison. The cost of his septic
system will be one of the cheaper estimates that he gets on his home.The
idea that he is "investigating" the cost by posting here is misguided.
