Cost for Septic System and Well

You know we can give you all kinds of numbers, because we’re from all over the place. You should get the prices from where you plan on building.
It depends on the soil, water table and vegetation. It all depends on the county and state regulations. You may need to have a designed system for septic system and that can be costly.
As for a well that can get costly too depending on how deep to get to a sufficient amount of water and how much rock they have to drill though to get to water.
It can cost a certain amount per foot for the first 100 feet and after that more per foot.

I retired after 40 years as survey tech and engineering tech for an engineering firm which sometimes dealt with design of site systems.
