Septic system Replacement

[Jeff R.]

Hi All, 

I am in the process of analyzing the cost of a flips rehab. One major cost is the property needs a whole new system. It has been determined the tank is no longer usable. Most of my flips have been within city limits, and the ones with a septic have had no issues. From experience, what are costs to consider when replacing a septic system in VA? From my research, I have estimated $15-$25k for an entire system, about $7k for tree clearing, and $2-3k for engineering diagram for the new system. I understand this question may sound vague, but this is my first with replacing a system.

Thanks for your input.
