I have a house that I think needs to have the septic system replaced. The house is located on a very flat area, and there is a high clay content in the soil, so water tends to lay on the ground if there is heavy rain or a big snow melts. The problem that I'm having is if there is a lot of rain my septic tank will fill up I think due to the ground not being able to absorb the water coming from the leach lines. That being said this has gotten worse over the years, I've lived here about twenty years and the house is about 30 years old. So I assume that there may be some damage to the leach bed area too. So my question is what would probably be the best benefit? Replace the leach lines and the soil around them or convert to an above ground mound system? Also any idea what either of these might cost me?
Thanks Joe
