What the ground in Sevierville is like
The USDA soil survey rates mapped ground in Sevierville for septic drain-field suitability across roughly 25 square miles. About 80% of the rated ground is classed "Very limited", meaning the soil has one or more features unfavorable for a conventional drain field, and the limits generally cannot be overcome without major soil reclamation, special design or expensive installation.
In Sevierville, the leading limit is slope: the ground falls steeply enough that a level trench line is hard to hold. A drain field has to sit across the grade without concentrating flow downhill; on steeper parcels that layout gets tighter. The survey flags that limit on about 64% of the rated ground here.
