Knox County runs its own septic program under contract with the state, so you apply to the county office, not to TDEC. The rules are still Tennessee's, and a construction permit is good for three years from the day it is issued.
The ground around Karns
Karns sits in the Beaver Creek valley, between Beaver Ridge and Copper Ridge, west of Powell. Beaver Creek runs west through it to the Clinch.
The ground around Karns is mostly Fullerton, Minvale and Dewey soils, with Corryton and Heiskell in places. The USDA rates all of them very limited for septic fields, mostly for slow water movement and slope. Those are general ratings from the USDA soil survey. Your permit depends on a soil evaluation of your own lot.
What that means for the cost
Slow soil means a bigger drain field for the same house. A three-bedroom house needs about 2,250 sq ft of field on clay (typically $16,000 to $22,000 installed) against 375 sq ft on sand ($5,000 to $6,500). See the full breakdown on septic installation cost in Knox County.
Why the perc test comes first
Under Tennessee's septic rules, a new system is not permitted until the lot's soil has been evaluated, usually with a soil map drawn by a licensed soil consultant. That evaluation sets your field size and your price. Read more about perc testing near Karns, or try the numbers below.
