Sewer or septic in Powell?
Hallsdale-Powell Utility District runs the sewer here, (865) 922-7547. Knox County's North County plan says public sewer is mostly limited to the area south of Copper Ridge, so a lot of homes north of the ridge, around Bull Run and the back roads, are on septic.

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 Powell
Powell lies in the Beaver Creek valley between Copper Ridge and Beaver Ridge, running from I-75 over to Clinton Highway. North of Copper Ridge the country opens out into Bull Run and Raccoon Valley.
Minvale, Dewey and Fullerton soils cover most of the ground around Powell, with Corryton and Apison on the slopes. The USDA rates them very or somewhat limited for septic fields: slow water movement on the clays, and slope on the ridges. 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 Powell, or try the numbers below.
