Sewer or septic in Maryville?

Who issues septic permits in Blount County

Blount 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 Maryville

Maryville sits where Ellejoy Creek meets the Little River, with Chilhowee Mountain rising to the south.

Dewey and Decatur soils, both deep red clays, cover close to half of the ground around Maryville, with Sequoia and Litz on the shallower slopes. The USDA rates Dewey and Decatur somewhat limited for septic fields and the shallow soils very limited. 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 Maryville, or try the numbers below.
