This page is a citable record of what septic work actually costs in Knoxville and Knox County, Tennessee, in 2026. Every figure below carries its scope, a last-checked date, and a named source. None of them is a quote: only a provider who has seen your system can give you a price, and repair work always starts with a free on-site estimate. Figures were last checked November 4–6, 2026.
Pumping
| Service | Range | Scope | Source |
|---|---|---|---|
| Pumping, typical | $280–$520 | Knoxville area | East Tennessee 2026 ranges (Knox, Sevier, Blount, Hamilton) |
| Pumping, full range | $190–$890 | Knoxville area | HomeYou Knoxville directory estimate, updated Oct 17, 2026 |
| Pumping, second range | $200–$600 | Knoxville, general average | J&J Septic, Knoxville, FAQ |
| Pump-out + inspection combined | $300–$600 | East Tennessee, incl. Knox County | East Tennessee 2026 ranges |
The figure to plan around is the $280–$520 typical range. The $190–$890 full range is the same directory estimate's outer bounds, and the $200–$600 figure from J&J Septic is presented on that company's own site as a general average, not a Knoxville price list. Individual verified jobs in Knoxville, from Angi reviews of Rose Septic Tank SVC, run $325–$600, including one at $375 for pumping plus $40 for digging, which sits inside the typical range. One caution: some directories quote a small tank at $100–$200 and a 1,500–2,000 gallon tank at $200–$300. Those numbers conflict with the $280–$520 typical range from the same sources, so this page does not use them as headline figures.
Inspection
| Service | Range | Scope | Source |
|---|---|---|---|
| Inspection | $300–$500 | Tennessee statewide, not Knoxville-specific | Kings of Real Estate, Tennessee Home Inspection Guide 2026 |
| Inspection | $300–$500 | Knoxville directory estimate | HomeYou Knoxville, updated Sep 25, 2026 |
| Property-transfer inspection | Not published | No separate Knoxville price found | No local company or county source publishes one |
The $300–$500 inspection figure is a Tennessee statewide figure, labelled as such. No Knoxville company or county source was found publishing a distinct property-transfer inspection price, and no county transfer fee exists: in Tennessee there is no county-mandated property-transfer inspection programme, and an inspection here is typically lender-driven. A pump-out combined with an inspection typically runs $300–$600 in East Tennessee 2026 ranges.
Repair
| Service | Range | Scope | Source |
|---|---|---|---|
| Generic repair | Not published | Knoxville | Knoxville Septic Co., J&J Septic, Mr. Rooter Knoxville: free on-site estimate only |
| Tank-only replacement | $2,000–$7,000 | East Tennessee, incl. Knox County | East Tennessee 2026 ranges |
No local company publishes a generic repair price. Knoxville Septic Co. lists repair work, pumps, baffles, lines, and distribution boxes, but gives only a free on-site estimate. J&J Septic and Mr. Rooter Knoxville likewise publish no repair prices. That is not a gap in this page: it is the market. Any price for a repair depends entirely on what has failed, which is why repair work starts with an on-site assessment, not a price over the phone.
Drainfield and full systems
| Service | Range | Scope | Source |
|---|---|---|---|
| Drainfield, conventional | $5,000–$15,000 | East Tennessee, incl. Knox County | East Tennessee 2026 ranges |
| Drainfield, mound | $15,000–$30,000 | East Tennessee, incl. Knox County | East Tennessee 2026 ranges |
| Complete system, conventional | $12,000–$20,000 | East Tennessee, incl. Knox County | East Tennessee 2026 ranges |
| Complete system, mound / sand-filter | $20,000–$35,000 | East Tennessee, incl. Knox County | East Tennessee 2026 ranges |
| Complete system, general | $10,000–$30,000 | Knoxville area (Knox, Blount, Sevier, Loudon) | Knoxville Septic Co. |
Knox County sits on karst, limestone with shallow bedrock in places, and where the soil is too thin for a conventional drainfield, a lot needs a mound system instead. That is why the mound figures matter here more than in most places: a failed field on thin soil is a mound job, not a conventional one. A separate local real-estate source puts replacement at $7,000–$25,000, with basic gravity systems at $7,000–$12,000 and sand-filter or mound systems at $20,000 and above, which is consistent with the ranges above.
County fees and tests
| Service | Fee | Scope | Source |
|---|---|---|---|
| SSDS Installation Permit / drain field layout | $200 | Knox County | Knox County Health Department, Groundwater Services |
| Repair Permit | No cost | Knox County | Knox County Health Department, Groundwater Services |
| Verification / septic letter | $200 | Knox County | Knox County Health Department, Groundwater Services |
| Certification | $100 | Knox County | Knox County Health Department, Groundwater Services |
| Lot Evaluation | $40 | Knox County | Knox County Health Department, Groundwater Services |
| Perc test | $300–$800 | East Tennessee, incl. Knox County | East Tennessee 2026 ranges |
The Repair Permit is required before any work on a failing system, and it costs nothing. The Verification, sometimes called a septic letter, is usually requested for a real-estate transaction: the Health Department reviews its files and an environmentalist visits to confirm the system is working and that there is room to repair it. The SSDS permit fee is the county's published fee, not a contractor's charge.
What these figures are, and what they are not
These are published ranges from named sources, checked in November 2026, and they are the best public figures available for Knoxville. Very few local companies publish prices at all, which is why some lines say "not published" rather than inventing a number. Where sources disagree, this page says so instead of averaging them away. And where a figure is statewide rather than Knoxville-specific, it is labelled statewide.
One more figure worth knowing: Knox County's Stormwater Management grant programme may pay up to 75 percent of the cost of septic repairs or a sewer connection, where available. Our guide to the Knox County septic repair grant explains who qualifies and how to apply.
