Septic work is all we do
Public sewer stops at the edge of Knoxville's growth, and growth is winning. The subdivisions filling in around Powell, Halls, Karns, and Hardin Valley, the acreage lots in Corryton and Seymour, and most of rural Blount County all run on septic. Those systems age, they get undersized as houses grow, and East Tennessee clay and limestone make some lots harder than others. That is the whole of our business: designing, installing, and keeping septic systems working in this soil.

Typical Knoxville septic prices
These are typical ranges for this area, from real Tennessee cost data. They are planning numbers, not a quote: soil, slope, lot size, and the system your permit allows all move the final figure. Your exact price is set in writing after a site visit, before you commit to anything.
| Service | Typical range | What it covers |
|---|---|---|
| New conventional installation | $7,000 to $12,000 | A complete new system for a typical homesite: tank, drain field, permit, and inspection. |
| Engineered or advanced system | $15,000 to $25,000 or more | For slow soils, high water tables, small lots, and steep sites common in East Tennessee. |
| Septic tank pumping | $300 to $600 | Full pump-out of the tank, both compartments, with a visual check while it is open. |
| Real estate inspection | $450 to $800 | A documented inspection for a sale or purchase, with a written report. |
| Repairs | Quoted after diagnosis | Baffles, lines, pumps, and distribution boxes priced on site. A failed drain field that has to be replaced falls in the same range as a new installation. |
How an installation works
- Tell us about the property. Address, number of bedrooms, what is there now, and what is going wrong if anything. About a minute through the form, or one phone call.
- Site visit and soil evaluation. We look at the lot, the existing system if there is one, and the soil. Soil decides what kind of system your permit will allow.
- Written price and permit. You get the full price in writing, and we file the permit paperwork with the state environmental health program.
- Installation and inspection. Most conventional systems take two to four days on site. The system is inspected before it is covered, and you get the paperwork.
Where we work
Knox County first, plus the septic-dependent edges of Blount and Sevier counties. If your lot is on a well and a septic tank, you are in our territory.
Frequently asked questions
How much does a septic system cost in Knoxville?
A conventional new septic system in the Knoxville area typically runs $7,000 to $12,000 installed. Engineered systems for difficult soils run $15,000 to $25,000 or more. Pumping runs $300 to $600 and a real estate inspection $450 to $800. Your final price is confirmed in writing after we see the site, the soil, and the permit requirements.
How long does a new septic installation take?
Most conventional installations take two to four days of on-site work once the permit is in hand. The permit and soil evaluation come first, and that paperwork usually takes longer than the digging. Engineered systems and wet weather add time.
Do I need a permit for a septic system?
Yes. New systems and major repairs in Tennessee need a permit through the state environmental health program, and the finished system is inspected before it is covered. We handle the permit paperwork and schedule the inspection as part of the job.
How often should a septic tank be pumped?
Most households should pump every three to five years. Big families, garbage disposals, and smaller tanks shorten that window. Skipping pumping is the most common reason a drain field fails early.
Can a failed drain field be repaired, or does it have to be replaced?
Sometimes it can be repaired. A crushed line, a bad distribution box, or a failed pump is a repair. A field that is saturated or undersized for the house has to be replaced or expanded. We diagnose first and price the fix in writing before any work starts.
What are the signs my septic system is failing?
Slow drains throughout the house, gurgling plumbing, sewage odors, wet or unusually green ground over the drain field, and backups into the lowest fixtures. Any one of those is worth a visit before it becomes an emergency.
Backups do not wait. Neither do we.
