How to search the state's septic file, pick out the right site sketch, and what to do when an old system left no trail online.
Tennessee septic records live in TDEC's free online SSDS Record Search, not at the county. Pick Maury County, then search the address, permit number, or a current or former owner's name. Download the permit and site sketch. Older homes often have thin or missing files. If nothing turns up, call TDEC's Columbia office at 931-380-3371.
Use the button on this page or TDEC's septic-program page. The county property and tax sites don't have septic files. The viewer tends to behave better on a desktop browser than a phone.
Start with the street address and leave the other boxes blank. Filling every field at once is the usual reason a real file doesn't show up. Older files can sit under a rural route or an old road name.
Search the seller's name, then earlier owners from the deed chain. The permit was filed under whoever applied, which may have been the builder or an owner from decades ago.
Check the address, permit date, owner, lot number, and bedroom count against the house. A matching surname or the house next door isn't good enough. Save the permit, sketch, and attachments in one folder.
Look for measurements from the house corner, road, or a power pole. Mark the tank, field lines, backup area, and well on a printout. Then have someone probe for the tank before you dig.
Call or email the Columbia Environmental Field Office with the address, parcel number, owner names past and present, the house's rough age, and anything partial you found. Staff can sometimes find what the public search misses.
If the screens look different from these steps, TDEC has updated the viewer. Go back to the official SSDS record search instead of paying for a third-party property report. The state search is free.
One Spring Hill wrinkle: Williamson County is one of nine Tennessee counties that run their own septic program under contract with the state, per TDEC's septic contacts page. If the address is on the Williamson side of Spring Hill, start with Williamson County.
Tennessee calls the drawing a permit site sketch. Most people call it the layout or as-built. Either way, it's less precise than a survey.
| Record | What it can tell you | What it cannot prove |
|---|---|---|
| Construction permit | Approved system category, design details, design flow or bedrooms, issue information, and permit conditions | Current operation, maintenance history, or a promise that later additions are approved |
| Permit site sketch | House reference, tanks, field lines, duplicate area, water source, property boundaries, setbacks, and landmarks when recorded | A precision survey, a current underground locate, or proof that every component sits exactly as drawn |
| Soil map and notes | Mapped soil areas, interpretations, site features, and the information used in the permit review | Approval to move the house or disturb the initial or duplicate disposal areas |
| Repair permit | The state-approved repair area and components covered by that repair record | Every maintenance visit, pumping event, or unpermitted alteration since the repair |
| Engineered attachments | Design package, calculations, equipment, controls, or other specifications attached to an alternative permit | A substitute for current service records, alarm checks, or equipment inspection |
TDEC's current standard, updated in 2024, requires digital site sketches with measurements someone can repeat in the field, from the house and tanks to the backup area and setbacks. Files from before then are hit or miss.
“Not found online” and “never permitted” are different problems. Plenty of real files sit under a former owner, a subdivision name, or an old rural route. Tennessee started scanning old septic records county by county around 2017, and not every older file made it in complete. Ask TDEC to look with the clues you have.
Age matters. A house from the 1960s is a harder search because its system may predate modern paperwork or may have been replaced since. Some older Maury homes have a file; many have only a thin one.
If the file remains missing, hire a qualified septic inspector, pumper, or installer to locate the tank and field on the ground. They'll trace the sewer line out of the house, probe, or use a locator. Keep trucks off the likely field, never climb into a tank, and call 811 before any digging near buried utilities.
Start with bedrooms. If the listing says four and the permit says three, that's a question for TDEC before closing. Then hold the drawing up against the property. A pool, garage, or new driveway built over the drainfield or the backup area is a real problem, and the old permit doesn't stretch to cover it.
Then order an independent condition inspection. The drawing can't show sludge depth, a broken baffle, or a dead pump. Leave enough days in the inspection period to find the system, open it, and price any repairs.

In TDEC's free online SSDS Record Search. The Maury County property and building-permit sites don't hold septic files; the state does. Open each likely result and check the address, owner, and drawing against the house. If you can't pin it down, call the Columbia Environmental Field Office at 931-380-3371.
A good one shows the house, the tank, the field lines, the backup (duplicate) drainfield area, the well, property lines, and the permitted bedroom count, with measurements from fixed points. Newer files often attach the soil map. Older sketches are thinner, sometimes just a hand drawing with a few distances.
Most often the file sits under an earlier owner's name or an old rural-route address. Search with fewer fields filled in, then try former owners from the deed. Some older files were never scanned or never existed. An empty search just means you need to call TDEC and have the system located on the ground.
Not always. The sketch shows what was approved and roughly where. Installers sometimes shifted things, and the tree or shed used as a reference point may be gone. Treat the drawing as a head start, and have a septic pro find the tank on the ground before anyone digs.
No. Check that the permit's bedroom count matches the house, then get an independent septic inspection inside your contract period. The record tells you what was approved years ago. Only an inspection tells you whether the tank is sound and the field is still working today.
For the Maury County side of Spring Hill, yes, search Maury in TDEC's viewer. Part of Spring Hill sits in Williamson County, which runs its own septic program under contract with the state. For an address on the Williamson side, check with Williamson County's sewage disposal program first.
