Details that help you get an accurate quote

• Tank size or bedroom count: Tennessee’s Rule 0400-48-01-.08 sizes tanks by bedrooms (750 gallons for two or fewer, 900 for three, 1,000 for four, plus 250 for each additional bedroom), so if you don’t know the gallons, the number of bedrooms gets a company close. Pumping is usually priced by tank size.
• When it was last pumped: the EPA says household tanks are typically pumped every three to five years. “Never, as far as I know” is a useful answer too.
• Whether the lid is exposed: a riser at grade, a lid a few inches down, or no idea where the tank is. Locating and digging to a buried lid is usually an extra charge, so say so up front and ask for a flat fee.
• What you are seeing: slow drains or gurgling, a sewage odor outdoors, a wet or unusually green strip over the drain field, standing water near the tank, an alarm on a pump system, or a backup inside the house.
• Any event: a home sale with a closing date, an addition or pool going in over the system, a heavy-rain backup, or a tank that was pumped recently but is backing up again. If a sale is involved, mention whether the buyer wants a septic inspection letter; Tennessee Real Estate Commission Rule 1260-02-.37 requires the agent to tell buyers that a government inspection letter is available for a fee.
• Access: how far the tank is from where a truck can park, whether there is a gate or a steep drive, and whether the property is on a ridge-top road. Vacuum hoses have limits, and distance can change the price.
• Photos: a shot of the lid or riser, the area over the drain field and any wet spots helps a company quote faster.

Before the companies call

Ask every company for its TDEC Septic Tank Pumping Contractor permit number (Rule 0400-48-01-.20) and, in Hamilton County, its county pumper license, and check them against TDEC’s “Installers & Pumpers DataViewer” and the county’s 2026 “List of Septic Installers and Pumpers,” both of which are public. For repair or drain field work, ask for the TDEC installer permit (Rule .19) and the county installer license, and ask who will pull your $40 repair permit from Hamilton County Groundwater Protection. Tennessee has no septic-inspector license, so for an inspection ask what the written report will cover. Our about page has the full list of questions to ask.

Wondering about price? Septic tank pumping typically runs $175–$300 for a 750-gallon tank, $225–$400 for 1,000 gallons and $345–$600 for 1,500 gallons, with a national average of about $400; a standard septic inspection runs $100–$200 and a camera inspection $250–$1,175. These are typical national ranges from Fixr (2025) and HomeAdvisor (2026), estimates, not quotes. See the cost guide for ranges by job, and how the process works.

Timing matters more than most people expect. Chattanooga’s December through March window averages about 20.6 inches of rain, when drain fields in the county’s clay soils stay saturated longest, while August through October are the driest months at 3.6–4.2 inches each (NOAA 1991–2020 normals, Lovell Field). Requesting quotes in late summer or early fall means drier ground for a truck, a probe or a trench, and more open schedules than the week after a storm.
