Pumping a standard 1,000-gallon septic tank in Texas costs $267 to $650 in 2026 — the full span of the two verified price series we track: Angi’s Houston-area data ($267–$490, average $375) and published Hill Country provider pricing ($350–$650, Dillon Septic). Nationally, Angi puts the average pump-out at $427, with most homeowners paying $291–$563. Your price moves with three things: tank size, how hard your lids are to reach, and how long it’s been since the last pump-out.

A 1,000-gallon tank — the most common size in Texas homes — runs $325–$700 nationally and $350–$650 from Central Texas providers, and every step up in tank size adds roughly $100–$200. Bigger tanks mean more gallons hauled and higher disposal fees at the treatment plant, which is why pumpers price by capacity first.
Two current datasets, side by side — a national cost survey and published 2026 pricing from a Hill Country pumper:
| Tank size | National range (Angi, Apr 2026) | Central Texas provider (Dillon Septic, Feb 2026) |
|---|---|---|
| 750 gallons | $250–$550 | $275–$450 |
| 1,000 gallonsMost common | $325–$700 | $350–$650 |
| 1,250 gallons | $375–$900 | $450–$850 |
| 1,500 gallons | $450–$1,100 | $450–$850 |
| 2,000+ gallons | — | $700–$1,200 |
Not sure what size you have? Most Texas homes built since the 1990s carry 1,000–1,250 gallons for three to four bedrooms. Your county’s permit file lists the exact tank specs — in a county like Kerr, the environmental health office can pull the original schematic on request.
Houston-area homeowners pay $267–$490 (average $375) per pump-out — among the lowest verified rates in the state — while Hill Country jobs commonly quote $350–$650 for the same 1,000-gallon tank. Provider density drives the spread: metro Houston has dozens of competing pumpers, while a ranch outside Junction might be an hour from the nearest vacuum truck.
| Region | 1,000-gal scheduled pump-out | Basis |
|---|---|---|
| Houston area | $267–$490 (avg $375) | Angi Houston cost data, May 2026 |
| Hill Country / San Antonio corridor | $350–$650 | Dillon Septic published 2026 pricing (Comal County) |
| National baseline | $291–$563 (avg $427) | Angi, Apr 2026 |
We haven’t found an independently published 2026 price series for Austin or Dallas–Fort Worth specifically; expect quotes there to track the statewide band, with growing exurbs (and anywhere trucks queue for limited disposal sites) trending toward the top of it. When a source worth citing appears, this table gets a row — that’s how every number on this page works.
Rural Texas adds one more line item: distance. Pumpers charge travel or trip fees when your property sits well outside their route territory, and in thin-provider counties there may be only one or two companies to call — which is why we organize our directory county by county. Ask two questions before booking: “Is there a trip charge to my address?” and “What’s your disposal fee situation?” Both get baked into rural quotes.
Buried lids, years of neglect, and grease are the three most common reasons a $400 job becomes a $700 one. The quote assumes the truck can park near an exposed lid on a tank pumped within the past five years — break any of those assumptions and the meter runs.
The big adders, from 2026 cost data:
Locating and digging. If your lids are under 18 inches of St. Augustine and nobody remembers where, the crew digs by the hour. In one Central Texas example this year, a tank buried under a stone patio pushed a routine pump-out to $850 (Dillon Septic, 2026). A one-time riser installation brings the lid to grade and ends the digging fees permanently — it typically pays for itself within two or three pumpings.
Neglect surcharges. A tank that’s gone seven-plus years accumulates compacted sludge that takes extra time and water to break up. A rental property in that condition ran $720 against a $480 norm in the same 2026 provider data.
Grease. Heavy fat, oil, and grease loads clog hoses and take longer to evacuate — Houston-area data shows severe cases adding up to $400 (Angi, May 2026).
Add-on services. Filter cleaning, effluent-filter replacement, or baffle repairs add roughly $200–$600 when needed (Angi Houston data, May 2026). Ask the crew to show you the worn part before approving it.
Timing. Same-day and after-hours calls carry premiums. Published Texas figures for emergency surcharges are inconsistent enough that we won’t print one — ask the dispatcher for the trip fee and the after-hours rate before the truck rolls. If sewage is already backing up, read our first-hour emergency guide while you wait.
Aerobic pump-outs price in the same band as conventional tanks, but the schedule works differently: your licensed maintenance provider tracks sludge at each required inspection and tells you when it’s time. Aerobic Treatment Units, or ATUs, are a popular choice for Texas homes, because so much of the state’s ground — Hill Country limestone, Blackland clay, wet East Texas timberland — can’t pass the soil evaluation a conventional buried drainfield needs. The permit ledger shows how popular: systems with surface spray irrigation, which require aerobic pretreatment, made up 57% of the 42,097 septic authorizations Texas counties issued in 2024 (TCEQ OSSF annual reporting data). State rules require most ATUs to be inspected every four months by a TCEQ-licensed maintenance provider.
Three things aerobic owners should know before paying for pumping:
First, your maintenance contract — $200–$600 a year, the full span across Dillon Septic’s published 2026 pages (its general and aerobic-specific guides quote different bands; we print the envelope) — covers inspections, not pump-outs. Pumping is billed separately when sludge levels call for it, usually on a cadence similar to conventional tanks. Details on what contracts must include are in our aerobic maintenance contract guide.
Second, an aerobic system has multiple compartments (trash tank, aeration chamber, pump tank), and a proper pump-out addresses the right ones. Confirm the company holds the TCEQ Maintenance Provider license — that’s the credential for servicing aerobic units, and not every pumper has it.
Third, don’t let anyone talk you into pumping the aeration chamber “on schedule” without a sludge measurement. Measured need, not the calendar, is the trigger — that’s also the EPA’s guidance for any tank: pump when sludge and scum exceed about a quarter of the liquid depth.
Every three to five years for most households, per the EPA — and skipping a $400 pump-out is how homeowners end up with four-figure repair bills. Solids that overfill the tank migrate to the drain field, and once the field clogs you’re no longer buying maintenance, you’re buying repairs: Angi puts average septic repairs at $1,830.
Frequency by household, from Angi’s 2026 data:
| Tank size | Home size | Pump about every |
|---|---|---|
| 750 gal | 2 bedrooms | 5 years |
| 1,000 gal | 3 bedrooms | 3 years |
| 1,250 gal | 4 bedrooms | 3 years |
| 1,500 gal | 5 bedrooms | 2–3 years |
Garbage disposals, big households, and short-term rentals all push you toward the early end. Texas adds its own wrinkles — heavy clay soils and drought-stressed drain fields don’t forgive an overloaded tank. Full workup in our pumping frequency guide, and if you’re seeing slow drains or odors now, start with the signs your tank is full.
Every legitimate septic professional in Texas holds a TCEQ license or registration you can verify online in under two minutes — and checking it is the single best filter against fly-by-night pumpers. This is the step the lead-gen sites tell you to do without ever showing you how. Here’s how.
A standard pump-out should include full evacuation of liquid and sludge, a look at baffles and inlets, disposal fees, and a written receipt noting tank condition. Get that receipt — it’s your maintenance record when you sell the house, and Texas buyers’ inspectors ask for it.
Red flags worth walking away from: door-to-door “your neighbor said you need pumping” pitches, quotes wildly under the ranges on this page (partial pump-outs that leave sludge behind are the classic bait), and any crew that can’t tell you where they legally dispose of septage.
A trustworthy Texas pumping quote itemizes five things: the base pump-out for your tank size, disposal, any digging or access work, add-on services, and trip or after-hours fees — anything quoted as one round number deserves a follow-up question. The itemization is your protection on both ends: it stops surprise charges when the truck arrives, and it lets you compare quotes that would otherwise look identical.
Ask two questions before you book. First: “Does that price include pumping both compartments and the disposal fee?” Some low quotes cover evacuating liquid only — the sludge that stays behind is the part you’re paying to remove. Second: “Where do you dispose?” A legitimate answer names a permitted treatment facility; hesitation is your cue to call the next company on the list. In rural counties, also confirm the trip charge up front — it’s a legitimate cost of doing business out there, but it belongs on the quote, not on the invoice.
Plan on $267–$650 — Houston-area jobs verify at $267–$490 with a $375 average (Angi, May 2026), and Hill Country provider pricing runs $350–$650 (Dillon Septic, Feb 2026). For a feel of “normal”: Dillon’s published example for a family-of-four tank pumped on schedule was $480. The high end of every range reflects difficult access or long-neglected tanks, not a better pump-out.
For a 1,000-gallon tank with exposed lids and a 3–5 year service history, $500 sits at the high edge of normal — get a second quote; for a larger tank, buried lids, or years of buildup, it can be fair. Ask for the line items: base pump-out, digging, disposal, add-ons. A good pumper itemizes without being pushed.
Most residential pump-outs take 45–90 minutes on site (Dillon Septic, 2026). Add time if the crew has to locate and dig lids, or if compacted sludge needs to be broken up and rinsed.
Install risers, keep a steady 3–5 year schedule, and get two or three quotes from TCEQ-verified providers every time. Risers kill the recurring digging fee, staying on schedule avoids neglect surcharges, and in metro counties quotes for the identical job can differ by $100 or more. What you should never do is stretch the interval to “save” — the repair math never works in your favor.
More — same-day and after-hours calls carry real premiums, but published Texas figures vary too widely for us to print a reliable number. Get the after-hours rate and trip fee quoted before dispatch, and use our emergency backup guide to limit damage in the meantime. If the “emergency” is recurring, the tank isn’t your problem — the system is.
