First 5 things to do right now
- Stop all running water in the house. No showers, no laundry, no dishwasher, no filling the pet's bowl. Every gallon makes it worse.
- Don't flush any toilet. A single flush on a backed-up system can push sewage up through the lowest fixture in the house.
- If sewage is already in a tub/shower, close the drain to slow the rise. Don't step in it.
- Keep kids and pets out of any yard where you smell sewage or see standing water. It's a health hazard until cleaned up.
- Take a photo if it's safe (do not open the septic tank lid yourself — the atmosphere inside can be dangerous). Then call the line.
What's actually happening
A septic backup is what happens when the tank can't take any more water and effluent pushes back up the drain pipes. Three main causes, in rough order of frequency around Wichita Falls:
Cause 1: Full tank. The tank hasn't been pumped in a long time — often 6+ years. Sludge and scum fill it to the point where liquid can't enter or leave. The fix is a pump-out. Once pumped, most backups clear within an hour and normal use can resume.
Cause 2: Saturated clay drainfield. This is the distinctly local one. The red clay under Wichita, Archer, and Clay counties drains slowly on its best day, and after a spring storm run it holds water for a week. When the ground around the drainfield is saturated, effluent can't soak away, the tank stays full no matter what leaves the house, and drains crawl or back up — from Holliday to Iowa Park to the lake lots at Arrowhead, the calls stack up in the days after heavy rain. A pump-out buys immediate relief; whether the field itself needs work depends on how it behaves once the ground dries.
Cause 3: Blockage between house and tank. Tree roots, a collapsed pipe, or a wipes-and-grease clog in the main line. The tank might be fine, but nothing can get to it. The fix is a snake or hydro-jet on the line, sometimes an excavation to repair.
The pro who calls you back will diagnose which of the three you're facing before the pump truck touches anything.
What it might cost around Wichita Falls
Best case, if it's just a full tank: a routine pump-out — most run in the $300–$650 range in this area depending on tank size and access — resolves it in one visit, one afternoon. After-hours work runs above daytime rates.
Middle case, if it's a line blockage: pump-out plus line clearing. More than a straight pump, but still usually a same-day fix, and quoted before anyone starts.
Worst case, if the drainfield has failed: pumping buys you days of breathing room, but a field that's finished — not just waterlogged from a storm — means repair or replacement work that runs well beyond any pump-out. Nobody can price that over the phone honestly; the pro will lay out the options after seeing how the system behaves.
Whichever case you're in, you hear the number before the work starts — not after.
What NOT to do
- Don't dump enzyme or bacteria "septic tank cleaners" into a backup. They don't work in an emergency; they take weeks to affect anything.
- Don't try to pump the tank yourself with a shop vac or trash pump. Sewage handling requires TCEQ-licensed sludge haulers by law.
- Don't open the septic tank lid yourself. Confined-space hazards are real.
- Don't ignore a smell that "goes away" after you stopped using water. The backup is still there — you just stopped feeding it.
- Don't assume rain was the whole story. Saturated clay exposes a weak system; a healthy one rides out a wet week. If it backed up in the storm, get it checked after the storm.
- Don't shame yourself for how long it's been. Every pumper in North Texas has seen 15-year-neglect tanks. Nobody's judging — they just want to fix it.
Preventing the next backup
Pump on schedule. Every 3–5 years for conventional tanks; aerobic units on their own service cycle. This one habit prevents the majority of backups. Learn more →
Know where your tank and drainfield are. Half the calls to this line start with "we don't know where the tank is." Your county OSSF permit file usually has the site drawing.
Watch what goes down the drain. "Flushable" wipes are not septic-safe. Neither is grease, coffee grounds, feminine products, or paper towels.
If you're on an aerobic system, keep the maintenance current. A serviced unit warns you with an alarm before it fails outright. Aerobic system service →

Backup FAQs
How fast can someone get to me?
Same-day is the goal during business hours, and most calls are returned within the business hour. After hours it's callback first, then drive time. Addresses in Wichita Falls proper are quickest; rural spots out toward Electra, Archer City, or Henrietta add drive time on the FM roads.
It backed up during a rainstorm. Will it fix itself when things dry out?
Sometimes drains improve as the saturated clay dries — but that's a symptom pausing, not a problem solved. A drainfield that quits every time it rains hard is telling you the tank is overdue for pumping, the field is overloaded, or both. Get it looked at before the next storm run.
What if it's Sunday night?
Same call, same line. Weekend response times are a little slower but the dispatch is the same — see emergency septic service. Most weekend backups are pumping-solvable, so it's usually one visit not two.
Should I call my plumber or a septic pro?
Septic pro first, always, when there's a chance the tank is involved. A plumber can clear a household drain clog, but plumbers are not licensed to open or pump septic tanks in Texas.
My insurance policy says it covers "sudden and accidental" damage — is a backup covered?
Depends on the policy. Sudden backups from a discrete cause (tree root break, mechanical failure) are sometimes covered; chronic slow buildup is almost never covered. Get the pro's written invoice and diagnosis — that's what your adjuster will want.
