Alarm going off? Sprinkler heads spraying gray water? Aerobic systems are everywhere on the South Plains — and they need real maintenance, not neglect.
Call (806) 000-0000Drive through the newer acreage developments outside the Lubbock city limits — around Shallowater, Wolfforth, New Deal, or south toward Woodrow — and you'll spot the telltale purple-topped sprinkler heads in the yards. That's an aerobic treatment unit (ATU), the system most commonly installed in this area over the past two decades. West Texas soil conditions — shallow caliche, tight clays in spots, and slow percolation — often rule out conventional drainfields, so county-approved designs frequently call for aerobic treatment with surface spray irrigation instead.
Aerobic systems treat wastewater to a much higher standard than a conventional tank, but they're also machines: they have an air compressor, a pump, floats, a chlorinator, and spray heads — and every one of those parts can fail. Texas rules recognize this: TCEQ requires aerobic systems to be maintained, and most counties (Lubbock included) expect either a maintenance contract with a licensed provider or documented homeowner maintenance where allowed.
Don't unplug it and hope. The alarm usually means high water in the pump tank or a failed air compressor. High water can be a pump failure, a float switch problem, or simply too much water entering the system too fast. Left alone, untreated water either backs up toward the house or gets sprayed untreated onto your lawn.
A properly working aerobic system smells earthy at worst. A rotten-egg smell means the aerator isn't running — the bacteria that digest waste die off within days without air, and the system reverts to an anaerobic (smelly, under-treating) state.
Spray events are typically timed for pre-dawn hours. Daytime spraying, constant spraying, or no spraying for weeks all point to timer, float, or pump problems worth a service call before they become tank problems.
Extremely common on acreage properties that changed hands. If you've bought a home with an aerobic system and have no service records, a baseline inspection plus pump-out tells you exactly what you own and resets the maintenance clock.
Typical price ranges: routine maintenance visits run $100–$200, annual maintenance agreements (usually 2–3 visits per year) run $250–$400, pump-outs of aerobic tanks run $350–$550 depending on configuration, and component repairs are quoted up front after diagnosis. You'll always know the number before work starts.
Request Aerobic ServiceTCEQ rules require aerobic systems to be maintained and checked regularly. Many counties require a contract with a licensed maintenance provider, while some allow homeowners to self-maintain after the initial period if they meet requirements. We'll tell you exactly what applies to your county and keep the documentation straight either way.
Properly treated aerobic effluent has little odor. A sewage smell during spray events usually means the aerator is down or the chlorinator is empty — both fixable, and both worth fixing quickly since untreated spray is a health issue.
No. Pool tablets (trichlor) are chemically different from septic tablets (calcium hypochlorite) and can create dangerous conditions in a septic chlorinator, including explosive gas buildup. Only use tablets labeled for wastewater/septic use.
Air compressors typically run 3–8 years, submersible pumps 5–10, and spray heads take regular abuse from mowers and West Texas sun. Budgeting a few hundred dollars every few years for components is normal ownership cost — catching failures early at maintenance visits keeps them from becoming tank problems.
