Aerobic Septic Service in Tyler & Longview, TX

Last reviewed November 9, 2026

What makes an aerobic system different

A conventional septic tank treats wastewater with oxygen-free (anaerobic) bacteria, then relies on a drain field to finish the job. An aerobic treatment unit (ATU) adds an aerator that pumps oxygen into the tank, which speeds up and improves the bacterial breakdown of waste. Aerobic system maintenance is more involved than a conventional tank’s, and homes around Longview and the rest of Gregg and Harrison counties follow the same Texas rules described below. The more thoroughly treated effluent then typically goes to a smaller spray field or drip system rather than a full-size conventional drain field.

That’s why aerobic systems are common on East Texas lots with tight space or poor, shallow or clay-heavy soil that can’t support a standard drain field. The tradeoff is a more complex system with moving parts (aerator, pump, spray heads, alarm) that a conventional tank doesn’t have, and a maintenance obligation that Texas takes seriously. If you are in Tyler, see aerobic septic service in Tyler, TX; around Longview, the same rules apply, covered on the Longview service page.

Texas maintenance contract rules

The Texas Commission on Environmental Quality (TCEQ), which regulates septic systems (On-Site Sewage Facilities, or OSSFs) under 30 TAC Chapter 285, requires licensed maintenance for aerobic treatment units, at least for the first two years. Texas only approves aerobic treatment units that are tested and listed as Class I systems under NSF Standard 40 (30 TAC 285.32). Here’s what that means in practice:

A maintenance contract is required when the system is new. A licensed maintenance provider inspects and services the system on a set schedule.
Inspection and reporting happen regularly. The maintenance company checks system components at every visit and must report results to the permitting authority and the owner at least once every 4 months (this interval can extend to about every 6 months where the system has electronic/telemetry monitoring in place).
After 2 years, self-maintenance may become an option. TCEQ rules allow a homeowner to perform their own maintenance on certain systems starting 2 years after the aerobic unit’s initial installation. Many owners keep a professional service agreement anyway, since it also covers troubleshooting alarms and mechanical failures.
Your specific permit may set stricter terms. Local permitting authorities can require conditions beyond the state minimum, so check your permit paperwork or ask the maintenance company what your contract specifically requires.

Texas A&M AgriLife Extension runs an on-site sewage facility (OSSF) education program with homeowner-focused courses and guides on operating and maintaining an aerobic system, useful reading alongside your maintenance company’s advice.

Our aerobic maintenance contract guide covers the two-year rule, visit schedule and doing your own upkeep.

Chlorine disinfection: use the right tablets

Aerobic systems disinfect treated effluent with chlorine before it’s sprayed or discharged. TCEQ’s guidance is specific and worth following exactly:

Use a chlorine tablet made from calcium hypochlorite that is EPA-certified for wastewater disinfection.
Never use swimming pool chlorine tablets. Pool tablets are typically made from trichloroisocyanuric acid, which dissolves too quickly for a septic disinfection chamber and can release nitrogen trichloride gas, creating a real explosion hazard.

If you’re not sure what’s in your chlorinator, ask the maintenance company to check it at your next visit rather than guessing.

Alarms, spray heads and what they’re telling you

Each component in an aerobic system has one job, and knowing what a failure looks like helps you describe the problem accurately when you reach out.

Component	What it does	What a problem looks like
Alarm / warning light	Signals high water level, pump failure or electrical fault	Steady or flashing light, audible alarm
Aerator	Pumps oxygen into the tank for bacterial treatment	Unusual noise, no visible bubbling, tank odor
Spray heads	Distribute treated, disinfected effluent over the spray field	Heads not popping up, uneven or no spray, spray running constantly
Chlorinator	Holds and dissolves disinfection tablets	Empty of tablets, or tablets dissolving unusually fast

If the alarm sounds, check the breaker first since a tripped breaker is a common, simple cause. If resetting it doesn’t clear the alarm, or the alarm keeps returning, that calls for a service visit rather than repeated resets.

Signs of an aerobic system problem

A handful of warning signs point to a mechanical or maintenance issue rather than a routine check:

Alarm or warning light active
Sewage odor near the tank or spray field
Sprinkler heads not running, or running constantly
Wet or spongy ground around the spray field
Discolored or unusually green grass over the spray field

What does an aerobic system cost?

Aerobic systems cost more than conventional systems both to install and to maintain, because of the added mechanical components and the required service agreement. A new conventional system runs about $3,500 to $8,500 per HomeGuide, while an aerobic system runs $10,000 to $20,000 per HomeAdvisor.

	Conventional	Aerobic treatment unit
Installation cost	$3,500 to $8,500	$10,000 to $20,000
Ongoing maintenance	Pumping every 3 to 5 years	Licensed contract for the first 2 years, then a contract or owner upkeep where the county allows it
Moving parts	None	Aerator, pump, spray heads, alarm

See septic installation for the full Texas permit process that applies to a new aerobic system, and septic tank pumping if your household has a conventional tank instead.

Why East Texas lots often end up with aerobic systems

Soil across parts of Smith, Gregg and the surrounding counties can be shallow, clay-heavy or slow-draining in spots, conditions that don’t always support the larger drain field a conventional system needs. A site evaluation is what actually determines whether your lot qualifies for a conventional system or requires an aerobic one; see septic installation for how that evaluation and the Texas permit process work together.

Choosing a maintenance provider

Since Texas requires licensed maintenance at least for the first two years, it’s worth choosing one you can rely on for more than the minimum. Ask whether they’ll proactively flag component wear (not just confirm the system is running), how quickly they respond to an alarm call outside a scheduled visit, and whether their reports go to you directly and promptly, not just to the maintenance company’s file for the permitting authority.

What a typical 4-month visit covers

A standard visit works through the same checklist every time so nothing gets missed:

Checking the aerator for proper operation and unusual noise
Verifying chlorine tablets are the correct type and adequately stocked
Testing sprinkler heads for even distribution across the field
Confirming the alarm and float switch respond correctly
Measuring sludge depth to flag whether pumping will be needed soon
Filing the required report with the permitting authority and providing you a copy

Keeping your system in good standing

Staying current on your service agreement does more than satisfy Texas rules. It’s how component wear, chlorinator issues and early signs of failure get caught before they turn into an alarm going off at an inconvenient hour. If your aerobic system needs service, an inspection, or you’re not sure your maintenance contract is up to date, request a call back.

Common questions

What are the disadvantages of an aerobic septic system?

Aerobic treatment units cost more to install than conventional systems, generally $10,000 to $20,000 versus $3,500 to $8,500 per HomeAdvisor and HomeGuide, and they require ongoing electricity to run the aerator and pump. They also carry a mandatory service agreement requirement in Texas that a conventional tank doesn't have, so there's an ongoing cost a conventional system owner doesn't face.

Do aerobic septic systems need to be pumped out?

Yes, though less predictably than a conventional tank. Pumping frequency for an aerobic system depends on sludge depth and the manufacturer's specifications rather than a flat 3-to-5-year rule. Your licensed maintenance provider checks sludge levels at each visit and will tell you when pumping is due.

Which is better, a conventional or aerobic septic system?

Neither is universally better; it depends on your lot. Conventional systems need more land and specific soil conditions but cost less and don't require a service agreement. Aerobic systems work on smaller lots and poorer soil because they treat waste more thoroughly before it reaches a (typically smaller) spray field, but cost more upfront and need licensed maintenance, at least for the first two years.

Can you flush toilet paper in an aerobic septic system?

Standard toilet paper is fine in any septic system, aerobic or conventional. What to avoid is the same in both: wipes (including ones labeled flushable), grease, feminine hygiene products and other material that doesn't break down, since these can clog pumps and components that are more sensitive in an aerobic unit.

What is the average lifespan of an aerobic septic system?

The tank itself can last many years with proper maintenance, but the mechanical components (aerator, pump, spray heads) wear out faster than a conventional tank's passive design and need periodic replacement. Staying current on your required maintenance visits is what catches component wear before it causes a failure.

Why is the red light or alarm on my aerobic system going off?

An alarm usually signals a problem with the pump, aerator or float switch, such as high water level in the tank or a component that has lost power or failed. Check the breaker first, since a tripped breaker is a common and simple cause, but don't ignore a persistent alarm. Request service if resetting the breaker doesn't clear it.
