Aerobic systems

Aerobic septic maintenance in Bandera County

If you own an aerobic septic system in Texas, keeping it under a maintenance contract is not optional. The state requires it to be inspected three times a year by a licensed maintenance provider, and a contract to cover that runs about $300 to $600 a year. This is the service most Bandera County properties actually need, and this page explains what the law wants, what a contract covers, and why letting it lapse turns into a real problem.

Why Texas requires aerobic maintenance

An aerobic system is not a plain tank in the ground, it is a small sewage treatment plant. It pumps air into the waste so bacteria break it down, then it disinfects the treated water and sprays it across your yard through sprinkler heads. Because it is actively treating and then discharging water onto the surface, the state treats it as machinery that has to be watched, not a tank that can be forgotten. That is why Texas requires an aerobic system to be inspected three times a year by a licensed maintenance provider for as long as you own it.

The reason bites harder in Bandera County than most places. This is limestone country, thin soil over fractured rock, and that rock is exactly why so many properties here run aerobic in the first place. Water does not filter down through limestone, it runs through the cracks and can carry poorly treated effluent straight toward the groundwater that every well in the county draws from. The maintenance is what keeps a system actually treating the water before it sprays out, which is the whole point of putting an aerobic system on rocky ground to begin with.

Bandera County's two-year contract on new installs

When a new aerobic system goes in anywhere in Bandera County, it comes with a mandatory two-year maintenance contract from the start. That is a county rule, not a sales tactic, and it means the system is under professional maintenance from day one through its first couple of years, which is when a lot of setup and break-in issues surface. Buyers of newer homes sometimes do not realize this contract exists until it is about to expire and they have to arrange their own. When that initial two years is up, the requirement to maintain the system does not end. You still need three inspections a year, so you carry it forward with a new contract of your own rather than letting the system go unmaintained.

What a maintenance contract covers

A maintenance visit is a real inspection of every working part of the system, not a quick look. Across the three visits a year, a licensed provider checks the pieces that keep the system treating water and catches the ones about to fail while they are still cheap to deal with.

The air pump

The air pump is the heart of the system. It pushes air into the treatment chamber so the bacteria that break down the waste can live. If it quits, treatment stops within a day or two and the whole system goes bad, so the maintenance check makes sure it is running, moving air, and not on its way out. A pump caught wheezing on an inspection is a planned replacement. A pump found dead after the fact is an emergency with a wet yard attached.

Chlorine and the chlorinator

Before the treated water sprays onto your yard it has to be disinfected, and most systems do that with chlorine tablets in a chlorinator tube. The provider checks that the chlorinator is working and that the tablet supply has not run dry, because a system spraying undisinfected water is a health problem and a violation even if everything else is working.

Spray heads and the field

The system disposes of the treated water through sprinkler heads across a designated spray field. The provider checks that the heads are unbroken and not clogged, that they are actually distributing water, and that the field is not staying wet or pooling, which would point to a head problem or the system pushing out water it has not treated well.

Control panel, alarm, and effluent quality

The control panel runs the system and drives the alarm that warns you when something is wrong, so the provider makes sure the panel and the alarm both work. They also look at the quality of the treated water itself, clarity and smell, because that is the real test of whether the system is doing its job. If the effluent looks or smells wrong, something upstream needs attention before it reaches your yard.

Getting the chlorine right matters

This is worth saying plainly because getting it wrong is dangerous. An aerobic septic system uses calcium hypochlorite tablets, the kind sold for wastewater and septic disinfection, not the tablets you drop in a swimming pool. Pool tablets are usually a different chemistry, trichlor, and putting them in a septic chlorinator can create a dangerous reaction and gases, and they do not disinfect septic effluent the way they are supposed to. Pool chlorine and septic chlorine are not interchangeable, whatever the price at the store suggests. A maintenance provider stocks and uses the correct septic tablets, which is one more reason to let the contract handle it rather than guessing in the aisle.

The alarm and what it means

Every aerobic system has an alarm, usually a red light and a buzzer on the control panel, and it exists to tell you something needs attention before the yard tells you. It most often means a failed air pump, a tripped breaker, or a high water level in the tank. It is not always a middle-of-the-night emergency, but it is never nothing. Silence the buzzer if there is a button for it, ease up on water use, and call. The worst thing you can do is ignore it for a month, because a beeping alarm is the cheap warning, and the wet yard that follows is the expensive one. What the alarm is pointing at is usually a repair the aerobic repair page covers.

Why letting it lapse is a real problem

People sometimes treat the $300 to $600 a year as a tax to dodge, and it is worth understanding what the money actually prevents. An aerobic system that is not maintained does not quietly keep working. The chlorinator runs empty, the air pump eventually quits, the treatment stops, and the system starts spraying poorly treated sewage across your yard. That is three problems at once. It is a health hazard for anyone in that yard, it is a code violation the county can act on, and it is a repair or a component replacement that costs far more than the contract you skipped. The whole logic of the contract is that somebody is looking at the system three times a year and catching the small failure before it becomes the big one. On these systems a part caught early is a service call, and the same part ignored is a wet, smelly yard and a notice from the county. The cost page lays the numbers side by side, and the contract is the cheap side every time.
