Aerobic Septic Maintenance Contracts in the Hill Country

Aerobic treatment units, often called ATUs or aerobic septic systems, are everywhere in the Texas Hill Country. On lots with thin soil, rock, or slopes, a conventional drain field often can't be permitted, so many homes use an aerobic system instead. These systems pump air into the wastewater so oxygen-loving bacteria can break it down more completely, then disinfect the treated water and disperse it, most often through spray heads in the yard.

That extra treatment comes with extra moving parts and extra rules. Hill Country Septic Pumping connects homeowners in Boerne, Bulverde, Spring Branch, Canyon Lake, New Braunfels, Fair Oaks Ranch, Helotes, and nearby areas with independent local providers who offer aerobic maintenance contracts.

Texas Rules for Aerobic Systems

Aerobic systems in Texas are regulated as on-site sewage facilities (OSSFs) under TCEQ rules in Title 30, Texas Administrative Code, Chapter 285, and are often administered locally by county or other authorized agents. Key points homeowners should know:

• Initial maintenance contract. When a new aerobic system is installed, an initial two-year service policy is required, starting when the system is first used (for a new home, generally the builder's sale date).
• Ongoing maintenance. After the initial period, the owner generally must keep the system maintained, either by renewing a contract with a qualified maintenance provider or, where the local permitting authority allows it, by meeting the requirements to maintain the system themselves.
• Routine inspections. Maintenance contracts typically include inspections three times per year, about every four months.
• Reporting. Under TCEQ rules, the maintenance provider must be TCEQ-licensed and submit reports to the permitting authority and the owner at least once every four months (every six months for some electronically monitored systems).

Rules can differ by county, so check with your local permitting office (for example, the county that issued your OSSF permit) for exact requirements on your property.

What a Maintenance Visit Usually Includes

Each provider has its own checklist, but a typical routine visit covers:

• Checking the aerator or air compressor and diffusers
• Testing the alarm and control panel
• Inspecting the pumps, floats, and timer
• Checking the chlorinator or disinfection unit and chlorine level
• Inspecting spray heads or the dispersal area
• Measuring sludge levels to determine if pumping is needed
• Recording findings and filing required reports

Ask what is covered in the contract price and what counts as extra, such as parts, chlorine, pumping, or emergency calls.

Signs Your Aerobic System Needs Attention

• Alarm light or buzzer. This often means a high water level or air compressor failure.
• Strong odor. A properly running aerobic system shouldn't smell strongly of sewage.
• Spray heads not running at their scheduled time, or spraying cloudy or smelly water.
• Compressor silent or noisy. No hum, or a grinding sound, can mean failure.
• Soggy areas around the spray field.

Don't simply silence an alarm and forget it. Contact a maintenance provider.

Why a Contract Makes Sense

• Keeps you aligned with local OSSF requirements
• Catches small part failures before they turn into big repairs
• Many contracts include priority scheduling or discounts on repairs and pumping (terms vary by provider)
• Gives you a written service history, which helps when selling the home

Buying a Home With an Aerobic System?

Ask the seller for the OSSF permit, the current maintenance contract, and recent inspection reports. Transfer or set up a new contract after closing. See our septic inspections page for more.

Aerobic Maintenance FAQ

Can I maintain my own aerobic system? TCEQ allows homeowner maintenance after the initial two years for many systems, but some local permitting authorities require training or prohibit it. Check with your county or local permitting authority.

How many visits are in a contract? Typically three per year. Confirm with the provider.

Do I have to add chlorine? If your system uses a tablet chlorinator, the chlorine supply needs to be kept up. Use tablets made for wastewater, not pool tablets, unless your provider says otherwise.

What if my contract lapses? Your permitting authority may require proof of maintenance. Get a new contract set up as soon as you can.

Can you switch my provider? We can connect you with another local provider. Review your existing contract's terms first.
