About Aerobic Septic Maintenance
An aerobic septic system — an aerobic treatment unit, or ATU — isn't a pump-it-every-few-years-and-forget-it system. It runs an air pump to keep oxygen-loving bacteria working, and most systems disinfect the treated water (often with chlorine tablets) before it's sprayed or dripped onto the yard. That means moving parts, alarms, and a chemical supply that all need regular attention. When an aerator quits or the chlorinator runs dry, the system keeps discharging — just not properly treated water.
In Texas, every new aerobic system comes with a two-year maintenance policy that starts when the system is first used. After that, a single-family homeowner either keeps a contract with a TCEQ-licensed maintenance provider or, where local rules allow, maintains the system personally; commercial, multifamily, and speculative-residential owners must keep a contract. Under contract, the system is checked and tested on a schedule, with a report to your permitting authority every four months — every six months with electronic monitoring.
Local rules can be stricter than the state's. Some Texas counties require a contract for every aerobic system or allow owner maintenance only after an approved class — Bell County, for example, limits self-maintenance to owner-occupants who complete district-approved training. Check with your county or city permitting office before letting a contract lapse.
We connect aerobic system owners with independent local maintenance providers, who handle their own licensing, contracts, and the reports your permitting authority expects.
Common Jobs We Route
- Maintenance contracts for new owners when the installer's two-year policy ends
- Contract renewals — in Texas, filed with the permitting authority at least 30 days before the current one expires
- Replacement contracts when a provider drops a contract (Texas owners have 30 days to file a new one)
- Contracts for buyers taking over an aerobic system after a home sale
- Alarm calls: aerator or pump failures and high-water alarms
- Chlorinator checks and tablet refills
- Spray-head, timer, and float-switch problems
- Trash-tank pumping — AgriLife suggests about every 2 to 3 years
What Affects the Price
Providers quote their own work — these are the factors that consistently move the number.
- Visit and test frequency — three tested visits a year, or two with electronic monitoring
- Chlorine — whether tablets are included or you buy and add them yourself (many contracts leave refills to the homeowner)
- Parts and repairs — whether any are included; Texas rules put repairs on the owner unless the contract says otherwise
- The complaint response time the contract promises
- Whether trash-tank pumping is included or billed separately
- Local permitting-office fees on contracts, where a county charges them (Bell County: $20 per contract year to verify a contract)
How It Works
- Step 1
Tell us about your system
County, system type (spray or drip), whether you're still inside the two-year policy, and any alarm or problem.
- Step 2
Matched to a maintenance provider
Requests route to independent local pros who handle aerobic systems.
- Step 3
Compare contract terms, not just price
Items covered, visits per year, chlorine, parts, and the response time every Texas contract must state.
- Step 4
Contract filed, visits scheduled
Where required, the provider files the contract and test reports with your permitting authority and punches the tag on your control panel at each visit.
Aerobic Septic Maintenance FAQs
Do I have to have a maintenance contract for an aerobic septic system in Texas?
For the first two years, yes. Every new aerobic system comes with a two-year service policy. After that, a single-family homeowner can renew the contract or maintain the system personally, unless local rules require a contract. Commercial and multifamily owners must keep a contract.
How often does an aerobic septic system get inspected in Texas?
Under contract, it's tested and reported to the permitting authority every four months, or every six months with electronic monitoring. Each report is due within 14 days.
What does a Texas aerobic maintenance contract have to include?
At a minimum: every item the contract covers, the complaint response time, the provider's name, how often routine maintenance and testing/reporting happen, and who maintains the disinfection unit (chlorinator). Compare contracts on those terms.
Does a maintenance contract cover repairs?
Not automatically. The provider must inspect, test, and report, but Texas guidance puts repairs on the owner. Check the contract's list of covered items.
Can I maintain my own aerobic system?
In Texas, a single-family owner may self-maintain after the initial two-year policy, and self-maintainers aren't on the four-month reporting schedule. Local authorities can require training or prohibit self-maintenance. AgriLife's online homeowner course counts only in counties that have approved it.
Can I use pool chlorine tablets in my aerobic system?
No. TCEQ says to use only calcium hypochlorite tablets made for wastewater treatment, never pool tablets.
Does an aerobic system still need pumping?
Yes. Routine maintenance visits don't remove solids. AgriLife suggests pumping the trash tank on a schedule like a septic tank's, about every 2 to 3 years. TCEQ says the right interval depends on sludge depth and the manufacturer.
What happens to the maintenance contract when I buy a house with an aerobic system?
If the home sells during the first two years, the initial policy transfers to the buyer. After that, check local rules. Bell County, for example, requires a maintenance contract within 30 days of the sale, along with a permit transfer.
Why does my aerobic system struggle at a weekend lake house?
The bacteria need a steady food supply. AgriLife notes that two weeks away followed by 10 loads of laundry can flush out what's left. After a quiet stretch, spread out laundry and heavy water use.
