Is a maintenance contract required for an aerobic septic system in Texas?

 

Yes. Every new aerobic system in Texas comes with a two-year initial service policy, and after that the owner must either sign a new maintenance contract with a licensed maintenance provider or, where the county allows it, maintain the system themselves.

 

These rules come from the Texas Commission on Environmental Quality (TCEQ) under 30 TAC Chapter 285. A copy of each signed contract has to be sent to your county's permitting authority at least 30 days before the current one expires. Harris County says failing to submit a contract can lead to misdemeanor charges in Justice of the Peace court. Greywater offers yearly maintenance contracts across Montgomery, Waller, Harris, and Grimes counties.

 

How often does my aerobic septic system need to be inspected?

 

In most of Texas, a licensed provider must inspect and report on an aerobic system at least once every four months (three times a year). In Harris County, residential aerobic systems must be inspected at least once every three months (four times a year).

 

The four-month minimum is set by TCEQ, and each report must be filed with the county and the owner within 14 days of the visit. Harris County sets the stricter three-month schedule for residential systems. That's why Greywater visits every four months in Montgomery, Waller, and Grimes counties and every three months in Harris County, including Tomball, Spring, and Cypress addresses in Harris County. If you're not sure which county permits your system, check your permit or give us a call.

 

What does a red or yellow light on my aerobic septic control panel mean?

 

A red or yellow light (or a buzzing alarm) on your aerobic panel means the system has detected a problem, most often a high water level or low air pressure, and it needs to be checked.

 

High water can be caused by a failed water pump, clogged spray heads or filters, or more water going in than the system can handle. Low air usually points to a broken air pump, a broken air line, or a low water level in the aeration chamber. Exactly what each light means depends on your system's brand and panel. Until it's checked, cut back on water use (laundry, long showers, dishwasher), then call us at (832) 530-5945. Our trucks carry parts for most brands.

 

How often should an aerobic septic tank be pumped?

 

It depends on how much sludge builds up and on your manufacturer's recommendations. As a rule of thumb, the trash (pretreatment) tank on many aerobic systems needs pumping about every 2 to 3 years.

 

TCEQ says pumping for aerobic units should be based on sludge depth and the manufacturer's guidance, not a fixed calendar. Texas A&M AgriLife Extension recommends checking solids in the aeration chamber too. Heavy use of a garbage disposal, grease down the drain, or a full household can shorten the time between pumpings. Greywater doesn't pump tanks ourselves, but if your system needs pumping, we're happy to recommend a pumping company we trust.

 

Why does my aerobic septic system smell?

 

A healthy aerobic system should have little to no sewage odor, so a bad smell usually means the system isn't getting enough air or is overloaded.

 

Common causes include a failed or weak air pump, clogged air diffusers, an empty chlorinator, or too much grease, food waste, harsh cleaners, or water going down the drains. For some brands, clogged diffusers that haven't been replaced on schedule lead to poor aeration and foul odor. Greywater can check the air pump, air lines, and diffusers and tell you what's causing the smell.

 

What's included in a Greywater aerobic maintenance visit?

 

A licensed Greywater technician inspects your whole aerobic system, makes most needed repairs on the spot, and leaves a written maintenance report.

 

Our technicians wear clearly labeled Greywater work shirts and knock on your front door when they arrive. Each visit is recorded on a dated blue decal on or near your control panel, and the maintenance report lists everything that was checked and any repairs needed. Our trucks are fully stocked with parts, so about 95% of the time we can fix problems right away instead of waiting weeks to order parts.

 

Which aerobic septic system brands do you service?

 

Greywater services most major aerobic septic brands, including AquaKlear, Aqua Safe, Cajun Aire, Clearstream, Delta Whitewater, Hoot, Hydro Action, Pro Flo, and Southern.

 

If your brand isn't listed, give us a call at (832) 530-5945. We work on many other systems too. We service homes in Tomball, Magnolia, the FM 1488 area, Conroe, Willis, Montgomery, Spring, Cypress, and nearby communities.

 

Do I need an aerobic septic inspection when buying a home?

 

Yes, we strongly recommend one. Don't buy a home with an aerobic septic system without having it checked by a licensed professional, because problems aren't always visible and the system's permit transfers to you as the new owner.

 

For a Greywater home-buyer inspection, we pull the installation drawing from the county to make sure the system was built to code. We check the spray heads' location, type, and number against that drawing, and we inspect all electrical components, pumps, filters, and lines. If the home is sold during the system's initial two-year service policy, Texas rules say that policy carries over to the new owner. Otherwise, plan to sign a maintenance contract right after closing.

 

What causes an aerobic septic air pump to fail?

 

Most air pump failures in aerobic systems happen when the rubber bladders (diaphragms) inside a linear air pump tear, or when clogged diffusers make the pump work too hard.

 

On a linear air pump, a safety screw is designed to break when the bladders tear, which shuts the pump down before the motor is damaged. In those cases the pump can usually be rebuilt instead of replaced. If the safety screw doesn't break, the pump keeps running, overheats, and can be ruined. Clogged diffusers raise back pressure on the pump, and some brands need diffusers replaced on a routine schedule. Greywater rebuilds and replaces air compressors and replaces diffusers.

 

Do you offer same-day or emergency aerobic septic repairs?

 

Yes, in most cases. Our trucks are fully stocked with parts, so about 95% of the time our technicians can repair your system on the first visit. We also take emergency calls on Saturdays.

 

Our regular hours are Monday through Friday, 8:00 AM to 5:00 PM, with Saturdays reserved for emergency calls only. We repair air compressors, water pumps and pump screens, spray heads and spray lines, electrical parts (photo eyes, timers, control panels), air lines, and diffusers, and we install new risers and lids. If you have an alarm or a red or yellow light, call (832) 530-5945.

 

Can I maintain my own aerobic septic system in Texas?

 

Sometimes. State rules let the owner of a single-family home maintain their own aerobic system after the initial two-year service policy ends, but many counties restrict or prohibit this, so check with your county first.

 

Self-maintenance is never allowed for commercial, multifamily, or speculative residential property. Some counties require approved training, such as Texas A&M AgriLife's online course, and Harris County's testing acknowledgment form requires owners to employ a licensed operator for the life of the system. Whoever maintains the system, keep the chlorinator stocked with calcium hypochlorite tablets labeled for wastewater disinfection. Never use swimming pool tablets, which TCEQ warns don't disinfect properly and can release an explosive gas. If you'd rather not handle the inspections, testing, and county reporting yourself, Greywater can take it off your plate.
