Aerobic Septic Maintenance in Henly, TX

Plenty of newer Henly homes were built on thin, rocky soil where a standard tank and trench would not pass permitting, so an aerobic treatment unit, or ATU, was installed instead. An ATU uses an air pump to feed oxygen to bacteria, then disinfects the water and sprays or drips it over the yard. It works well, but only when someone looks after it. Texas requires a maintenance contract for aerobic systems, and Hays County requires an initial two-year contract on new ones. The system is also a good reason to keep your own simple log. Write the date of each visit, what was replaced and whether the alarm ever sounded. That log becomes useful when you sell, since a buyer will want proof of care.

A maintenance visit follows the same path the water takes. We check the pretreatment tank, the aeration chamber, the clarifier and the pump tank. We test the alarm, confirm the compressor is moving air, inspect the disinfection stage and make sure spray heads are covering the intended area. In Henly, where the spray field often sits on a slope above a pasture or creek draw, we also look at whether water is traveling off the field. Between visits, you can do part of the work yourself. Look at the alarm light, listen for the air pump humming, and walk the spray area to see whether the grass is evenly wet or oddly soggy. If anything looks off, make a note and tell us at the next visit or sooner.

After the first two years, Hays County requires the owner to have a new maintenance contract in place at least 30 days before the old one ends. The county also lets a trained owner service a single-family system after completing its coursework, but most homeowners here choose a licensed provider because the work is technical. If you bought a Henly property with an aerobic system, ask for the permit file and the last service report right away. Be careful about what goes down the drain. Bleach in large amounts, antibacterial products, wipes and grease all damage the bacteria an ATU depends on. Small habits like these keep the unit calmer between service dates.

A routine visit follows a set pattern. The technician checks the control panel and alarm, the air pump and its filter, the aeration chamber, the clarifier and the disinfection unit. In most systems, disinfection uses chlorine tablets that must be replaced as they dissolve. The technician also looks at the spray heads or drip lines to be sure the water spreads evenly and does not pool or run off the property. The state rule calls for a weather-resistant tag on the system that is marked with the date of each check. When the visit ends, the technician finishes a report that goes to you and to the permitting authority, and you should keep your copy with your other septic records.

Some of the best maintenance happens between visits. Listen for the air pump, which should hum steadily. Walk the spray area now and then and look for matted grass, dead patches, pooling or odors. Keep the control panel dry and the breaker on. Do not shut off the system when you travel, because the bacteria need air to stay alive. If an alarm sounds, silence it, note the time and call for service. Go easy on bleach, antibacterial cleaners and drain openers, which can harm the bacteria. Watch what goes down the drain too. Grease, wipes, cat litter and coffee grounds do not belong in any septic system, and an aerobic unit is no exception to that rule. A few minutes of attention each month can head off a service call and keep your reports clean.

Weather out here is wide open. Summer drought bakes the ground, cracks clay and dries spray fields, while a single big storm can drop several inches of rain onto thin soil that has no place to hold it. After a storm, low spots in a field can stay wet for days. Wind and lightning are real concerns for aerobic systems, since a power surge can damage the control panel or air pump, and a power outage stops treatment until the electricity is restored. Livestock and ranch vehicles add risk, because heavy loads on a field compress soil and crush shallow lines. Roots from cedar and oak will find their way into pipes if allowed. A seasonal walk around the field, lids and panel catches most problems early. Long gravel drives also need planning for service: a heavy pump truck needs firm ground and room to turn, so scheduling after a dry stretch helps. Flag your tank lids ahead of time, and tell us if you are unsure where the tank is.
