Aerobic Septic Installation in Sisterdale, TX

Building on acreage with no sewer? We design, permit and install a TCEQ-licensed aerobic system sized for your Kendall County lot, and start the required maintenance from day one.

Aerobic Install in Sisterdale

A huge share of new construction in Kendall County is on acreage with no sewer line anywhere near it, and on Hill Country ground that means an aerobic system is the only viable answer. We design, permit and install complete aerobic treatment units (ATUs) across the county, from the subdivisions filling in along I-10 and Highway 46 outside Boerne to custom homes on raw land toward Kendalia, Sisterdale and Comfort, and the large lots in Cordillera Ranch and Tapatio Springs. A proper install starts with a site evaluation and soil analysis, then a system sized to the home and approved by Kendall County, set with the trash tank, aeration chamber and pump tank, the compressor and electrical controls, the chlorination, and the spray distribution laid out to cover the required area without hitting the house, the well or the property line. We are licensed installers who do it by the book: the right design, the right permit, an inspection that passes the first time, and a system that will run clean for decades if it is maintained.

Aerobic Septic Installation in Sisterdale, TX

Septic service in Sisterdale

Sisterdale is the small settlement on FM 1376 between Boerne and Luckenbach, a dance hall, a winery and ranch country along Sister Creek in the northern part of Kendall County. Homes here are spread out on acreage, old ranch houses alongside newer custom builds, and all of them are on septic with no sewer anywhere in reach. The newer homes and any rebuilt system run on aerobic units because the creek-bottom clay and the limestone on the hills do not percolate. We hold maintenance contracts, repair compressors and pumps, inspect systems for sales and install new units across the Sisterdale area and out FM 473 toward Comfort. Sisterdale is a long drive from most septic companies, so systems here are often overdue: a compressor that quit months ago, a chlorinator empty since last year, a contract that lapsed when a ranch changed hands. We make the drive on a schedule, and we bring the common parts so a four-month visit does not turn into two trips.

Common Septic Problems in Sisterdale

The aerobic system problems we see most around here, and how we handle them.

Systems that go unserviced because of the distance

Sisterdale is far enough from Boerne and Fredericksburg that maintenance visits get skipped and problems sit. A dead compressor left for months stops treatment entirely and sends poor effluent to the field. We schedule the four-month visits and show up for them, so a Sisterdale system is maintained like one in town.

Creek-bottom clay and hillside limestone

Lots along Sister Creek sit on tight clay that holds water; lots on the hills sit on shallow limestone with no soil to speak of. Both are hard on spray fields, and both are why new systems here are aerobic. Design to the actual ground and regular maintenance keep a field dispersing.

Ranch sales with no contract on record

When a Sisterdale ranch or homestead sells, the septic system often has no maintenance history at all. A buyer needs an inspection to know what they are getting and a contract in their name to be compliant with Kendall County. We do both and put the findings in writing for the deal.

Aerobic Install in Sisterdale: FAQs

Do you really come out to Sisterdale?
Yes, on a schedule. We cover Sisterdale, FM 1376, Sister Creek and the acreage out FM 473 toward Comfort. We carry the common aerobic parts so a maintenance visit or a repair is usually finished in one trip.
My compressor has been dead for a while. Is the system ruined?
Usually not, but it needs attention now. Without the compressor the treatment bacteria die off and poorly treated effluent goes to the spray field, which can clog it over time. We replace the compressor, check the chlorinator and the field, and get the system treating again; the sooner the better.
We are buying acreage near Sisterdale with an existing septic system. Can you inspect it?
Yes. We open the tanks, test the compressor, pump, floats and alarm, run the spray cycle, walk the field and confirm whether Kendall County has a contract on record. You get a written summary inside your option period, and we set up the contract in your name once you close.
How long does a new aerobic system installation take?
Once the site evaluation, design and permit are in hand, the physical install of a typical residential aerobic system usually takes a few days, plus time for the county inspection and final hookup. The biggest variable is permitting and soil work up front, so the sooner we start the evaluation, the sooner you can be running.
What determines the size and cost of my system?
Mainly the number of bedrooms, which sets the design wastewater flow, plus your soil and how much area you have for spray distribution. Tighter soils or limited yard space can require a larger pump tank or drip distribution. We do the site evaluation first so you get a system sized correctly for your home and a real price, not a guess.
Do I have to maintain a brand-new system right away?
Yes. Texas requires an aerobic system to be under a maintenance contract from installation, including the standard two-year initial maintenance period and inspections every four months. We start that contract at install and keep your reports filed with Kendall County, so you are compliant from day one.
