Service · Aerobic Septic Systems

Aerobic septic systems, properly designed and installed.

When the soil or the lot rules out a conventional system, aerobic is the answer. We design it for your specific site conditions, handle county permitting, and install it under a single TCEQ license, so you get one accountable team instead of multiple contractors passing the problem around.

What We Install

Not every site can handle a conventional system

Aerobic treatment units process wastewater to a higher standard before it reaches the soil, which is why they work on sites where conventional drainfields would fail or never receive permit approval. Dense clay, limited land, steep terrain, and proximity to wells or waterways all push a site toward aerobic treatment.

We install aerobic systems across Austin and the Texas Hill Country, where the soil varies dramatically from one property to the next. Hill Country limestone and cedar-heavy clay are not forgiving. A site that looks workable from the road can fail a standard perc test. When that happens, aerobic is not a fallback plan, it is the designed solution, and the design has to be right.

Our TCEQ license covers both the design and the installation, which means the engineer who evaluated your soil is also accountable for what goes in the ground. That continuity matters when you are dealing with county inspectors and long-term system performance.

What an aerobic install includes

  • Soil and site evaluation to confirm aerobic is required or optimal
  • Aerobic treatment unit sizing and system design with CAD plans
  • County OSSF permit filing and follow-through to approval
  • ATU tank set, aeration, chlorination, and spray or drip field installation
  • Electrical connection to the ATU control panel
  • Clean excavation and site restoration
  • Final county inspection, walked on your behalf
  • Guidance on mandatory maintenance contract requirements

Why aerobic costs more

Aerobic systems have moving parts, a control panel, a chlorination system, and a spray or drip dispersal field. Texas also requires an active maintenance contract for the life of the system. We explain the full cost picture before you commit so there are no surprises after installation.

How It Goes

From site evaluation to working system

1

Site Evaluation

Soil profiling, slope assessment, setbacks, and water-table check to confirm what your site can support and which aerobic components fit.

2

System Design & Permit

We size the ATU, design the dispersal field, prepare code-compliant CAD drawings, and file the OSSF permit with your county.

3

Installation

Tank set, aeration unit, chlorinator, dispersal field, and control panel wired and tested on your property.

4

Inspection & Handoff

We meet the county inspector for final sign-off, then walk you through operation and maintenance requirements before we leave.

Aerobic FAQ

Common questions

Your soil, lot size, and setbacks determine it, not personal preference. Dense clay, shallow rock, a high water table, or a small lot that cannot accommodate a standard drainfield are the most common reasons a site evaluator will specify aerobic. The soil test gives you the definitive answer, and we explain what we found and why before any design work begins.
Aerobic systems typically run higher than conventional installs because of the added treatment components, the control panel, and the ongoing maintenance contract Texas requires. Specific pricing depends on your site. We give you a firm number after the site evaluation, not a guess over the phone. For comparison, conventional residential installs in the Austin area run roughly $8,000 to $20,000, and aerobic systems generally sit above that range.
Yes. Texas requires all aerobic septic systems to have an active maintenance contract with a licensed provider. The system must be inspected multiple times per year and the contract kept current as long as the system operates. We explain what this involves before you commit to the system type, so you understand both the upfront cost and the ongoing obligation.
Installation itself runs a few days on site once the permit clears. The front-end work, soil evaluation, engineering design, and county OSSF permitting, typically takes two to six weeks depending on the county and their current review workload. We keep you updated at each stage so you are not wondering where things stand.
