New Septic Installations
Building? Replacing a failed system? Buying raw land? Whatever the project, we design and install septic systems that pass TCEQ on the first try and last 30+ years. Free site evaluation. Honest numbers. No high-pressure sales — ever.
The two flavors of system, plain English
Conventional septic (gravity drainfield)
The classic. Wastewater flows from the house into a buried tank, solids settle, and the partially-clarified middle layer flows through perforated pipes into a drain field. Soil microbes finish the treatment. No power, no pumps, no moving parts in most cases. Just gravity and dirt doing the work.
Right for you if: half-acre+ lot, deep well-draining soil, far from creeks/lakes/wells, and you want the simplest long-term maintenance.
Aerobic treatment unit (ATU)
Treats wastewater to a much higher standard. Air pumps inject oxygen into the tank, dramatically speeding bacterial breakdown. A chlorine chamber disinfects the effluent. Treated water is sprayed across your lawn or distributed through subsurface drip lines.
Right for you if: tight lot, clay or rocky soil, high water table, near a creek/lake/well, or local jurisdiction requires it. Some Hill Country areas mandate aerobic.
Side-by-side comparison
| Factor | Conventional | Aerobic |
|---|---|---|
| Power required? | No | Yes — air pump runs continuously |
| Soil requirements | Deep, well-draining | Works on tight or clay-heavy soil |
| Lifespan | 30-40 years | 30+ years tank; pumps/spray heads 8-12 yrs |
| Visible above ground | Lids only | Spray heads in lawn |
What our install process looks like
- Free site evaluation — we walk the property, locate the existing system (if any), and assess soil, slope, setbacks, and access.
- Soil analysis — TCEQ requires a soil test before any system can be permitted. We pull samples, evaluate percolation, and determine which system types are viable.
- System design — our licensed designer drafts the layout: tank size, drain field dimensions or spray field design, riser placements, alarm wiring (aerobic), and inspection point access.
- Permit submittal — we handle TCEQ paperwork, county submittals, and any required HOA approvals. You don't lift a finger.
- Install — dig, drop the tank, lay the lines, backfill, pressure-test, electrical (aerobic), startup. 1-4 days depending on system type and weather.
- Final inspection + handoff — county/TCEQ inspector signs off. We walk you through the system, mark lid locations, and give you a written maintenance schedule.
Why customers pick the Wranglers
- Free site visit + written quote. No deposit, no commitment. We're either the right fit or we're not.
- Single point of contact. You talk to one Wrangler from quote through final inspection. Nobody hands you off.
- TCEQ first-pass rate. Our designs pass on the first inspection. No costly redos.
- Iron-clad warranty. If something we install fails within the warranty window, we make it right.
- We service what we install. No "find someone else for maintenance" — we keep your system running for the next 30 years.
Frequently Asked Questions
Do I need a permit?
Yes. Every onsite sewage facility in Texas requires a TCEQ-permitted design and inspection. We handle the entire permitting process — site evaluation, drawings, submittal, and final inspection.
How do I know which system I need?
A licensed designer evaluates your soil, lot size, and site conditions. The soil dictates the system, not your preference. We do the evaluation as part of every quote.
How long will the system last?
A well-maintained conventional system lasts 30-40 years. Aerobic tanks last similarly, but pumps and spray heads typically need replacement every 8-12 years.
