Our installation process
Step 1 — soil evaluation by a licensed site evaluator. Step 2 — system design sized for bedroom count and meeting county setback rules. Step 3 — permit submission and county review (1–3 weeks). Step 4 — excavation, tank placement, and field construction. Step 5 — county final inspection and activation.
You get an as-built drawing showing exactly where everything is buried — invaluable at resale or for future repairs.
Frequently Asked Questions
How much does a new septic tank installation cost in DFW?+
Conventional gravity systems run $5,000–$10,000 installed. Aerobic treatment units (ATUs) range $8,000–$18,000 because of the treatment unit, electrical, spray field, and required maintenance contract.
How long does septic installation take?+
From contract to a working system, plan on 2–5 weeks: 1–3 weeks for soil eval, design, and county permit, plus 2–5 days of on-site construction and inspection.
Do you handle the county permit?+
Yes. We perform the soil evaluation, draw the system design, submit the OSSF permit application to your county designated representative, and coordinate the final inspection.
Can I choose between conventional and aerobic?+
Sometimes. Your soil class, lot size, and county code usually decide. Soft-soil lots over an acre often qualify for cheaper conventional. Clay-soil lots almost always require aerobic.
Is DIY septic installation legal in Texas?+
No. Texas requires a licensed OSSF installer for new construction and for replacements that change system type.
