What to ask every contractor

Frequently asked questions about septic install & repair in Burnet County

How much does a septic system cost in Burnet County?
A conventional (gravity) septic system runs $6,000–$12,000 installed in Burnet County. Aerobic treatment units (ATUs) with sprinkler dispersal — required in poorly draining soils common in Hill Country — run $12,000–$18,000 plus $200/year maintenance. Soil evaluation and TCEQ permitting add $500–$1,200. Every quote should specify the OSSF type (conventional vs aerobic) and include the site evaluation cost separately.
Who is licensed to install a septic system in Texas?
Only TCEQ-licensed OSSF Installers (Class I or II) can legally install septic systems in Texas. Every installer on this page holds an active TCEQ license — verified from the TCEQ OSSF licensee database. Unlicensed installers cannot get your system permitted, and unpermitted systems create title problems when you sell the property. Always ask for the license number and check it at TCEQ.
How long does septic installation take?
From site evaluation to functional system, expect 4–8 weeks. The soil evaluation (perc test) takes 1–2 weeks, TCEQ permitting adds 2–3 weeks, and actual excavation and installation runs 3–5 days. Aerobic systems take slightly longer because the electrical and control panel need county inspection. Schedule installations for spring or fall — summer heat can slow tank curing.
Do I need a septic tank inspection before buying rural land?
Yes. If the property has an existing septic system, ask for a licensed OSSF Site Evaluator to inspect and provide a written report before closing. Costs $300–$600. Missing or failing systems can cost the buyer $10,000+ post-close. Every TCEQ-licensed installer on this page can either perform the inspection themselves or refer to a licensed evaluator.
What is the difference between conventional and aerobic septic?
Conventional (gravity/drain field) septic works when your soil percolates well — sandy or loamy soils absorb effluent naturally. Aerobic Treatment Units (ATUs) actively aerate and treat wastewater before dispersal, then spray-irrigate the treated effluent. Aerobic is required by TCEQ when soils are too tight (clay-heavy Hill Country), lots are too small, or water table is too high. Aerobic costs more upfront and requires annual maintenance contracts.
