This site does not design, sell, or install septic systems. It connects you with independent, licensed local companies that do. The information below is general guidance for Smith County homeowners.
How installation works in Texas
- Site evaluation: a licensed site evaluator assesses soil, lot, and site conditions.
- Planning and permitting: the system is planned and permitted through the local authorized agent, in much of Smith County that is Smith County.
- Licensed installer: a TCEQ-licensed installer installs the system.
- Ongoing obligations: some systems, especially aerobic systems, have ongoing maintenance and contract obligations.
Conventional vs. aerobic systems
Conventional systems and aerobic treatment units suit different soils, lots, and household needs. A new residential system typically costs $10,000–$25,000 installed. That is a typical overall range, not a quote for your lot.
Questions worth asking any installer
- What system type do you recommend for this soil and lot, and why?
- What does the permit process involve here?
- What is included in your price, and what could change it?
- What ongoing maintenance will this system need?
- What records will I receive when the work is done?
If you are facing a drain field failure, check the repair page first. You may also want the aerobic service page, the cost guide, and the contact page.
When you request a quote, it helps to share your town, lot size, and permitting stage.
