Septic Installation services in Texas

237 licensed providers across 98 counties

Installing a new septic system in Texas requires an OSSF permit from TCEQ or a TCEQ-authorized county agent, following 30 TAC Chapter 285 requirements. A licensed Site Evaluator must first perform a site evaluation including soil borings and percolation testing to determine which system type the site can support. TCEQ recognizes several licensed professional categories including Installer I (standard systems), Installer II (all system types including aerobic), and Designated Representatives who manage the permitting process for companies.

Conventional septic installation in Texas runs $4,000-$9,000, covering the tank, drain field, and labor. Aerobic treatment units with spray distribution — increasingly common due to soil limitations — can cost $8,000-$15,000 or more. Hill Country properties over limestone bedrock may require surface spray aerobic systems that add $3,000-$5,000 over conventional costs. The DFW metroplex's heavy Blackland Prairie clay frequently demands engineered alternatives. Properties in the Edwards Aquifer recharge zone (Bexar, Comal, Hays, Travis, Williamson, Uvalde, Medina, Kinney counties) must meet enhanced TCEQ and Edwards Aquifer Authority standards to protect groundwater.

Texas requires a mandatory 2-year initial maintenance contract for all aerobic and secondary treatment systems, provided by the installer or manufacturer. After the initial period, property owners must maintain a contract with a TCEQ-licensed Maintenance Provider for ongoing 3x/year inspections. Permit fees range from $200-$600 depending on the county. The 10-acre exemption may apply to single-family dwellings on properties of 10 acres or more, though a licensed site evaluation must confirm no nuisance will be created and all components must be at least 100 feet from property lines.
