Texas OSSF Regulatory Framework

Texas regulates onsite sewage facilities under 30 TAC Chapter 285, administered by the Texas Commission on Environmental Quality. TCEQ sets the minimum statewide standards for OSSF design, installation, and maintenance. However, TCEQ has delegated permit authority to many Texas counties, including Travis County, which means Travis County administers its own OSSF permit program within the TCEQ framework.

Travis County's OSSF program operates under both TCEQ Chapter 285 and Travis County's local OSSF Order, which may impose additional requirements beyond the TCEQ minimums. Properties in the extraterritorial jurisdiction of Austin and other incorporated cities within the county may face additional requirements.

Travis County OSSF Permit Types

New OSSF Permit: Required for installation of a new onsite sewage facility on any property in unincorporated Travis County that isn't served by a public sewer system. Permit applicants must demonstrate that the site can support an OSSF through a site evaluation and, in many cases, a soil evaluation conducted by a licensed professional.

Repair Permit: Required when an existing OSSF needs repair or replacement of major components. Minor maintenance items typically don't require a permit, but replacing a tank, drainfield, or pump system does.

Construction Authorization: After permit approval, a Construction Authorization is issued when the site is ready for installation. This is the document that authorizes the actual work to begin.

Licensed Professional Requirements

Texas OSSF rules require that most OSSF work be performed by or under the supervision of licensed professionals:

Licensed Installer: OSSF installation must be performed by a licensed installer or under the direct supervision of one. Travis County enforces this requirement.

Registered Sanitarian or Licensed Engineer: For site evaluations and system designs on challenging sites, Travis County may require involvement of a licensed professional.

Maintenance Providers: Certain advanced OSSF types require maintenance by licensed providers under a maintenance agreement.

Confirm current licensing requirements with Travis County's OSSF program when planning your project.

Common OSSF Types in Travis County

The Hill Country soils and topography in much of Travis County present distinct OSSF design challenges. Shallow rock, caliche layers, and variable soil conditions mean that conventional drainfield systems aren't always feasible. Common OSSF types in the Austin metro area include:

Aerobic treatment units (ATUs): Common in Travis County for sites where conventional drainfields aren't feasible. ATUs require ongoing maintenance contracts and regular servicing.

Low-pressure dosing systems: For sites with adequate soil absorption capacity but where gravity distribution isn't practical.

Drip irrigation systems: Increasingly common in Travis County for sites with limited soil absorption area.

Conventional septic systems: Still permitted on suitable sites with adequate depth to limiting conditions and adequate soil absorption capacity.

The Austin Growth Context

Travis County's rapid population growth in the Austin metro area has created sustained high permit volume. Properties in fast-growing areas like the county's eastern and western corridors frequently see multiple OSSF permit applications per quarter. Extended permit review timelines are common during peak application periods.

Starting the OSSF permit process well before construction is planned is essential in Travis County's current growth environment.
