The Bexar County Permit Process
The OSSF permit application process in Bexar County follows the standard Texas delegated county program structure:
Site evaluation: Before a permit can be issued, the property must be evaluated to determine site suitability and the appropriate OSSF type. The evaluation assesses soil characteristics, available area, setbacks, and site-specific factors.
Application submission: Submit the permit application with site evaluation results, proposed system design, and required documentation to Bexar County's OSSF program.
County review: The county reviews the application against TCEQ Chapter 285 and the Bexar County OSSF Order. Complex sites or non-standard system types may require additional review time.
Permit issuance: If the application is approved, the county issues the permit authorizing installation.
Installation by licensed installer: A Texas-licensed OSSF installer performs the installation per the approved permit specifications.
Final inspection: Bexar County inspects the completed installation to confirm it was built as permitted.
San Antonio Metro Area Soil Conditions
The San Antonio area's geology includes significant areas of caliche, clay, and shallow rock that affect OSSF design. Conventional gravity drainfield systems aren't always feasible on Bexar County properties due to soil limitations. Common OSSF types approved in the county include:
Aerobic treatment units: ATUs are common in Bexar County for sites where conventional drainfields aren't practical. ATUs require maintenance contracts and regular professional servicing under Texas TCEQ rules.
Low-pressure dosing: For sites with adequate soil but where gravity distribution isn't appropriate.
Spray irrigation systems: Some Bexar County properties with ATUs discharge treated effluent via spray irrigation rather than drainfield absorption.
Conventional systems: On sites with suitable soil conditions and adequate depth, conventional systems remain the standard option.

- ATU owners must maintain a maintenance contract with a licensed maintenance provider
- Maintenance providers must service ATUs on the schedule specified in the maintenance contract
- Maintenance records must be kept and may be inspected by Bexar County
