An OSSF is more commonly referred to as “septic system”, OSSF systems account for about 25% of all wastewater treatment in Bexar County and across the United States.

The service provider is responsible for submitting quarterly maintenance reports to the Designated Representative.
- Existing System Permit (Registration): Required when an existing system is found to not have a permit. In order to obtain a permit for an existing septic system, the property owner is required to hire a sanitarian or engineer to complete a site survey and septic design. A pump manifest (may not be older than one year) must also be submitted with a septic application.
Records of Permits
To request any records, constituents should please submit a request.
All installations of septic tanks are inspected at various points during the installation. The inspectors make sure the tank is installed according to regulation to ensure the system will work correctly.
When a complaint is received by Bexar County, or a Health and Safety problem is found in the field, an inspection is conducted. If a violation is verified, a notice of violation is sent by certified mail to the owner of the property detailing what violations were found at the site.
