OSSF Licensing and Registration Overview
State Regulations:
To operate as an OSSF installer, apprentice, maintenance provider or maintenance technician in Texas, you must be licensed or registered by the TCEQ.
- Designated Representative License: must be licensed by the TCEQ and work for an authorized agent of the TCEQ. They perform site evaluations (when it is part of their job duties), complaint investigations, system evaluations, and inspections of OSSFs that have been issued an authorization to construct to ensure the installation of the OSSF meets the criteria established by the TCEQ, or by the Authorized Agent Order approved by the TCEQ, whichever is more stringent.
- Site Evaluator License: must be licensed by the TCEQ or hold a Texas Professional Engineer license. They are authorized to perform preconstruction site evaluations to determine a site's suitability for a particular OSSF system and identify all features, within or near the location where an OSSF is to be installed, that could be contaminated by the OSSF or could interfere with the proper operation of the system.
- Installer I License: authorized to install standard OSSF systems (septic tanks, absorptive drainfields, unlined ET drainfields, leaching chambers, gravel-less pipe, and pumped effluent drainfields).
- Installer II License: authorized to install all types of OSSF systems.
- Apprentice Registration: Authorized to represent the supervising installer at the job site. However, they may only perform OSSF installation services under the constant, direct supervision of a licensed installer, either on-site or by radio or other means of direct communications. If supervision is not on-site, the license installer must visit the job site at least once each workday to verify the work of the apprentice is being performed in accordance with State or Authorized Agent requirements.
- Maintenance Technician Registration: authorized to perform services associated with OSSF maintenance but only under the direct supervision and direction of the maintenance provider either on-site or by direct communication with the maintenance provider.
- Maintenance Providers License: authorized to provide service or maintenance to on-site disposal systems using aerobic treatment.
