Course Description

sewage containmentThe OSSF – Installer I course not only prepares students to sit for the On-Site Sewage Facilities Installer I license exam, it provides participants with the fundamentals surrounding proper installation, design, and operation of residential and commercial Installer I level on-site sewage facilities (OSSF). Once students successfully complete the course, they may apply directly with TCEQ to take the licensing examination at either a TCEQ Regional Office or at an approved Computer Based Testing (CBT) Center.

Special Note: Beginning August 12, 2020, TEEX will no longer administer the OSSF Installer I paper-based exam. After August 1, 2020, the Installer I exam will be available through CBT – see WWW901 for more details.


There are no prerequisites for this course.

During the course, your instructor will review any additional attendance requirements, for example a field exercise that cannot be missed.
