Training for Septic System Installers and Inspectors


We continue to work with local and state health officials, as well as NC State and NC A&T State Universities, to monitor the evolving COVID-19 pandemic. Please know that training schedule changes are intended to protect the health and safety of our community while striving to provide the resources and services you need. We will continue to closely monitor the situation and act consistently with local, state and national recommendations.

2. Register for the initial certification training.

3. Register for additional training and the exam as needed, depending on certification type.  For additional 3-hour and 6-hour training opportunities offered by NC State University, see this website:
  • Installers:
    • For Grade 1 or 2, you’ll need one additional day of training (6 hours) after the 18-hour Intro. (There is no exam for Grades 1 or 2, only the training requirement.)
    • For Grade 3 or 4, you’ll need 2 additional days of training (9-12 hours) after the 18-hour Intro plus an exam. The exam is offered by the NCOWCICB on a different date.
  • Inspectors: After the school, you’ll need to pass an exam to finish your certification. The exam is offered by the NCOWCICB on a different date.
4. Keep up with your continuing education.  All certifications require continuing education training each year prior to Nov 15, in order to renew the certification for the next year. The CE requirement begins with the first year of certification.  For example, if you activate your certification in 2021, the NCOWCICB will require CE by Nov 15, 2021 to renew for 2022.  
  • Installers: Grade 1 and 2 Installers need 3 hours/year. Grade 3 and 4 Installers need 6 hours/year.
