Temporary License(s):


Temporary licenses were issued to individuals who successfully passed the Onsite Wastewater Installer Temporary Exam and submitted required documentation for licensure.


The temporary exam was offered to new and renewing installers while a new provider is being identified to offer the approved training course. Once the approved training courses are available, it is the installer’s responsibility to register, attend the training, and successfully pass the workshop exam.


Temporary licenses will terminate upon failure to attend the next available approved training. Installers who fail to attend the required training course, will not be issued another temporary license but may reapply for a license upon successful completion of the required training (LAC Title 51 Part XIII §737.G.).


Failure to meet the training requirement is in violation of the Public Health Sanitary Code as set forth in Louisiana Administrative Code Title 51 Part XIII §737, as follows:


Installer/Maintenance Provider Qualifications 

  1. All persons seeking to apply for a new license or renewal, must at their own expense, attend and successfully complete, a training course approved by the Sanitarian Services Section of the Office of Public Health, Department of Health and Hospitals, as a prerequisite for licensure. This course will be offered at least once annually.
  2. All licensees must successfully repeat this training course every five years.


This office will notify you when the approved training is available.
