Homeowners, Landowners Examination

A homeowner or landowner who wishes to install their own sewer system is not required to be certified as a Class I installer, but must pass a written examination demonstrating knowledge of applicable rules.  The homeowner’s examination may be taken and graded at any local health department. A fee to administer the examination may be required.

 

 

Contact your Local Health Department before installing or modifying any existing onsite sewage disposal system.
