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, district office, or at the central office.  No fee is required.

 

 

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