O&M 100: Subsurface Wastewater System Operator Training School


Proper operation and maintenance are key to assuring the longevity of onsite systems. This training school was developed to teach individuals how to provide quality service to owners of advanced onsite systems. Article 3 of 90A of the North Carolina General Statutes and the state wastewater rules require some wastewater treatment systems such as existing large subsurface disposal systems, newly permitted or repaired small onsite low pressure pipe (LPP) systems, drip irrigation systems, pressure-dosed sand filter systems, and peat biofilter systems to be operated by certified subsurface system operators. These requirements significantly increase the need for subsurface operator training and preparation for the examination for certification as a subsurface system operator.

Operator vs Installer/Inspector
The Subsurface Wastewater Operator School is an entirely separate certification program from the Onsite Wastewater Contractor (Installer/Inspector) certification. If you are unsure which certification you need, please contact us before registering.
