Operator certification program

May 28, 2020: Update

Due to the COVID-19 pandemic, the DNR is currently evaluating the ability to safely provide exams to drinking water, wastewater, septage, and landfill operators, as well as well drillers and pump installers. It is the DNR’s intent to administer exams in late summer or fall, however the manner in which this will be done is still uncertain and the DNR is evaluating a variety of possibilities to ensure the health and safety of our customers. As a result, applications for these exams will not be available until the DNR finalizes plans for providing exams. More detailed information will be shared in the coming weeks as it becomes available.

The operator certification program is responsible for ensuring that various types of professional operators have adequate training to perform the necessary tasks at their facilities or businesses. Review certification and licensing requirements by selecting the appropriate link.
