On-Site Wastewater


The goal of the On-Site Wastewater program is to reduce the potential for the spread of disease through improper treatment and disposal of human waste. Potential contamination of ground and surface waters is both an environmental and public health concern. Proper disposal of wastewater is critical as the population expands in rural areas of our state.

Training classes: Due to COVID-19, we have postponed our Certified Installer & Pumper classes indefinitely. We will update this page once we are able to offer classes.
