Onsite Wastewater Treatment Systems (Septic Systems)

An On Site Wastewater Treatment System (OWTS), commonly known as a septic system, treats the wastewater on an individual’s property. Septic systems are installed on properties that cannot be served by a wastewater utility. Adams County Health Department permits the installation, repair, and use of these systems in our jurisdiction.


All Onsite Wastewater Treatment System designers, soil evaluators, installers, inspectors, operation and maintenance providers, and pumpers will be required to obtain the National Association of Wastewater Technicians (NAWT) training course for the discipline they want to work in. More information about upcoming classes is available at www.cpow.net. For more information, contact your local field office. 

New Homeowner Training Materials

Through a grant from US EPA and in partnership with the Rural Community Assistance Program (RCAP), NOWRA is pleased to announce the release of training materials for educating property owners with an onsite wastewater treatment system (OWTS). Materials developed consist of a FREE interactive homeowner/public training module for residential owners and the public with best management practices to keep their septic systems functioning properly.

Concepts covered in the training course include: the importance of wastewater treatment, an overview of treatment in an onsite system, typical onsite system features, final treatment and dispersal, management, maintenance, safety, and system troubleshooting. While the training’s target audience is property owners who have an onsite system, the concepts are also applicable to the public, realtors, local health officials, and septic system professionals. The training materials are available on the NOWRA website.

The FREE interactive online course for homeowners is available on NOWRA's Online Learning Academy.
