A Class I certificate covers installation of which systems?

A Class I certificate specifically pertains to the installation of standard soil absorption systems. These systems are the most common type of septic systems used for treating household wastewater and are designed to filter and absorb effluent through the soil in a designated area known as a drain field. The certificate ensures that installers have the necessary training and knowledge to follow established guidelines and best practices, ensuring proper installation, which is crucial for maintaining public health and protecting the environment.

Alternative mound systems, septic pumps, and composting toilets fall under different classifications or require specialized knowledge and certification, which is why they are not covered by a Class I certificate. Each of these systems has its unique installation requirements and regulations, distinguishing them from standard soil absorption systems. Hence, a Class I certificate is directly focused on standard systems, indicating the regulatory and technical boundaries that govern their use and installation.
