What is one of the specific permits required for septic installation?

A Construction Authorization is a specific permit required for septic installation because it serves as official permission from the local health department or regulatory authority to proceed with the installation of a septic system. This permit indicates that the proposed installation has been reviewed and approved based on local regulations and health standards, ensuring that the system is designed and located properly to protect public health and the environment.

The other options, while related to the septic installation process, do not represent primary permits needed to initiate the installation. For example, an Inspection Permit may be required after installation to ensure compliance with regulations, but it does not grant authorization for the installation itself. A Design Permit focuses on the approval of the system design before installation begins, and Site Approval is often part of the initial assessments but does not serve as a standalone permit for installation. Each of these plays a role in the overall process but do not specifically authorize the construction of the septic system like the Construction Authorization does.
