The regulation of septic tank systems is a State Law that is enforced by the Counties. There are many factors that are considered before a septic permit can be issued. These include:

Types of soil,
Amount of soil that can be used,
The size of the system that will be required,
Topography,
Landscape position,
Modifications to the site,
and more.

The variety of soils in Johnston County requires our staff to have a good working knowledge of rules and application to particular situations. Staff members who work with these rules are well-qualified and possess a strong technical sense. They understand the complexities of sewage disposal by septic tank systems.
