Property Owner Permitting Responsibility
Property owners are responsible for the entire septic system permit process. If you have a contractor willing to provide information or services for different aspects of the process, that is acceptable. However, the property owner is responsible to see that the work is done to regulations.
The permitting fee covers the permit process, inspection of the installed system and maintaining a file for your septic permit.
Where/When Permits are Required
Septic System permits are required statewide, and Sheridan County requires that all permits in the county be completed through the Public Works office.
Permits are required when any change is made to a septic system. This includes any addition or subtraction of septic system components. Replacing pumps or solid piping without changing the layout of the system does not require a permit.
