2. What do I do if I wish to abandon a septic system?

Permit is not required.

Closure requirements: Remove all sewage from facility and dispose of the sewage in a lawful manner (pump the septic tank), disconnect and remove electrical and mechanical components, remove or collapse the top of any tank or containment structure, or fill it with dirt, sand, gravel or concrete. Cut and plug both ends of the abandoned sewer drain pipe between the building and septic tank. Notify the department within 30 days of closure.
