If a disposal system design does not meet the minimum requirements of the Subsurface Wastewater Disposal Rules, it may be possible to obtain a variance to the Rules. There are two types of system variances: First Time System and Replacement System. There are also two levels of approval: Local and State.
All systems must meet the same basic site suitability, permitting, and inspection criteria as any other onsite sewage disposal system. A permit is required for installation of a subsurface wastewater disposal system or components thereof. A permit is valid for work commenced within 24 months after the permit is issued. (See: 30-A M.R.S. § 4215).
Please note: The Maine Drinking Water Program/Subsurface Wastewater Unit does not license Local Plumbing Inspectors (LPIs), nor do we appoint LPIs to municipal posts. For information on LPI licensing, contact the Maine State Fire Marshal's Office.
Subsurface wastewater disposal systems are used extensively throughout the State of Maine to treat and dispose of domestic and commercial wastewater.
The following are resources and guidance materials to assist Town office staff in the preparation and submittal of plumbing permits and the State's share of permit fees.

Maine is a predominantly rural state, and as such we rely heavily on decentralized sewage disposal facilities for human waste (septic systems). The State of Maine has regulated septic systems as a means of protecting public health since 1920.
