Maine is a predominantly rural state, and relies heavily on decentralized sewage disposal facilities for disposal of human waste, i.e., septic systems. The State of Maine has regulated septic systems since 1920 to varying degrees. Over the years, the Maine State Plumbing Code, Subsurface Wastewater Disposal Rules (Rules) in their various versions have been administered by the Maine Center for Disease Control and Prevention (MECDC) and its predecessors.
The MECDC has been and continues to be responsible for the Rules because they have historically been viewed as a public health code, rather than an environmental regulation.
The Subsurface Wastewater Team, within the MECDC's Division of Environmental Health, Drinking Water Program promulgates and administers the Rules. Our mission is to minimize health and safety hazards associated with improperly installed subsurface waste water disposal systems.
What's New at the Subsurface Wastewater Team
On this page:
When installed inside a building advanced treatment devices are regulated by and subject to the Maine Internal Plumbing Rules. Associated disposal fields are still regulated by the Subsurface Wastewater Disposal Rules. For more information on the Internal Plumbing Rules LPIs are advised to contact the Plumbers Examining Board at (207) 624-8603.
The HHE-239 Form, Certificates of Approval, has been updated. This form is used by Local Plumbing Inspectors to keep track of installation inspections.
The Subsurface Wastewater Team is reviewing policies which are either outdated or have been superseded by revisions to the Subsurface Wastewater Disposal Rules. More information.
The Subsurface Wastewater Team has scanned all the hardcopy product files in our possession and uploaded them as Adobe PDF files to this website. The PDF files are linked from the new Products page. No confidential information was copied to our knowledge.
A new checklist is available to assist Local Plumbing Inspectors during system installation inspections.
The PowerPoint presentations and video for the 2013 Basic and the Beyond the Basics workshops are available for viewing and downloading on our training page.
