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 as a public health issue 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 Subsurface Wastewater Team, within the MECDC's Division of Environmental Health, Drinking Water Program is charged under 42 MRS § 42 (3, 3-A, 3-B) to adopt rules which regulate subsurface sewage disposal systems, licensing of persons to evaluate soils for subsurface wastewater disposal systems, and inspection of plumbing and subsurface waste water disposal systems.
