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.
Part of the Maine Center for Disease Control and Prevention's Drinking Water Program, the Subsurface Wastewater Unit ensures subsurface wastewater disposal systems meet the requirements set forth in State and federal rules and statutes, as outlined in [42 MRS § 42 (3, 3-A, 3-B)].
The Subsurface Wastewater Unit oversees the following activities:
- Administers rules pertaining to subsurface wastewater disposal in Maine:
- State of Maine Subsurface Wastewater Disposal Rules (CMR 241),
- Rules for Appointment and Administration of Local Plumbing Inspectors (CMR 240), and
- Rules for Site Evaluators of Subsurface Wastewater Disposal Systems (CMR 245).
- Maintains copies of all plumbing and subsurface wastewater permits issued statewide.
- Licenses site evaluators for subsurface wastewater disposal systems pursuant to CMR 245.
- Provides reviews of engineering plans for compliance with or variance from departmental rules in support of the Division's various program areas.
- Provides resources and advice for partnering government agencies.
- Conducts site inspections to assist site evaluators, local officials, and property owners.
- Administers a voluntary subsurface wastewater disposal system installers certification program, in association with the Maine Department of Environmental Protection.
- Reviews and approves cemeteries, crematoria, crypts, and mausoleums.
