Wiscasset Sewage Treatment - Wiscasset, Maine Wastewater Plant

Wiscasset Sewage Treatment is a municipal wastewater facility serving the town of Wiscasset, Maine, located in Lincoln County. With a population served of 1,235, it is a small-scale plant that provides secondary treatment to meet Clean Water Act standards. The plant has a designed capacity of 2,346.95 million gallons per year and currently discharges 416.40 million gallons per year. As a secondary treatment facility, Wiscasset Sewage Treatment meets the minimum federal requirement for municipal wastewater plants under the U.S. Clean Water Act. The plant operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Maine Department of Environmental Protection, which sets effluent limits to protect water quality. The plant's treated effluent is discharged into a local water body that ultimately drains to the Sheepscot River and then to the Gulf of Maine. The coastal location means the discharge must meet stringent standards to protect marine ecosystems, including shellfish habitats and migratory fish populations.

The plant discharges into a tributary of the Sheepscot River, which flows into the Gulf of Maine. The Sheepscot River estuary supports diverse aquatic life, including Atlantic salmon, alewives, and American eel. The coastal discharge location requires careful management to prevent nutrient enrichment and protect shellfish harvesting areas.
