Veazie STP - Secondary Wastewater Treatment Plant in Veazie, Maine

Veazie STP is a municipal wastewater treatment facility located in Veazie, Penobscot County, Maine, United States. The plant serves a population of approximately 1,850 people, classifying it as a small community system under US regulatory frameworks. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal wastewater facilities. Its designed capacity is 1,324.89 thousand cubic meters, with an actual discharge volume of 757.08 thousand cubic meters annually, indicating operational headroom. As a US facility, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Maine Department of Environmental Protection, ensuring compliance with effluent limits. The treated effluent is discharged into the Penobscot River, a major waterway in Maine that flows into Penobscot Bay and ultimately the Gulf of Maine. The river supports diverse aquatic life and is an important migratory corridor for Atlantic salmon and other diadromous fish. The plant's location within 50 km of the coast means its discharge contributes to the nutrient and pollutant load entering the coastal ecosystem.

The plant discharges into the Penobscot River, which flows south through Maine and empties into Penobscot Bay, part of the Gulf of Maine. The river supports a variety of fish species, including Atlantic salmon and alewife, and its estuary provides critical habitat for marine life. The watershed is ecologically sensitive due to its role in supporting migratory fish populations and coastal water quality.
