SO BERWICK SEWAGE PLANT - South Berwick, Maine Wastewater Treatment

SO BERWICK SEWAGE PLANT is a municipal wastewater treatment facility located in South Berwick, Maine, United States. The plant serves a population of approximately 2,070 residents in this small New England community, situated in York County near the border with New Hampshire. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater facilities. With a designed capacity of 1,415.74 thousand gallons per day and an average discharge volume of 908.50 thousand gallons per day, the plant operates below its full capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into a local water body that ultimately drains into the Great Works River, a tributary of the Piscataqua River, which flows into the Atlantic Ocean via the Gulf of Maine. This coastal watershed supports diverse aquatic life and is an important ecological corridor for migratory fish species.

The plant discharges into the Great Works River, which flows into the Piscataqua River estuary and then into the Gulf of Maine. This coastal watershed supports diverse aquatic life, including diadromous fish species such as Atlantic salmon and river herring. The estuary provides critical nursery habitat for marine species and is influenced by tidal flows, making water quality management essential for ecosystem health.
