Edgartown Department of Public Work Wastewater Treatment Plant, Massachusetts

The Edgartown Department of Public Work wastewater treatment plant serves the community of Edgartown on Martha's Vineyard, Massachusetts. With a designed capacity of 946.35 thousand cubic meters per year and an annual discharge volume of 454.25 thousand cubic meters, the plant provides secondary treatment for a population of 1,247 residents. As a secondary treatment facility, the plant meets the minimum standard required under the U.S. Clean Water Act for municipal wastewater treatment. The plant's capacity utilization suggests it operates well below its design capacity, indicating room for future growth or seasonal variations typical of coastal resort communities. The plant's proximity to the Atlantic Ocean (within 10 km) means treated effluent likely discharges into coastal waters or a nearby estuary. Martha's Vineyard is an ecologically sensitive area with important marine habitats, including shellfish beds and fish spawning grounds. The plant's secondary treatment helps protect these resources from nutrient pollution and pathogens.

The plant discharges into the coastal waters of Martha's Vineyard, which are part of the Atlantic Ocean ecosystem. This region supports diverse marine life, including commercially important fish and shellfish species. The secondary treatment process reduces organic matter and suspended solids, helping to maintain water quality in the surrounding coastal environment, which is also a popular recreational area.
