Marion Dept of Public Works Wastewater Treatment Plant, Massachusetts

The Marion Dept of Public Works operates a wastewater treatment plant serving the town of Marion, Massachusetts, a coastal community in Plymouth County. The facility is designed to handle a capacity of 1.00 million gallons per day, serving a population of approximately 1,969 residents. As a small municipal plant, it plays a key role in managing local wastewater and protecting public health. Plants of this scale in Massachusetts typically provide secondary treatment under the U.S. Clean Water Act. The facility is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Massachusetts Department of Environmental Protection, which set effluent limits to protect water quality. The plant's design capacity suggests it is sized appropriately for the community it serves. The plant's treated effluent is discharged into local receiving waters that ultimately drain into Buzzards Bay, an ecologically important estuary. Buzzards Bay supports diverse marine life, including shellfish beds and finfish, and is a vital resource for recreation and fishing. The plant's operations help maintain water quality in this sensitive coastal ecosystem.

The plant discharges into local streams that flow into Buzzards Bay, a large estuary on the southern coast of Massachusetts. Buzzards Bay is a productive marine environment that supports eelgrass beds, shellfish populations, and migratory fish species. The bay's health is closely tied to nutrient management from wastewater treatment, as excess nitrogen can lead to algal blooms and habitat degradation. The plant's location within 50 km of the coast underscores its role in protecting this valuable coastal resource.
