Erving Village Wastewater System - Secondary Treatment Plant in Erving, Massachusetts

Erving Village Wastewater System is a municipal treatment facility located at 45 East Main Street in Erving, Massachusetts, within Franklin County. The plant serves a small population of 545 residents, reflecting the rural character of this western Massachusetts community. As a secondary treatment facility, it provides biological treatment to reduce organic pollutants and suspended solids before discharge. The plant's designed capacity and discharge volume are both 492.10 units, indicating consistent operation at full capacity. Under the US Clean Water Act, facilities of this scale are typically regulated through National Pollutant Discharge Elimination System (NPDES) permits issued by the Massachusetts Department of Environmental Protection. These permits set effluent limits to protect water quality in the receiving water body. The treated effluent flows into the Millers River watershed, which drains into the Connecticut River and ultimately Long Island Sound. The Connecticut River basin supports diverse aquatic life, including migratory fish species such as American shad and Atlantic salmon. The plant's secondary treatment helps maintain water quality in this ecologically important river system.

The plant discharges into the Millers River, a tributary of the Connecticut River, which flows southward through Massachusetts and Connecticut before emptying into Long Island Sound. The Connecticut River watershed is a major ecological corridor supporting diverse fish populations, including diadromous species that migrate between freshwater and the Atlantic Ocean. Secondary treatment at this plant helps reduce nutrient loading and protect downstream habitats in the river and estuary.
