Lunenburg WWTF - Secondary Wastewater Treatment Plant in Lunenburg, Vermont

Lunenburg WWTF is a municipal wastewater treatment facility located in Lunenburg, Vermont, United States. The plant serves a small population of 486 residents in the rural community of Lunenburg, situated in Essex County near the Connecticut River watershed. The plant provides secondary treatment, which is the standard level required under the US Clean Water Act for municipal wastewater facilities. With a designed capacity of 302.83 cubic meters per day and an average daily discharge of 227.13 cubic meters per day, the plant operates below its capacity. As a small facility, it is subject to EPA National Pollutant Discharge Elimination System (NPDES) permitting, typically administered by the Vermont Department of Environmental Conservation. The plant discharges treated effluent into a local water body that ultimately drains into the Connecticut River basin. The Connecticut River flows southward through New England and empties into Long Island Sound, an estuary of the Atlantic Ocean. The plant's operations help protect downstream water quality in this ecologically important river system, which supports diverse aquatic life and recreational uses.

The plant discharges into a tributary of the Connecticut River, which flows through Vermont, New Hampshire, Massachusetts, and Connecticut before reaching Long Island Sound. The Connecticut River watershed is a vital ecological corridor supporting migratory fish species such as Atlantic salmon and American eel. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting downstream water quality in this sensitive riverine and estuarine environment.
