Danville WPCF - Secondary Wastewater Treatment Plant in Danville, Vermont

Danville WPCF (Water Pollution Control Facility) is a municipal wastewater treatment plant located in Danville, Vermont, United States. The facility serves a small population of 410 residents, reflecting the rural character of the area. It is situated in Caledonia County, in the northeastern part of the state. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal facilities of this scale. The designed capacity is 227.12 cubic meters per day, with an average daily discharge volume of 113.56 cubic meters, indicating the plant operates well within its capacity. As a US facility, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Vermont Department of Environmental Conservation. The treated effluent is discharged into local streams that drain into the Connecticut River watershed, which ultimately flows into Long Island Sound. This makes the plant's performance important for downstream water quality in both the Connecticut River and the Sound, supporting aquatic life and recreational uses.

The plant discharges into small tributaries of the Connecticut River, which flows south through New England into Long Island Sound. The Connecticut River watershed supports diverse aquatic ecosystems, including migratory fish species such as Atlantic salmon and American eel. The Sound is a vital estuary that provides habitat for marine life and supports commercial and recreational fisheries. Proper treatment at Danville WPCF helps protect these downstream environments from nutrient pollution and pathogens.
