South Woodstock WWTF - Secondary Wastewater Treatment in Pomfret, Vermont

South Woodstock WWTF is a municipal wastewater treatment facility located in Pomfret, Vermont, United States. The plant serves a small population of 290 residents in the South Woodstock area, operating as part of the state's decentralized wastewater infrastructure. The facility provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for most municipal plants. With a designed capacity of 189.27 megaliters per year and an actual discharge volume of 113.56 megaliters, the plant operates well within its capacity. Vermont's wastewater facilities are regulated by the Vermont Department of Environmental Conservation under the National Pollutant Discharge Elimination System (NPDES) permit program. The plant's treated effluent is discharged into local waterways that drain into the Ottauquechee River, a tributary of the Connecticut River. The Connecticut River flows south to Long Island Sound, ultimately reaching the Atlantic Ocean. The facility plays a key role in protecting the water quality of these downstream ecosystems, which support diverse aquatic life and recreational uses.

The plant discharges into the Ottauquechee River watershed, which flows into the Connecticut River and then to Long Island Sound. This region supports cold-water fisheries, including trout species, and provides habitat for migratory fish. The watershed is ecologically sensitive due to its forested headwaters and agricultural lands, requiring careful management of nutrient and pathogen loads from wastewater.
