Wilmington PCF Wastewater Treatment Plant, Vermont

Wilmington PCF is a municipal wastewater treatment facility located in Wilmington, Vermont, serving a small community of about 1,577 residents. The plant is situated in the Green Mountains region of southern Vermont, an area known for its forested terrain and cold-water streams. The plant provides secondary treatment, which is the standard biological treatment process required under the U.S. Clean Water Act for municipal facilities. With a designed capacity of 529.96 megaliters per year and an actual discharge volume of 359.61 megaliters per year, the plant operates at approximately 68% of its capacity, indicating adequate headroom for current flows. The treated effluent is discharged to a receiving water body that ultimately flows into the Deerfield River, a tributary of the Connecticut River. The Connecticut River drains into Long Island Sound, making this plant part of a larger watershed that supports diverse aquatic life and recreational uses downstream.

The plant discharges into a local stream that feeds the Deerfield River, which flows into the Connecticut River and eventually reaches Long Island Sound. The watershed supports cold-water fisheries, including native brook trout, and is an important migratory corridor for diadromous fish species such as American shad and Atlantic salmon.
