Dutchess Co Valley Dale STP - Pleasant Valley, New York Wastewater Treatment Plant

Dutchess Co Valley Dale STP is a wastewater treatment plant located in Pleasant Valley, Dutchess County, New York. It serves a small population of approximately 800 residents, reflecting its role in a rural community within the Hudson Valley region. The plant provides advanced treatment, which goes beyond the secondary treatment standard required by the US Clean Water Act. With a designed capacity of 143.85 million gallons per year and an actual discharge volume of 75.71 million gallons per year, the facility operates well within its capacity. As a US plant, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the New York State Department of Environmental Conservation. The treated effluent is discharged into a local water body that ultimately drains into the Hudson River, a major estuary flowing into the Atlantic Ocean. The plant's advanced treatment helps protect the Hudson River ecosystem, which supports diverse aquatic life and serves as a critical migratory corridor for fish.

The plant discharges into a tributary of the Hudson River, which flows south through eastern New York to New York Harbor and the Atlantic Ocean. The Hudson River estuary is ecologically sensitive, supporting diverse fish species, including striped bass and American shad, and providing important habitat for migratory birds. Advanced treatment at this plant helps reduce nutrient loading and protect water quality in this vital watershed.
