Marlborough T STP and On Site Syst - Milton, New York Wastewater Treatment Plant

Marlborough T STP and On Site Syst is a wastewater treatment facility located at 34 Dock Road in Milton, within the Town of Marlborough, Ulster County, New York. The plant serves a small population of 105 residents, reflecting its role in a rural or suburban community. As a secondary treatment plant, it provides biological treatment to remove organic matter and suspended solids, meeting typical standards for smaller facilities in the United States. The plant's designed capacity is 208.20 units, with a current discharge volume of 37.85 units, indicating it operates well below its maximum capacity. Under the U.S. Clean Water Act, such facilities are regulated through the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. The plant is expected to comply with state and federal requirements for secondary treatment. The treated effluent is discharged into a local water body, likely a tributary of the Hudson River, given the plant's location in the Hudson Valley. The Hudson River watershed is ecologically significant, supporting diverse aquatic life and serving as a migratory corridor for fish. The plant's operations help protect downstream water quality in the Hudson River estuary, which ultimately drains into the Atlantic Ocean.

The plant discharges into a local water body within the Hudson River watershed, which flows south to the Atlantic Ocean. The Hudson River estuary is a critical habitat for striped bass, American shad, and other migratory fish, and its health depends on proper wastewater treatment. The plant's secondary treatment reduces organic pollutants, helping maintain water quality in this ecologically sensitive region.
