Orange Co SD 1 Wastewater Treatment Plant, Town of Woodbury, New York

Orange Co SD 1 is a municipal wastewater treatment plant located in the Town of Woodbury, Orange County, New York. The facility serves a population of approximately 36,387 residents, placing it in the medium-agglomeration category under US regulatory frameworks. The plant is situated on River Road in the Village of Harriman, within the Hudson River watershed. As a US facility of this scale, Orange Co SD 1 operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the New York State Department of Environmental Conservation. These permits set effluent limits to protect water quality. Plants serving populations of this size typically employ secondary treatment as a minimum standard, with potential for advanced treatment depending on local requirements. The plant's treated effluent is discharged into a receiving water body that ultimately flows into the Hudson River, a major estuary and tidal river that drains into the Atlantic Ocean. The Hudson River supports diverse aquatic life and serves as a critical migratory corridor for fish species. The plant's operations are important for maintaining water quality in this ecologically significant watershed.

Orange Co SD 1 discharges into a tributary of the Hudson River, which flows southward through New York and empties into the Atlantic Ocean via New York Harbor. The Hudson River estuary supports a rich ecosystem, including striped bass, American shad, and Atlantic sturgeon. The plant's location within the Hudson River watershed means its effluent quality directly affects downstream habitats and recreational uses of the river.
