Windham T Hamlet WWTP and On Sites is a municipal wastewater treatment facility located at 491 County Road 12 in the Town of Windham, Greene County, New York. The plant serves a population of approximately 1,200 residents, providing advanced treatment to protect public health and the environment. The facility employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 934.99 m³/day and an average daily discharge of 454.25 m³/day, the plant operates well within its capacity. As a US facility, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to safeguard water quality. The treated effluent is discharged into a local water body that drains into the Hudson River watershed, ultimately reaching the Atlantic Ocean. The plant's advanced treatment helps protect downstream aquatic ecosystems, including fish habitats and recreational waters in the Catskill region.

The plant discharges into a tributary of the Hudson River, which flows south to New York Harbor and the Atlantic Ocean. The Hudson River estuary supports diverse fish species, including striped bass and American shad, and is a critical migratory corridor. Advanced treatment helps reduce nutrient loading, protecting the river's ecological health and downstream water quality.
