Carmel T SD 6 STP Ivy Hill - Advanced Wastewater Treatment in Town of Carmel, New York

Carmel T SD 6 STP Ivy Hill is an advanced wastewater treatment facility located in the Town of Carmel, Putnam County, New York. The plant serves a small population of 350 residents, reflecting its role in a rural or suburban community within the Hudson Valley region. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 189.27 units and a discharge volume of 109.78 units, the facility operates well within its capacity. As a US-based plant, it operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. The treated effluent is discharged into local waterways that ultimately drain into the Hudson River watershed. The Hudson River is a major estuary and ecologically significant water body that supports diverse aquatic life and provides habitat for migratory fish. The plant's advanced treatment helps minimize nutrient loading and protects downstream water quality in this sensitive ecosystem.

The plant discharges into local streams that flow into the Hudson River watershed. The Hudson River is a tidal estuary that supports a rich ecosystem, including striped bass, American shad, and Atlantic sturgeon. The advanced treatment at this plant helps reduce nutrient pollution, which is critical for preventing algal blooms and maintaining oxygen levels in the river and its downstream reaches into New York Harbor.
