Carmel T SD 7 STP Country Manor Wastewater Treatment Plant, Mahopac, New York

Carmel T SD 7 STP Country Manor is a wastewater treatment facility located at 35 Dahlia Drive in Mahopac, New York, within Putnam County. The plant serves a small population of 480 residents and operates as part of the municipal wastewater infrastructure for the Town of Carmel. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 174.13 thousand gallons per day and an average discharge volume of 121.13 thousand gallons per day, the facility operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all point source discharges. Advanced treatment is typical for plants in sensitive watersheds or where higher effluent quality is required. The treated effluent is discharged into a local water body that ultimately drains into the Hudson River watershed, which flows south to New York Harbor and the Atlantic Ocean. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the region.

The plant discharges into a tributary of the Hudson River, which flows into New York Harbor and the Atlantic Ocean. The Hudson River estuary supports diverse aquatic life, including migratory fish species such as striped bass and American shad. Advanced treatment at this plant helps reduce nutrient loading and protects the ecological health of the downstream watershed.
