Catskill T Smith s Landing SD4 Wastewater Treatment Plant, Town of Catskill, New York

Catskill T Smith s Landing SD4 is a wastewater treatment facility located in the Town of Catskill, Greene County, New York. The plant serves a small population of approximately 200 residents, reflecting its role as a decentralized treatment system for a rural community. It operates under the regulatory framework of the United States Clean Water Act, which mandates that all publicly owned treatment works meet secondary treatment standards as a minimum. The plant employs advanced treatment processes, indicating a higher level of pollutant removal beyond secondary treatment. This is typical for facilities discharging to sensitive water bodies or requiring nutrient removal. The designed capacity is 98.42 units, with a current discharge volume of 56.78 units, suggesting operational headroom. As a US facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the New York State Department of Environmental Conservation, which set effluent limits and monitoring requirements. The treated effluent from the plant ultimately enters the Hudson River watershed, which drains into the Atlantic Ocean via New York Harbor. The Hudson River is a major ecological corridor supporting diverse aquatic life, including migratory fish species such as striped bass and American shad. The plant's advanced treatment helps protect downstream water quality in this ecologically significant estuary.

The plant discharges into the Hudson River basin, which flows southward to New York Harbor and the Atlantic Ocean. The Hudson River estuary supports a rich ecosystem, including critical habitats for fish spawning and migratory birds. Advanced treatment at this facility helps minimize nutrient loading and protect water quality in this sensitive tidal river system.
