Onondaga Co Oak Orchard WWTP - Town of Clay, New York Wastewater Treatment

Onondaga Co Oak Orchard WWTP is a municipal wastewater treatment facility located in the Town of Clay, Onondaga County, New York. The plant serves a population of approximately 42,911, placing it in the medium-to-large agglomeration category under US regulatory frameworks. As a US facility, the plant 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. For plants serving over 10,000 people, secondary treatment is typically required, with additional nutrient removal standards in sensitive watersheds like the Lake Ontario basin. The treated effluent from the plant flows into nearby streams and ultimately reaches Lake Ontario, part of the Great Lakes system. This watershed supports diverse aquatic life and provides drinking water for millions. The plant plays a critical role in protecting water quality in this ecologically and economically significant region.

The plant discharges into tributaries of the Lake Ontario watershed, which drains into the St. Lawrence River and eventually the Atlantic Ocean. Lake Ontario is a vital freshwater resource supporting fisheries, recreation, and municipal water supplies. The region is sensitive to nutrient pollution, which can cause algal blooms and hypoxia, making effective wastewater treatment essential for ecosystem health.
