Yorktown T YHeights SD 1 and Decentralized Onsite WWTS - Town of Yorktown, New York Wastewater Treatment

Yorktown T YHeights SD 1 and Decentralized Onsite WWTS is a municipal wastewater treatment facility located in Yorktown Heights, Westchester County, New York. The plant serves approximately 12,000 residents of the Town of Yorktown, providing essential wastewater management for this suburban community in the Lower Hudson Valley. As a US facility serving a population of 12,000, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting. For agglomerations of this size, secondary treatment is typically required, with additional nutrient removal if discharging to sensitive waters. The plant's designed capacity is 1.00 million gallons per day, reflecting its scale. The plant discharges treated wastewater into local waterways that ultimately drain to the Hudson River estuary, a major tidal river flowing into the Atlantic Ocean. The Hudson River supports diverse aquatic life, including migratory fish species, and is an ecologically significant water body in the region.

The plant's treated effluent enters local tributaries of the Hudson River, which flows south through the Hudson Valley to New York Harbor and the Atlantic Ocean. The Hudson River estuary is a critical habitat for striped bass, American shad, and other migratory fish, and its water quality is protected under state and federal regulations. The surrounding watershed includes mixed suburban and forested land uses.
